Description
The resistance of electrical current to
alternating current, measured in OHMs.
Impedance occurs when power or signal is
transferred from one circuit to another. The
setting options are:
• 600 OHMs (domestic setting)
• 900 OHMs (international setting,
depending on the country)
• External
Can be single or double.
Select this checkbox to receive caller ID digits.
Specifies the Flash Duration time in milliseconds,
with a range from 150 ms to 1000 ms. This setting
complements the Centrex Flash Support option in the
General window for the trunk.
Detects outgoing dial tone.
Disconnects signal if CO breaks loop current. You
can set the duration from 200 to 1000 ms.
Busy tone (reorder tone, fast busy tone, error tone,
etc.) or dial tone (continuous tone, etc.). This should
be used in conjunction with drop in loop current. For
COs who cannot guarantee loop break, this may be
the only option.
Slide setting adjusts the incoming volume from
-6 dB to 6 dB for every Triton Analog Trunk
channel.
The default setting is 0 dB, and it is highly
recommended not to change this setting.
Caution: Setting the volume too high will cause
distortion in voice quality and/or
missed DTMF digits.
