Dear all,

I have an error DHLC card, its lamp turn red steadly and all of phones connected to it are disfunction. Can anybody tell me whats the problem and how to fix it?

Check error log using maintenance console.

if it is a tda 100 / 200 system the card fuse has blown it will have to be sent back for repair or be replaced

If a replacement card is ok, then original is faulty. I know this sounds obvious but I work on repairing these systems and cards.
