Trunk Lines on T2 and NDDI not working

[Donkilla7]

Am at a site with A4400 and all my trunk lines are not working. What might be the problem. I had a hard disk crash and replaced it, loaded R 3.0

Check the board, unplug replug, try another board, try same board on other slot. Check line voltages.

do a trkstat cr cp and see if you have a CONNECT2 state.

If not, try to plug a loopback and see the status of the channels.

Thanks. Just didn't want to believe that 5 NDDI boards were faulty. The problem was from the service provider. We were lucky that the PRA is by a fiber link. Had to rplace all the NDDI boards.
