(Automatic Line Selection) Programmed order in which
the system makes outside lines available to a user.
Numbering of extension ranges, remote access codes, or
other system components that causes conflicts in private
network operations. These numbers can be unique and
still be ambiguous. For example, Extension 441 is
different from Extension 4410. However, for UDP routing
purposes, the two numbers are ambiguous and a call
intended for Extension 4410 is misrouted on the first three
digits sent, to Extension 441. See also unambiguous
numbering .
(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.
See modem data station.
Mode of transmission in which information is represented
in continuously variable physical quantities, such as
amplitude, frequency, phase, or resistance. See also
digital transmission .
(Automatic Number Identification) Process of
automatically 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.
Software and/or hardware that adds functional capabilities
to the system. For example, MERLIN Identifier is an
application that provides caller identification information (if
available in the local area or jurisdiction).
(Automatic Route Selection) System feature that routes
calls on outside facilities according to the number dialed
and line/trunk availability. To initiate ARS, the user dials a
dial-out code , also called an "ARS access code."
