Never connect the power supply of the HFC-4S / 8S to 5 V!
4 (HFC-4S) resp. 8 (HFC-8S) integrated S/T interfaces
single chip ISDN-S/T controllers with HDLC support for all B- and D-channels
full I.430 S/T ISDN support in TE and NT mode
Independent read and write HDLC channels for 8 (HFC-4S) resp. 16 (HFC-8S) ISDN
B-channels and 4 (HFC-4S) resp. 8 (HFC-8S) ISDN D-channels
B-channel transparent mode independently selectable
up to 32 FIFOs for transmit and for receive data, FIFO sizes are configurable
each FIFO can be assigned to an arbitrary HFC-channel, moreover each HFC-channel
can be assigned to a S/T-channel of one S/T interface or to a time slot of the PCM
interface
