Introduction 1-5
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.
• BCC-3-64
• BCC-4 supporting 19.2 Gbps switching with the BXM cards supporting egress at up to
1600 Mbps and ingress at up to 800 Mbps.
• Hot Standby Redundancy
• MGX 8220 Release 4.1, which will include:
— BNM-155 interface to BXM on BPX switch
— FRSM support for both SVC and PVC frame relay connections with ESP
— AUSM support for both SVC and PVC ATM connections with ESP
— FRSM-8 with ELMI
— IMATM-B
— AUSM-8
— CESM/4T1E1
— FRSM-HS1 (HSSI and X.21 interfaces)
— SRM 3T3
• Access Products
— FastPAD MM and MP
— Cisco 3810
• Virtual Trunking.
• Inverse Multiplexing ATM (IMA).
• Enhanced Ingress buffers for ASI-155 and BNI-155 to 8K cells for Release 8.1 and up.
• BPX switch OC3 network and service interfaces on the BNI and ASI cards.
• High-speed switching capacity.
• Powerful crosspoint switching architecture.
• 53-byte cell-based ATM transmission protocol.
• Twelve 800 Mbps switch ports for network or access interfaces with BNI and ASI cards.
• Three DS3 or E3 ATM network interface ports per card (BNI).
• Totally redundant common control and switch fabric.
• Up to 20 million point-to-point cell connections per second between slots.
• Switches individual connections rather than merely serving as a virtual path switch.
