Alcatel Lucent Multiservice WAN Switches CBX 500

The widely deployed 5 Gbps CBX 500® Multiservice WAN Switch delivers carrier-class ATM, frame relay, circuit emulation, and IP services. Support for a wide range of input/output (I/O) modules and a distributed I/O module-based processing design enable the CBX 500 switch to offer high port and service densities from a compact chassis.

Flow control conserves network resources by using switch-to-switch signaling to manage congestion at the network edge. The high-performance switching fabric, modular architecture, and cross-point technology enable you to cost-effectively grow your edge network.

Use the CBX 500® Multiservice WAN Switch to cost-effectively aggregate Layer 2 and Layer 3 edge services.

Scale, simplify and consolidate public networks
Avoid costly overlay networks by adding IP services to your existing ATM and frame relay network
Generate new revenue opportunities with flexible bandwidth services based on Inverse Multiplexing over ATM, Multilink Frame Relay, and subrate capabilities
Gain voice, video, and data support that is flexible enough to capitalize on new market opportunities
Leverage limited real estate and simplify your physical plant with high-density service modules
Simplify network operations and speed service activation with end-to-end network and service management
Differentiate ATM, frame relay, IP and MPLS services with Quality of Service (QoS), and preserve Service Level Agreements (SLAs)
Benefit from proven, carrier-class performance and reliability


The scalable, reliable CBX 500® Multiservice WAN Switch supports multiple services with unified network management.

High-port density, multiservice support, and proven reliability deliver superior price/performance

Supports a wide range of high-speed, high-density service modules, including 8-port T3/E3, 4-port OC-3c/STM-1 modules and 1-port OC-12/STM-4 modules
Interchangeable service modules with the CBX 3500® Multiservice Edge Switch provide greater investment protection and flexibility
High port-densities, high VC support and distributed routing and signal processing increase scalability
Flow control gives you the tools to run rt-VBR (real-time – Variable Bit Rate), nrt-VBR, ABR (Available Bit Rate) and UBR (Unspecified Bit Rate), and ensure fairness in the network for all services

Fault tolerant architecture delivers proven carrier-class reliability and service availability

Redundancy protection for key modules: 1+1 Automatic Protection Switching (APS)/Multiplex Section Protection (MSP) on SONET/SDH interfaces help support non-service impacting upgrades and protect against card failures
Routing and signaling protection: Distributed routing and signaling control help avoid single points of failure. If a network or service disruption occurs, priority-based routing of hundreds of thousands of circuits per second quickly restores services
Reliable architecture: Fully redundant hardware, control, and power components protect against hardware failures and reduce network downtime. If a failure occurs, automatic failover, Stratum 3 holdover timing and hot-swappable modules can restore services quickly without losing data

Robust software architecture helps reduce costs and simplifies network management

The carrier-class, feature rich MXOS™ Multiservice Switch Operating Software simultaneously supports ATM, frame relay, and IP services – providing exceptional reliability, service flexibility, and investment protection.
Proactive network data collection and analysis tools can reduce operating costs by quickly identifying problems with the potential to disrupt services.
Management Software offers extensive configuration, performance management, point-click-done provisioning and security support for multiple services from a single platform.
