If You Need to Improve the Rx Level
If the Rx Level measurement is between -6 to -9 dB, and IP phones are used, take the
following steps to increase the gain for the Triton analog trunk to IP phone connection:
1. Go to VoIP Board configuration and click the
Advance button.
2. Increase the Transmitting gain to IP Extension to 9 for the Triton Analog Trunk. (Do
NOT change the gain in the trunk property of the Triton Analog Trunk Board, since
it may impact the echo canceller performance.)
If the Rx Level measurement is worse than -9dB (for example, -10 dB) you should
contact the CO to adjust the line loss to the acceptable range.
If You Don’t Have the Milli-Watt Test Number
If you don’t have the local CO’s Milli-Watt Test Number, you can follow the steps below
to measure the line loss when calling two local trunks:
1. Copy \C:\Post Office\Phrases\Lang1\phrase9900 to \C:\Post
Office\Phrases\LangCustom folder. Rename it an unused phrase name, for example,
phrase0990 (the number must be less than 1000).
This phrase is a 1 kHz test tone.
2. Select an unused AA and set the AA to play the prompt phrase you named in step 1
(0990 in this example).
