Paging Trunk Operation - Avaya Nortel Communication Server 1000 Reference

NT8D15 E and M Trunk card
The TRC and NTC COS options determine the operation of the switchable pads contained in
the trunk circuits. They are assigned as follows:
• TRC for a two-wire non-VNL trunk facility with a loss of greater than 2 dB or for which
impedance compensation is provided, or for a four-wire non-VNL facility.
• NTC for a two-wire non-VNL trunk facility with a loss of less than 2 dB or when impedance
compensation is not provided.

Paging trunk operation

When used in the paging mode, a trunk is connected to a customer-provided paging amplifier
system (not zone selectable). When the trunk is accessed by dial-up or attendant-key
operation, it provides a loop closure across control leads PG and A. See
