Cisco EC-MFT-64 64 Channel Multiflex Trunk Dedicated Echo Cancellation Module

Cisco Multiflex Trunk Dedicated Echo Cancellation (MFT ECAN) Module is dedicated resource for the Cisco Enhanced ITU-T G.168 ECAN feature, providing robust echo cancellation performance for demanding network environments. This module is a daughter card that attach to Cisco Second-generation Multiflex Trunk Voice/WAN Interface Cards (MFT VWIC2 cards).

The Cisco enhanced ITU-T G.168 ECAN feature was originally introduced in Cisco IOS Software Release 12.2(13)T on several platforms, including Cisco 2600 Series and 3600 Series multiservice access routers. Subsequent features extended support to additional platforms, network modules, and advanced integration modules. The processing and memory resources of the dedicated ECAN modules enable the echo canceller to be configured with predefined settings and an extended 128-ms echo tail buffer, providing robust echo cancellation performance in these more demanding network environments.

It is possible to install a Cisco 64-Channel MFT Dedicated ECAN Module on a 1-port MFT VWIC2. However, the extra echo cancellation channels will not be used.

Enhanced ITU-T G.168 ECAN feature: Enhanced ITU-T G.168 ECAN feature complies with and exceeds the performance requirements specified in the ITU-T Recommendation G.168 Digital Network Echo Cancellers (2000) standard. Provides future echo cancellation enhancement capability through Cisco IOS Software upgrades, Provides control of the echo canceller coverage through the size of the echo cancellation buffer, ranging from 8 to 64 ms (128 ms of echo cancellation coverage requires dedicated ECAN module). Configures the worst-case echo return loss (ERL), ranging from 0 to 6 dB, Provides control over echo cancellation convergence, enabling faster convergence for multiple echo reflectors and improved double-talk detection. Provides control for enabling and disabling the nonlinear processor (NLP), which replaces the residual echo at the output of the echo canceller with comfort noise based on the actual background noise of the voice path. Reports various metrics, including combined echo return loss (ACOM), ERL, and worst-case echo return loss, Reports statistics for location of the largest reflector (tail) and the internal state of the G.168 ECAN feature, Provides test-mode support for manually freezing, thawing, and clearing the echo canceller registers
