Lucent has extended the proven leadership, carrier-
class reliability, and performance of its multiservice
switch family to meet the demanding requirements of
the evolving multiservice edge. The CBX Multiservice
Edge Switch portfolio includes two scalable switching
systems that have been carefully designed to deliver
flexible, high-performance services from a compact
edge platform. This portfolio includes the:
•CBX 3500™ Multiservice Edge Switch: The newly-
architected 70 Gbps, 16-slot CBX 3500™ switch
provides maximum service flexibility and port density
at a dramatically reduced cost per port to increase the
profitability of Layer 2 services, add new services, and
converge and interwork multiservice traffic onto an
MPLS core.
•CBX 500®Multiservice WAN Switch: The widely-deployed
5 Gbps, 16-slot CBX 500®switch provides the
multiservice capabilities, high-speed trunking, proven
reliability, and high port density you need to cost-
effectively aggregate Layer 2 and Layer 3 edge services.
The CBX portfolio helps service providers optimize
data service delivery to expand revenues and lower
capital and operating expenses. The CBX switches help
maximize profits from Frame Relay, ATM, and private
line services and reduce costs by transporting all
services over MPLS with robust QoS. Service providers
can also use the switches to generate new revenue
from differentiated IP/MPLS and Ethernet services,
such as Layer 2 and Layer 3 Virtual Private Networks
(VPNs), IP-enabled Frame/ATM, and Ethernet Virtual
LAN (VLAN) services.
With high port densities, a wide range of service
interfaces, and superior software and hardware
fault tolerance, the CBX switches deliver all services
with the availability, QoS, and performance end
users expect. The CBX portfolio is managed by the
Navis®network management system, which enables
streamlined operations to speed service provisioning
and control costs.
Maximize profitability and flexibility to
grow existing services and add new,
high-demand services
High-port densities and efficient switching architectures
enable the CBX switches to cost-effectively deliver ATM,
Frame Relay, IP, MPLS, and Ethernet services at speeds
ranging from DS0 to OC-48c/STM-16c. Service providers
can also minimize costs and protect existing investments
by sharing line modules within the CBX portfolio.
The CBX 3500™ Multiservice Edge Switch further
reduces costs by incorporating the latest Network
Processing Unit (NPU), mesh, and power distribution
technologies into its innovative switch design. The
new architecture also includes Universal I/O modules
to increase service flexibility while minimizing
equipment costs.
Efficiently converge and interwork
multiservice traffic across an IP/MPLS
core while preserving QoS and SLAs
Service providers can deploy either CBX switch as part
of a Lucent-Juniper Multiservice MPLS Core Solution
to transport edge services using high-speed ATM
interfaces and ATM-over-MPLS trunking. This solution
uniquely delivers all services according to ATM QoS
and service level agreements (SLAs), without
sacrificing network reliability. Alternatively, service
providers can use high-speed Packet over SONET
(POS) interfaces and pseudowire emulation edge to
edge (PWE3) on the CBX 3500™ Multiservice Edge
Switch to transport services across any standards-
based MPLS core.
Lucent was the first to deploy automated ATM-over-
MPLS trunking, which it uses in the Lucent-Juniper
Multiservice MPLS Core Solution to transport Layer 2
services over MPLS. Today, Lucent and Juniper are
leading the effort to develop ATM-to-MPLS control
plane interworking and any-to-any Ethernet-ATM-
Frame Relay service interworking standards to
increase the utility of future ATM-over-MPLS and L2
interworking solutions.
Deliver all services with unprecedented,
proven carrier-class reliability, availability,
and performance
The CBX portfolio has been designed to provide
carrier-class reliability and availability. CBX switches
feature fault-tolerant architectures, reliable Lucent
MXOS™ Multiservice Switch Operating Software, and
performance monitoring to help service providers
deliver premium services to business customers.
The CBX 3500™ Multiservice Edge Switch is built
on the proven heritage of the CBX 500®and
GX 550®Multiservice Switches, which have been
field-tested and hardened in the world’s largest
service provider networks.
