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 data

See modem data station.

 

station

 

 

analog

Mode of transmission in which information is represented in

transmission

continuously variable physical quantities, such as

 

 

amplitude, frequency, phase, or resistance. See also

 

 

digital transmission.

 

ANI

(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.

 

application

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).

 

ARS

(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.”

 

ASCAP

(American Society of Composers, Artists, and Producers)

ASN

(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, Megacom 800,

 

 

Software Defined Network (SDN), Multiquest, and Shared

 

Access for Switch Services (SASS).

 

asynchronous

A method of transmitting a short bitstream of digital data,

data transmission

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.

 

AT&T Attendant

Application with equipment that connects to one or more

 

tip/ring extension jacks and automatically answers

 

 

incoming calls with a recorded announcement; directs calls

 

in response to touch tones.

 

AT&T Switched

See ASN.

 

Network

 

 

AUDIX Voice

A voice-processing application, part of IS II/III, that provides

Power

Automated Attendant, Call Answer, Information Service,

 

Message Drop, Voice Mail, and, optionally, Fax Attendant

 

System for use with the system.
