Can anyone help?

I try restore to the previous backup but result is the same.
What I see the channel 24 is not in use but in green light. The carrier said layer one is up but cannot up the d-channel.

I discovered that the channel 24 would become not in use, everytime after I type amportal restart.

How could I recover that? I finally need to rebuild the whole system to fix that.
