    Turn Your Phone Line Into a Party-Line. Interchange LTD allows remote access to your party-line intercom system. This 1RU rackmount interface includes a digital hybrid for connection to analog (POTS) phone lines. The front panel headset interface jack allows easy connection to your wireless phone, tablet, or computer allowing remote access through a phone call or conferencing app. The front panel DTMF keypad and headset jack allow easy call setup.

    The internal digital hybrid connects intercom audio to a standard analog telephone line without the transmit/receive crosstalk common to analog hybrids. Its DSP continuously monitors both the phone line and audio signals to deliver excellent separation. This proprietary, dual-convergence echo canceller algorithm can achieve excellent separation, typically exceeding 50 dB, without any setup and without sending a noise burst down the line.

    Listen-Always Design
    The Listen-Always design allows both the phone hybrid and the mobile phone headset interface to monitor the intercom just like any other belt pack. Listen mode is a high impedance bridging tap on the intercom line. Talk mode is enabled via a front panel switch, either Off, On, or Auto. Auto follows the phone hybrid Auto-Answer mode.
