Cisco VWIC-2MFT-T1 - Multiflex Trunk Voice/WAN Interface Card Expansion Module Installation Instructions Manual page 2

Each card also features protection switch solid state relays on the line interfaces, which together with
redundancy logic and relay control added in a Cisco IOS feature set on the MWR 1941-DC router, can
be used to provide T1/E1 Protection Switching between redundant routers in applicable
implementations.
For information on the Cisco MWR 1941-DC router implementations and Cisco IOS software available
Note
for those implementations, see the Cisco MWR 1941-DC Mobile Wireless Edge Router Software
Configuration Guide.
The Cisco MWR 1941-DC router provides three WAN interface slots, which allows support for 6
T1/E1s.
Physical Characteristics of the VWIC-2MFT-T1-DIR, VWIC-2MFT-E1-DIR
Each T1/E1 Multiflex VWIC provides two RJ-48C interfaces. You can distinguish between T1 and E1
Drop and Insert interface cards by the labeling on the faceplate, as shown in
Figure 1

Note The labeling under the port and on the lower left of the card indicates whether it is a T1 or E1 card. Also,
due to limited space, the last dash was omitted from the label on the card (VWIC-2MFT-E1DIR and
VWIC-2MFT-T1DIR).
