Echo Cancellation

The TN464HP and TN2464CP 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 Upgrade Firmware on Programmable Circuit Packs on page 231.

The TN464HP and TN2464CP 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-reversedtone 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).
