Works fine with Junghanns' cards.

One simple thing for you to test: set one port in TE mode and one port
in NT mode (move all 5 jumbers of that port to the other position to get
it into NT mode). Then try to make a loopback connection (using a
standard ethernet cable). Here you control both ends and thus there are
less configuration pains.

One thing that could be wrong is if both sides do not agree on the line
settings.

Where do you connect to? What do you have on zaptel.conf ? On
zapata.conf?
