CD-2-CAR makes it economically possible to readout up to four DIGIT DTMF ANI CODES. Any mobile unit in a fleet provided with an DTMF ANI encoder can be identified instantly by the dispatcher.

The DTMF ANI rate should be 10 characters per second, maximum. The displayed DTMF ANI numerals scroll onto the display from right to left and remain visible continually until another ANI code is received when another mobile unit transmits. Instant readout is provided with CD-2-CAR. All fleet radios that respond to normal dispatch calls send the DTMF ANI identifier information which is seen immediately by the dispatcher on the screen of his CD-2-CAR.
