Customizing SoundStructure Designs
5 - 67
Ring Tone
Ring tone enabled will cause the SoundStructure device to play ring tones into
the local room when the telephone line rings.
If Ring Tone is disabled no ring tone will be heard although a phone_ring
status message will be generated by the SoundStructure device when the
phone is ringing.
Auto Hang-up
Auto hang up enabled will allow the system to auto hang up based on loop
drop detection.
DTMF Gain
DTMF gain allows the user to adjust the level of the DTMF digits that are
played into the local room while dialing the telephone interface.
Adjusting the DTMF gain does not adjust the level of the DTMF digits that are
sent to the telephone line.
Tone Gain
Tone gain adjusts the level of the tones, including the ring tone, that are played
into the local room including the entry and exit tones.
Dial Tone Gain
Dial Tone gain adjusts the level of the in room dial tone when the phone is
taken off hook.
Flash Delay
Flash delay sets the flash timing in milliseconds when the flash feature is
executed.
Country Code
The country setting of the telephone interface must be set prior to first use of
the telephone line. The country code only needs to be set once to set the
appropriate telephone line interface parameters that are region dependent.
Once the country code is set, the phone line may be tested by clicking the
phone icon. This will take the selected phone line off-hook. Assuming the
signal routing is correct through the matrix, and the phone line is connected
and active, dial tone will be heard in the local room.
