group The bay number (1–2) and the IMA group number (1–16) in the format
bay.group. For example: 1.16
version The protocol version of the IMA group.
1 = IMA version 1.0
2 = IMA version 1.1
minLinks The minimum number of links that will allow the IMA group to be
operational (Range: 1–16). The minLinks value is configurable ONLY for
IMA version 1.1. For IMA version 1.0, the minLinks value is always 128.
txImaId The IMA ID number transmitted in the IMA ID field of the ICP cell
(Range: 0–255).
txFrameLen The length of transmitted IMA frame in megabytes. For IMA version 1.0, the
txImaFrameLength value is always 128. For version 1.1, the
txImaFrameLength value can be 32, 64, 128, or 256.
diffDelayMax The maximum differential delay in milliseconds (Range: 1–279). Defaults:
T1 = 275
E1 = 220
groupUpTime The group up time. Range: 0–400000 milliseconds. Default: 10000.
groupDownTime The group down time. Range: 0–100000 milliseconds. Default: 2500.
verFallback Enables/disables version fallback on the IMA group. Enter 1 to enable
version fallback on the specified IMA group, or 2 to disable version fallback
on the specified IMA group.
Note You must set version fallback on the card level with the
cnfimaparms -fallback <1|2> command before you set it for each
individual IMA group with the cnfimagrp -vfb <1|2> command.
autoRestart Enables, disables, or re-uses IMA auto restart functionality for the current
group. Enter 1 to disable IMA auto-restart. Enter 2 to relearn IMA
auto-restart, or enter 3 to reuse a previous IMA auto-restart.
rxImaIdExpected Identifies the expected received IMA ID. The IMA Id is a number in the
range from -1 through 255.
