Signaling
When ANI signaling is used, the ANI is transmitted from a mobile or portable radio and
received by the consoles. The more common signaling methods in use include the DTMF,
5/6 Tone, GE-STAR, and MDC-1200 formats. The ANI signaling is decoded by the DCC,
forwarded to the CIC, and finally sent to the console. The output of the decoded
information is different for DTMF than for the other methods. DTMF is decoded and sent
to the console on a digit-by-digit basis. GE-STAR, 5/6 Tone, and MDC are decoded,
stored, and only sent to the console if the decoded string matches certain decoding criteria
(such as timing or check bits). For DTMF, no preceding digit is sent. Other types
preceding the “F” character are sent to the console before the ANI string. In the case of
emergency IDs, an “E” character precedes the ANI string, indicating an emergency
condition. ANI decoding is performed by software selection for a Universal or Tone/Local
DCC. Refer to Tone/Local Software Configuration on page 54 for a description of ANI
configuration for the Universal and Tone/Local DCC.
DTMF ANI codes may be from 1 to 6 digits in length. 5/6 Tone ANI codes may be either
five or six digits in length, plus one preceding character. MDC ANI codes are always four
digits in length, plus one preceding character.
Modes
There are two general modes involving ANI: Reverse Selective Calling (RSC) and PTT
ID ANI.
