One E1 trunk port on an RJ-48C connector is what the VWIC-1MFT-E1, a Cisco 1-port E1 multiflex trunk voice/WAN interface card, provides. Multiflex trunk cards work as trunk interfaces for voice and data, or as fractional n x 64-kbps service for Frame Relay and leased-line WANs, and they include an integrated channel service unit/data service unit (CSU/DSU).
A straight-through RJ-48C-to-RJ-48C cable runs from the E1 port to the RJ-48C wall jack. Three LEDs show card state: LP (yellow) for a loopback or line state, AL (yellow) for a local or remote alarm, and CD (green) for a detected carrier with the internal DSU/CSU talking to the provider DSU/CSU. CD is on in normal operation.
The card goes into the slots of the NM-HDV and NM-HDV2 network modules and the NM-1A-OC3MM-1V, NM-1A-OC3SMI-1V and NM-1A-OC3SML-1V modules, and into the NM-HD-2VE for voice only. It is not supported in the 2-WAN-slot modules such as the NM-2W, or in the NM-1V, NM-2V, NM-HD-1V and NM-HD-2V.
The 2-port E1 card is the VWIC-2MFT-E1, and the 1-port T1 card is the VWIC-1MFT-T1. Further voice cards are in Cisco interface cards.
