In Car Monitor (ICM)

The ICM feature allows the MSU to monitor PSU Voice traffic and is configurable in the
MSU codeplug as follows:
•
ICM is enabled / disabled globally in the MSU via the 'ICM Allowed' Field
•
If 'ICM Allowed' is programmed in the MSU then ICM operation is further
configured on a per MSU channel basis via the 'ICM Allowed' codeplug field.
•
ICM functionality is further configured to be triggered by either Hang Up Box
(HUB) on / off transitions OR via menu item / button on the MSU control head or
keypad microphone.
When ICM functionality is configured to be triggered via HUB on/off then 'ICM Selected'
operation takes place when the MSU microphone is placed on HUB, 'ICM All' operation
will take place when the MSU microphone is taken off HUB.
For details on how to program the ICM functionality and options in the MSU, please refer
to the corresponding Motorola Documentation.
