AS0351 - PABX to Radio Interface

The AS0351 can interface to a simplex radio set from a trunk port of any standard telephone system. As standard the unit links to a single radio set but could be modified to link to multiple radios with key selection.

When the unit is accessed it opens the return audio path from the radio set.

When keyed it sends outgoing audio and the PTT tone (normally 2.97KHz) to the transmitter. A ‘bip’ is also returned to the user to verify in Tx mode.

The unit has two in-built interfaces for external PTT footswitches, these switches are equipped with lamps showing CALL & PTT status.

The radio can also be keyed from the PABX using standard DTMF tones from the handset with a ‘*’ enabling the PTT and ‘#’ releasing.

A full accessory kit is available for the system with adaptors to allow connection of footswitches over Cat5, expander units for up to 6x footswitches and wall mount display units to show system status to users.
