OK, I think I know where the problem is - there must be a cableing
problem with the Twinax connectors.
So there is my next question:
Which pin of Y01 is TX+ and TX-?
Which pin of Y02 is RX+ and RX-?
The polarity does not care, you can exchange TX+ with TX- and RX+
with RX-. A simple test for just the correct wire without connection
the BS-11:
- On the cable which goes to Y01 you should be able to see a
signal with an oscilloscop between TX+ and TX-.
- If you connect the two TX lines with the two RX lines (loopback,
polarity does not care), the card should synchronise and the LEDs
should not longer blink. Attention: I have tested this on Windows
only, with a loopback, I can see that the card synchronises, however
I don't know what mISDN does, but I guess it will also synchronise.
If this works, you know that the cable is OK.
Best regards,
Dieter
