ECHO CANCELLER (8 PORT CE-EC-128) clei The 8-port CE Echo Cancellation Module is an extension module for the 120 ohm 7470/7270/7670ESE 8-port T1/E1 CE Cards. The echo cancellation module monitors ingress and egress speech in order to compute an estimate of the undesired echo that may be present. This estimate is then used to cancel echoes which accumulate due to hybrids and other effects in the voice network. This module provides up to 127 milliseconds of tail length in one way mode or up to 63 milliseconds of tail length in two way mode. This assembly contains a Telcordia CLEI (Common Language Equipment Identifier) label.
