Lucent Technologies GX 550 - Manual

GX 550 ® Multiservice
WAN Switch
Scale ATM networks and increase your capacity to deliver ATM, IP / MPLS, and frame relay services
at the network edge. Designed for the core, the GX 550 ® Multiservice WAN Switch provides the
availability, service-aware routing, and high-speed switching you require at the heart of your
multiservice network. With optical interfaces and DWDM support, the GX 550 ® switch can
connect directly to your optical network. This enables you to move statistical multi-plexing into
your transmission facility — helping to create more cost-efficient data transport. Expand service
functionality into low-speed native ATM, Private Line and voice transport applications with the
GX 550 ® Extender Shelf (ES).
Applications
• Scale ATM networks to
OC-48c/STM-16
• Transport ATM and IP/MPLS
• Provide Circuit Emulation Services
(CES), ATM services and
unchannelized access with the
GX 550
® ES
Benefits
• Create new revenue opportunities
through multiservice capabilities
• Provide ATM-level QoS for all
multiservice traffic
• Balance core and access functions
for improved ROI
• Simplify network management and
reduce operating costs with Navis ®
network management software
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) 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, industry-leading Virtual
Circuit support, and distributed
routing and signaling increase
service capacity
• Expandable design — Low-speed
ATM interfaces supported
including CES
