ABSTRACT:
A method and system for multiple access telephone communications is described. The system utilizes one or more base units connected to subscriber lines, and multiple extension units in communication with each base unit via building power lines. Secure multiple access coding is used to prevent eavesdropping and interference. Extension units may employ cordless telephone technology. Caller ID information transmitted with incoming telephone signals may be transmitted to extension units via building power lines and displayed on the extension handset or cradle.
