Hi, I'm having a problem with a client's T1. The tech for LGN which relays the Verizon T1 (last mile) to our LGN DS3 on a Lucent TNT told me that we need to do our own clocking and that the TNT should be using an internal clock source. This hasn't been a problem before, but if we were to do the clocking, how would we guarantee we could talk to Verizon T1s? Thank you...Ed -- Regards...Ed Thank you.
