ABSTRACT:
An alerting cadence control system for a telephone network having a telephone exchange, subscriber transmission equipment connected to the telephone exchange, and a plurality of telephone sets each connected to the subscriber transmission equipment. The subscriber transmission equipment includes a plurality of subscriber interface cards and subscriber-shared alerting cadence control means, each of the cards incorporating a switch for performing alerting cadence switching of each telephone set. The subscriber-shared alerting cadence control means has a memory for control setting data in the format of a table in which is written a control program for controlling the switch connected to each telephone set. Where alerting cadence control is to cover a new subscriber service offered to a new telephone set, the applicable data in the table are modified from the telephone exchange under remote control without replacement of the subscriber interface card for that telephone set. This provides easy alerting cadence control over service requirements of newly added subscribers.
