PTA12-300 Airborne Telephone Dialer/Adapter

The PTA12-300 Dialer/Adapter is a compact Dzus mounted telephone interface with a full function Touchtone keypad, 16 digit LED display, and integral ‘phone book’ capable of storing 16 numbers.

Utilizing the 2 wire POTS (Plain Old Telephone Service) interface from the telephone, the PTA12-300 provides complete telecom control and standard DTMF (Dual Tone Multi Frequency) dialing capabilities. The interface allows the flight crew to access the telephone system through the aircraft’s audio panel maintaining full headset operation.

A handset can also be used in parallel with the PTA12-300 to provide satcom system access for the cabin. The PTA12-300 can be used with many of today’s airborne telephone systems including Globalstar™, Iridium, Inmarsat, and airborne cellular.
