I know the clocksource says "line" but I was grasping I changed it back to internal and both routers (3845's with NM-1T3/E3 Modules) are exactl;y the same
On my cards I have an "AL" light amber and my "FERF/RAI" light is amber
If I disconnect the cable and place a connector in and loop back the cable at one end my alarm lights go off at the distant end
