H04J0003120000 Arrangements providing for calling or supervisory signals 1
H04J0003140000 Monitoring arrangements 1
H04J0003160000 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 (H04J0003170000, H04J0003240000 take precedence);; 1
