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.
Providing carrier-class availability, performance and reliability
• 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
level agreements.
Industry leading availability
The GX 550
®
switch delivers
advanced availability features.
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 hardware-
based switching during software reconfiguration
• Automatic protection switching (APS) to provide
millisecond recovery on transmission
facility failures
