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
Description
