8 Copyright © 2004 Marconi Corporation plc. All rights reserved 8 BXR Dual SCP Configuration Optional dual SCPs provide protection The primary active SCP emits a "heartbeat" at regular intervals Primary/Secondary vs. Active/Standby SCPs Primary – is set as the default SCP to control the system after it boots Secondary – is set as the backup SCP should the primary fail Active – is the SCP that is currently controlling the system Standby – is the backup SCP

All rights reserved 9 BXR Fabric Modules Variable-length packet fabric Support up to 12(+1), 40 Gbps fabrics per chassis One fabric for every four port cards Contiguous population Protocol agnostic fabrics Data is distributed evenly across all fabrics N+1 fabric protection Scales from 240 Gbps to a 480 Gbps system with fabric redundancy Fail over protection is provided by a "hitless" reconstruction process LEDs Ejection/Insertion Levers Lock +

10 Copyright © 2004 Marconi Corporation plc. All rights reserved 10 BXR Port Cards Input/Output Modules Each port card supports up to 10 Gbps of full-duplex capacity Three types: ATM IP-Aware (IPA) ATM Packet over SONET (POS) + OC-3c OC-12c LEDs OC-48c

11 Copyright © 2004 Marconi Corporation plc. All rights reserved 11 ATM Port Cards Cell-based interfaces capable of normal ATM functions PVC, SVC, SPVC Traffic management, per-VC queuing, scheduling ILMI, PNNI routing ATM port card hardware 16 port OC-3c/STM-1 in multimode and single mode 16 port OC-12c/STM-4* in multimode and single mode 4 port OC-48c/STM-16 in single mode 1 port OC-192c/STM-64 in single mode * Each port configurable as OC-12c/STM-4 or OC-3c/STM-1 Ejection/Insertion Levers (with locks)

12 Copyright © 2004 Marconi Corporation plc. All rights reserved 12 IP-Aware (IPA) ATM Port Cards An IP-aware ATM interface has ATM capabilities plus capabilities in an IP/MPLS network: Hop-by-hop routing when there is no LSP for the destination Can originate or terminate an LSP, encapsulating/decapsulating packets using RFC 1483/2684 (bridged/routed PVCs) Support for ATM and MPLS control planes on the same port Pseudo Wire Emulation Edge-to-Edge (PWE3) Provider Edge (PE) capability A topology change can make a transit LSR become an LER, the IPA card performs both roles. Ingress and egress to the MPLS network require IP look-ups A network failure could cause a transit LSR to unexpectedly become an LER that cannot perform IP lookups

13 Copyright © 2004 Marconi Corporation plc. All rights reserved 13 IPA ATM Port Card Hardware Port card types, listed by interface: 8 port OC-3c/STM-1 in multimode and single mode 8 port OC-12c/STM-4* in multimode and single mode 2 port OC-48c/STM-16 in single mode * Each port configurable as OC-12c/STM-4 or OC-3c/STM-1

14 Copyright © 2004 Marconi Corporation plc. All rights reserved 14 Packet over SONET (POS) Port Cards SONET-based IP interfaces allow direct connection of IP devices OC-12c and OC-48c POS port cards can be trunks for aggregated IP traffic Hop-by-hop routing supported Can originate or terminate an LSP Provider Edge (PE) functionality Multiservice capability over MPLS with PWE3 toward the network core
