Well, no. I didn't scrutinize the CO too much because the DX-80 displays strange behavior. For example, I used a DET to call the AA from an outside line, dialed a mailbox with 3 way xfer to a cellphone, and the DET lit like a christmas tree prior to disconnecting the call. The CO is a small company that runs fiber to every premise, and there is a NID that breaks it out to analog ports.
