I've got a site with a PRI from Qwest. About once a month the PRI circuit seems to go down. I'll arrive on site and see no error lights on the smart jack.

Once I call Qwest and have the bounce the D Channel, all is well. Has anyone ever had this problem? I've changed out EVERYTHING on the KSU at this site. The sofware is the newest version, nothing helps.

Normally I would blame it on Qwest, however next door I have another site running a PRI and it has not gone down once, the only difference is this is a 128 X instead of the E.

Has anyone seen this issue before?
