Generally, you would get this kind of messages if either the signal level is to low, or distorted. The clock-signal for the RX is regenerated from the RX-signal. Now-a-days, these lowerlevel protocols are (should be) completely handeled by the hw of the board (not sure, don't have one here), not by the system. So system load should be not an issue. Those dl360 are not capable of hosting much power greedy pci-boards, so i would not suspect your psu. You wrote you received before thousand calls without much of a problem. So although ESD-damage of the board can not entirely ruled out, its unlikely. You mention "went into production", Did this imply moving of the system from a testing room into a server-location? Other (longer) cables? Perhaps you can check with your telco wether they receive bad frames coming from you.... hw _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
