ABSTRACT:
Cordless telephones generate cell relay packets. Packets from each cordless telephone are polled by an upstream polling unit avoiding multi-unit interference. Cell packets are transmitted via a cable TV system. Radiated frequencies of the cordless telephones are shifted in frequency as they enter or leave the TV feeder cable to allow frequency reuse. The upstream polling unit appends header information on the cell packets and converts them into standard SONET ATM protocol packets. The cell relay packets are switched by a cell relay type switch to create a cost-effective, alternative telephone system.
