ALERT METHOD FOR CORDLESS TELEPHONES

摘要

The method of the present invention controls the alert generation of a cordless telephone, thus synchronizing all cordless telephones at a particular number. The base unit of the cordless telephone sends a ring start message in the subaudible message stream to the handset unit. The handset then monitors the audible portion of the channel for a tone. Upon reception of the tone, the alert is generated until the handset receives the sub-audible ring stop message from the base unit.
