Maintenance Object Repair Procedure

TR-LN-BD (Trunk Line Board)

The TN797 Analog Trunk and Line circuit pack provides 8 ports, any of which may

be administered as one of the following:

Table 8-509. TN797 Analog Trunk and Line circuit pack – port

Central Office trunk (CO)

CAMA/E911 trunk

Direct Inward Dialing

on-or-off premises

In the U.S., Canada, and like countries, every CO trunk port of TN797 Analog

Trunk and Line circuit packs should be administered as GS (ground-start) trunks

rather than as loop-start trunks, because GS signaling provides disconnect

supervision, and loop start does not. If for some reason, a port on the TN797

must be administered as loop start, it must be administered as 1-way only – either

incoming or outgoing – not only at the S8700 IP Connect switch, but also at the

CO switch. This is necessary to avoid collisions (i.e., "glare") and other highly

undesirable conditions.

The TN797 Analog Trunk and Line circuit pack does not support Neon Lamp MWI

(Message Waiting Indication). No maintenance of the terminal connected to the

Neon Analog Line circuit pack is performed.
