H04J3/1647 - CPC Classification

Classification description:

Time-division multiplex systems in which the time allocation to individual channels within a transmission cycle is variable, e.g. to accommodate varying complexity of signals, to vary number of channels transmitted; Fixed allocated frame structures; Plesiochronous digital hierarchy [PDH] Subrate or multislot multiplexing
