The D channel HDLC controller operates in transparent mode.
Chracteristics:
- Receive frame address recognition
- Address comparison maskable bit-by-bit
- Flag generation / deletion
- Zero bit insertion/ deletion
- Frame Check Sequence (FCS) generation/ check with CRC_ITU-T
Note
. The LAPD protocol uses the CRC_ITU-T for Frame Check Sequence. The polynominal is X
