Abstract

A subscriber inputs data into a centralized database of the public switched telephone network to control communication services which the network provides via a number of telephone lines assigned to the subscriber. The subscriber offers the communication service over the lines to selected ones of the subscriber's own customers. The input data may relate to a variety of different parameters for use in controlling the service. For example, the data may identify specific lines, define periods of time when service should be available, define authorization codes, establish restriction on what types of calls can be made or specify parameters for controlling the routing of the calls over specific trunks groups, or the like. The subscriber can thereby limit the time service is available, can control which customers can use the communication service, can restrict what types of calls the customers can make or can control the telephone network to route calls over the subscriber's private facilities.
