L3149B (C200) Advanced Tone Remote Desk Set Operation
15
Parallel Status Operation (Tone Operation Only)
The L3149B Desk Set supports parallel status updating. This feature allows all dispatch positions to
know the status of the base station.
To decode this information, the unit actually senses high level guard tone (HLGT), then decodes the
function tone that follows. Due to various tone control schemes supported by the unit, it is important to
understand the rules of decoding the function tones.
1. If the monitor function is decoded, the unit is placed into the monitor mode. If any transmit function
tone is programmed to be the same as the monitor function tone, that transmit 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 to be the same as the PTT function tone, the
transmit function tone will not be decoded.
4. If a transmit function tone is programmed to be the same as a tone supervisor tone, the supervisor
function will be decoded.
To illustrate, the priorities of the decode function are as follows:
Highest priority: Monitor Function Tone
Supervisor On Function Tone
Supervisor Off Function Tone
PTT Function Tone
Lowest priority: Transmit Function Tone (F1 to F16)
