HI,


We are getting a lot of LCV and PCV errors on our 2650XM router. Vendor has checked the cabling and our cables also has been checked for errors but everything seems to be fine.

We are running IOS code-12.3(13a) on our router.

Hi!


I'm going to assume this is a T1 link. First thing you should do is a hard loop test to determine if your controller is running clean. You can find the procedure here: http://www.cisco.com/en/US/tech/tk713/tk628/technologies_tech_note09186a00800a754b.shtml .


If this runs clean, then loop the line at the CSU/DSU, and re-run. If it still runs clean, then have your provider test the line.

We have tested the controller card as well as cabling on our side, vendor also tested teh circuit from thier side and they updated that theyare running clean too.

We are not sure, where the problem lies now.
