It is unusual that an Yes most are but, the multiconductor you will find in most apartment jacks is called E-wire. It is looped through *all* the outlets on a particular run. Therefore there can be *many* faults in the IW. Combined with the fact that there is almost never enough good wire to start with, you may not have that second pair available. If you live in an older building than that you might very well have one three conductor wire running to your apartment. > >...........................PacBell will put in a second line, if I want. > >There are two reasons why this is unacceptable.

Good advice about looking first.

Mostly good advice from Robert deleted above.... but.... Just give the old Pac Bell man a try. He will show up for the work and after inspecting the job, give you an estimate. It's not cheap but it might not be as expensive as you think. If you don't like the price then cancel the order. What the Customer Service clerk was telling you was that there are *currently* no second service pairs hooked up to your apartment. That doesnt mean that I couldn't get you hooked up in fifteen minutes. If you need more information then e-mail for my telephone number. I'll be glad to help out.
