500-19-54 Dual Channel Telephone Interface
Issue 1.2 Trilogy Communications Limited Page 9 of 19
Front Panel Controls (single channel)
When in Auto mode, an incoming call will be answered with a blip of 2 tones being sent down
the line. The tones are an indication to the caller to enter the Direct Dial DTMF tones, if required,
to call an individual panel within the Telephone group. This feature is only available when the
TIC card is installed. This is set up in the configuration software.
Whilst the Hybrid is active it will detect the presence of continuous tone (dial tone) for 6 seconds
or a DC break on the line (K-break) to detect the caller has gone on-hook and to drop the line.
This is done individually for each channel and configured by setting jumpers.
