3 Lines/Trunks
Selecting Line/Trunk 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,
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).
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.
5. Under the Signaling Mode heading, check Common-Channel Signaling
(CCS).
''PRI Options''.
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.
