Right you are - you will indeed lose power on a T-1. They are connected to a "smartjack" and everytime you lose power they go offline. Most companies choose to retain a pots line or two as backup to make E911 calls on or whatever, but in power outages they will indeed be down. As a former BellSouth & AT&T employee and current AT&T contractor, let me know if you want to compare cost structure I can negotiate with AT&T for a POTS migration to IP Flex Reach service - the experience of the switch is often only as good as the AT&T contact conducting the provisioning process - AT&T employees are often too busy trying to make a sale and hit their quota to pay attention through the provisioning process and prevent serious issues with such migrations. There is no charge for my assistance - I am paid by AT&T directly for conducting its business as an independent contractor. Contact me if I can help you - email@example.com or cell while I am travelling today at 256-486-1988
by negotiating better rates for a T-1 service Net Keys may decide to move to, Net Keys can possibly get a better price point to help afford the steep cost differential between DSL and T-1. The decision to choose a T-1 is in his hands and at this point has nothing to do with power outages since he has already been informed there will be no significant difference in power related uptime.
