The VWIC-1MFT-G703 is a Cisco 1-port E1 multiflex trunk interface card with G.703 support. G.703 support lets the card pass unstructured E1 traffic that conforms to the ITU-T G.703 standard. Multiflex trunk cards provide voice and data access to the PSTN domain through TDM ports and include an integrated CSU/DSU.
The NM-HDV2 network module takes this card when it is used with PVDM2 modules, and in that setup the network module provides the interface to the PBX, the PSTN or a WAN. PVDM and PVDM2 modules are not interchangeable: PVDM modules go in the NM-HDV network module only, and PVDM2 modules go in the NM-HDV2 only. The ATM OC-3/STM-1 circuit emulation service network modules do not support the VWIC-1MFT-G703.
The same G.703 card family includes the 2-port VWIC-2MFT-G703 and the second-generation VWIC2-1MFT-G703 and VWIC2-2MFT-G703, and the VWIC2 cards accept the EC-MFT-32 and EC-MFT-64 echo canceler modules. Other voice and WAN cards are in Cisco interface cards.
