Try replacing the cable from your E1 port to the Telco equipment. If replacing the cable does not work try re-seating your VWIC.<br>

When the problem happens I notice TIMER_RECOVERY on the layer 2 status and I will do a clear interface serial 2/0:15 and clear controller E1 2/0 which will change the layer 2 status to MULTIPLE_FRAME_ESTABLISHED. But outgoing calls can not go through unless I do a reload of the router.I get the following error when I do a debug isdn q931<br>
