[asterisk-users] Problems with zaptel and HFC-S PCI card

[Jaap Winius]

Hi list,

Just thought I'd let you know that the problems outlined in my  
previous post apparently had to do with a bad card. After swapping it  
out for another one
the messages went away.

Of course, I still have some problems. For instance, there's this  
error that keeps appearing in my syslog and kern.log:

    zaphfc: empty HDLC frame or bad CRC received

Any idea how to get rid of it?

Thanks,

Jaap
