Abstract

The present invention discloses a method and apparatus for receiving Type II CID data in an environment containing multiple off-hook cordless telephones, all being fitted for receiving CID data, and all residing on the same subscriber line. This is achieved by coordinating the sending, receiving, and acknowledging (i.e., handshaking) of muting control signals within a cordless link between a designated master telephone unit and designated slave telephone extensions.
