Managing DSL

Testing the DSL Line

The MM701F has embedded diagnostics used for detecting line problems or as an aid in troubleshooting line related technical problems. These programs are used by technical support personnel to diagnose problems and determine the appropriate solutions.

1From the Main Menu, select DSL to access the ADSL Menu.

2Select Hardware/Line Diagnostics to access the ADSL Hardware/Line Diagnostics page.

3Select a diagnostic test:

•SpectrumREVERB continuously sends a R-REVERB signal for the CO to measure the upstream wideband power. This adjusts the CO transmit power level, its receiver gain, synchronize its receiver, and train its equalizer.

•SpectrumMEDLEY continuously sends a R-MEDLEY signal (pseudo-random signal) for the CO to train its frequency domain equalizer and to estimate upstream SNR.

•SpectrumPILOT continuously sends a R-PILOT signal (single frequency sinusoid) for the CO to synchronize with the modem.

•None specifies no testing.

These diagnostic programs have significance only to technical support personnel and are not discussed further in this manual.
