3-Port Channelized DS3/1 ATM with IMA
Input/Output (I/O) Module for the
CBX 500
®
Multiservice Switch
The 3-Port Channelized DS3/1 with Inverse Multiplexing for ATM (IMA) Input/Output Module
can be used to create a cost-effective, scalable service that provides interim ATM access
speeds between DS1 (1.5 Mbps) and DS3 (45 Mbps). Because the module offers extremely
high port density, you can use it to provision more customers and create more revenue
opportunities without increasing your equipment footprint. You can also use the module in
conjunction 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. This
configuration eliminates the complexities of ATM access for your customers, while preserving
your flexible and reliable ATM service management structure.
Applications
• Provide low-speed ATM services
• Offer flexible bandwidth solutions
between DS1 and DS3 in 1.5 Mbps
increments using IMA
functionality
• Support higher density ATM services
at standard DS1 and DS3 speeds
• Allow end user access from
familiar, non-ATM interfaces
Features
• High port density—up to 1,176
DS1s per switch
• Up to 42 software-configurable
IMA bundles per card can be
created containing one to
eight DS1 links
• ATM interfaces supported directly
or non-ATM interfaces through
IMA-capable CLE
• ATM Forum IMA v1.1 compliance
• Flow Control Processor ensures
network fairness and QoS
Benefits
• Provision more customers to increase revenue opportunities without
expanding your footprint
• Preserve your ATM service management structure while supporting
non-ATM access services
• Help reduce operating costs and simplify network management with
