GX 550 Multiservice  
WAN Switch  
Anchors ATM core networks to  
deliver highly reliable ATM and  
frame relay services.  
Benefits  
• Improve ROI and anchor carrier-class multiservice networks with  
a system that provides world-class reliability and industry leading  
port densities  
• Deliver carrier-class availability, performance and reliability  
• Support more end users and generate higher revenues with  
the capacity and scalability you need  
• Transport data cost-effectively by connecting with DWDM  
• Avoid the need for costly overlay networks by adding IP services  
to your existing ATM and frame relay (FR) networks with  
MXOS™ software  
• Simplify network management and help reduce operating costs with  
Navis® network management software  
 
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.  
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  
Key features  
Protocol-independent multiservice switching —  
Flexibility to change your service mix to meet demand  
• 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  
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  
• Service-aware routing that provides end-to-end QoS  
and creates enhanced services, such as virtual  
private networks (VPNs)  
Excellent scalability — High port densities, high virtual  
circuit support, and distributed routing and signaling  
increase service capacity  
• Advanced networking features to support secure and  
wide-ranging connectivity with closed user groups (CUGs),  
security screening, and SVC-to-PVC interworking  
Provides ATM-level QoS for all multiservice traffic  
Cost-effective data transport  
Simplify network management and reduce  
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  
operating costs with Navis® software  
®
Navis network management software enables you to  
deliver new services to your business customers  
quickly and profitably. It provides end-to-end,  
standards-based management of Lucent IP/MPLS,  
FR, and ATM multiservice core and access networks.  
Navis software offers exceptional management of a  
®
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.

GX 550 switch network, using industry-standard  
TCP/IP protocols such as SNMP, TFTP and Telnet. In  
addition, a command line interface provides Ethernet  
and asynchronous serial console connections for  
network monitoring, configuration and performance  
statistics collection. Navis® software also delivers  
sophisticated add-on functions, such as automated  
provisioning, real-time statistics monitoring, and  
accounting—giving you excellent network  
management control.
