Lucent Technologies CBX 500 - Manual

Channelized DS3/1 and STM-1/E1 ATM
with IMA Module for the
CBX 3500 ™ and CBX 500 ® Multiservice Edge Switches
The Channelized DS3/1 and STM-1/E1 module with Inverse Multiplexing for ATM (IMA)
allows you to create a cost-effective, scalable service that provides interim ATM access
between DS1/E1 and DS3/STM-1 to meet the growing bandwidth needs of your customers.
With this module, you can increase the density of your existing DS1/E1 services to support
more customers and generate more revenue without increasing your equipment footprint.
This module also enables you to create cost-efficient network trunks in areas where STM-1
lines are not cost-effective or not available. You can also use the module with certain IMA-
capable Customer Location Equipment (CLE) to allow end-user access from non-ATM
interfaces, such as Frame Relay, Ethernet, private line and voice.
Applications
• Provide flexible ATM access
services between DS1/E1 and
DS3/STM-1 with IMA
• Increase port density of existing
DS1/E1 services
• Connect to DSLAMs, wireless
network access concentrators,
CPE, and other Lucent or non-
Lucent equipment
• Create cost-effective network
backbone trunks between E1
and STM-1
• Provide low-speed ATM services
Features
• Shared Input/Output processor for
DS3 and STM-1 reduces sparing
and operational expenses
• Single module enables IMA and
User Network Interface (UNI)
service delivery
• Highly flexible IMA bundle
configurations
• High port density – up to 1,176
DS1s per switch or 63 UNI or
Network to Network Interface
(NNI) E1 ports per module
• ATM Forum IMA v1.0 and
v1.1 compliant
• Eight-fold increase in buffer size
in the Flow Control Processor to
ensure network fairness and QoS
Benefits
• IMA service enables you to offer cost-effective customized ATM
access with built in redundancy for customers with bandwidth
demands greater than T1/E1 for new revenue generation with minimal
incremental investment
• Simplify operations by managing multiple low-speed physical lines as
a single logical link
• Help reduce facilities costs by using multiple less-expensive E1 lines,
instead of more expensive E3 or STM-1 lines
• Help reduce operating costs and simplify network management with
Navis ® network management software
