I am looking for some explanation regarding the below output from one of our Cisco routers. Its a CE Router.

> Loop is facing which direction?
> What does that inband CSU code mean?

T1 0/2/0 is up. (Line Looped (inband CSU code)) (Line Loop by Remote) Applique type is Channelized T1 Cablelength is short 110 Receiver has no alarms. alarm-trigger is not set Soaking time: 3, Clearance time: 10 AIS State:Clear LOS State:Clear LOF State:Clear Version info Firmware: 20090408, FPGA: 13, spm_count = 0 Framing is ESF, FDL is ansi & att, Line Code is B8ZS, Clock Source is Line. CRC Threshold is 320. Reported from firmware is 320. Data in current interval (370 seconds elapsed): 0 Line Code Violations, 0 Path Code Violations 0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins 0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs Total Data (last 24 hours) 62 Line Code Violations, 11411 Path Code Violations, 48 Slip Secs, 7 Fr Loss Secs, 11 Line Err Secs, 18 Degraded Mins, 195 Errored Secs, 145 Bursty Err Secs, 7 Severely Err Secs, 13055 Unavail Secs
Someone told me that a remote device has sent an "Inband CSU code" in response to which the CE router has put a loop on its own controller facing the network/PE/Service provider. Was expecting if someone with expertise could confirm it.
Secondly Can someone confirm if the loop could be cleared with a shut - no shut on the controller?
