7. Trunk
Configuration
Impedance The resistance of electrical current to alternating
current, measured in Ohms. Impedance occurs when
power or signal is transferred from one circuit to
another. When a trunk interface impedance is greatly
mismatched with the CO analog line, it may result in
static noise and echo heard by IP phone users.
AltiWare automatically selects the impedance
profile that best matches the Triton trunk interface
with the CO. In the rare case where you are not
getting the best match, you can disable this feature by
checking Disable Impedance Match During
System Startup, and you can set the Impedance
manually.
Match Impedance
button
Changes the Impedance setting to the best match for
the selected trunk channel, and then measures noise
and returned echo with this impedance setting.
Results are displayed in the Diagnosis section of the
dialog box. AltiWare makes this selection
automatically upon system startup, unless you
disable the feature. If later you connect a new analog
line to an empty port or replace an existing line from
AltiAdmin/ACM Admin, 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.
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 enabled, the system automatically takes the
trunk out of service with trunk seizure.
Enable Dial Tone
Detection (Outgoing)
When enabled, the trunk channel must detect
outgoing dial tone prior to making the call.
