Resource not available - cross connect

[Anonymous]

I had loaded a config to a 3430 and noticed the cross-connect would not take for the frame relay.

I tried to enter the crossconnect t1 1/1 1 Frame-relay 1 and it says resource not available. I tried to enter it in both global config and interface config.

T1 shows present

interface frame-relays are there

I removed al frame-relay reference and shut no shut , downgrade reboot , loaded another config, reseated card, rebooted, reloaded configs, we still could not get cross connect to take.

I also noticed that I am not able to console to the unit, it receives debugs and messages from the router but I am not able to type anything back up to it.

Side note: We had to give the customer a loaner since I haven't been able to reach Adtran tech support in over 24 hrs for this problem.

Not sure what is going on over there but I can no longer recommend Adtran products if we cannot reach tech support.

Can you post the configuration here so we can have a look at it?

Did you create a TDM-group for the T1 first?

interface t1 1/1

  tdm-group 1 timeslots 1-24 speed 64

If so, verify that it isn't already connected elsewhere.

Yes, but I could not create a cross connect within either the fr 1 point-to-point or global config.

I was trying to enter cross-connect 1 t1 1/1 1 frame-relay 1

But it said resources not available.

MY ONLY OPTION was to create interface Fr2 point-to-point

Set that with an lmi ansi

And use cross-connect 1 t1 1/1 1 frame-relay 2

Do you know why would that be? I have done over a hundred of these but this time we had these issues.

The cross-connect commands seem to be kind of a hybrid between interface and global.  I haven't seen that issue before unless either the T1 or FR resource wasn't properly configured.

Does "show connections" list anything tied to FR 1?

I loaded the configuration via GUI from a working unit with only changes to the DLCI and but cross connects would not take.

Had to use FR 2 instead of the typical FR1

We got the customer up and running on the new config so going to move on. I think there were other issues with the unit, we ended up RMA’ing it because the serial port was not functioning either.

Thanks for your help
