I've never needed to do a PRi debug on a CIX so I am a bit rusty on what would be needed.

Can you get a version number on the PRi? This could be a case of swapping a PRi card.

Were I on site, I would power down, rerack the card several times and power up. Not likely but possible it could be a poor connection on the PRi card. I've had Partner systems where just pulling the card in and out a few times evidently scraped some oxidation away and the card functioned just fine. I would say this is a low probability but would only take a minute and wouldn't hurt anything.

The other option would be to swap the PRi card. The dealer may or may not have a spare card in stock. I always keep a spare just in case, you never know, but bad Toshiba cards are VERY few and FAR between.

Are you bringing in a PRi from your switch or bringing in a data T-1 and converting it to PRi on-site?
