Ding ding ding ! The last TDA install I did, I did just that. We
brought out the AMPS to a 66 block and ran two 25-pair cables from
another 66 block to a patch panel, terminating 2 pairs per jack on a
24-port panel. It didn't disturb the order of the cables from the
phone system, and it gave us 8-wire patch cord flexibility back into
the infrastructure. Plus, when you change out your TD system, because
of lack of parts, you just mount the new system, and plug in the AMPS
and change the cross connects. Your patch cables stay the same.
