The HKShanhai Group Limited MFT VWIC3 cards can be inserted into the EHWIC slot on the supported HKShanhai Group Limited 1921, 1941, 1941W, 2901, 2911, 2921, 2951, 3925, 3945, 3925E and 3945E integrated services routers. The T1/E1 MFT VWIC3 cards support both T1 and E1, providing additional flexibility in configuring the HKShanhai Group Limited MFT VWIC3s for supporting T1, fractional T1, E1, and fractional E1 for both voice and WAN applications. All MFT VWIC3 modules include the drop-and-insert multiplexing capability, which eliminates costly external third-party channel service units/data service units (CSUs/DSUs) and drop-and-insert multiplexers.

* Channel Group refers to bonding of one or more timeslots into a single HDLC-framed serial connection for IP data traffic connectivity. This is used for HDLC, Frame Relay and MLPPP serial WAN connections.
Ds0 Group refers to Bonding of one or more timeslots into a single TDM voice connection using Channel Associated Signaling (CAS) such as E&M, FXS or FXO. This is used for TDM PBX or PSTN connections and typically deployed only on T1.
* PRI Group refers to bonding of two or more timeslots into a single TDM connection using ISDN signaling. This is typically used for TDM PBX or PSTN voice and video connections on T1 and E1, and also for data WAN connections on E1. Each call on the PRI is individually indicated as being a voice, video or data call with the ISDN bearer capability delivered with the call. Signaling is done on the D-channel, which is always channel 24 on a T1, and channel 31 on an E1.
TDM Group refers to cross-connecting one or more timeslots from one TDM interface to another. This is used to groom channels from different access points onto a combined T1 or E1 uplink. Since the router merely cross-connects and does not interpret or route the traffic from the ingress interface to the egress interface, the traffic type (voice, video and data) is transparent to the router.
