If they'll _upgrade_ you from Frac- >to Full- that way, why in hell won't they downgrade you? Below is an excerpt from my direct reply to the original question. It may be a little more complicated than you think. My first question is whether you are currently paying for M24 functionality on the T1. M24 allows the carrier to break the T1 signal down to 24 DS0 signals. You cannot assume that this is the case for a full T1. If M24 is available (is the T1 terminated in the correct place on the carrier side) then your request is fairly simple. If not, the T1 needs to be re-terminated in the correct place on the carrier side. The reason that the upgrade is easier is that M24 functionality already exists for circuits less than T1 speeds. You CANNOT assume that M24 is on a circuit sold as a full T1 because there are additional costs incurred. One factor in designing T1s is whether M24 will be required because more equipment will be necessary. >>Is SprintLink being a bonehead or am I just totally clueless? While I am not impartial regarding the participants, I do believe the sales droid should have expended more effort to understand what you wanted.
