This chapter explains how to install the Strata DK14 system. It includes information on site
requirements, wiring diagrams, and step-by-step instructions on how to install the unit(s), the
ground wiring, AC power cabling, reserve power (battery backup) cabling, and PCB cabling.
Inspection
1. When the system is received, examine all packages carefully and note any visible damage. If
any damage is found, do not open the packages. Contact the delivery carrier immediately and
make the proper claims.
2. After unpacking (and before installing), check the system against the packing list and inspect
all equipment for damage. If equipment is missing or damaged, contact your supplier
immediately.
3. Be sure to retain original packaging materials for re-use when storing or transporting system
hardware.
Packaging and Storage
CAUTION!
When handling (installing, removing, examining) PCBs, do not touch the back
(soldered) side or edge connector. Always hold the PCB by its edges.
When packaging and storing the system, remove PCBs from the system cabinet (the power
supply may remain installed in the cabinet for storage and shipment). PCBs should be
packaged in their original antistatic bags for protection against electrostatic discharge. Be sure
to package equipment in its original shipping containers.
Site Requirements
This section defines the installation site requirements necessary to ensure a proper operating
environment for the DK14. Also included are grounding requirements. (Table 1-1 for electrical/
environmental characteristics.)
Strata DK I&M 5/00

DK14 Installation
Site Requirements
Input Power
The system requires an input power source of 115VAC ± 10VAC, 50/60 Hz, 10 amps. The AC
outlet is recommended to be dedicated and unswitched, with a solid third-wire ground. (See "AC
Power and Grounding Requirements" on Page 1-3 for details).
This is to eliminate interference from branch circuit motor noise or the like, and to prevent
accidental power-off. To avoid accidental power turn-off, Toshiba recommends that you do not use
an On/Off wall switch on this dedicated AC circuit.
For the DK14, a reserve power source (two customer-supplied 12-volt batteries) may be connected
to the system to serve as a power failure backup.

DK14 Installation
AC Power and Grounding Requirements
AC Power and Third-wire Ground Test
Test the "third-wire ground" for continuity by either measuring the resistance between the third
prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm), or by using a
commercially available earth ground indicator. If neither procedure is possible, perform the
following earth ground test procedure.
WARNING!
Hazardous voltages that may cause death or injury are exposed during the
following test. Use great care when working with AC power line voltage.
To perform the earth ground test procedure
1. Obtain a suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires)
on the wall outlet. The reading obtained should be between 100~125VAC.
3. Move one of the meter probes to the third terminal (green wire ground). Either the same
reading or a reading of zero volts should be obtained.
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe
to the second voltage terminal.
CAUTION!
If a reading of zero volts is obtained on both voltage terminals (white wire to
green wire, black wire to green wire), the outlet is not properly grounded. Omit
Steps 5 and 6, and see following CAUTION!
5. If a reading of zero volts on one terminal, and a reading of 105~125VAC on the other terminal
is obtained, remove both probes from the outlet.
6. Set the meter to the "OHMS/Rx1" scale. Place one probe on the ground terminal, and the other
probe on the terminal that produced a reading of zero volts. The reading should be less than 1
ohm.
CAUTION!
If the reading is more than one ohm, then the outlet is not adequately grounded.
If the above tests show the outlet AC voltage is not in range or is not properly
grounded, the condition should be corrected (per Article 250 of the National
Electrical Code) by a qualified electrician before the system is connected.
Alternate or Additional Ground
If the "third-wire" AC ground can not practically be improved or if extreme motor noise or other
disturbance causes system malfunction, or if local area lightning storms exist, a separate direct
ground may be warranted.
Connect a separate earth ground from a cold water pipe or earth grounding rod directly to the FG
screw terminal on the DK14 power supply (see Figure 1-2).
This chapter provides the instructions necessary to mount the DK14 Key Service Unit (KSU).
Instructions are also provided on how to remove and replace the power supply.

The DK14 KSU can support up to four optional PCBs, including:
A maximum of two QCDU2s: each one provides one CO line circuit and two digital telephone
circuits.
A QSTU2 which provides two standard telephone circuits (ports).
A QRCU2 which provides three circuits to receive DTMF tones (required for DISA and
devices connected to QSTU2s), and three circuits to detect busy tone (required for the ABR
feature).
A WSIU which provides a port for either a Station Message Detail Recording (SMDR) device
or a maintenance terminal or modem, or Caller ID interface.
The KSU does not come from the factory with any option PCBs installed. Each of the option
PCBs must be installed in specific locations. (See Figure 1-9.)
PCB Option Considerations
PCBs may be configured for a variety of hardware and software options. Hardware options are
defined as either internal (generally related to optional PCB subassemblies) or external (related to
connection of peripheral equipment such as background music, voice mail, etc.). Hardware and
software options for each PCB are identified in the individual PCB installation procedures in this
chapter.
PCB Hardware Options. Each PCB must be configured for the applicable hardware options prior
to installation of the PCB. Configuration instructions for internal hardware options are provided in
the individual PCB installation procedures in this chapter. Configuration instructions for external
hardware options are provided in Chapter 12 Peripheral Installation.
PCB Software Options. After installation of the PCBs in the KSU, configure the PCBs for
software options through programming. A programming overview for each PCB is provided in the

iguration
This chapter explains how to configure a Strata DK40i, R4.3 system. It also provides tables for
recording the hardware and station devices that make up the system.
The DK40i Base and Expansion cabinets provide an extensive number of features for a telephone
system of its size. A list of the DK40i features and capacities is provided in Tables 2-2~2-3.
Important!
System configuration can be complex and time consuming. For best results:
Use DKi Quote, version 4.3.1 to provide easy, fast automated configuration of
DK40i without the T1, PRI and ACD features. See the DKi Quote User Guide for
more information.
If the above software is not available, use the Worksheets in this chapter.

1. There are four universal slots in the DK40i expansion unit.
2. In the D40i, DID, Tie, and BRI lines do not use up station ports as in DK40 and the DK424, R4. Each BRI line circuit
uses up to two CO lines of system capacity.
3. Each S/T type circuit requires an NT-1 device when connected to a Central Office BRI line circuit.

1. The DKT2004-CT and DKT2104-CT cordless telephone connects as either a stand-alone or to a digital 2000-series
telephone.
2. Speaker OCA, PDIU and RPCI capacity is determined by PDKU 2B channel slot availability and power supply
limits.
3. To install the maximum of 28 total DKTs and EKTs, up to 16 of the stations can be EKTs and at least 8 of the stations
must be DKTs.
4. In the DK40i, BRI station circuits do not use up CO line numbers as in the DK424, R4. Each BRI station circuit uses
up to two station ports of system capacity. Toshiba BRI (S/T) station circuits are passive and allow up to two devices
to share a circuit. BRI-U allows one device per circuit.

Base Key Service Unit (KSU)
Base Key Service Unit (KSU)
Station and CO Lines
The DK40i Base KSU comes equipped with eight digital telephone station circuits. One of four
optional PCBs can be added to provide either four loop start or DID lines, or two ISDN BRI S/T or
BRI-U circuits (Table 2-4). An optional TCIU2 Printed Circuit Board (PCB) can be added to the
Base KSU loop start line PCB to provide Caller ID interface. An optional KSTU2 PCB can be
added to provide four standard telephone circuits (ports).
Note
An Expansion KSU can be added to the DK40i to increase the system capacity to 28
station ports and 12 lines.
Peripherals
The DK40i Base KSU can support a number of peripherals, which are not considered as stations or
lines and do not affect the maximum station and line capacities. The DK40i Base KSU comes
standard with built-in interfaces for connecting the following dealer-supplied equipment: an
amplifier and speaker for paging and night ringing, Music-on-Hold (MOH) source, reserve power
batteries, and emergency standard telephone for system power failure occurrences when using
loop start lines in the base cabinet.
A relay contact is also provided to control one of the following peripherals: MOH source, night
bell, or page amplifier mute control.
An optional KSTU2 PCB provides an alternate background music source interface. The music
plays through Toshiba telephone speakers, as opposed to the external page speakers.
The optional TSIU PCB provides two RS-232 interface ports to connect two of four options: a
DKAdmin PC (or external modem for remote maintenance); or VM SMDI; or ACD/MIS PC; or an
SMDR port to connect a call accounting device or printer. If more than two interface ports are
needed, an optional interface PCB can be installed in the expansion cabinet to provide up to four
RS-232 interface ports.

a TTY/RS-232 port which can connect to a customer-provided VM SMDI or external modem
for remote maintenance, or to a local PC with DKAdmin
connectors for an internal modem (IMDU) for remote maintenance and administration
RSSU
The RSSU provides one TTY/RS-232 port for a connection to a VM SMDI or customer-provided
external modem for remote maintenance, or to a local PC with DKAdmin. The RSSU does not
support SMDR or IMDU.
Any device that connects to the PIOU, PIOUS, or RSSU should not be considered a station and
does not affect the system's station capacity.

Configuration Considerations
Configuration Considerations
The following considerations should be taken into account when filling out the tables in
"Worksheet 1 System PCB Assignment Guide" on Page 2-11.
Base Cabinet
1. Only one line PCB (TCOU, TDDU, TBSU or TBUU) can be installed in the Base cabinet.
2. If TBSU or TBUU is installed, each circuit can be configured independently as a station side
DK40i Conf
or line side BRI circuit.
3. Each TBSU or TBUU ISDN BRI circuit uses two station ports and no line numbers if the
circuit is configured for the station side.
iguration
4. Each TBSU or TBUU ISDN BRI circuit will use two line numbers and no station ports if the
circuit is configured for the line side.
5. TDDU provides four DID lines and does not use station ports.
6. Install TCIU2 for Base KSU CO (TCOU) Caller ID Lines.
CAUTION!
To prevent system malfunction, do not install TCIU1 in the DK40i system.
7. K5RCU, K5RCU2 or K4RCU3 must be installed when using built-in automated attendant
(AA), ACD, ACD/MIS, Voice Mail, ABR, Stratagy DK, standard telephone ports, Tie lines,
DISA, or DID Lines.
8. KKYS1~3 is required for built-in AA; KKYS2 for AA and ACD; KKYS3 for AA, ACD/MIS.
9. TSIU can be used for an RS-232 Maintenance (TTY) port, SMDI, ACD/MIS or SMDR port.
RSIU cannot be used.
Expansion Cabinet
1. Each RDDU provides four DID lines and does not use station ports. This is different from the
DK40 and DK16e in which each DID circuit used a line number and station port.
2. Each REMU to PEMU provides the four Tie lines and does not use station ports. This is
different from the DK40 and DK16e in which each Tie line circuit used a line number and
station port.
3. Stratagy DK can be installed in the expansion unit to provide two, four, six or eight built-in
Automated Attendant/Voice Mail circuits. Always install Stratagy DK in slot 15, 16, or 17; do
not install Stratagy DK in slot 18. Program the Stratagy VM ports as if they were standard
telephone ports connected to an external VM device. All models of Stratagy DK use up eight
station ports.
4. Install RCIU2/RCIS in slot 17 (only) for Expansion KSU (RCOU/RCOS or RGLU2) Caller
ID Lines.
CAUTION!
To prevent system malfunction, do no install RCIU1 in DK40i, and RCIU2
must not be installed in slot 18.
5. If required, install PIOU, PIOUS, and RSSU in any slot.
Strata DK I&M 5/00
2-15

DK40i Configuration
Configuration Considerations
6. Speaker OCA and RPCI/DIU data applications can only be installed on digital telephone ports
in the DK40i Base KSU and slots 15 and 16 of the DK40i Expansion KSU (24 maximum).
7. RWIU can be installed in any of the expansion cabinet slots (15, 16, 17, and 18) to support up
to 8 StrataLink handsets. If there are 9 to 16 handsets, the RWIU must be installed in slot 15
and slot 16 must be vacant. This system cannot support 24 or 32 handsets because of a port
limitation.
8. RDTU can provide 8 or 12 T1 lines software programmable. Install RDTU in slot 15. Slots
16, 17, and 18 can be used for other PCBs.
DK40i ISDN
Configure DK40i, ISDN BRI PCBs (RBSU, RBSS, TBSU and TBUU) with the following rules
1. TBSU or TBUU installs in the base cabinet to provide 2 BRI circuits, each circuit can be
station side or line side in any combination. See the ISDN section in this manual for more
information regarding TBSU and TBUU.
2. If a TBSU or TBUU is installed, TDDU or TCOU cannot be installed. Only one PCB (TSBU,
TCOU or TDDU) can be installed in the DK40i base cabinet for a given DK40i configuration.
3. RBSU or RBUU installs in any expansion unit slot to provide 2 BRI circuits which can be
station side or line side in any combination.
4. RBSS installs on an RBSU and RBUS install on an RBUU in any expansion unit slot; each
PCB combination provides 4 BRI circuits total. RBSS can be station side only; RBSU can be
station or line side.
5. Each ISDN BRI circuit uses two station ports and no line numbers if the circuit is configured
for station side. This is different from the DK424 ISDN in which each BRI circuit uses two
station ports and two line numbers when the circuit is configured for station side.
6. Each ISDN BRI circuit will use two line numbers and no station ports if the circuit is
configured for the line side. This is different from DK424 ISDN, in which each BRI circuit
uses two station ports and two line numbers when the circuit is configured for line side.
7. Total maximum BRI circuits on the station side is 10 (20 ports/B-channels max.).
8. Total maximum BRI circuits on the CO line side is 6 (12 lines/B-channels max.).
9. RPTU can provide 8 or 12 PRI lines software programmable. Install RPTU in slot 15. Slots
16, 17, and 18 can be used for other PCBs.

DK40i Configuration
Worksheet 2 System Power Factor Check
Worksheet 2 System Power Factor Check
The DK power supply was engineered for maximum cost efficiency to provide power for the most
configurations. Because of this design, some power limitations exist when using old electronic-
type telephones, telephone option hardware, or newer PCBs, such as RWIU, TBSU, RBSU/RBSS.
Telephone/Device PFs
The power supply of each KSU supplies a limited amount of power. For each KSU, calculate the
total Telephone/Device Power Factor (PF) and add it to Table 2-24. (See Table 2-10 for PCB
DK40i Conf
quantity and type.)
The TBSU, RBSU/RBSS and RWIU PCBs require more power from +5VDC than other PCBs;
therefore, it is necessary to calculate the +5VDC and -24VDC PF on DK40i.
iguration
Important!
A system PF check must be performed for all configurations. See Table 2-19 for the

Upgrades
DK40i, (R4.1) can be upgraded to DK40i (R4.3) by changing a ROM chip (order the DK40i, R4.3
Upgrade kit). DK40i, R1 is the only DK that can be upgraded to DK40i, R2. To upgrade DK40i R1
to the DK40, R4.3, the DK40i R4.1 base cabinet must be DKSUBI40A V.1B or higher. If the Base
KSU is DKSUB40IA V.1A, it cannot be upgraded for ACD, T1 or PRI, etc. See FCC label on the
side of the cabinet.
Note
DK40i systems which do not require an upgrade to allow T1, PRI, etc., are identified as
DKSUBI40A V.2A or higher.
The Strata DK16 Base KSU cannot be upgraded to a DK16e, DK40 or DK40i and the DK16
Expansion Cabinet is not compatible with the DK16e, DK40 or DK40i. The Strata DK40i is not a
modification of the DK40, but rather a completely new system.
The DK40i uses the DK40 expansion cabinet. The DK16e can be upgraded to DK40 by changing
a ROM chip, but not to a DK40i. The DK40 base cabinet cannot be upgraded to a DK40i.
DK16/DK16e/DK40/DK40i Component Compatibility
The original DK16 two-loop start CO line and four-digital station interface unit (KCDU1A) is
forward compatible with the DK16e or DK40i.
Most DK16 PCBs are not compatible with the DK40i, including the four-port Standard Station
Interface Unit (KSTU1A), four-circuit DTMF/ABR Tone Detection Receiver Unit (K4RCU1A or
K4RCU2A), and the Auto Attendant feature cartridge (KFCU1A).
Four of the Strata DK40i PCBs are backward compatible with the DK16, DK16e and DK40. They
are: KSTU2A, K4RCU3A, K5RCU and K5RCU2. The DK40i Expansion Cabinet is also
backward compatible with the DK16.

This chapter explains how to install the Strata DK40i, Release 4.3 system. It includes information
on site requirements, wiring diagrams, and step-by-step instructions on how to install the unit(s),
the ground wiring, AC power cabling, reserve power (battery backup) cabling, and PCB cabling.
D
Inspection
K40
i Installation
1. When the system is received, examine all packages carefully and note any visible damage. If
any damage is found, do not open the packages. Contact the delivery carrier immediately and
make the proper claims.
2. After unpacking (and before installing), check the system against the packing list and inspect
all equipment for damage. If equipment is missing or damaged, contact your supplier
immediately.
3. Be sure to retain original packaging materials for re-use when storing or transporting system
hardware.
Packaging and Storage
CAUTION!
When handling (installing, removing, examining) PCBs, do not touch the back
(soldered) side or edge connector. Always hold the PCB by its edges.
When packaging and storing the system, remove PCBs from the system cabinet (the power
supply may remain installed in the cabinet for storage and shipment). PCBs should be
packaged in their original antistatic bags for protection against electrostatic discharge. Be sure
to package equipment in its original shipping containers.
Site Requirements
This section defines the installation site requirements necessary to ensure a proper operating
environment for the DK40i. Also included are grounding requirements.
Strata DK I&M 5/00
3-1

DK40i Installation
Site Requirements
Input Power
The system requires an input power source of 115VAC ± 10VAC, 50/60 Hz, 15 amps. The AC
outlet is recommended to be dedicated and unswitched, with a solid third-wire ground. (See "AC
Power and Grounding Requirements" on Page 3-4.)
This eliminates interference from branch circuit motor noise or the like, and to prevent accidental
power-off. To avoid accidental power turn-off, Toshiba recommends that you do not use an On/Off
wall switch on this dedicated AC circuit.
For the Strata DK40i, a reserve power source (two customer-supplied 12VDC batteries) may be
connected to the system to serve as a power failure backup.
Clearance and Location
The minimum clearance requirements for the Strata DK40i Base and Expansion KSUs are shown
in Figures 3-1 and 3-2. Refer to Page 3-5 for DK40i KSU mounting instructions.

DK40i Grounding Diagram
AC Power and Third-wire Ground Test
Test the "third-wire ground" for continuity by either measuring the resistance between the third
prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm), or by using a
commercially available earth ground indicator. If neither procedure is possible, perform the
following earth ground test procedure.
WARNING!
Hazardous voltages that may cause death or injury are exposed during the
following test. Use great care when working with AC power line voltage.
To perform the earth ground test procedure
1. Obtain a suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires)
on the wall outlet. The reading obtained should be between 100~125VAC.
3. Move one of the meter probes to the third terminal (green wire ground). Either the same
reading or a reading of zero volts should be obtained.
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe
to the second voltage terminal.
CAUTION!
If a reading of zero volts is obtained on both voltage terminals (white wire to
green wire, black wire to green wire), the outlet is not properly grounded. Omit
Steps 5 and 6, and see following CAUTION!
5. If a reading of zero volts on one terminal, and a reading of 100~125VAC on the other terminal
is obtained, remove both probes from the outlet.
3-4
Strata DK I&M 5/00

DK40i Installation
KSU Mounting Considerations
6. Set the meter to the "OHMS/Rx1" scale. Place one probe on the ground terminal, and the other
probe on the terminal that produced a reading of zero volts. The reading should be less than 1
ohm.
CAUTION!
If the reading is more than one ohm, then the outlet is not adequately grounded.
If the above tests show the outlet AC voltage is not in range or is not properly
grounded, the condition should be corrected (per Article 250 of the National
Electrical Code) by a qualified electrician before the system is connected.
Alternate or Additional Ground
If the "third-wire" AC ground can not practically be improved or if extreme motor noise or other
disturbance causes system malfunction, or if local area lightning storms exist, a separate direct
ground may be warranted.
Connect a separate earth ground from a cold water pipe or earth grounding rod directly to the FG
screw terminal on the DK40i power supply (see Figure 3-3).
DK40
KSU Mounting Considerations
i Installation
The Base KSU and the optional Expansion KSU are both designed to be mounted on a wall or
other vertical surface. Toshiba recommends using method 1 or 2 (see Figure 3-4).
Prior to Installation
1. Loosen the screws on the front cover and the side cover of the Base KSU, remove the covers
(see Figure 3-5). Figure 3-6 on Page 3-11 details the interior.
2. Place the BATT jumper plug to the On position.
3. Install a CO line board, either the TDDU or TCOU onto the TMAU board (see Figure 3-6).
The TCOU provides four loop start CO lines and can accommodate the Caller ID interface
unit.
The TDDU provides four DID lines.
4. Set CO line card switches.
TCOU: Set the TCOU PAD switches (SW400-SW475) to the appropriate position (see Figure
3-21 on Page 3-32). The factory setting is NORMAL. If CO lines are connected to a PBX or
are in close proximity to the central office the PAD position may be required.
TDDU: Set the TDDU PAD switches to the appropriate position. Also, set the high/low
voltage jumper plugs as required for proper dial pulse operation.
See Figure 3-22 on Page 3-34.
5. If you are not installing a TCIU2, skip to Step 6. To install the TCIU2 (see Figure 3-20 on
Page 3-29), align the prongs P20, P21, and P22 over P120, P121, and P122 of the TCOU and
gently press down. Slip the plastic stand-off hook through the hole.
CAUTION!
To prevent system malfunction, DO NOT install TCIU1 in the DK40i system.
Strata DK I&M 5/00

DK40i Installation
KSU Mounting Considerations
6. The TCOU or TDDU cards have a green and yellow wire with a two-prong spade on the end.
Slip the spade under the second screw from the right on the power supply (see Figure 3-6).
7. If applicable, install KSTU2 Standard Telephone Interface Unit. The KSTS2 comes pre-
installed onto the KSTU2. Then install both boards into the DK40i Base KSU (see Figures
3-17 ~3-19, beginning on Page 3-26).
8. If applicable, install the K5RCU or K5RCU2 or K4RCU3 (which provides Automatic Busy
Redial and DTMF tone detection) into the Base KSU (see "K4RCU, K5RCU or K5RCU2
Installation" on Page 3-23).
9. If applicable, install the KKYS (which provides built-in Auto Attendant) onto the K5RCU or
K5RCU2 or K4RCU3.
10. If applicable, install the TSIU Serial Interface PCB into the KSU (Figure 3-23 on Page 3-37).
If the TSIU is used for SMDR or TTY, then the PIOU/PIOUS SMDR/TTY output is not
active.
Testing the System's Power Supply
If the "AC" or "DC" LEDs fail to light in Steps 1 or 3, see TPSU16 Circuit Breaker Reset
Procedure on Page 7Case 1.
1. Plug the AC power cable into an outlet (see Figure 3-8). The "AC" LED on the power supply
lights green.
2. Turn On the DC power switch for the TPSU16 power supply (see Figure 3-6). The "DC" LED
on the power supply lights green.
3. Using a voltmeter or other device which checks voltage, measure the voltages referenced to
frame ground (FG) at the P16 connector pins (test points) located on the motherboard. The
voltages should fall within the ranges below.
Yellow-green, black, and green wires: 0V
Two yellow wires: -27V
Range: -25.94V~-28.66V
If the voltages do not fall within the ranges, unplug the DC power pins from the P16 connector
and measure again at the same location; if the ranges remain unacceptable. See TPSU16
Circuit Breaker Reset Procedure on Page 7Case 2.

Strata DK I&M 5/00

DK40i Installation
KSU Mounting Considerations
TPSU16 Circuit Breaker Reset Procedure
Case 1
If the AC and DC LEDs on the TPSU16 power supply in the Strata DK40i Base KSU do not light,
even though the AC power plug is inserted into the wall outlet and the TPSU16 DC power switch
is turned on, the AC overvoltage circuit breaker may have opened.
To reset the AC overvoltage circuit breaker
1. Remove the AC power plug from the wall outlet, turn the DC power switch Off, and wait six
minutes.
2. After six minutes, insert the AC plug back into the wall outlet and turn the DC power switch
On. The AC and DC LEDs should turn on and the system should operate.
If the system fails to operate, either the wall outlet is not providing AC power or the system's
power supply is defective.
3. If the AC power checks good, replace the power supply (see "Power Supply Removal and
Replacement" on Page 3-19).
Case 2
DK40
If the TPSU16 power supply AC and DC LEDs light, but the system does not operate, the TPSU16
i Installation
DC output overcurrent circuit breaker may have opened because of a DC short circuit.
To reset the DC output overcurrent circuit breaker
1. Turn the DC power switch Off for 15 seconds and then turn it back on. The system will go
back to normal operation if the overcurrent breaker resets.
2. If the system continues to fail, press in the two -24VDC circuit breakers located on the bottom
left corner of the TPSU16 power supply.
If, then, the system does not return to normal operation, the TPSU16 power supply may be
defective or an optional PCB may be shorting out the TPSU16.
3. Remove all optional PCBs and the Expansion KSU to locate the short, then repeat Steps 1 and
2 and perform the power supply test.
4. If the power supply fails the test, replace the power supply (see "Power Supply Removal and
Replacement" on Page 3-19 for more information.). If the power supply passes the test, the
DK40i Base KSU is probably defective.

surface.
4. Hang the unit from the top two screws and then secure the screws completely into the
mounting surface.
5. Finish securing the unit to the mounting surface by completely screwing the bottom two
screws into the wall.
6. Ground system according to "AC Power and Grounding Requirements" on Page 3-4.
7. Connect applicable wiring (e.g., modular CO line cords, 25-pair amphenol connector cable
see Figure 3-25 on Page 3-42) to the Base KSU and then fasten wiring to the unit with the tie
wrap that comes with the Base KSU (see Figure 3-8 on Page 3-13). Remove amphenol
connector clamp from plastic bag that comes with the Base KSU. Fasten the clamp to hold the
amphenol connector.
8. Connect Reserve batteries and plug battery cable into BATT connector of the KPSU16 power
supply (see "Reserve Power Option" on Page 3-17).
9. If the Expansion KSU is going to be installed, refer to "Mounting the Expansion KSU" on

Expansion KSU PCBs
A DK40i Expansion KSU from the factory does not come with any PCBs installed. (Table 2-5 on
Page 2-6 for a list of PCBs supported by the DK40i Expansion KSU and Chapter 9 Universal
Slot PCBs for detailed descriptions/installation instructions.) Toshiba recommends that PCBs
which support electronic, digital or wireless telephones be installed into slots 15 and 16 because
slots 17 and 18 cannot support speaker Off-hook Call Announce (OCA) or Data Interface Units
(DIUs) or more than 8 wireless handsets. See the section titled "Expansion KSU" on Page 2-6 for
configuration information for DK40i PCBs.
PCB Hardware/Software Options
PCBs can be configured for a variety of hardware and software options. Hardware options are
defined as either internal (generally related to optional PCB subassemblies) or external (related to
connection of peripheral equipment, such as background music, voice mail, etc.). Hardware and
software options for each PCB are identified in the individual PCB installation procedures in this
chapter.

DK40i Base KSU (mounts on TCOU)
Circuits per PCB: four caller ID circuits
Interfaces with:
caller ID
loop start CO lines
Older Version(s):
none
To receive Caller ID, a TCIU2 circuit must be available to each line. (See Figure 3-20.)
CAUTION!
To prevent system malfunction, do not install TCIU1 in the DK40i system.
Each TCIU2 Caller ID circuit has a two-wire tip/ring interface which must be bridge-wired across
its corresponding ground or loop start CO line tip/ring. This is done automatically by the PCB
connectors when the TCIU2 is mounted on the TCOU. However, if installing an RCOU/RCIU2 in
the Expansion KSU, the connection is made on the Main Distribution Frame (MDF). See the
RCIU wiring diagram in Chapter 10 Universal Slot PCB Wiring.
TCIU2 Installation
1. Turn power Off.
2. Install the TCIU2 onto the TCOU PCB by aligning the three sets of connectors marked TCOU
or TCIU2, depending on the card.
3. Press down evenly and firmly on the TCIU2 card.
TCIU2 Programming
Program 03: Automatically assigns TCIU2 (Caller ID circuit) to slot 14 (code 81) when the TCIU2
is installed and power is turned on.
Note
TCIU2 Caller ID circuits are numbered automatically in numerical order starting from
01~04 when the TCIU2 is installed. Slots with code 81 will increment the Caller ID circuit
numbers by four circuits on the DK40i.
Program *50: Assigns TCOU lines that will receive Caller ID to the associated TCIU2 Caller ID
circuit number. TCIU2 circuits 1~4 must be assigned to TCOU circuits 1~4, respectively. RCIU
circuits 5~8 should be assigned RCOU or RGLU circuits 5~8.
After assigning CO lines to Caller ID circuits, turn system power Off for approximately five
seconds and then back on or run Program 91-2 to activate Program *50 assignments.
Program *51: Sets the Caller ID (CLID)/Automatic Dialed Number Identification (ANI) memory
allocation for the appropriate stations. This memory is used to save CLID/ANI telephone numbers
for calls that are received but not answered (abandoned calls). CLID/ANI numbers are not saved in
station memory if they are answered. Stations can be allocated with memory to save up to 100
numbers in 10-number increments.
The total memory allocated to all stations in a system is 200 numbers.
Note
When a CO line rings multiple stations, a station must be the owner of the Caller ID or
ANI CO line to be able to save abandoned call (Caller ID and/or ANI) telephone numbers.
(See Program *52.)

Program *52: Assigns stations as owners of Caller ID CO lines. These stations will store the Caller
ID telephone numbers received on abandoned (not answered) calls for the lines which they own.
Typically all common CO lines are assigned to one designated telephone or attendant console and
private lines are assigned to individual private line telephones.
Note
A station must also be allocated with Caller ID/ANI storage memory in Program *51 to
store abandoned call telephone numbers.
Program 39, Code 462: Assigns the Caller ID/ANI Lost Call Auto Dial button to LCD telephones
that store Caller ID and/or ANI abandoned call telephone numbers. A user can scroll through the
stored abandoned call phone numbers and auto dial the selected number using this button.
Program 60-1, Key 01: Determines which information will be sent out the system SMDR port,
e.g., system Account Codes or CLID and/or ANI telephone numbers.
Turn LED 01 On if CLID and/or ANI information should be sent out the SMDR port.
Turn LED 01 Off if Account Codes information should be sent out the SMDR port.
Note
The system will initialize with LED 01 Off, e.g., Account Codes information will be sent
out the SMDR port.

The optional TCOU PCB installs onto the TMAU motherboard. (See Figure 3-21 and Table 3-7
for information on controls, indicators and connectors.)
Note
Only one TCOU or TDDU can be installed on the motherboard.
TCOU Hardware Options
The TCOU PCB accepts the optional Caller ID (TCIU2 not TCIU1) board. When the TCIU2 is
installed on the TCOU, the tip/ring of the TCOU circuits 1~4 are automatically connected to the
tip/ring of TCIU2 circuits 1~4 respectively.
TCOU Installation or Replacement
1. Make sure the power supply (TPSU16A) DC power switch is Off.
2. Mate the TCOU male connectors P110, P111, P112 to P10, P11 and P12 respectively on the
TMAU. Apply firm, even pressure to ensure proper connection. See Figure 3-6 for installation
information and Figure 3-27 on Page 3-44 for wiring.
3. Secure the three plastic stand-off tabs and install screws in upper right and lower left corners.
4. Set decibel (dB) PAD switches SW101, SW201, SW301, and SW401 to the appropriate
position. In most cases set to the normal position (NOR). Switches are factory set at the 0 (0
dB signal level drop) position. If CO lines are connected to a PBX or are in close proximity to
the central office, set the PAD positions to 3 to provide a -3 dB signal level drop between the
PBX and CO.
5. Slip the spade connected to the green/yellow wire under the second screw from the right on the
TPSU power supply (see Figure 3-21). Tighten the screw until the spade is snugly secured.
TCOU Removal
If you need to remove/replace the TCOU, make sure the power supply (TPSU16A) DC power
switch is turned Off.
To remove the TCOU
1. Loosen the screw on the TPSU power supply and free the spade.
2. Loosen and remove screws securing the TCOU to the TMAU (see Figure 3-21).
3. Pull back the three plastic stand-off tabs and pull up on the TCOU until P110, P111 and P112
are unplugged.

DK424 Configuration
4
This chapter explains how to configure the Strata DK424 system. The system has a modular
design which enables it to support a number of station and CO line configurations. The main
component of the system is the common control unit (RCTU) Printed Circuit Board (PCB).
The focus of this chapter is a series of worksheets, providing a systematic procedure for
determining the system's size. The worksheets also provide space to record the hardware and
station devices that make up the system. Tables and example worksheets are included to assist you
in filling out the worksheets.
Important!
Prior to Release 4.0, Tie and DID lines used station ports. With Release 4.0 and
higher processors, these lines do not use station ports, allowing larger capacity
systems when Tie and DID lines are required.
System Configuration
DK424 Configur
Important!
System Configuration can be complex and time consuming. For best results:
Use DKQuote to provide easy, fast, automated configuration. See the DKQuote User Guide
for more information.
ation
If you do not have DKQuote, use the Worksheets in this chapter.
The DK424's main components are: the DK424 Base Cabinet (DKSUB424), DK424 Expansion
Cabinets (DKSUE424), and four system processors (RCTUA4, RCTUBA3/BB4, RCTUC3/D4,
and RCTUE3/F4). The processor used in the system depends on the features and number of
telephones and CO lines required. Each cabinet is shipped with its required Power Supply
(RPSU280); the same power supply used in DK280 cabinets.
See Chapter 4 DK424 Configuration for detailed information on installing RCTU PCBs.

DK424 Configuration
System Configuration
Base Cabinet
The DK424 Base Cabinet provides two designated slots for the RCTU processor and six universal
slots for station, line, and feature PCBs. It provides six connectors for expanding the system to a
maximum of six Expansion Cabinets. It comes with a Motherboard Jumper Unit (MBJU) installed
between the R11 and RCTU slot on the front side of the backplane motherboard. The MBJU is
removed only when RCTUE/F is installed. MBJU is installed for all other DK Release 1~4 RCTU
processor PCBs.
Expansion Cabinets
Cabinet and Universal Slot Capacity: Up to six DK424 Expansion Cabinets can be connected to a
DK424 Base Cabinet. The number of DK424 Expansion Cabinets allowed depends on which
processor is installed in the DK424 Base Cabinet.
The DK424 Expansion Cabinets support either six or eight universal slots, depending on which
processor is installed in the DK424 Base Cabinet.
All Expansion Cabinets are six slot cabinets except DK424 Expansion Cabinets. DK424
Expansion Cabinets provide eight slots, but only when connected to a DK424 Base Cabinet
controlled by an RCTUE3/F3 processor with the MBJU removed.
No DK424 Expansion Cabinets are allowed when connected to the DK424 Base Cabinet with
an RCTUA processor installed.
One DK424 Expansion Cabinet provides six universal slots when connected to the DK424
Base Cabinet with an RCTUBA/BB processor installed.
Up to five DK424 Expansion Cabinets provide six universal slots each, when connected to the
DK424 Base Cabinet with an RCTUC/D processor installed.
Up to six DK424 Expansion Cabinets provide eight universal slots each, when connected to a
DK424 Base Cabinet with an RCTUE/F processor installed.
Table 4-1 shows DK424 cabinet and slot capacities for Release 3 and 4 processors.

DK424 and DK280 Compatibility
DK424 cabinets replace DK280 cabinets in the DK product line structure. DK424 Expansion
Cabinets began shipping in June 1995 and DK424 Base Cabinets in February 1997. All old DK280
Release 1~3 processors and DK280 Base/Expansion Cabinets can be mixed with new DK424 Base
and Expansion Cabinets with the following criteria (see Tables 4-2 and 4-3):

DK424 and DK280 Cabinets can be mixed in any combination, with one exception. If seven
cabinets are required, an RCTUE/F processor must be installed in a DK424 Base Cabinet and
the sixth Expansion Cabinet must be a DK424. In this case DK280 Expansion Cabinets
provide six universal slots and DK424 Expansion Cabinets provide eight universal slots.
DK280 and DK424 Base Cabinets provide six universal slots maximum in any configuration
and any RCTU processor can be installed.
DK280 Expansion Cabinets provide six universal slots maximum in any configuration.
DK424 Expansion Cabinets provide six universal slots maximum in any configuration with a
DK280 Base Cabinet, including a DK280 Base Cabinet with an RCTUE/F processor.

DK424 Configuration
System Configuration
DK424 Expansion Cabinets provide eight universal slots in one configuration only: when
connected to a DK424 Base Cabinet controlled by an RCTUE/F processor (MBJU jumper
must be removed - see installation for details). DK424 cabinets provide six universal slots in
all other configurations.
An RCTUE/F processor can be installed in a DK280 Base Cabinet. When an RCTUE/F
processor is installed in a DK280 Base, only five Expansion Cabinets (DK424 and/or DK280)
can be installed. These Expansion Cabinets provide only six universal slots.
All older DK280 Release 1~3 processors will function in the DK424 Base Cabinet. The
features available depend on the respective release and type of the RCTU. These processors
include RCTUA1, RCTUA3, RCTUB1, RCTUB2, RCTUBA3/BB3, RCTUC1/D2 and
RCTUC3/D3.
When an older processor is installed in the DK424 Base Cabinet, the DK424 and DK280
Expansion Cabinets provide six universal slots and the MBJU jumper must be installed -
see RCTU installation for details.
RCTUA in a DK424 Base allows no Expansion Cabinets.
RCTUB or RCTUBA/BB in a DK424 Base allows one DK424 or DK280 Expansion
Cabinet with six universal slots.
RCTUC/D in a DK424 Base allows up to five DK424 and DK280 Expansion Cabinets in
any combination. These Expansion Cabinets provide six universal slots.
Designated Speaker OCA, DIU Data, and T1 slots
DK424 systems require that PDKU2 PCBs that support Speaker Off-Hook-Call-Announce (OCA)
and PDIU-DS and RPCI-DI PCBs for data applications must be placed in the slots designated in
Tables 4-4 and 4-5.
Note
PDKU2s that support Handset OCA and RPCI TAPI-only can operate in any slot.
Additionally, to enable T1/DS-1 interface, the RDTU PCB(s) must be placed in certain slots, with
corresponding slots left vacant. (The operation of certain channels necessitates vacant slots.)
RDTU PCBs can be placed in the slots in bold type; the vacant slots are not in bold in the
following tables.
Example: for cabinet 1, if an RDTU is placed in slot 13 and you want to use RDTU channels
17~24, then slot 14 must be left vacant. If you installed a second RDTU, it would go into slot 15;
slot 16 must also be vacant if you want to use RDTU channels 17~24.

1. ISDN BRI TE-1 and TA include ISDN telephones, modems, video conference interfaces, etc. Up to two stations (TE-1 and/or
TA) can connect to and share one BRI S-type circuit. Only one station can connect to a BRI U-type circuit.
2. Speaker OCA, PDIU and RPCI capacity is determined by 2B channel slot availability and power supply limits.
3. To install the maximum of 28 total DKTs and EKTs in the DK40i, up to 16 of the stations can be EKTs and at least 8 of the
stations must be DKTs.
4. Maximum capacity of DKT/EKT stations per DK424 cabinet is 62, less for EKT 2000, 3000 (Power Factor limitation).

Features Capacities
System Capacity
The number of CO lines and stations needed determine the size of the system. Tables 4-9 and 4-12
show the station and line capacities for eight-port RCOU/RCOS CO line PCBs.
There is a trade-off between stations and lines. Every group of eight stations installed decreases the
CO line capacity of the system by eight, and vice versa. The exact hardware requirements depend
on the features required.
Tables 4-9~4-12 assume one cabinet slot is used for an Optional Interface PCB.

Telephones
Telephones
The DK424 system supports Toshiba Proprietary Digital (DKT) and older series Electronic
Telephones (EKTs). Standard telephones (500 or 2500 series) and devices that require a standard
telephone line interface (fax, modem, VM, etc.) can also be connected to DK424.
Toshiba provides the following 2000-series Digital Telephones for Strata DK424 systems.
DKT-2020SD20-button speakerphone with LCD
DKT-2010SD10-button speakerphone with LCD
DKT-2020S20-button speakerphone
DKT-2010S10-button speakerphone
Toshiba telephones can be equipped with optional subassemblies (listed on Page 4-33).
Attendant Position Options
The DK424 provides three options for attendant positions which answer system incoming calls.
See Table 4-9 for the number of options per RCTU processor. See Table 4-20 for configuration
considerations.
PC Attendant Consoleused for medium-to-heavy traffic systems where an attendant must
answer and transfer incoming calls. The PC Attendant Console requires a customer-provided
PC plus the RATU PCB.
Up to two consoles can be connected on systems with RCTUB or RCTUBA/BB or four with
RCTUC/D (Release 2 and 3) and RCTUE/F PCBs. The RATU PCB uses four station ports in
system software. RCTUC/D Release 1 and all RCTUAs do not support the attendant console.
DK424 Configur
Direct Station Select (DSS) Consoleused for medium traffic systems where an attendant
must answer and transfer incoming calls. The DSS console must connect to circuit 8 on a
PDKU PCB.
Digital Add-On-Module (DADM)used for medium traffic, smaller systems, where an
at
Attendant must answer and transfer incoming calls. The ADM connects to any 2000-series
ion
digital telephone. The DADM shares the associated telephones circuit so it does not require a
designated PCB or circuit port (see "DADM" on Page 4-33.)

Worksheet 1 System PCB (Slot) Requirements
Station PCBs/Slots Required
1.
Total digital ports divided by 8 (round up) =
Total PDKU2 PCB slots required
Notes
PDKU2 provides eight digital telephone ports (circuits). Circuit 5 (when associated with ports
004, 012, 020, and 028) can only interface with a DDCB. Circuit 8 can only interface with a
DDSS console (see Page 4-18).
The PDKU1 can also be used. The PDKU1 can only support Data Interface Units (DIUs) on
circuits 1~7, while the PDKU2 can support DIUs on all eight circuits. See Table 4-20 (example)
for slot limitations.
2. Total standard ports divided by 8 (round up) =
Total RSTU2 PCB slots required
Notes
The PSTU2 or PSTU1 can also be used. These earlier version PCBs can interface with the
same devices that the RSTU can, but they have different ring generators and cannot support
MW. See the RSTU/PSTU section in Chapter 9 Universal Slot PCBs for more details.
The RSTU2 provides eight standard telephone ports (circuits). Circuit 2 only can connect to a
separate Background Music (BGM) source. The RSTU can be equipped with an R48S to
extend the loop length of the RSTU from 600 ohms to 1200 ohms (see Table 4-17).
RSTU2 is required to operate message waiting lamps on a standard telephone.

Worksheet 3 System PCB Assignment Guide
Remote Cabinet Configuration Guidelines
Several new items must be considered when configuring a system with Remote Cabinets.
1. Each location must be configured independently. Break down the line, trunk and service
circuits by locations and use the rules provided elsewhere in this chapter to determine the
required quantities of cards.
2. Estimate the number of cabinets according to normal configuration rules.
3. Account for RRCU1A cards at each remote location. An RRCU1A card can support up to two
Expansion Cabinets at one remote location. For example, 20 PCBs at one location would
require three Expansion Cabinets and two RRCU1A cards. See Figure 5-39 on Page 5-60.
4. If necessary, adjust the number of cabinets required. The maximum number of Expansion
Cabinets per system is six. The maximum number of locations is five. In a maximum
configuration, at least one location will have two Expansion Cabinets.
5. Calculate the total number of RRCU1A cards required at all remote locations. Add the same
number of RRCU1A cards to the configuration of the base cabinet. If necessary, add a cabinet
at the base location to hold the cards displaced by the RRCU1As in the base cabinet.
6. Check the validity of the configuration. A valid configuration will generate positive answers to
the following questions.
Do all cabinets (local and remote) comply with power limitations? The RRCU1A has a
power factor of 4.5.
Are there six or fewer remote locations?
Are there five or fewer RRCU1A cards in the base cabinet?
7. Order one RDCL Data Cable Kit for each RRCU PCB. The kit includes one replacement door,
one cable bracket and two data cables.
8. Order one cabinet cover for each remote location.
9. Digital Trunks. A Remote Cabinet will support all PCBs that may be installed in a local
Expansion Cabinet, including digital trunk cards. However, the system cannot derive network
clock synchronization from a digital trunk installed in a remote cabinet. This requires a digital
trunk installed in the Base Cabinet or in a local Expansion Cabinet connected to the base by a
standard ribbon cable.

Worksheet 5 System Power Factor Check
The Strata DK power supply was engineered for maximum cost efficiency to provide power for
the most configurations. Because of this design, some power limitations exist when using old
electronic-type telephones and/or telephone option hardware.
For example, only 24 3000-series telephones can be installed in a cabinet. Each telephone and
PCB has a negative Power Factor (PF) and the RPSU424 or RPSU280 power supply have a
positive PF (+65). The sum of the telephones' PFs and PCBs connected to a signal cabinet must
not exceed 65. In the case of +5VDC, the power factor must not exceed 25.
The sum of the calculated cabinet PFs must not exceed the values provided on Page 4-38. Table
4-23 shows the PF for PCBs and the RPSU280. PF numbers for telephones and devices are shown
on the following page.

This chapter explains how to install the Strata DK424 system. It includes information on site
requirements and provides installation instructions for various cabinet configurations. It also
explains how to install ground wiring, AC power cabling, reserve power (Battery Backup) cabling,
and Printed Circuit Board (PCB) cabling.
Inspection
When the system is received, examine all packages carefully and note any visible damage. If any
damage is found, do not open the packages. Contact the delivery carrier immediately and make the
proper claims.
After unpacking (and before installing), check the system against the packing list and inspect all
equipment for damage. If equipment is missing or damaged, contact your supplier immediately.
Be sure to retain original packaging materials for re-use when storing or transporting system
hardware.
Packaging and Storage
CAUTION!
When handling (installing, removing, examining) PCBs, do not touch the back
DK424 Installa
(soldered) side or edge connector. Always hold the PCB by its edges.
When packaging and storing the system, remove PCBs from the system cabinet (the power supply
may remain installed in the cabinet for storage and shipment). PCBs should be packaged in their
original antistatic bags for protection against electrostatic discharge. Be sure to package equipment
tion
in its original shipping containers.

DK424 Installation
Site Requirements
Site Requirements
Input Power
The DK424 requires an input power source of 115VAC ± 10VAC, 50/60 Hz, 17.5 amps. The
system requires one or two AC outlets that must be dedicated to system use, fused, and grounded.
DK424 expansion cabinets installed at remote locations require their own 115VAC + 10VAC, 50/
60 Hz power sources. Each Remote Expansion Cabinet requires 2.5 amps. The system or remote
cabinet installation requires one or two AC outlets that must be dedicated to system use, fused, and
grounded.
See "Power Supply Installation" on Page 5-8 for complete AC power cabling, ground wiring and
battery installation instructions for local and remote cabinets.
CAUTION!
To avoid accidental power turn-off, it is recommended that an On/Off wall
switch not be used on AC circuits dedicated for the use of DK424.
A reserve power source (two or four customer-supplied 12-volt batteries) may be connected to the
DK424 to serve as a backup in case of power failure.
Separate reserve power may be required for remote expansion cabinets.
Clearance and Location
The Base and optional Expansion Cabinets may be either floor or wall mounted. Figure 5-1 shows
the minimum clearance requirements. See "Wall Mounting" on Page 5-11 and "AC Power
Distribution for Six Cabinets" on Page 5-36 for details.
Notes
Floor mounting requires the following additional hardware:
RFIF floor mounting stands and brackets.
RCCB electrical conduit box, if three or more cabinets are installed.
Wall mounting may require a plywood (3/4 inch thick) backboard.
When selecting a location for the cabinets, the location must be:
Dry and clean
Well-ventilated
Well-illuminated
Easily accessible
The location must not be:
Subject to extreme heat or cold
Subject to corrosive fumes, dust, or other airborne contaminants
Subject to excessive vibration
Next to television, radio, office automation, or high frequency equipment
Optional customer-supplied reserve batteries require a well-ventilated location close (within nine
feet) to the DK424 cabinets.

1. Only PESU circuits 1 and 2, and RDSU circuits 1~4 provide Off-premises Station (OPS) capability. PESU must use OL13A or
equivalent line conditioning for OPS connection. RDSU must use OL13A or OL13B if providing 24 volt loop voltage. If
equipped with the 48 volt loop option PCB (R48S), OL13A, OL13B, or OL13C may be used for OPS connection.
2. When ordering DS-1/T1 circuits, six items must be specified:
The number of channels per T1 circuit, fractional increments are normally 8, 12, or 16 channels, full service is 24 channels.
Unused channels must be bit-stuffed.
Type of CO line assigned to each channel: Loop Start, Ground Start, Tie (Wink or Immediate Start), DID (Wink or Immediate).
Frame Format Type: Super Frame (SF) or Extended Super Frame (ESF). The T1 provider normally specifies the Frame Format
to be used, either is adequate for DK424 CO digital voice lines. ESF provides a higher level of performance monitoring, but
requires trained personnel and the ESF CSU normally costs more than an SF only CSU.
Line Code Type: Alternate Mark Inversion (AMI) or Bipolar 8 Zero Substitution (B8ZS). The T1 provider normally specified
the Line Code to be used, either is adequate for DK424 T1 CO digital voice lines.
The customer may have to provide the Channel Service Unit (CSU) to interface the DK424 T1 circuit to the Telco T1 circuit.
(CSUs are a Telco requirement.)
RDTU Network Channel Interface Codes: 04DU9-BN, 04DU9-DNZZ, 04DU9-1SN, 04DU9-1KN, 04DU9-1ZN.
3. For information on how to order ISDN PRI/BRI circuits, you should refer to the Toshiba ISDN Training CBT. ISDN circuits
may require a customer-provided CSU for PRI and/or Terminal Adapter or Network Terminal units for BRI. In U.S. CSU/TAs
must be UL-listed in the U.S. In Canada, they must be CSA certified.
Note
Digital trunks (RDTU, RPTU) may be installed in a Remote Expansion Cabinet; however,
the system can only derive Network Clock Synchronization from digital trunks installed in
a Base Cabinet.

Cabinet Installation Considerations
Cabinet Installation Considerations
The Base (DKSUB424) and Expansion Cabinets (DKSUE424) can be wall or floor mounted. To
make it easier to add cabinets (after the initial installation) when a customer needs to expand,
install the Base Cabinet on top for wall-mount installations and on the bottom for floor-mount
installations.
The dimensions of the Base and Expansion Cabinets are:
Height:
Base Cabinet: 11 3/4 inches
Height:
Expansion Cabinet/Remote Expansion Cabinet: 10 inches
Width:
23 5/8 inches
Depth:
9 3/4 inches
Weight:
approx. 30.5 lbs. (14 kg.)
Note
The weight approximates a cabinet completely filled with PCBs. Weight may vary
slightly, depending on PCBs.

DK424 Installation
Power Supply Installation
Power Supply Installation
The Base and Expansion Cabinets are shipped from the factory without the power supply installed.
The DK424 cabinets use the same power supply (RPSU280 and/or RPSU424) as the DK280.
Note
RPSU280 and RPSU424 are fit, form, and functionally the same. They can be
interchanged and mixed in DK280 and DK424 systems.
To install power supplies in cabinets of new or installed systems
1. Remove the power supply from its box. The box should also contain a plastic bag with two
jumper plugs for the power supply DKSUB or DKSUE connector. An AC power cord and the
power supply mounting screws are provided with the KSU cabinet.
2. Make sure that the front and right side covers are removed from the cabinet (see Figure 5-2).
3. Slide the power supply into the right side of the cabinet so that its four mounting holes align
with the four cabinet mounting holes (see Figure 5-3). (Make sure that the two backplane FG
wires are positioned between the FG wire holder and the power supply.)
Note
The backplane FG wires are not safety grounds: they are required for proper system CO
line operation.
4. Plug the DC OUT cable plug into the DC OUT connector on the power supply. (The plug has
a guide key on it to ensure that it is plugged in correctly.)
5. Secure the FG wire spade lug to the power supply with the FG screw.
6. Secure the power supply to the cabinet with the four provided screws.
7. If the cabinet is the Base Unit, a standalone Remote Expansion Cabinet, or the first in a stack
of Remote Expansion Cabinets, plug the Base Jumper Plug into the "DKSUB" jumper
connector on the power supply (see Figure 5-3).
8. If the cabinet is an Expansion Unit (DKSUE), plug the jumper plug that does not have a wire
connected into the "DKSUE" jumper connector.
Important!
The power supply with the "DKSUB" jumper plug (plug with wire) installed is the
master and has On/Off control over all other power supplies, which are designated
as slaves. If the master power supply is turned Off or On, all other power supplies
will automatically turn Off or On. (Individual power supplies must be turned On.)
Power supplies that have the "DKSUE" jumper plugs (plug without wire) installed
will not control other power supplies, but can be turned Off or On individually with
their own On/Off switch. (The master power supply must be on and the intercabinet
"Data" ribbon cable must be installed to allow a slave power supply to be turned
On.)
9. See Figure 5-3 to ensure that the power supply is properly installed.
10. Install power supplies in all cabinets, using Steps 1~9.
11. Install the Base and optional Expansion Cabinets, ground wiring, AC and reserve power
cabling, and PCB cabling per the "Recommended Installation Sequence" on Page 5-7.
Note
Power Supply testing procedures are provided in the Fault Finding chapter, which should
be referred to if it is suspected that the power supply does not work properly.

Power Supply (RPSU280 or RPSU424) Removal
1. Remove the front and right side covers (Figures 5-2 and 5-3) from the cabinet where the power
supply will be removed. Remove the right side covers of other cabinets as necessary to
disconnect wiring.
2. Turn the power supply Off, and disconnect the AC power cord, all ground wiring and reserve
power cabling that is connected to the power supply.
3. Disconnect the DC OUT cable plug from the DC OUT connector.
4. Loosen the four mounting screws securing the power supply to the cabinet and remove the
power supply.
Power Supply Replacement
Install the replacement power supply per "Power Supply Installation" on Page 5-8.
Wall Mounting
If the cabinet mounting holes align with wall studs, the cabinet can be installed directly on the wall
(see Figure 5-4). For more than two cabinets, a wooden backboard between the cabinet and the
wall is highly recommended (see Figure 5-5).
Base Cabinet (DKSUB424) or First Remote Expansion Cabinet Installation
1. If using a backboard: Obtain a board, such as plywood, that is at least 3/4 of an inch thick. The
board should be at least 6-1/2 feet high (completely expanded systems with seven cabinets
require this much height) and two feet wide (minimum).
Secure the board to the wall with wood screws with the bottom edge of the board is six inches
above the floor. (If there are wall studs, make sure the screws align with the studs.)
2. Remove the front, back, and side covers from the Base Cabinet or first Remote Expansion
Cabinet (see Figure 5-6).
Note
The bottom left screw must be completely removed. The two screws on each side cover
and the three screws on the front cover should only be loosened and the covers slid to the
right for removal.
DK424 Installa
3. Hold the Base Cabinet back cover against the wall or backboard so that its two top mounting
holes are approximately 6-1/2 feet (78 inches) above the floor. This allows seven cabinets to
be installed (top-down) with a six-inch clearance between the floor and bottom cabinet (see
Figures 5-7 and 5-8).
tion
4. Use a level to make sure that the back cover is held level.
5. Trace the upper arch of the top mounting holes with a pencil.
6. Remove the back cover from the wall.
7. Draw a line between the top two marking hole marks.
8. Drill holes on the line in the middle of the arch tracing.
9. Screw #12 X 1.25 inch size wood screws into the two drilled holes, leaving about 1/8 of an
inch clearance between the screw heads and the wall.

AC Power and Grounding Requirements
AC Power and Third Wire Ground Test
Test each "third wire ground" separately for continuity by either measuring the resistance between
the third prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm) or by using
a commercially available earth ground indicator. If neither procedure is possible, perform the
following procedure.
To test each "third wire ground" for continuity
WARNING!
Hazardous voltages that may cause death or injury are exposed during the
following test. Use great care when working with AC power line voltage.
1. Obtain suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires)
on the wall outlet. The reading obtained should be between 100~125VAC.
3. Move one of the meter probes to the third terminal (green wire ground, point A in Figures 5-21
and 5-22). Either the same reading or a reading of zero volts should be obtained.
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe
to the second voltage terminal.
CAUTION!
If a reading of zero volts is obtained on both voltage terminals (white wire to
green wire, black wire to green wire), the outlet is not properly grounded. Omit
Steps 5 and 6, and proceed directly to Step 7.
5. If a reading of zero volts on one terminal and a reading of 100~125VAC on the other terminal
is obtained, remove both probes from the outlet.
6. Set the meter to the "OHMS/Rx1" scale. Place one probe on the ground terminal, and the other
probe on the terminal that produced a reading of zero volts. The reading should be less than
one ohm.
CAUTION!
If the reading is more than one ohm, then the outlet is not adequately grounded.
If the above tests show the outlet AC voltage is not in range or is not properly
grounded, the condition should be corrected (per Article 250 of the National
DK424 Installa
Electrical Code) by a qualified electrician before the system is connected.

WARNING!
Hazardous voltages that may cause death or injury are exposed during the
following test. Use great care when working with AC power line voltage.
1. Disconnect the AC plug(s) of the system to make sure that the separate earth ground paths are
separated.
2. With a suitable volt/ohm meter, perform a reading between points "A" and "B" shown in
Figures 5-21, 5-22 and 5-28. Verify that the readings do not exceed the figures listed below. If
they do, the condition must be corrected by a qualified electrician before the system is
connected.

AC Power Cabling Installation
Intercabinet Ground
Connect intercabinet ground wires (supplied with each cabinet) between cabinets in systems with
two or more cabinets (Figures 5-21 and 5-22).
AC Power Cabling Installation
The system requires an input power source of 50/60 cycles, 115VAC ± 10VAC, and up to 17.5
amps AC to operate. AC power cabling requirements vary, depending on the method of cabinet
installation and the number of cabinets. Refer "Summary of Electrical/Environmental
Characteristics" on Page 5-4 for electrical power requirements.
Some floor-mounted configurations and all wall-mounted configurations require AC outlets,
which must be dedicated to system use, fused, and grounded. To avoid accidental turn off, do not
configure the outlet with an On/Off switch.
AC Power for One or Two Cabinets (Wall Mount)
Refer to the following instructions to install AC power cabling to floor or wall-mounted systems
with just one or two cabinets:
1. Make sure all power supply (RPSU280) switches are in the Off position.
2. If two cabinets are installed and local electrical code allows only one AC power cord from the
system, install the RPSB2 in the bottom cabinet per Figures 5-19 and 5-20.
3. For AC power cords that will be plugged directly into a wall outlet: Undo the tie wrap that
keeps the cord coiled. Plug female end of the cord into the power supply, and plug the male
end into the wall outlet.
4. For AC power cords that will be plugged into power strips: Do not undo the tie wrap that
keeps the cord coiled. Plug female end of the cord into the power supply, and plug the male
end into the RPSB power strip. Plug the power strip power cord into a wall outlet (see Figure
5-9).
Note
Power Supply testing procedures are provided in Chapter 14 Fault Finding, which
should be referred to if it is suspected that the power supply does not work properly.

AC Power for Three or More Cabinets (Wall Mount)
Local electrical codes specify that a maximum of one or two AC power cords from the system can
be plugged into wall outlets. Systems with three or more cabinets must be equipped with power
strips (RPSB1 or RPSB2) to adhere to this requirement. Each power strip has three outlets and an
AC power cord.
Three- or four-cabinet systems require one power strip, while five- to seven-cabinet systems
require two or three power strips, depending on local electrical code requirements pertaining to the
number of AC power cords (one or two) allowed from the system.
