CMOS IC

1.1 Key Features

32-channel HDLC controller with PCI interface:

• Serial PCM core

– Up to 32 independent full-duplex channels

– Serial PCM traffic at 2.048, 4.096, 1.544, 1.536,

3.088, 6.176 or 8.192-Mbit/s

• Dynamic Programmable Channel Allocation

– Compatible with T1/DS1 24-channel and CEPT

32-channel PCM byte format

P-MQFP-160-1

– 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

P-TQFP-176-1

– 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)

– ABORT/IDLE flag generation
