ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 1
7-121
Trunk Group/Trunk Group Members — DS1 Trunk Applications
For DS1/DMI applications the TN722_ circuit pack emulates three categories of trunk types, while
the TN767 circuit pack emulates three additional trunk types; refer to table 6-1, Supported Digital
Facilities.
DS1/DMI trunking applications are defined by using page 1 and page 2 of the
TRUNK GROUP screen;
this is the same as for analog trunk groups. Trunk members are added to the
GROUP MEMBER
ASSIGNMENTS
screen (pages 3 through 9). This series of screens administers many of the same
parameters as procedures 100 and 101 do for Generic 2. Figure 7-63, Trunk Group Screen, Page 1
(Tie), depicts this procedure.

Figure 7-63. Trunk Group Screen, Page 1 (Tie)
Most fields require no unusual entries for DS1 service applications. Only those fields that may
require special attention are mentioned.
The default is voice with avd and data being the alternate selections.
Comm Type
NOTE: Trunk groups that are administered avd require that the DS1
Interface also be administered for common-channel signaling (24th).
Furthermore, if avd is translated; then the baud rate, synchronization, and
duplex fields are displayed. These three fields enable the trunk group to
function with a modem pool. A "Data Originate code" is required to start a
modem pool call.
