(Automatic Line Selection) The programmed order in which
the system makes outside lines available to a user.
See AMI.
(Alternate mark inversion) A line coding format in which a
binary 1 is represented by a positive or negative pulse, a
binary 0 is represented by no line signal, and subsequent
binary 1s must alternate in polarity; otherwise, a bipolar
violation occurs. AMI is used in the DS1 interface.
A 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) The 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. INFO-2
(Information Forwarding-2) is AT&T’s ANI service.
Software and/or hardware that adds functional capabilities
to the communications system. For example, AUDIX Voice
Power is an IS II/III application that provides a variety of
voice messaging system services.
(Automatic Route Selection) A communications system
feature that routes calls on outside trunks according to the
number dialed and trunk availability.
American Society of Composers, Artists, and Producers.
(AT&T Switched Network) AT&T telecommunications
services provided through an Integrated Digital Services
Network Primary Rate Interface (ISDN-PRI) trunk, Accunet
switched digital service, Megacom WATS, Megacom 800,
Software Defined Network (SDN), MultiQuest, and Shared
Access for Switch Services (SASS).
A method of transmitting a short bit stream 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.
See ASN.
A voice-processing application, part of IS II/III, that provides
Automated Attendant, Call Answer, Information Service,
Message Drop, Voice Mail, and, optionally, FAX Attendant
System for use with the communications system.
