SWITCH (OR CUSTOMER) REQUIREMENTS FOR DCP

MODE 3

Switch requirements depend on whether the systems are serving the same switch or are serving different
switches.

Colocated Requirements

One of the following switches must be used and equipped with a DCP interface for termination of the
AUDIX DCP channels:

System 75, Generic 1, Generic 2 (universal module), or Generic 3:

Two TN754 Digital Line ports are required per AUDIX system. Although not required, it is
recommended that the circuits be on separate packs so all four network channels will not be lost in the
event a single pack goes bad.

NOTE

All ports on a TN754 should be assigned as either lines (pdm) or trunks (tdm). Trunk
ports will have problems when assigned on circuit packs that have other ringing stations
(that is, line circuits). Make sure no ports on the pack is assigned as a trunk (TDM) or
assigned to a modem pool.
