PCM Encoding
· A-Law or Mu-Law
PCM (Pulse Code Modulation) is a method for encoding voice as data. In telephony, two methods PCM encoding are
widely used, A-law and Mu-law (also called U-law). Typically Mu-law is used in North America and a few other
locations while A-law by the rest of the world. As well as setting the correct PCM encoding for the region, the A-Law
or Mu-Law setting of an IP Office system when it is first started affects a wide range of regional defaults relating to
line settings and other values.
· For IP400 IP Office systems, each control units was manufactured as either an A-Law variant or a Mu-Law
variant.
· For IP500 and IP500 V2 systems, the encoding default is set by the type of Feature Key installed when the
system is first started.
