Hi all,
Is there a command that displays trunk group frame errors in some detail? I have been using the "List measurements DS-1 Log" to check trunk errors but I would like to verify what is actually causing the error seconds John
 
Do you have a Sync source setup for your DS1 traffic? One of my switches was taking framing errors and discovered that the sync reference screen had not been setup. Do DISPLAY SYNC and it will show two fields at the middle of the screen for primary and secondary sync sources. These should be an active digital trunk. The listing at the bottom of the screen shows all the DS1 boards that the switch thinks are available to use as a sync source. I only had one T-1 connected to this switch and set it's board as the primary source and the frame slips went away.
