Match Impedance button
Changes the Impedance setting to the best match for the
selected trunk channel, and then measures noise and re
-
turned echo with this impedance setting. Results are dis-
played in the Diagnosis section of the dialog box. The system
automatically runs a matching test upon system startup, un
-
less you disable the feature. If later you connect a new ana-
log line to an empty port or replace an existing line, you need
to click this button to best match the impedance.
Match Result button
Shows the result obtained the last time the Match
Impedance button was clicked for that trunk.
Disable Impedance Match
During System Startup
Check to disable automatic impedance matching during
system startup.
Caller ID Receiving
Select as None, FSK or DTMF for receiving caller ID digits.
For North America, the caller ID is FSK signal on analog
trunk.
Centrex Flash Duration
(ms)
Specifies the Flash Duration time in milliseconds, with a
range from 150 ms to 1000 ms.
Out of Service With Trunk
Seizure
When checked, if the trunk is set to Out of Service, the sys-
tem will busy out the trunk. The CO will treat this trunk as a
busy line and WILL NOT place a call to this trunk. (By default,
this option is unchecked.)
Enable Dial Tone
Detection (Outgoing)
When enabled, the trunk channel must detect outgoing dial
tone prior to making the call.
Enable Answer Debounce
(Incoming)
Enables a timeout period of 2 seconds (for ignoring false CO
disconnect signal), after answering an incoming call.
Loop Break Duration (ms)
Disconnects signal if CO breaks loop current. You can set the
duration from 200 to 1000 ms. 600 ms is common in North
America.
Tone Disconnect
Busy tone (reorder tone, fast busy tone, error tone, and so
on) or dial tone (continuous tone, and so on). This should be
used in conjunction with drop in loop current. For COs who
cannot guarantee loop break, this may be the only option.
Receiver/Transmission
Gain
Slide setting adjusts the gain from -6 dB to 6 dB for every
Triton Analog Trunk channel.
The gain is not adjustable, by default. The user needs to run
the diagnosis first to change the gain. The diagnosis process
determines the max gain based on the diagnosis results.
The default setting is 0 dB, and it is highly recommended
that you not change this setting.
Caution! Setting the volume too high will cause distortion in
voice quality and/or missed DTMF digits.
