Two TETRA direct mode gateways present on the same direct mode radio communication channel are assigned specific talk-group procedures for use in the case where both gateways are affiliated to the same talk group. Each gateway only attempts to set up a talk-group call after a random period of time, specific to that gateway, has elapsed. If a gateway detects traffic signaling activity during this time then the call set-up message will not be sent.
