Lucent Technologies GX 550 Technical Specifications

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
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
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
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
® Extender Shelf (ES).
