Special Conditions

If an external call is made using a PBX line, the call elapsed timer displays but does
not have any affect on the Automatic Redial condition.

If a disconnect or busy signal is detected by the system while on an analog external
line during Automatic Redial, the call is placed into wait mode (the time between redial
attempts).

When using an ISDN external line, a busy tone is not detected and the line is placed
into wait mode until release notification is received. Automatic Redial continues until
the programmed number of retries is exceeded.

If the user cancels Automatic Redial during wait mode, the external line is released
and the telephone returns to the idle condition (if the handset is in the cradle and the
speaker is off). If the handset is off of the cradle or the speaker is on, internal dialtone
is received.

After the number of redials has exceeded the programmed number of redial attempts,
the external line is released and automatic redialing ends.

GENERAL INFORMATION
Optional equipment is available to enhance the InfoSet 408 system. These adapters
can be purchased separately from the system and added as your business needs
grow. The adapters listed in this chapter can only be installed on the Electra Elite
telephones.
A telephone can have up to three adapters installed at the same time. If attaching an
APR-U Unit, a CTA-U Unit, or an HFU-U Unit, an external power supply is required.
Only one power supply is needed even if more than one adapter is installed.

The CTA-U Unit requires system software version 2.0.
When an adapter is installed for the first time into a telephone, the base cover on the
telephone may have to be modified. The base cover has two access panels that are
removed before the cover can be closed over the adapters to complete the
installation.

Telephone Programming

SECTION 1
INTRODUCTION
When the system is initially installed, it is fully operational with the preset default
settings. Users can customize the system by changing system programming values
using either telephone programming or PC programming. This chapter provides
detailed instructions for programming from a telephone.
Telephone programming is designed primarily for experienced users.
Therefore, if you are a first-time user, we strongly recommend that you use PC
programming instead of telephone programming.
It should be noted that only one telephone can be in programming mode at a time. If
another telephone user attempts to access programming mode, that telephone is
blocked from entering programming mode.
The following InfoSet and Electra Elite telephone types can be used as programming
telephones.

DTB-16D-1(BK)/(WH) TEL

DTU-16D-2(BK)/(WH) TEL

DTU-32D-2(BK)/(WH) TEL

Only telephone ports 1 and 2 (normally extensions 10 or 11) can be used to
enter telephone program mode.
S
ECTION 2
ENTERING PROGRAMMING MODE
Once you have entered into programming mode you can access the various
programming functions by either using the navigational keys or by manually entering
the function number (e.g., 001-1, 002, 220, etc.). The function number provides
access to the area you want to program. Table 6-1 Navigational Keys for Telephone
Programming provides a list of keys you can use to navigate the system. Table 6-2
Programming Functions Quick Reference Chart provides a complete list of all of the
programming functions.
To program the system using a telephone, you must first enter programming mode.

When function numbers are grouped (e.g., 001-1 ~ 001-9), all of the
function numbers are displayed at the same time. To change
between the default value and the alternate value, press the dial pad
key that corresponds to the last digit of the function number you are
changing.
For example:
When you access the function number for 001-1~001-9. The system
displays:

If you want to change the programming value for Function 001-4,
press on the dial pad. When " appears on the display, you
have changed to the alternate programming value for that function.
The default value is displayed if this is the first time you are using the
system. If the system has been previously programmed, the
alternate value may be displayed instead of the default value. It is
important to note that the series of numbers is displayed in
descending order (987654321).

The following navigational keys are used. Note that the Electra Elite

PROGRAMMING FUNCTIONS
The table provides a complete list of all of the programming functions. These are
listed in order by function number. The table consists of four columns, a brief
explanation of each column is listed below.

Function Number
Lists the number used by the system to access the programming functions.

Function Name/Telephone Display
Lists the function name and shows how the function appears in the display of
the telephone. Since there is limited space in the telephone display, the
functions are abbreviated and will not match the function name. To
distinguish the function name from the telephone display, the following font is
used to indicate the display: . The telephone display
typically consists of two lines. The first line is the abbreviation and the
second line is the default setting. If your system has been previously
programmed, the number on your display may be different from the one
provided in the table.
