Re: Generic tech question-dsl but no dial tone on one extension? I would pull out the voltmeter, and see if there is voltage drop at the no-dialtone jack. There should be about 48 volts when no phone is offline, and maybe 10 volts, or so, across the line with an off-hook phone plugged in. If you see lack of voltage, that should make for easy troubleshooting.
DSL might be able to work thru an open with enough existing capacitance, but it will probably will not be at full speed and reliability. |
