CHAPTER64 Analog Line Testing
Mediant 1000 Gateway & E-SBC | User's Manual
➢ To view line impedance test results:
1. Access the device's Command Shell.
2. On the command-line prompt, enter the following command:
/VoiceEngn/AnalogLineTest>AnalogLineTestResults
The following example displays test results of FXO channel 4, where the Impedance 0 (600 Ohms)
returns the best (highest) ERL (25.66):
/VoiceEngn/AnalogLineTest>AnalogLineTestResults
The Analog Line Test Measurements for CID 4:
Analog Line Test successfully completed.
The AnalogLineTestResults command only displays the results of the last test that was
run.
Configuring the Best Impedance Level
After you have run the test, you can configure the FXO channel with the best impedance value
obtained from the test result.
➢ To configure the FXO channel with best impedance value:
1. Access the device's Command Shell.
2. On the command-line prompt, enter the following command:
/VoiceEngn/AnalogLineTest>AnalogLineTestConfigureImpedance
In our example, where the impedance test of FXO channel 4 resulted in the best ERL (25.66) for 0
to 600 Ohms, the command automatically configures the channel with this ERL:
/VoiceEngn/AnalogLineTest>AnalogLineTestConfigureImpedance
Best ERL (25.66) was measured with impedance 0. Channel 4 configured with this
impedance
