    After a cursory search, I wasn't able to find a manual on Tellabs' web site or elsewhere online. Your best bet for finding out would seem to be contacting Tellabs.

    PMA Alarm (Red indication) will glow when line problem is there
    DMA Alarm (Red Indication) will glow when modem h/w problem

    Hope this information is sufficient for fault finding your modem.

    PMA is showing red led and DMA no indication. Line 1 is indicating green. What would be the problem?
