Details: Alpha Communication IF900 Audio Transceiver Interface

The standard Ring-Master intercom station is connected to the central exchange on one twisted pair using DC inband signaling together with the voice (0-5000Hz).Two IF900 are required for connecting an intercom station to the central exchange. The connection between the two IF900 is 4 wire 600 ohm copper (one pair transmit, one pair receive). The 4 wire interface on each IF900 can interface to standard transceivers using the 300-15000Hz bandwidth. 12V DC at 500mA is available from the IF900 to power the transceiver.

Features

  • The DC can not be transmitted over fiber optic or radio transceiver.
  • The IF900 overcomes this limitation by converting the DC to a pilot tone (10KHz).
  • The pilot tone is added to the audio and transmitted to the transceiver
  • The receiver will filter the pilot tone from the audio and convert it back to DC signaling
