TA-312 Field Phone
The analog, 2-wire, battery operated TA-312/PT replaced and will interoperate with the World War II and Korean War EE-8 field phone. The rugged and reliable TA-312 was used from the 1950s through the 1980s before being superceded by the TA-838 analog field phone. TA-312's continue in use throughout the U.S. forces as well as many allied countries.
TA-312 Field Phone
The TA-312/PT (and the earlier, similar TA-43/PT) 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 the headset and an associated EXT-INT switch. The TA-43/PT does not have these features.
