I am installing some 2811 router with AIM-ATM-T1 interfaces. When I add the network-clock-participate wic 0, I get am ATM_AIM-5-cell_ALARM_DOWN and the ATM_AIM-5-cell_ALARM_up : Interface [chars] lost cell delineation message. I have check clocking settings and they are right. After moving the T1 and AIM cards around the message stop. This is happening on deferent IOS.
I have this problem too.
