There’s a dependency on the loop length and equipment used but last 10 Meg Metro-E I designed only required 6 pairs.

Keep in mind even if there is a 50-pair feeder coming in to the building there may not be enough vacant pairs to the x-box or from the C.O. In most cases I would think a Telco would tell you there’s going to be a delay in delivering the service, not that ya’ll can’t have it.
