ABSTRACT:
A channel allocation system for selecting the earliest available switch port and time division multiplexed channel for an outgoing transmission in a network of switch elements interconnected by a series of communications paths. An availability table for maintaining the free/busy state of each channel on each switch port in the switch element is provided. Means are additionally provided for limiting the search of the availability table for the earliest available channel to certain desired switch ports and channels.
