asterisk users - May 2004 - D-Channel on span 1 up/down + frame slips with zaptelBRI

I have installed two HFC PCI A-cards running zaphfc from bristuff-0.0.2,
which seems to work quite fine, but I continously receive the messages
"D-Channel on span 1 up" followed by "D-Channel on span 1
down" with a few
seconds interval. Why is that? Bri intense debug log and configuration
files below.

I don't need ztdummy or zaprtc, do I? I get some frame slips as well, but
zaphfc should be enough to get the timing?

Regards,
Tobias

Hej Tobias.

By judging from Your domain and lastname I guess You live in vikingland ;)
As I have learned from kapejod, Telia (swedish telco) tries to power 
down the D-Channel  and then the driver wakes up the channel again with 
a poll.

So it's just normal

Ha en underbar dag!
