Lucent has extended the proven leadership, carrier- class reliability, and performance of its multiservice switch family to meet the demanding requirements of the evolving multiservice edge. The CBX Multiservice Edge Switch portfolio includes two scalable switching systems that have been carefully designed to deliver flexible, high-performance services from a compact edge platform. This portfolio includes the:
•CBX 3500™ Multiservice Edge Switch: The newly- architected 70 Gbps, 16-slot CBX 3500™ switch provides maximum service flexibility and port density at a dramatically reduced cost per port to increase the profitability of Layer 2 services, add new services, and converge and interwork multiservice traffic onto an MPLS core.
•CBX 500® Multiservice WAN Switch: The widely-deployed 5 Gbps, 16-slot CBX 500® switch provides the multiservice capabilities, high-speed trunking, proven reliability, and high port density you need to cost- effectively aggregate Layer 2 and Layer 3 edge services.
The CBX portfolio helps service providers optimize data service delivery to expand revenues and lower capital and operating expenses. The CBX switches help maximize profits from Frame Relay, ATM, and private line services and reduce costs by transporting all services over MPLS with robust QoS. Service providers can also use the switches to generate new revenue from differentiated IP/MPLS and Ethernet services, such as Layer 2 and Layer 3 Virtual Private Networks (VPNs), IP-enabled Frame/ATM, and Ethernet Virtual LAN (VLAN) services.
With high port densities, a wide range of service interfaces, and superior software and hardware fault tolerance, the CBX switches deliver all services with the availability, QoS, and performance end users expect. The CBX portfolio is managed by the Navis® network management system, which enables streamlined operations to speed service provisioning and control costs.
Maximize profitability and flexibility to grow existing services and add new, high-demand services
High-port densities and efficient switching architectures enable the CBX switches to cost-effectively deliver ATM, Frame Relay, IP, MPLS, and Ethernet services at speeds ranging from DS0 to OC-48c/STM-16c. Service providers can also minimize costs and protect existing investments by sharing line modules within the CBX portfolio.
The CBX 3500™ Multiservice Edge Switch further reduces costs by incorporating the latest Network Processing Unit (NPU), mesh, and power distribution technologies into its innovative switch design. The new architecture also includes Universal I/O modules to increase service flexibility while minimizing equipment costs.
Efficiently converge and interwork multiservice traffic across an IP/MPLS core while preserving QoS and SLAs
Service providers can deploy either CBX switch as part of a Lucent-Juniper Multiservice MPLS Core Solution to transport edge services using high-speed ATM interfaces and ATM-over-MPLS trunking. This solution uniquely delivers all services according to ATM QoS and service level agreements (SLAs), without sacrificing network reliability. Alternatively, service providers can use high-speed Packet over SONET (POS) interfaces and pseudowire emulation edge to edge (PWE3) on the CBX 3500™ Multiservice Edge Switch to transport services across any standards- based MPLS core.
Lucent was the first to deploy automated ATM-over- MPLS trunking, which it uses in the Lucent-Juniper Multiservice MPLS Core Solution to transport Layer 2 services over MPLS. Today, Lucent and Juniper are leading the effort to develop ATM-to-MPLS control plane interworking and any-to-any Ethernet-ATM- Frame Relay service interworking standards to increase the utility of future ATM-over-MPLS and L2 interworking solutions.
Deliver all services with unprecedented, proven carrier-class reliability, availability, and performance
The CBX portfolio has been designed to provide carrier-class reliability and availability. CBX switches feature fault-tolerant architectures, reliable Lucent MXOS™ Multiservice Switch Operating Software, and performance monitoring to help service providers deliver premium services to business customers.
The CBX 3500™ Multiservice Edge Switch is built on the proven heritage of the CBX 500® and
GX 550® Multiservice Switches, which have been field-tested and hardened in the world’s largest service provider networks.
