摘要
When two or more telephone sets are in use on the same subscriber's loop, their activities may not be properly detected or monitored by the central office switch. The present invention provides a method of, and an apparatus for, coordinating the signaling activities so that a hook flash or "Link" can work. A telephone set of the invention senses and synchronizes hook flashes of another set on the same loop so that a coordinated hook flash or "LINK" can be properly detected by the office switch.
