This document describes the various Universal Frame Relay Module (UFM) front and back cards, and
identifies the appropriate cables to use with the different back cards. The UFM series is a set of high−density,
high−performance Frame Relay modules for Cisco IGX 8410, IGX 8420, and IGX 8430 wide−area switches.
The UFM delivers standards−compliant User Network and Network−to−Network (UNI/NNI) interfaces with
high port and connection density at a lower per−port cost for both enterprise customers and service providers.

Two versions of UFM card sets exit:

Channelized (UFM−C)

• 

Unchannelized (UFM−U)
