This section provides information about the TN464GP and TN2464BP circuit packs with echo
cancellation and the procedure to
Administer TN464GP/TN2464BP
on page 599.
The TN464GP and TN2464BP circuit packs with echo cancellation are intended for DEFINITY
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, see
Upgrade Firmware on
Programmable Circuit Packs
on page 715.
The TN464GP and TN2464BP circuit packs are backwards compatible, although the echo cancellation
feature can be used only 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 (56 kbaud) but not when it detects a 2100-Hz straight tone generated by low-speed modems (9.6
kbaud).
For information on installing port circuit packs, see
Add Port Circuit Packs
on page 567. For information
on setting the option switches, see
Option Switch Settings
on page 741.
Echo cancellation must first be purchased, then added to the system via a new License File.
