The LFAS error increases by 1 each time i reset the card and goes idle for a few seconds before disabling again.

Would the Loss of Frame Allignment Signal be coming from the curcuit provider?

Have you checked the status of DCH 10 in LD 96, theres no point in checking the status of the Channels until you know the DCH has established.

LD 96

STAT DCH

If this is a previously working circuit, and the DCH is not establishing, your first option should be to contact the service provider.
