Features

The HFC-S PCI is an ISDN S/T HDLC basic rate controller for so called „passive“ ISDN PC cards with

integrated S/T interface and PCM30 highway interface. It is the first all in one solution for a PCI ISDN

PC-card world wide with power management and Windows 98 support.

A 32Kbyte memory window of the PC is used for the deep FIFOs. Also an industrial standard serial

interface for telecom peripheral ICs is implemented. Codecs are normally connected to this interface.
