· A-Law or U-Law
PCM (Pulse Code Modulation) is a method for encoding voice as data. In telephony, two methods of PCM encoding
are widely used, A-Law and U-Law (also called Mu-Law or µ-Law). Typically U-Law is used in North America and a
few other locations while A-Law is used elsewhere. As well as setting the correct PCM encoding for the region, the
A-Law or U-Law setting of a system when it is first started affects a wide range of regional defaults relating to line
settings and other values.
