CMOS
– Concatenation of any, not necessarily consecutive, time slots to superchannels
independently for receive and transmit direction.
– Support of H0, H11, H12 ISDN-channels.
– Subchanneling on each time slot possible.
• Bit Processor Functions (adjustable for each channel)
– HDLC Protocol
– Automatic flag detection and transmission
– Shared opening and closing flag
– Detection of interframe-time-fill change, generation of
interframe-time-fill ‘1’s or flags
– Zero bit insertion
– Flag stuffing and flag adjustment for rate adaption
– CRC generation and checking (16 or 32 bits)
– Transparent CRC option per channel and/or per message
– Error detection (abort, long frame, CRC error, 2 categories
of short frames, non-octet frame content)
– Special short frame mode to allow reception of ‘frames’ with a least on byte
length
– ABORT/IDLE generation
