Universal Switching Module Enhanced

•The maximum throughput is 310 Mbps—two times the OC-3 (STM1) rate. This maximum applies whether the back card is a 2-port or 4-port back card. In practical application, this maximum rate means that most trunk applications with an OC-3 interface would use the 2-port back card.

•The UXM-E supports ATM-to-Frame Relay network and service interworking.

•For the ABR connection types, the UXM-E supports EFCI marking, Explicit Rate Stamping, and Virtual Source/Virtual Destination (VS/VD).

•The UXM-E supports Y-cable redundancy with hot standby for very fast switchover.

•The front card has 128K cell buffers.

•For statistics support, the UXM-E provides real-time statistics counters and interval statistics collection for ports, lines, trunks, and channels.

•The UXM-E can form a logical trunk by grouping more than one T1 or E1 port. The name of this (purchased) option is Inverse Multiplexing over ATM (IMA).

•The on-board diagnostics are loopback, self-test, and background.

UXM-E Interfaces

Table 4-4is a list of the UXM-E back cards. Figure 4-3shows the UXM-E front card. Table 4-5defines all possible combinations for the states of the front card status LEDs (Fail, Active, and Standby).
