AMI
(alternate mark inversion) Line coding format in which a
binary one is represented by a positive or negative pulse, a
binary zero is represented by no line signal, and
subsequent binary ones must alternate in polarity;
otherwise, a
binary one is represented by a positive or negative pulse, a
binary zero is represented by no line signal, and
subsequent binary ones must alternate in polarity;
otherwise, a
bipolar violation occurs. AMI is used in the
DS1 interface.
