Echo Cancellation

The MM710 Media Module features an integrated echo canceller. Echo cancellation supports channels
carrying voice and is not intended for channels that support data. The MM710 has the capability to detect
modem tone and turn off echo cancellation accordingly for the duration of a data call. Echo cancellation
on the MM710 is administrable per channel. The echo cancellation circuitry on a given MM710 is driven
by administrable parameters.
The MM710 Media Modules are intended for use with ATM, IP, wideband, or other complex services
which are likely to have problems with echo.
The echo cancellation circuitry on a given MM710 is a right-to-use feature activated on the System-
Parameters Customer-Options form. Also on this form is a field Maximum Number of DS1
Boards with Echo Cancellation that indicates the number of DS1 boards on which echo
cancellation is activated for a specific customer.
The DS1 MEDIA MODULE form for the MM710 Media Module has fields to support echo cancellation:
Echo Cancellation?, EC Direction, and EC Configuration. The Echo
Cancellation? field displays only if the Echo Cancellation feature has been activated on the
system-parameters customer-options form by entering a y in the DS1 Echo Cancellation?
field. The EC Direction and EC Configuration fields do not display unless the user has entered
y in the DS1 Echo Cancellation? field.
•
EC Direction determines the direction from which echo will be eliminated, ether inward or
outward.
•
EC Configuration is the set of parameters that will be used when cancelling echo. This
information is stored in firmware on the MG-DS1 Media Module.
