BXM T3/E3 Broadband Switch Module
Cell Buffering
• Large ingress and egress cell buffer architecture
• 204,800 to 1,024,000 cells stored per card
– Accommodate large traffic bursts
– Avoid network congestion and cell discard
– Suited to TCP/IP traffic
Intelligent QoS (Quality of Service) Management Suite
Connection Admission Control (CAC)
Automatic Routing Management
• Automatic end-to-end connection management mechanism
• Deterministically allocates bandwidth and routes VCs
autonomously over optimum network paths
• Automatic rerouting preserves service integrity during network
failures
Advanced CoS (Class of Service) Management
• Up to 16 class-of-service queues, with independent service
algorithms dedicated to each interface in the network
Optimized Bandwidth Management
• Dedicated queue- and rate-controlled servers for each VCC/
VPC
• Dynamic thresholding, providing fairness and more than
95 percent utilization
ATM-Frame Relay (FR) Service Interworking
• Provides transparent end-to-end connectivity, operating two
services on a single switch platform
Switched Virtual Circuits
• Signaling protocol per ATM Forum UNI Specification V.3.0
and V.3.1
• E.164/NSAP addressing per ATM Forum UNI
Specification V.3.1
• Support for Private Network-Network Interface (PNNI) per
ATM Forum PNNI Specification V.1.0
Fault Management and Reporting
• Compliant with Bellcore GR-253-CORE
Alarms
• Loss of Signal (LOS)
• Loss of Pointer (LOP)
• Loss of Frame (LOF)
• Loss of Cell Delineation (LOC)
• Alarm Indication Signal (AIS)
• Remote Defect Indication (RDI)
• Alarm integration up/down count
Performance Monitoring
• Performance monitoring provided for line, section, and path
• Bit Interleaved Parity (BIP) error detection
• Far-End Block Error (FEBE) count
• Unavailable Seconds (UAS)
• Errored Seconds (ES)
• Severely Errored Seconds (SES)
• Header Checksum (HCS) monitoring
Statistics
• ATM statistics collected on a per-VC basis
• Four levels of ATM-layer statistics collection provided
OAM
• Segment and end-to-end Operations, Administration and
Maintenance (OAM) loopbacks supported per Bellcore
TA-NWT-001248
• External OAM segment flows, consisting of segment loopback
cells per ATM Forum UNI Specification V.3.1 and ITU-T I.371
• Generation and detection of AIS and RDI OAM cells
• OAM cell generation and loopback facility supported for
diagnostics and self-test purposes
