#### Supported encodings/checksums:
- BPTC 196/96
- CRC 9/16/32
- Hamming
- Trellis
- Golay 20/8/7
- AMBE (conversion from 72 to 49 bit and vise-versa)
- Quadratic residue (QR) 16/7/6
- Reed-Solomon 12/9
#### Supported IP features:
- UDP/IP4 over dmr (plain)
- UDP/IP4 over dmr (DMR Standart header compression)
- UDP/IP4 over dmr (Advantage header compression)
#### Supported DMR blocks:
- DataHeader (Unified, Response, Confirmed, Unconfirmed, Proprietary, ProprietaryCompressed)
- CSBK (CallAlertACK, CallEmergency, Preamble)
- Rate 1/2 and 3/4 data
- DataBlock with CRC32 (encapsulates IP packets)
