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.
