Trunking System
• Briefly note the device type (keypanel, TIF, program source, CDP-950, etc.). Other useful information might
include the device location and usage, as well as any labeling on the intercom cable.
• Write down a name of up to eight characters in the “Alpha” column of the worksheet. You will enter this
name inot the intercom system later using AZedit. Then, whenever you assign the port to an intercom key,
the name will appear in the keypanel display for that key.
• If the intercom system uses optional trunking (where two or more intercom system are interconnected and
users can intercommunicate using special equipment) you may wire a second name in the “Alias” column of
the work sheet, if desired. An alias may be useful, for example, to prevent confusion when the same alpha
name is already being used by two intercom ports located in separate intercom systems. When one of these
ports in one intercom system is assigned to a keypanel key in the other intercom system, the alias name, and
not the alpha name will appear in the display.
NOTE: In AZedit, you can enter Alias names at the same time as you enter Alpha names. If you do not enter an Alias name,
AZedit will automatically use the Alpha name as the default.
By default, AZedit is not configured for turnking operation. If you want to enter Alias names and use trunking with AZedit,
you must enable trunking.
WARNING: Enabling trunking will erase the system setup and erase all data. SAVE your file set before enabling trunking.
To enable trunking, do the following:
a.From the Options menu, select Preferences, and then Advanced page.
b. On the Advanced page, select Enable Trunking Support.
Once you have made this change, you will be able to enter alias names in AZedit.
3. Connect devices to the intercom ports as noted in the worksheet. For each type of device, refer to any installation notes
included on the following pages. Or, refer to the installation information supplied with the device. The ADAM CS frame
with a 50-pin Telco back panel can be connected to any of the folliwng breakout formats:
punch blocks
jack fields
XCP-954-618
XCP-955
4. Using AZedit, enter the Alpha and Alias names that you recorded in your worksheets. Click the “Port Alpha” button on the
toolbar, then press the F1 key on the computer to get help, if necessary.
5. Complete the intercom system configuration, as described in the AZedit software help, under “General Procedure to
Configure the Intercom System”.
Trunking System
General Theory of Operation
In a trunking system, the audio lines (not data) of one or more intercom ports are interconnected between two separate
intercom systems. The system administrator in each intercom system then places restrictions on these ports to prohibit them
from being assigned to any keys. This reserves the port for exclusive use as trunking lines. A special data link is also connected
from each intercom system to the trunking system for exchange of system control signals. Once the interconnections are
completed, the tunking system is programmed in TrunkEdit.
After the trunking system has been programmed, system administrators or keypanel users in each intercom system may
request lists of persons, party lines, etc. from the other intercom systems for purposes of key assignment just as they would in
their own intercom system. After keys are assigned, keypanel operators can activate them to talk or listen, just like in their own
