asterisk users - Jun 2006 - quadBRI in bri_net mode - t3 timer expired

Hi all,

i successfully connected our old PBX to an asterisk server with a
junghanns quadBRI, the quadBRI ports running in bri_cpe_ptmp mode 
connected to the interal PBX ISDN ports.

Now i tried to turn it round as our PBX depends on it for some features
and changed one of the quadBRI ports to bri_net signalling and connected
it to one of the external PBX ISDN ports (how do you name that in telco
jargon?).

The card led goes green (indicates an ISDN link), but nothing happens
when i try to place a call from our PBX using the new connection (no
incoming call on the *-console). 

Instead qozap complains every few seconds

Jun 29 19:39:55 asterisk kernel: qozap: activating layer 1, span 3
Jun 29 19:39:58 asterisk kernel: qozap: t3 timer expired for span 3
Jun 29 19:39:58 asterisk kernel: qozap: not re-activating layer1 span 3
Jun 29 19:39:58 asterisk kernel: qozap: clearing alarms on span 3

What is it trying to tell me? My quadBRI doesn't do any powerfeeding, might
that be a problem?
