Total Access 1500 Dual FXO/DPTThe ADTRAN Total Access 1500 Dual FXS/DPO and Total Access 1500 Dual FXO/DPT provide for a two-wire 600/ 900 ohm + 2.16 F interface between a VF transmission and signaling facility and a PCM interface. The two units contain the necessary circuitry to convert two voice data signals from the customer s loop to PCM digital data and to convert PCM digital data from the carrier to voice data.
