When the channel groups mode is enabled only one physical port is supported by the WIC slot. Add/Drop multiplexing is still supported in this mode since only one
port terminates on the router.

BERT support requires Cisco IOS 12.1(1)T or later releases.
5
V.54 loopback requires Cisco IOS 12.1(1)T or later releases.

9
The 2-port G703 VWIC can be configured as a standard E1 interface and therefore has all the features of the VWIC-2MFT-E1-DI when not in unframed G.703
