ima min rx:tx links : 1:1 [1-7:1-7]
Next, specify which T1 ports are used to form the IMA group. This is a list of T1 port identifiers
(1-8), each separated by commas. The BTS makes sure you enter at least as many links as you
specified for the minimum requirements above:
selected ima links : 1,2,3,4,5,6,7,8
The near- and far-end IMA protocols use an ID number to identify each other. This value must
agree with that provisioned at the far-end of the IMA link. The BTS defaults to a value of 0, but
you can specify any value from 0 to 255:
ima group id : 0 [0-255]
Group symmetry modes allow symmetric or asymmetric operation of IMA links:
ima symmetry : sym [sym|asym|asym-cfg]
IMA frame length specifies the size of the IMA frames that are being transmitted:
ima frame length : 128 [32|64|128]
The IMA alpha/beta/gamma parameters are used by the IMA frame synchronization mechanism.:
ima alpha:beta:gamma : 2:2:1 [1-2:1-5:1-5]
The IMA clock mode selects either a common or independent IMA clock mode (Exhibit 6). It is
the same as for ATM/T1.

Standard Boot Sequence
The first items in Exhibit 7 (Ethernet) and Exhibit 8 (ATM) illustrate the BOOTROM loading
and launching of the core application. This is a fixed process that cannot be altered in the field.
Auto-booting is the process that can be escaped by user intervention, (i.e., enter “config”), in
