● VWIC2-1MFT-G703-- 1-port RJ-48 multiflex trunk (E1 G.703)
● VWIC2-2MFT-G703-- 2-port RJ-48 multiflex trunk (E1 G.703)
Note: These baseboards can also provide hardware echo cancellation if there is a daughter card (EC-MFT-32
or EC-MFT-64) mounted on the baseboard. For more information, refer to the
Voice Port Configuration Guide
on Cisco.com.
Note: Although unstructured G.703 operation is particular to E1 operation, the VWIC2-1/2MFT-G703 cards
also support structured T1 operation.
Integrated Drop and Insert Capability
The drop and insert feature enables the removal of DS0 time slots from one E1 interface and insertion into
time slots of the other E1 interface. This feature is available in VWIC applications. If you configure drop and
insert, be sure that the E1 framing under the controllers involved (the tdm-groups configuration location) is the
same. If you use different frame types, the signaling bits may not be read properly. This failure occurs during
the drop of a channel from one controller and insertion into a channel from another controller. Drop and insert
time slots do not need to be contiguous.
Configure
In this section, you are presented with the information to configure the features described in this document.
