Cisco Systems 8600 Series manual Imatm-B

Continuing Features with Release 9.1

—de-route delay timer

—connection routing groups by cell loading

•ATM and Frame Relay SVCs, and Soft Permanent Virtual Circuits (SPVCs) with Extended Services Processor

ESP is an adjunct processor that is co-located with a BPX switch shelf. The ESP provides the signaling and Private Network to Network Interface (PNNI) routing for ATM and Frame Relay SVCs via BXM cards in the BPX switch and AUSM and FRSM cards in the MGX 8220.

•Cisco StrataView Plus NMS enhancements including additional management and provisioning capabilities.
