SITE PREPARATION AND MDF/IDF CONSTRUCTION
Preinstallation planning is essential. Advanced planning minimizes installation time,
cost, and disruption of the customer business activities.
2.1
Precautionary Information
Observe the following warnings during installation.
1.
Never install telephone wiring during a lightning storm.
2.
Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
3.
Never touch uninsulated telephone wires or terminals unless the
telephone line is disconnected at the network interface.
4.
Use caution when installing or modifying telephone lines.
2.2
Surveying the Customer Site
In most cases, a survey of the customer site is necessary to determine the
proper placement of the Main Distribution Frame (MDF), the exact dimensions
of the area selected for the MDF, cabling requirements, and possible
Intermediate Distribution Frame (IDF) locations.
The information obtained at the customer site can permit the installer to
partially assemble the MDF before installation at the customer premise. This
can reduce the time spent installing at the customer site and reduce
downtime.

Selecting the Best Location for Proper Installation
2.3.1
Selecting the KSU Installation Site
When selecting an installation site for the KSU, consider the
following conditions to ensure proper installation.
r
KSUs are normally wall mounted to protect against accident or
flooding.
r
The KSU should not be located directly beneath pipes. Leaks
or condensation could damage the Electra Elite IPK II system
equipment.
r
The area where the KSU is located must be free of corrosive
and inflammable gases, excessive chemical or industrial dusts,
and other materials that could cause a hazard to personnel or
to the proper functioning of the equipment.
r
The operating ambient temperature and humidity must be
within the limits specified in 5.2.2 Environmental Conditions in
Chapter 3 System Specifications.
r
The operation of the system is virtually noiseless and allows
wide selection of installation sites. Take care to ensure the
KSUs do not present a hazard to office traffic. To minimize
cabling costs, a centralized location must be chosen.
r
Locate the KSU at a site where a dedicated AC power source
can be easily accessed.
r
Connect the KSU to a dedicated AC receptacle that is not
being used for any other device such as a computer, copier, or
facsimile machine.
2.3.2
Selecting a Permanent MDF Location
When selecting a permanent site for the MDF, the technician may
encounter some of the following conditions.
r
Limited space is available but must be used.
r
The available space may pose one or more environmental
hazards.
r
The proposed location has limitations such as insufficient
lighting or the lack of a suitable ground for the KSUs.
r
The technician that encounters these conditions must provide
the best possible solution for installing the equipment. This
document cannot cover all possible situations, precautions,
and actions.

2.3.3
Selecting a Site for Installing the Telephones
When a site is being selected for telephone installation, consider the
following conditions to ensure proper installation.
r
Ensure that the cable length and line resistance (loop),
between the KSU and the telephones, comply with the
specifications listed in Table 3-6 Dterm Series i or Dterm IP
Terminal Loop Resistance and Cable Length on page 3-22 and
Table 3-7 Electra Elite/Dterm Series E Multiline Terminal Loop
Resistance and Cable Length on page 3-23.
r
Select a place where devices that require an external power
supply can be easily connected to an AC outlet.
2.4
Constructing the Main Distribution Frame (MDF)
The Main Distribution Frame (MDF) has two different standard quick-connect
terminal blocks that are mounted on a 3/4" plywood backboard. Mounting
these blocks on standoffs for ease of access is recommended. The
recommended blocks are 66B50 for termination of the MDF Cable Assembly
and 66M50 for termination of the station cables.
The Intermediate Distribution Frame (IDF) requires the 66M50 blocks only.
Both the MDF and the IDF use standard bridging clips for each terminal block.
The bridging clips mate the left half of the terminal block (terminated cable
run) to the right half of the terminal block (crossconnection wire) to the
terminal block (crossconnection wire). The bridging clips are also useful during
troubleshooting to help isolate the cable runs and terminals/telephones from
the central equipment and the Central Office Network from the system. Refer
to Figure 5-1 Typical Full MDF Layout.

Handle the drive and DSP carefully! Do not drop the
drive or apply pressure to it. Do not touch the printed
circuit board unnecessarily. Doing so can make it
inoperable.
This unit makes extensive use of CMOS technology that is very
susceptible to static; therefore, extreme care must be taken to avoid
static discharge when handling.

A 4-port CTP( )-U10 ETU must be programmed as an 8-port
CTP( )-U10 ETU. Ports 5~8 should not be assigned extension
numbers or included in the hunt group.

A 12-port CTP( )-U10 ETU must be programmed as a 16-port
CTP-U10 ETU. Ports 13~16 should not be assigned extension
numbers or included in the hunt group.

VMP( )-U40 ETU
7.11.1
Description
This ETU is a PC-platform that contains disk space for voice
recording storage and application software. It can be configured as
a 2-port, 4-port, or 8-port interface.
The 2- or 4-port interface includes one digital signal processor
(DSP); a DSP-U30 Unit must be installed for the 8-port interface.
Major features include:
r
A faster running 486-based processor allows quicker boot and
faster operation.
r
Cosession direct connection speed of 57,000 baud is
supported as the only direct connection speed for all U40
ETUs.
r
Port upgrades are performed by replacing the Compact Flash
drive with another drive with the needed port configuration.
r
All ETUs have a built-in modem for remote console
programming. An external modem and single-line port can
also be used for remote programming. The internal modem is
accessed from the automated attendant by dialing the modem
extension ID that is only an ID used by voice mail, not an
extension on the telephone system.
r
The voice mail application efficiently shuts down after active
calls are completed, and the ETU turns off when the shutdown
switch is placed in SHUTDOWN (Q51231 or higher database is
required).
r
The system manager can select a special language for a
particular subscriber at the console, and the subscriber hears
the language when login is complete. The default language
must be the system default language (Q51231 or higher
database is required).
r
A database entity, the Language Selection Box, allows outside
callers to choose a language. Each database entity (e.g.,
personal message box) also has the selected language
associated with it (Q51231 or higher database is required).
