Glossary
A
access line
A connection from the customer to the local telephone company that provides access to the public network. Also called local
loop.
account code
A code used to associate incoming and outgoing calls with corresponding accounts, employees, projects, and clients.
Accunet
AT&T's switched digital service for 56-kbps, 64-kbps restricted, and 64-kbps clear circuit-switched data calls.
address
A coded representation of the destination of data or of the data's originating terminal, such as the dialed extension number
assigned to the data terminal. Multiple terminals on one communications line, for example, must each have a unique
address.
adjunct
Optional equipment used with the communications system such as an alerting device that connects to a multiline telephone
or to a station jack.
administration port reassignment
Reassignment of the system programming position to any of the first five station jacks on the first 008 MLX module in the
communications system control unit.
alternate mark inversion (AMI)
A line coding format in which a binary 1
signal, and subsequent binary 1's must
interface.
analog transmission
A mode of transmission in which information is represented in continuously variable physical quantities such as amplitude,
frequency, phase, or resistance. See also digital
application
Software and/or hardware that allows users to perform specific tasks. For example, the Call Management System (CMS) is a
DOS-based application that simulates the actions of a system operator by answering calls and distributing them to individual
telephones.
asynchronous data transmission
A method of transmitting a short bit stream of 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
AT&T Switched Network (ASN)
AT&T telecommunications services provided through an Integrated Digital Services Network Primary Rate Interface (lSDN-
PRI) line or trunk: Accunet® switched digital service, Megacom® WATS, Megacom 800, Software Defined Network (SDN),
MultiQUEST®, and Shared Access for Switch Services (SASS).
AUDIX Voice Power (AVP)
A voice-processing application, part of Integrated Solution II, that provides automated attendant, call answering, voice-mail,
message drop, and information services for use with the communications system.
automatic number identification (ANI)
The process of automatically identifying a caller's billing
office (CO) to another point on or off the public network.
automatic-ringdown tie trunk
See automatic-start tie trunk.
is represented by a positive or negative pulse, a binary 0 is represented by no line
alternate in polarity or there will be a bipolar violation. AMI is used in the DS1
transmission.
