h1. CologneChip HFC
This is a seriels of generic ISDN adapters with CologneChip HFC chipsets:
* HFC-E1 (single-port E1 PCI), datasheet see attachment:hfc-e1.pdf PCI)
* HFC-S (single-port BRI PCI)
* HFC-4S (quad-port BRI PCI) + HFC-8S (octal-port BRI PCI), datasheet see attachment:hfc-8s-4s.pdf
* HFC-USB (singel-port USB)
These boards are typically all supported by [[mISDN]], and some by [[DAHDI]]

h2. 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:]].
