Working ISDN prototype board

Posted on Fri 25 February 2011 in XiVO IPBX by xcarcelle

This is great to show the working PCB or the ISDN prototype board connected to our IPBX prototype through the LEB and TDM bus of our SoC (INTEL Tolapai). This PCB shows the 4 T0 ports routed to the CologneChip XHFC-4SU. We have been cabling this PCB in a factory facility close to Paris with good results on the quality of the cabling for 230+ parts on our PCB with 4 layers.
