<DIV><SPAN class=831441008-03062009>without clock connected, the hfcmulti module
will fail. test that to see if the card trys to receive external clock. before
you can use the clock from HFC-S, you must load hfcpci module. note that your E1
card is now card number 1 and not 0.</SPAN></DIV>

<DIV><SPAN class=831441008-03062009>then you need to connect the HFC-S card to
you isdn line. your card must activate interface. therefor a telephony
application is required. but before, you need to see if your E1 card syncs to
your HFC-S card. </SPAN><SPAN class=831441008-03062009>if your clock sync works,
i will write a small application to set your isdn card into PTP mode (for
durable link activation).</SPAN></DIV>
