Measuring the Rx Level of a Trunk Channel

In order to perform this test, you need to obtain the local CO's Milli-Watt Test Number
from your CO. When dialing this number, a 0dB tone is sent. For example, if your number
is 510-252-9712, the Milli-Watt Test Number from the local CO is 510-252-0020 (the
prefix 510-252 is the same).
1. Write down the Rx Gain, then set it to 0dB and click OK.
2. Write down the Impedance setting, then change it to 600ohm, and click OK.
3. Call the number you got from your CO, as noted above.
4. Click the Test Rx Level button. When the test is complete, the Test Rx Level dialog
box appears.
5. Click OK. The Rx Level measurement is displayed in the Diagnosis section of the
main dialog box.
If you call your local CO's Milli-Watt Test Number, the acceptable range for Rx Level
should be between -6dB and -3 dB, with -5dB being ideal.
6. Restore the Impedance and Rx Gain settings, and click OK.

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:
