The parameters of this line "span=1,1,1,ccs,hdb3,crc4" mainly include almost all the features of your E1 line.
Thus, you have to ensure that all of them are matching your real situation. And don't keep their values default.
Regarding this line. Firstly you should ensure that whether you have crc4 feature. And what about the third parameter "1". In general, it is set to 0, not 1.
i change the third 1 to 0. I also check with my telco and they confirmed i have crc4 active.I had no luck yet. Any other ideas of what could it be?in fact if i remove the crc4 option the card goes on yellow alarm and no longer on green status.
