ABSTRACT:
In a digital communications system with a time-division multiplexed medium having a transmit r.f. channel and a receive r.f. channel on an internal network having a head end multiplexer and interface for external connection of calls, timeslots are allocated to maximize time slot usage between internal calls and external calls by dynamically differentiating between internal call types and external call types, or calls between nodes within the internal network between an internal node on the internal network and an external node connected through a trunk, and, based on differentiation for the external call types, claiming a free timeslot for the internal node on the transmit r.f. channel and using the corresponding timeslot on the receive r.f. channel to establish communication between the internal node and the external node.
