If the trunking system loses its control channel or has certain other failures, it is no longer able to operate in the trunking mode. So instead of going into a condition that stops all communication, the system enters Failsoft. In this state all transmitters (channels) turn on and operate in a 'conventional' repeater mode. The subscriber radios are able to recognize this state and switch to a predetermined frequency (one of the trunk system frequencies, but not the control channel frequency) depending on their selected talkgroup. In most systems several talkgroups will share a frequency. Some talkgroups may not be assigned a failsoft frequency and these talkgroups will cease to operate during the failsoft period. If a particular failsoft frequency has also failed, the talkgroups assigned to that frequency will also be off the air during failsoft.
