RE: point to point T1 troubleshooting [7:4987]
Clear the stats on the interface. If you see input CRC count rising the report the T1 to the carrier (telco). It appears that you still have carrier (DCD) so you still have a T1. But I cannot tell if it is bad since the counters were cleared 18 hrs ago, and I don't know what type of testing that may have been done that might have caused the errors being seen.

RE: point to point T1 troubleshooting [7:4987]
Park, I had exactly the same problem this morning on a point-to-point circuit. I power cycled CSUs on both ends and everything came back up. If that doesn't work, and your CSUs support it, you may want to throw a loopback towards one end and check to see if the router sees it. The interface should go to UP/UP/Looped, that would verify your path.

RE: point to point T1 troubleshooting [7:4987]
Park, if you look at the output you can see that the last time you cleared the counters on the interface was approximately 18 hours ago: Last clearing of "show interface" counters 18:08:32 Since that time you have had: 8940 input errors, 1913 CRC, 0 frame, 6028 overrun, 0 ignored, 999 abort 3438 interface resets This would indicate that there is a problem with the T1 line or the cabling between the router(s) and their interface with the T1 whether it be through a V.35 into a CSU, or a straight cable into the NIU or smartjack. I would recommend calling the circuit into the carrier that provides it and asking them to test the line. In my experience about 97% of the time it is a carrier issue such as a bad cross connect in the CO. It is also possible, although very unlikely, that the router interface itself has a problem but you will probably find that this is a carrier issue and that it can be repaired by them. -Original Message- From: park jeongwoo To: [EMAIL PROTECTED] Sent: 5/18/01 11:04 AM Subject: point to point T1 troubleshooting [7:4987] HI all Have anyone troubleshooted PPP TI before? it is leased line and ppp encapsulation.
