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.
