The echo cancellation feature cancels echoes with delays up to 96 milliseconds. Echo cancellation is
disabled automatically when the circuit pack detects a 2100-hertz phase-reversed tone put out by high-
speed modems (56 kilobaud) but not when it detects a 2100-hertz straight tone generated by low-speed
modems (9.6 kilobaud).
For information on installing port circuit packs, refer to
information on setting the option switches, refer to the job aid titled
information on administering the circuit packs, refer to the Administrator's Guide for Avaya
Communication Manage.
Echo cancellation must first be purchased then activated by the license file. Refer to the Administrator's
