Functions
The HFC-S PCI / HFC-S PCI A is a HDLC B- and D-channel controller with
integrated S/T interface. It can be used for ISDN basic rate lines. All
channels (2B+D) are served fully duplex by six deep FIFOs. The HFC-S PCI
/ HFC-S PCI A has an integrated PCI bus interface. Also implemented is
a PCM30 highway interface, which is able to connect to many telecom serial
busses.
