APPENDIX A 
GLOSSARY OF SX-200” DlGEYAL TERMINOLOGY 
A.01 This glossary has been produced to assist Mite1 personnel in 
becoming familiar with the terms used in the SX--ZOO@ DIGITAL 
PABX. It is not intended to be a complete listing, because many of the 
more well known terms in use already exist in various existing speci- 
fications, Mite1 Practices and other similar documents. 
ABH 
See Average Busy Hour 
ABSBH 
See Average Busy Season Busy Hour 
A/D 
See Analog/Digital 
AIOD 
Automatic Identified Outward Dialing 
ASCII 
American Standard Code for Information Interchange. A code in com- 
mon use, which was developed by the American Standards Associ- 
ation, for both synchronous and non-synchronous data transmission 
between DTE’s. Characters consist cf an 8-bit binary code and incor- 
porate parity bits. 
AD% 
See Associated Data Line 
Abbreviated Dialing 
The Abbreviated Dial facility is provided to give users the ability to dial 
abbreviated speed call codes, which substitute for a systemwide list of 
frequently-called numbers- These numbers may be displayed, when 
required, at the attendant console. 
Absorbed Digits 
In certain call processing functions performed by the SX-200@ DIGITAL 
PABX, it may be necessary to suppress the onward transmission of 
certain digits received in a dialed sequence of digits. This digit absorp-

tion is required for applications such as DID calls and ARS purposes. 
See also Digit Modification. 
Account Codes 
Account codes are used with the SMDR facility of the SX-200a DIGI- 
TAL PABX in order to record trunk call details (for example, time and 
date of call, its duration, and the calling and called numbers involvedj, 
against a particular user or group of similar users of the system. 
Verified Account Codes allow restricted access to the system. 
A/D Convertor 
See Analog/Digital 
Analog/Digital (A/D) 
A term frequently used in transmi3sion technology which implies the 
transformation of analog signals (such as normal telephone speech 
signals) into their equivalent digital data signals. The device in general 
use which accomplishes this transformation is termed an A/D Conver- 
tor. The device which accomplishes the conversion of digital signals 
into their analog form (if required), is termed a D/A Convertor. 
Analog Transmission 
Analog transmission is the transmission of a continuously varying 
signal. For example in the transmission of speech, where the mag- 
nitude of the signal at any instant in the transmission path is propor- 
tional to the magnitude of the original input. This type of transmission 
is distinct from digital transmission in which the original input is 
encoded (see Codec, for example), and the resulting line signal is in 
digital form. 
Answering Point 
An Answering Point is a device to which an incoming call is directed. It 
normally consists of a station set, an attendant console or a work- 
station; and under certain conditions an Answering Point may be a 
hunt group, a trunk, 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 to meet the needs of a 
hospital, a governmental agency or a university environment. The pro- 
cessor is usually arranged to be accessed directly by an input/output 
device; but it may, for example, by means of suitable interface ar- 
rangements, be connected to the SX-200@ DIGITAL PABX and be thus 
capable of access by suitable input/output devices which are also 
connected to the SX-200@ DIGITAL PABX.

							Features Description 
Application Program 
See Application Processor. 
Associated Modem Line 
This term refers to a DTE connection, by means of a modem, to an 
SX-200@ DIGITAL PABX and which has an associated telephone station 
set. The telephone set can be used as a standard station set connected 
to the PABX; but has the additional capability of connecting the DTE to 
another DTE, via modem, through the DPABX. This is done by using the 
set in the normal manner and dialing the required digits to obtain the 
data call. 
Asynchronous Mode 
This term refers to data transmission, in which a transmitting device 
sends data in a word-by-word sequence; where the time element 
between each word (characterj is indeterminate and is dependent upon 
external factors. The transmitted data has own start and stop ele- 
ments, and thus controls the receiving device. See also Synchronous 
Mode. 
Attendant 
The term applied to the person assigned to handle calls which appear 
at the attendant console. 
Authorized Access Codes 
Access to the SX-200@ DIGITAL PABX for programming, maintenance 
or administration purposes can be obtained only by first entering an 
authorized access code (username and password). 
Autobaud Detection 
This feature of certain data communication equipment allows it to 
interpret, on the receipt of one or more data characters, the baud rate 
of a transmitting source, and set its own receive circuits to accommo- 
date this baud rate. In the SX-200@ DIGITAL PABX the feature is 
applicable to the MaintenaceKDE port which, during the initial setting 
up procedure, automatically adjusts its baud rate to match that of the 
terminal. 
Automatic Route Selection 
Automatic Route Selection selects the optimum trunk route automati- 
cally when a call is made by a station user. This selection is based on 
many factors, including cost, user priority, the day and time of day. 
Average Busy Hour (ABH) 
A term used in traffic analysis and used to calculate ABSBH. 
Page A-3  
						

							Features Description 
Average Busy Season Busy Hour (ABSBH) 
The hcur calculated to have the highest average business day traffic 
load during the busy season. 
Battery and Ground Pulsing 
A method of signaling used on long lines, in which both wires use 
battery and ground at each end of the circuit. When signaling to the 
remote end of the trunk, the battery and ground connections are 
reversed, becoming opposing potentials at the remote end of the trunk 
and increasing the current supply to the trunk. 
Battery Tone 
See Side Tone. 
Blocking 
The term used to express the condition existing in a switching system 
when the immediate establishment of a call is impossible due to 
insufficient switching connections being available in the system at that 
time. 
The unit used in Traffic Analysis to denote the traffic occupancy of a 
switched circuit in a PABX exchange. One CCS represents 100 call- 
seconds. 
CDE

See Control Over Voice 
CP

Central Processing Unit 
Call Processing 
This is the software package which handles all aspects of the setting 
up of connections within the PBX. 
Page A-4  
						

							Features Description 
Control Over Voice 
This facility is used by the SUPERSET qTM station set to perform most 
of the signaling functions of the set. A 32 kHz carrier signal is modu- 
lated according to the control function, and is transmitted to or from 
the set on the same pair of wires used for the audio connection. The 
carrier frequency lies above the normal audio range of the set, and is 
therefore inaudible to the user. 
Circuit Switch (CS) 
The SX-200@ DIGITAL PABX Circuit Switch provides a 16 X 16 matrix of 
bidirectional switch links, with each link accommodating 32 channels, 
each of which can be used for a voice or data transmission. Through 
the circuit switch, any device may be connected to any other device in 
the system. It is located on the DX Module on the Main Control card. 
Circular Hunting 
See Group Hunting 
Class of Restriction (COR) 
A Class of Restriction controls the access which a station (or a trunk) 
has to trunk circuits. It performs functions similar to toll control and is 
programmable on a station (or trunk) basis. 
Class of Service &OS) 
A Class of Service has a number of different feature options assigned 
to it. This Class of Service may be allotted to one or many stations, 
and enables these stations to have, or be denied, features which are 
available within the SX-200@ DIGITAL PABX. Up to 64 COS’s are avail- 
able which allow a large number of different groups of station users to 
be programmed, each with differing feature characteristics. 
Codec 
The Coder-DECoder is a device used in digital switching and trans- 
mission systems, for coding analog signals (e.g. voice signals) into a 
digital format for onward transmission; and decoding a digital trans- 
mission to recover the original analog signal. 
Codec/Filter 
The Codec/Filter chip used in the SX-200@ DIGITAL PABX consists of a 
Codec, a filter and other elements. It forms part of the peripheral card, 
with the Codec portion performing the necessary A/D and D/A func- 
tions and the filter portion providing low pass filtering for the line 
transmission.
