Hi,
I have my router 1760 connected to an Adtran HDSL2 card. The card has the DS1 light flashing green and the alarm is red.
My router serial interface says "Serial0/0 down, line protocol down". With the "Show service-module" command I see that says "Transmitter is sending remote alarm".
According to my Adtran card specification the flashing DS1 means "Error detected on the DS1 interface" but I can't understand which interface. Is it mine or the actual card that is bad?
Can anyone explain me that?
Thanks in advance.
