IMA Group Configuration

If you have an IMA group configuration for the CBX 500 3-Port Channelized DS3/1
IMA IOM or CBX 3500 3-Port Channelized DS3/1 IMA module, use these
instructions to determine the MCR class.

1. Calculate the MCR class using the following formula:

describes the arguments in the formula.

.

2. When you have calculated the MCR class, round the figure up to the nearest

integer value.

Table D-6.
