Lucent Technologies GX 550 User Manual

Improve ROI with a system that provides world-class reliability and industry leading port densities to anchor carrier-class multiservice networks.

The Lucent GX 550® Multiservice WAN Switch provides the multiservice protocol support, capacity, port density, and availability you need to provide ATM and FR services on a single, unified multiservice network.

Designed for the core, the carrier-class GX 550® switch provides the availability, service-aware routing and high-speed switching you require at the heart of your multiservice network. With 25 Gbps full duplex

ATM throughput, 32 Gbps full duplex packet throughput, and optical interfaces that connect directly to the transmission network, the GX 550® switch has the power to anchor the most demanding service provider networks.

Robust QoS and industry-standard interfaces make the GX 550® switch a natural component of high-speed, high-density access deployments.

Providingcarrier-class availability,performanceandreliability

The GX 550® switch has a sophisticated feature set that provides carrier-class availability. These features go beyond redundant power supplies and cooling systems to include:

The ability to switch over from the active to the standby switching fabric with no data loss or service interruptions

Distributed routing and signaling control to help avoid single points of failure

In-service software upgrades that can reduce user traffic disruptions by taking advantage of hardwarebased switching during software reconfiguration

Automatic protection switching (APS) to provide millisecond recovery on transmission

facility failures

Priority-based routing of hundreds of thousands of circuits per second to help keep services up and

running if the transmission facility cannot be recovered

Stratum 3 holdover timing to support continued operations, even if the switch loses its primary network-timing source

Traffic prioritization control to help ensure that management traffic is delivered regardless of network congestion

The GX 550® switch also provides a rich set of line and circuit statistics to help you demonstrate to your business customers that your network has met the

availability requirements in your service

Industry leading availability

The GX 550® switch delivers advanced availability features.
