Default Re: 746 no dial tone. Inexperienced repairer hoping for help.

To answer your last question first, yes, ADSL & VDSL do not require the 50v supply on the line.

But I think that's a red herring because without the line voltage you wouldn't hear side-tone (blow-back) or be able to make or receive calls.

Maybe you have an open circuit winding in the ASTIC coil.

P.S. have you tried measuring a known voltage source on your new meter, say a 9 Volt battery?

It might be that your meter probes are too fat to make contact to through the IDC connectors in the photo.
