2.2.3.6 Repeater Wake-up Provisioning
When there is no inbound traffic for a specified duration (Subscriber Inactivity Timer), the repeater
stops transmitting and enters an inactive state. In this inactive state, the repeater is not
transmitting, but instead it is listening for transmissions. When the user or radio needs to transmit
through the repeater, the radio sends a wake-up message to the repeater.
Upon receiving the wake-up message, the repeater activates and begins transmitting idle
messages. The radio then synchronizes with the repeater before it begins its transmission.
The repeater wake-up sequence is configurable within the radio. The number of wake-up attempts
(“TX Wakeup Message Limit“) and the time between the attempts (“TX Sync Wakeup Time Out
Timer”) may be altered if required to operate with other vendor’s systems. It is recommended that
these values remain at default while operating on MOTOTRBO systems.
