TR-LN-BD (Trunk Line Board)
S8700 | 8710 / S8500 / G700
The TN797 Analog Trunk and Line circuit pack provides 8 ports, any of which may be
administered as one of the following:
Note:
Note: G700: The separate, but equivalent, MG-ANA MO can reside in slots 1–4 of a
G700 media gateway. Refer to MG-ANA (ANALOG MM711)
on page 1583 for
information about this MO.
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 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.
For circuit pack problems, see XXX-BD (Common Port Circuit Pack/Media Module)

page 2539.
