This unit (VSX5000) was working previously but now it appears to not detect the ISDN interface. The interface ISDN lights (green and orange) just flash every 5 secs or so. In the admin/network settings, ISDN does not appear.
Hi Martag. In the absence of any other contributions, I'd say something here is faulty. The Codec only displays the Admin>Network>ISDN settings when it detects the ISDN Q-BRI. Clearly this is not happening. The Q-BRI for the VSX5/6000 is different to the other VSXs. See attached setup guide. I think you should RMA the Q-BRI personally.
