Module Information - AT&T MERLIN LEGEND Release 3.1 System Planning Manual

Selecting Line/Trunk Options
Test Telephone Number(s)
Timers and Counters
Terminal Equipment Identifier (TEI)
After completing the procedure for filling in the module information on Form 3b,
pages 1 and 2, continue to the next section to fill in PRI options.
NOTES:
1. The PRI service type must be selected before entering the PRI information
during system programming. For detailed information, see the Equipment
and Operations Reference.
2. Because of the complexity of the timer, counter, and terminal equipment
identifier information, the factory settings should rarely be changed. Incorrect
settings can have an adverse affect on the operation of PRI facilities.
3. If there is more than one 100D module set up for PRI service or you have
more than eight B-channel groups assigned to a module, make copies of
Form 3b (page 4) as necessary.

Module Information

Use the procedure in this section to fill in module information on pages 1 and 2
of Form 3b, Incoming Trunks: DS1 Connectivity (100D Module). Then proceed
to the next section, "PRI Options."
Planning Form Instructions
On Form 3b (page 1), Incoming Trunks: DS1 Connectivity (100D Module), for
each 100D module with PRI service:
1. In the module Slot No. space, write the number of the control unit slot that
contains the module (see the Control Unit Diagram on Form 1).
NOTE:
If more than one 100D module is used, complete the first box, Module 1,
to show the options assigned to the 100D module in the lowest-
numbered control unit slot. Use the second box for the second lowest-
numbered slot and the last box for the highest-numbered slot.
2. Under the Type of Service heading, check PRI. (During programming,
PRI must be selected here before the PRI options information is entered.
When it is selected, the system restarts.)
3. Under the Frame Format heading, change the factory setting by checking
the Extended Superframe (ESF) box.
4. Under the Suppression (Line Code) heading, change the factory setting
by checking the B8ZS box.
