Anyone able confirm for me the standard voltage you recieve down a telecom landline?

Just noticed the DSL and dialtone missing from my line at home. Opened up the demarc and noticed im only getting 10.5 volts when i disconnect the house wiring and hook up the multimeter only to the copper pair coming in from the street. Next door on the line we are getting 47 volts which i am assuming is correct.
Just want to confirm that im right in my assumption. I think the chorus techs working down the road a bit may have messed something up as it coincides with some digging project they have been working on for the last couple of days.
