Performing Impedance Match on Your Own
For each individual analog trunk that is connected to the CO when AltiServ
starts up, AltiWare automatically selects an impedance profile to best
match the Triton trunk interface with the CO. In the unlikely event that this
automatic selection does not yield the optimal voice quality, you may want
to disable the feature and select the best impedance by trial and error
method.
To disable automatic impedance matching, check the Disable Impedance
Match During System Startup check box.
Using the Match Impedance Button
Whenever a new analog line is connected to an empty port or is replacing
an existing line from AltiAdmin/ACM Admin, you will need to use the
Match Impedance button to select the best impedance profile.
To do this, follow these steps:
1. Click the Impedance Match button. While the impedance match is in
process, you’ll see a “progress” box.
When the process is complete, the Match Impedance dialog box is
Rx Level at 600 Ohms The Rx Level measurement at 600 Ohms, obtained
by clicking the
Test Rx Level button. See Test Rx
Level button, below.
Test Rx Level button Tests the receiving level of the trunk channel on a
call to your local CO’s Milli-Watt Test Number after
you set the
Impedance parameter to 600 Ohms and
the Rx Gain to 0dB. Results are displayed in the Rx
Level at 600 Ohms field.
