By 'adapter boards' do you mean the RCVR card?

Could possibly be a provisioning issue if nothing else has changed.

Is the new T-1 provisioned exactly the same way the old one was? Does the new carrier have all channels provisioned the same way, or are they provisioned differently for channels 1 thru 8?


Sometimes the thoughts in my head get so bored, they go for a stroll through my mouth. This is rarely a good thing.
