Key Telephone System (KTS)
KTS is an arrangement of multi-line telephones and associated equipment that permits the station user to depress buttons (keys) to access different central office or PBX lines, as well as to perform other functions. Typical functions include answering or placing a call on a selected line, putting a call on hold, using the intercom feature between phones at the same location, or activating a signal buzzer.
