Method for seizing time slots of a time-division multiplex system with dynamic multiplexers

Abstract From the Canadian patent

In a time-division multiplexing system data are supplied, to the multiplexer with different speeds. Depending on the speed, time slot groups are allocated to the data with the, number of allocated time slots increasing with the speed. The search for groups of free time slots occurs in a fixed sequence. Data to which time slot groups at the end of the fixed sequence have been allocated, are relocated to time slot groups which have become free nearer the beginning of the sequence. The allocated time slot group for the forward transmission direction is signalled to the multiplexer of the remote station which in turn occasions a corresponding allocation of time slots for the reverse …
