ABSTRACT:
The present invention relates to a system for channel-specific releasing and blocking of telephone channels in "outgoing" signaling converters and in "incoming" signaling converters of a pulse code modulation (PCM) system. Alarm signals which influence the signaling converters are generated in monitoring devices. The first alarm signal serves for accommodating the signal transmission and occurs immediately given faults in the system and occurs delayed given disturbances in the system. The second alarm signal effects a blockage of the telephone channels with respect to new seizure and is immediately triggered given disturbances in the system and given faults in the system. Given this method of alarm, a channel-specific and time-differentiated release and blocking of telephone channels occurs independently of the presence of a central processing device in a signaling converter equipment.
