Add TN464GP/TN2464BP with Echo Cancellation

Add TN464GP/TN2464BP with Echo
Cancellation
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.
The TN464GP and TN2464BP circuit packs are backwards compatible, although
the echo cancellation feature can only be used with Release 9 or later software
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, refer to Installing Port Circuit
Packs. For information on setting the option switches, refer to Option Switch
Settings. For information on administering the circuit packs, refer to the DEFINITY
ECS Release 10 Administrator's Guide.
Echo cancellation must first be purchased, then activated by someone with
customer options login privileges. Refer to the DEFINITY ECS Release 10
Administrator's Guide .
Use the following procedure to modify the settings:
NOTE:
You do not need to busyout the circuit packs to modify the settings. But the
modified settings do not take effect until either the port is busied out or the
scheduled maintenance runs.
