The TA-312/PT and the TA-43/PT are two-wire, battery-operated field telephones. They may be used in a point-to-point wire system or in any two-wire ring-down subscriber position of a telephone communications system. The Handset H-60 contains a push-to-talk switch which connects power for talking. The TA-312/PT has a built-in Receptacle Connector U-79/U for use with a headset and an associated EXT-INT switch; the TA-43/PT does not. The TA-43/PT is being replaced by the TA-312/PT. The TA-955/PT dual tone multi frequency (DTMF) adapter allows push button operational interface with automatic analog switches.
