Abstract

See full text

A selective call communication system for use by an untrained person is provided. The communication system includes a number of telephones located in different locations, connected to a central switching unit. A number of selective call radios, each having an address, are assigned to the central switching unit. Upon the use of the telephone, the central unit identifies the telephone in use, and initiates an alerting call to the corresponding selective call radio automatically. The selective call radios may be pagers or two-way radios. Other features such as radio to radio communication, and radio to telephone network communication may be incorporated into the system.
