Error Correction and Compression
ITU-T Standards
- V.42 Error detection and correction
- V.42 bis Data compression (up to 4:1)
- V.44 Data compression (20 to 120% more than V.42 bis)
- Independent of speed standards (but V.44 only with V.92)
Microcom Standards
- Microcom Network Protocol (MNP)
- Both error correction and compression
- Several levels
- Independent of speed standards
