These logs just show the system coming back on line after a reboot, When you come in the morning can you make a call over each one of your tie circuits before you reset anything? does the call fail or are you basing your failure on the "indeterminate " status of the circuit? Have you tried doing a DT Clear (plid) to clear up any alarms?
"the faulty circuit shows frame slips toward the CPE" Where are you getting this info from? what piece of equipment is telling you this?
The 2K will show you a digital link alarm if there is a problem like slips,clocking, carrier failure. and Doing a DT Clear will correct these errors. They are info alarms to let you know something has happened that requries some attention but not usually service effecting.
Let us know
