Illegal Carrier

Illegal Carrier is a CPS/RM setting in the SLR repeaters that, when enabled, will make the repeater generate a RDAC alarm if an interfering signal is detected. The interfering signal must be present for longer than the Illegal Carrier Timer with a signal strength of more than the Illegal Carrier Threshold. The severity of the alarm can be configured to be either Major; Minor or Informational.

The repeater regards a DMR transmission with an incorrect Colour Code or any other non-DMR signal as an illegal carrier.

The repeater behaviour depends what Illegal Carrier Alarm is set to. If set to Informational, the repeater may continue to operate normally, depending on the nature and duration of the interference. if set to Major, the repeater will be become disabled until it gets reset.

If the repeater is part of a Capacity Plus or Capacity Max system and Illegal Carrier Alarm is set to anything other than Informational, it will remove itself from contention for being a Rest Channel or Control Channel host whenever there is interference. If an illegal carrier is detected by a control channel host, this function will be transferred to the next available control channel capable repeater.
