is called an A/D converter. The device that converts digital signals into their analog form (if
required), is called a D/A Converter.
required), is called a D/A Converter.
Analog Transmission
The transmission of a continuously varying signal. For example, in the transmission of speech
the magnitude of the signal at any instant in the transmission path is proportional to the
magnitude of the original input. This type of transmission is distinct from digital transmission in
which the original input is encoded (for example, CODEC) and the resulting line signal is in
digital form.

Answering Point
A device to which an incoming call is directed. It usually consists of an industry-standard
telephone or an attendant console. Under certain conditions an answering point may be a hunt
group, a trunk, an ACD path or a device such as a night bell, an answering machine or a
recorder/announcer machine.

Application Processor
A processor containing one or more application programs which meet a customer’s particular
needs; for example, a hospital, a governmental agency or a university environment. The
processor is usually arranged to be accessed directly by an input/output device. However, it
can be connected to the SX-200 EL/ML system by means of suitable interface arrangements,
and therefore be capable of access by suitable input/output devices which are also connected
to the SX-200 EL/ML system.

Associated Data Line
A DTE connection to an SX-200 EL/ML system by means of a dataset which has an associated
telephone set. The user sets up a data call by dialing an access code and destination dataset
number.
telephone set. The user sets up a data call by dialing an access code and destination dataset
number.
Asynchronous Mode
In asynchronous data transmission the time between bytes (characters) is indeterminate and
depends upon external factors. The transmitted data has its own start and stop elements, and
thus controls the receiving device. See also Synchronous Mode, page 241.

Attendant
The person assigned to handle calls appearing at the attendant console.
Authorized Access Codes
The SX-200 EL/ML system can only be accessed for programming, maintenance or
administration purposes by first entering an authorized access code (user name and password).
