Parallel Status Operation
The ITR2000A supports parallel status updating. This feature allows the dispatch positions to know the
status of the base station. To decode this information, the unit senses high level guard tone (HLGT), then
decodes the function tone (FT2) following. Due to various tone control schemes supported by the unit, it
is important to understand the rules of decoding the function tones. They are as follows:
1. If the monitor function is decoded, the unit is placed into monitor mode. If any transmit function
tone is programmed the same as the monitor function tone, that transmit function tone will not be
decoded.
2. If two transmit function tones are programmed to the same frequency, only the first of the tones in
the sequence will be decoded; the subsequent transmit function tones set to the same frequency will
not.
3. If a PTT function tone is programmed, it is not decoded since this does not contain channel control
information. If a transmit function tone is programmed the same as the PTT function tone, the
transmit function tone will not be decoded.
To illustrate the priority of the decode, the following can be used:
Highest Priority
Monitor Function Tone
Supervisor ON Function Tone
Supervisor OFF Function Tone
PTT Function Tone
Transmit Function Tone (FT1 to FT16)
Lowest Priority
