BXR-48000 Chassis

Power Switching, Interfaces and Control Cooling Expansion from single chassis to dual chassis can be a hitless field upgrade (although we recommend an initial dual-chassis installation if possible)

BXR-48000 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


BXR-48000 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

up to 10 Gbps of full-duplex capacity

Three types: ATM IP-Aware (IPA) ATM Packet over SONET (POS)

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/InsertionLevers

(with locks)


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


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



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


POS Port Card Hardware

Port card types, listed by interface: 12 port OC-3c/STM-1 in multimode and single mode 12 port OC-12c/STM-4* in multimode and single mode 4 port OC-48c/STM-16 in single mode



Port Card Scheduling and Queuing

POS and IPA port cards have 16 hardware queues Room to concurrently support ATM service categories,

Diffserv, IntServ and best-effort IP Configurable strict and weighted round robin queues Provides support for unique service offerings


BXR-48000 Card Carrier/TCM

The card carrier supports: TCM and AIM The TCM(s) are optionally

redundant The TCM provides system

synchronization and manages the timing sources: Primary and secondary line

timing sources Redundant BITS sources Internal Stratum 3E clock

TCM(s) are located on chassis A only
