The A-Port or the IS41 GSM Migration (IGM) feature must be enabled before the chg-is41opts command can be entered.
For the chg/rtrv-sid commands, the A-Port or IGM feature must be enabled before the cpctype=mnp parameter can be specified.
Recovery
Display the status of A-Port and IGM features. Enter the rtrv-ctrl-feat command.
If the feature does not appear in the output, then the feature is not enabled. If the feature has a status of OFF, then the feature is enabled but is not turned on.
Enable the desired feature if necessary. Refer to IS41 GSM Migration User's Guide to enable the IGM feature and to A-Port User's Guide to enable the A-Port feature.
Re-enter the command that generated the error message.
