DIGITAL CORDLESS PHONE

摘要

PROBLEM TO BE SOLVED: To provide a digital cordless phone where slave units can make inter- slave-unit direct speech and extension speech at the same time without the need for revising an existing master unit and for a mode revision instruction from the master unit. SOLUTION: This invention provides the digital cordless phone that has the master unit and the slave units registered to the master unit, and when a slave unit 1 registered to the master unit is set to a home standby mode, the slave unit 1 automatically receives both a control signal CCH from the master unit and a signal f3 for inter-slave direct speech.
