Cisco® Multiflex Trunk Dedicated Echo Cancellation (MFT ECAN) Modules are dedicated resources for the Cisco Enhanced ITU-T G.168 ECAN feature, providing robust echo cancellation performance for demanding network environments. The modules are daughter cards that attach to Cisco Second-generation Multiflex Trunk Voice/WAN Interface Cards (MFT VWIC2 cards). The dedicated ECAN modules are available in 32- and 64-channel configurations, which match the requirements of the 1- and 2-port T1/E1 MFT VWIC2s, respectively. The 64-channel MFT ECAN Module is shown in Figure 1. Figure 2 shows the module attached to a 2 port T1/E1 MFT VWIC2.
