Abstract
A telephone communication system having a cordless telephone operating in conjunction with a cellular transceiver. A subscriber line interface circuit (SLIC) is controlled by a microprocessor in the cellular transcriber. The SLIC can be controlled to provide standard telephone service to other telephone sets, and includes circuits for testing for foreign voltages on the telephone lines prior to providing SLIC service. Standard RJ-11 jacks are utilized for coupling the telephone sets to the communication system to provide standard telephone service by way of the cellular network.
