A communication system (100) operates on a system acquistion channel, and a set of communication channels organized into a sequence (200) which includes a set of reservation channels (202, 204) selected from the sequence (200). The system (100) includes a communication unit (113) which initiates communications by selecting one of the reservation channels (610), and by executing a collision detection protocol on that reservation channel (620). When no collision is detected, the initiating communication unit transmits, on the system acquisition channel, call information, including information for another reservation channel selected from the reservation channels (530).
