Completed DS3 Hotcut

I joined bridge with customer for DS3 hotcut. I borrowed OC48 facility with available vacant timeslot to use for tunneling in a Cisco router from another circuit to pre-test new portion of customer circuit. Using borrowed test router I tested good to hard loop from customer at customer premise demarc. I pulled test set out of future path of customer circuit, normalled future path of customer circuit, deleted current circuit, and mapped customer equipment over to future path. Hotcut successful. Network elements used were Tellabs 6500 BBDCS, Alcatel iMTN BBDCS, Alcatel 1680 ADM, and Cisco router.
