I have here a Nortel Option 11c with a remote site that has about 80 digital sets in place, it is connected back to the main office via 2 T1's. I need to move 40 of these sets to a new location and have already contacted a vendor about doing the work. I just had a few more questions about it that I knew would get answered here quickly. When disconnecting 1 of the above mentioned T1's, will it disrupt all service to the old location or is just 1 a rollover for the other?
