Echo Cancellation
The TN464GP and TN2464BP circuit packs with echo cancellation are intended for customers who are
likely to encounter echo over circuits connected to the Direct Distance Dialing (DDD) network. These
circuit packs are intended for channels supporting voice; therefore, they support the following trunks:
CAS, CO, DID, DIOD, DMI, FX, Tie, WATS. They do not support any data trunk groups.
NOTE:
The P suffix designation means the circuit pack is programmable; new firmware can be
downloaded directly to the circuit pack. For more information refer to
on Programmable Circuit Packs
The TN464GP and TN2464BP circuit packs are backwards compatible, although the echo cancellation
feature can only be used with Release 1.1 or later of Avaya™ Communication Manager and after the
feature is enabled.
The echo cancellation feature cancels echoes with delays up to 96 ms. Echo cancellation is disabled
automatically when the circuit pack detects a 2100-Hz phase-reversed tone put out by high-speed
modems (56K baud) but not when it detects a 2100-Hz straight tone generated by low-speed modems
(9.6K baud).
For information on installing port circuit packs, refer to
on setting the option switches, refer to
information on administering the circuit packs, refer to the Administrator's Guide for Avaya
Communication Manager.
