ABSTRACT:
A telephone switching office having essential service protection is disclosed. As each service request is received it is put in a common queue. Periodically, and regardless of the load, the common queue is examined for requests that have not been served with a given time interval. If these requests are from essential lines, they are put in a special queue. When a server, such as a digit receiver or processor is available the special queue is served prior to the common queue.
