Superior capacity and scalability

The GX 550® switch offers the high-speed, industry- standard, optical interfaces essential to core and access applications such as ATM access, private line and DSL. A single switch supports up to 156 OC-3/STM-1 ports, 39 OC-12/STM-4 ports, or 9 OC-48/STM-16 ports – although most deployments use a rich mix of port types.

The GX 550® switch also provides:

•Agile connection buffering with advanced traffic management to efficiently mix all traffic classes and users on a single network while maintaining QoS

•High rate of switched virtual circuit (SVC) setup – 5,000 SVCs per second and 8 million calls per busy hour for continued scalability

•Industry-leading virtual circuit (VC) support with a permanent virtual circuit (PVC) capacity of up to 1.28M simultaneous circuits, SVC capacity of up to 6.4M simultaneous circuits per GX 550 Switch

•Service-aware routing that provides end-to-end QoS and creates enhanced services, such as virtual private networks (VPNs)

•Advanced networking features to support secure and wide-ranging connectivity with closed user groups (CUGs), security screening, and SVC-to-PVC interworking

Switches. MXOS™ enables delivery of multiple services from a single network infrastructure, allowing service providers to maintain existing profitable data services and avoid the need for costly overlay IP networks. It leverages Lucent’s experience in building the most reliable voice networks and includes reliability features, such as improved fault management and improved manual and automatic service recovery. These features have been adapted to bring greater reliability to data switching networks. MXOS™ helps reduce operations costs with pro-active tools for network data collection and analysis, which quickly identify potential problems and prevent service disruptions.

Key features

•Protocol-independent multiservice switching — Flexibility to change your service mix to meet demand

•Small footprint — Scale to 25 Gbps full duplex capacity (32 Gbps for IP/MPLS) per chassis to provide 50/64 Gbps capacity per rack

•Superior availability — Lossless fabric switchover and 1+1 Automatic Protection Switching (APS) provide proven reliability

•Excellent scalability — High port densities, high virtual circuit support, and distributed routing and signaling increase service capacity

Cost-effective data transport

Provides ATM-level QoS for all multiservice traffic

Today’s data networks utilize OC-12/STM-4 rates at the core, but increasing data transport rates are quickly making it critical to upgrade to OC-48/STM-16 backbones. As data moves at OC-48/STM-16 speeds and as ATM switches become more resilient, the distinction between switching and transmission blurs. Rather than using a traditional SONET/SDH ring backbone, you have the option to connect GX 550® switches directly to fiber through DWDM equipment or direct fiber connections. This moves statistical multiplexing into the transmission facility—giving you more cost-effective and efficient data transport. In addition, this streamlined network can help lower operating costs and speed service provisioning.
