Chapter 2 Cisco IGX 8400 Series Cards

Universal Frame Module

Table 2-33 shows the front and back cards supported for the universal frame module (UFM).

The UFM provides Frame Relay (FR) service across a connection between two IGX nodes. The module

supports ELMI and Frame Relay-to-ATM service interworking, and can support FR traffic through T1,

E1, V.35, X.21, or HSSI interfaces.

There are three front cards in the UFM card set. See the “UFM-C Front Cards” section on page 2-51 for

more information about the two UFM-C front card models, and see the “UFM-U Front Card” section on

page 2-52 for information on the UFM-U front card. See Table 2-33 for information on front and back

card compatibility.
