That's actually what he has right now, and that's not such a good idea. Digium PRI cards can only take ONE clock and that is the clock for the entire card. He needs to build a proper spanning tree, but it appears that he has done this. The Allstream PRI (only four B channels?!) is the primary timing source, and if the Allstream PRI is down, the card will take timing from the Meridian. I would suggest changing the Meridian clocking to '0' (never sync to this span) and ensure that the Meridian is indeed set to recover clock from the line. (This is the default with Meridians). Short of that, I'd be looking at the system itself, looking for timing errors or overutilized CPU to try and track down the source of hte problem. Generally speaking you do not get echo or shitty call quality from frame slips; you get buzzing and HDLC errors and D channel restarts. -A. He should be slaving to the Allstream PRI _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
