Functions
The HFC-E1 is a HDLC B- and D-channel controller with integrated E1 (S2M) interface.
It can be used for ISDN primary rate lines. All channels are served
fully duplex by deep FIFOs. Also implemented is a PCM128/PCM64/PCM30 highway
interface (which is able to connect to many telecom serial busses) and an universal external
bus interface.

single chip ISDN-E1-controller with B- and D-channel HDLC support
-
integrated E1 (S2M) interface
-
full I.431 ITU compliant E1 (S2M) ISDN support in LT and NT mode
-
32 independent read and write HDLC-channels
for e.g. 30 ISDN B-channels, 1 ISDN D-channel and 1 timeslot on the PCM interface
-
B-channel transparent mode independently selectable
-
up to 64 FIFOs; FIFO-size configurable
-
each FIFO can be assigned to an arbitrary channel of the E1 (S2M) or PCM interface
-
max. 31 HDLC frames (with 128k or 512k external RAM) or 15 HDLC frames (with 32k
built-in RAM) per FIFO
-
1 - 8 Bit processing for subchannels selectable
-
B-channels for higher data rate combinable
-
PCM128 / PCM64 / PCM30 interface configurable to interface MITEL STTM bus (MVIPTM)
or Siemens IOM2TM and Motorola GCITM (bearer slots supported only) for inter-chip connection (e.g. external CODECs)
-
H.100 data rate support
universal external bus interfacce configurable into PCI bus, ISA-PnP, PCMCIA
or microprocessor interface as well as SPI (serial processor interface)
