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
bipolar violation
occurs. AMI is used in the
DS1
interface.

analog
transmission Mode of transmission in which information is represented in
continuously variable physical quantities, such as
amplitude, frequency, phase, or resistance. See also
digital transmission
.
ANI (Automatic Number Identification) Process of a utomatically
identifying a caller’s billing number and transmitting that
number from the caller’s local central office to another point
on or off the public network.

asynchronous
data transmission A method of transmitting a short bitstream of digital data,
such as printable characters represented by a 7- or 8-
bit
ASCII code. Each string of data bits is preceded by a start
bit and followed by a stop bit, thus permitting data to be
transmitted at irregular intervals. See also
synchronous
data transmission
