NTP has nothing to do with the clocking on the T1/E1 lines. The latter is usually provided by the carrier that supplies the circuits. Any reason you don't want to use theirs?

Well, as long as the BITS device supports NTP and is reachable by IP, I suppose:

ntp server ip-addr-of-BITS-clock prefer

ntp server other-NTP-clock

ntp update-calendar time-zone

clock timezone zone GMT-offset [minutes-offset]

clock summer-time [your-daylight saving-time-zone] recurring

service timestamps debug datetime msec localtime show-timezone

service timestamps log datetime msec localtime show-timezone
