CologneChip HFC

This is a seriels of generic ISDN adapters with CologneChip HFC chipsets:
  • HFC-E1 (single-port E1 PCI), datasheet see hfc-e1.pdf
  • HFC-S/HFC-S+ (single-port BRI PCI), data sheet see hfc-spl.pdf
  • HFC-4S (quad-port BRI PCI) + HFC-8S (octal-port BRI PCI), datasheet see hfc-8s-4s.pdf
  • HFC-USB (singel-port USB), data sheet see HFC-S-USB.pdf

These boards are typically all supported by mISDN, and some by DAHDI

ASS-PCI-ISDN with clock output rework

This no-name HFC-S board has been enhanced with a 2pin header to provide an 8kHz clock output. This highly stable 8kHz clock provided by the public ISDN network could be used as a reference clock to HFC-E1 boards driving cellular base stations in the early days of openbsc.
