We cannot "support" an electrical problem, because we cannot do anything for you over the phone. V.35 is V.35, we've sold thousands of cards, so what can we do if you are using some hokey converter? Get (rent/borrow/whateva) a V.35 breakout box and look at the signals to make certain you are getting clocks on both transmit and receive. When you run hdlccfg and there is transmit clock present, the processor will begin sending data so you should see transmit data. Its very simple...no clock, no data. All the board wants is clock to send, and it will clock in any data in the presence of receive clock. Dont screw around with the settings, which is why i gave up on you, because you dont know what they do and all you are doing is making the problem more difficult to debug. With a CSU you use external clock, period. Unfortunatly most people in this business dont understand datacomm, and this kind of problem requires skills on your end. If you cant do it, find someone who can. I can't do it on the phone. Dennis To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
