I'm considering renting a unit, which is actually the downstairs part of a house. The main house has a phone line connected and active, but the unit doesn't have its own line.
According to a spark rep I spoke to, there is only one line connected at the address, and has only been one. They mentioned that if the underground cable going to the main house carried 2 pairs, that cable could be used to supply the line for the unit. The rep said that most cables carry 2 pairs so there shouldn't be any digging or anything drastic required.
Does that all sound correct? I'm concerned about the cable not having 2 pairs. Hard to know without a tech going out I suppose.
