							GLOSSARY
GLOSSARY
The following is a
list of definitions of terms used in System 25
documentation.
Administer
To access and change the parameters associated with the services
or features of the system.
Analog Data Endpoint
Data endpoints connected to the system by (built-in or stand-alone)
modems.
They do not require
the use of data modules
(Asynchronous Data Units) and are addressed like a voice terminal,
by Personal Dial Code (PDC). These endpoints connect to Tip/Ring
circuit pack ports.
Analog Voice Terminals
See Single-Line Voice Terminals.
Appearance
See Call Appearance.
Asynchronous Data Transmission
A scheme for transmitting data where each character is preceded by
a start bit and followed by a stop bit, thus permitting data elements
to occur at irregular intervals. This type of transmission is
advantageous when transmission is irregular (such as when
characters are typed from a keyboard).
Asynchronous Data Unit (ADU)
A Data Communications Equipment (DCE) device that allows direct
connection between RS-232C equipment and the digital switch
through ports on the TN726 Data Line circuit pack.
G-1 
						

							Attendant
The operator of the attendant console.
Attendant Console
l Direct Trunk Console: An electronic call-handling position with
pushbutton control. Used by attendants to answer and place calls
and to manage and monitor some system operations.
l Direct Extension Selector (DXS) Console: Provides the attendant
with a visual indication of the status of stations. Also allows the
attendant to extend incoming calls to stations through button
access rather than by dialing.
Auxiliary Equipment
l  Dictation Equipment
lDelay Announcement Devices
lExternal Alerting Devices (external alerts)
lMusic-on-Hold Equipment
l Paging Equipment.
Auxiliary Trunk
A trunk circuit used to connect auxiliary equipment to the switch.
Only dictation and paging equipment may be connected through an
auxiliary trunk.
Bit (Binary Digit)
One unit of information in binary notation (having two possible states
or values, 0 or 1).
Bridge (Bridging)
The sharing of the same extension by two or more voice terminals.
G-2 
						

							GLOSSARY
Buffer
A circuit or component that isolates one electrical circuit from
another. Typically, a buffer holds data from one circuit or process
until another circuit or process is ready to accept the data.
Bus
A multiconductor electrical path used to transfer information over a
common connection from any of several sources to any of several
destinations.
Bus, Time-Division Multiplex
See Time-Division Multiplex Bus.
Call Appearance
A button on a multiline voice terminal at which a call seems to
appear.Calls may be received, originated, and held at an
appearance.
System Access,Personal Lines, Direct Extension
Selection, and Pooled Facilities are examples of call appearances.
Software makes it seem to the terminal user that a line actually is
terminated at the button.
Call Appearance, Voice Terminal
A button labeled with an extension number or line number used to
place outgoing calls, receive incoming calls, or hold calls. Two
light-emitting diodes (LEDs) next to the button show the status of the
call appearance or status of the call.
CCS (Hundred Call Seconds)
A traffic-measuring unit
traffic-handling devices
interruption represents a
Erlang).
Central Officethat
A
loadexpresses the load of one or more
device used for 1 hour without
of 36 CCS, which equals 1 erlang (see
The location housing telephone switching equipment that provides
local telephone service and access to toll facilities for long-distance
calling.
G-3 
						

							GLOSSARY
Central Office Codes
The first three digits of a 7-digit public network telephone number.
These codes are numbered from 200 through 999 and are
sometimes referred to as NNXS.
Central Office Trunk
A telecommunications channel that provides access from the system
to the public network through the local central office (CO).
Channel
A communications path for transmitting voice and data.
Class of Service (COS)
Parameters used to define voice terminal, data, and trunk port
capabilities and restrictions.
Common Control Switching Arrangement (CCSA)
A private telecommunications network using dedicated trunks and a
shared switching center for interconnecting company locations.
Confirmation Tone
Three short bursts of tone followed by silence; indicates that the
feature has been activated, deactivated, or canceled.
Console
See Attendant Console.
Coverage Call
A call that is redirected from the called station to an alternate
answering position.
Coverage Path
The order in which calls are redirected to alternate answering
positions.
G-4 
						

							GLOSSARY
Covering User
The person at an alternate answering position who answers a
redirected call.
Data Channel
A communications path between two points used to transmit digital
signals.
Data Communications Equipment (DCE)
Refers to a specific RS-232C interface connector configuration. The
DCE devices are designed to interface directly (pin-for-pin) to Data
Terminal Equipment (DTE).The transmit and receive pins are
reversed from that of a DTE interface. A modem is an example of a
DCE device.
Data Dial Code (DDC)
The extension number of a digital data endpoint.
Data Endpoint
Two general groups:those having a DTE-type interface, which
encompasses almost all of the data terminal devices, and those
having a DCE interface, which are primarily modems. It should be
noted that within each category, control interfaces may vary. Refer
to Analog Data Endpoint and Digital Data Endpoints for additional
information.
Data Module
A DCE device providing a standard interface between data
equipment and a TN726 Data Line CP port on the switch. Only ADU
Models Z3A1, Z3A2, Z3A4, and Z3A5 are supported.
Data Terminal Equipment (DTE)
DTE refers to a specific RS-232C connector termination designed to
connect directly to a DCE-type connection. Typically associated with
video display terminals, printers, and computers that either originate
or terminate a data transmission path.
G-5 
						

							GLOSSARY
Delay-Dial Tie Trunk
Digital
DigitalAfter a request for service (called a seizure) is detected on an
incoming trunk, the system sends a momentary signal followed by a
steady tone over the trunk. This informs the calling party that dialing
can start. This type of trunk allows dialing directly into the system;
that is, the digits are received as they are dialed.
Data Endpoints
In System 25, digital data endpoints include any DTE or DCE with an
RS-232C interface to the switch connected through Asynchronous
Data Units.
Tape Unit (DTU)
The RS-232C
translations.peripheral DTE used to store and reload system
Direct Extension Selector (DXS) Console
An option at the attendant console that allows an attendant direct
access to voice terminals by pressing a Group Select button and a
DXS button.
Direct Group Call (DGC)
An incoming call that arrives on a loop-start, ground-start, or tie
trunk and is routed to a predetermined group of stations (for
example, sales department and service department).
Direct Inward Dialing (DID)
A service whereby the called extension (station) number is
transmitted to a PBX by the central office (CO) and incoming calls
are routed directly to the called station, bypassing the attendant.
DSn
Generally, Digital Signal (DS) level n refers to the logical organization
or division of the bandwith available on T carriers. DSO is a single
64 Kbps channel. Twenty-four DS0 channels combine to form a DS1
channel.Four DS1 channels combine to form a DS2 channel.
Twenty-eight DS1 channels combine to form a DS3 channel.
G-6 
						

							GLOSSARY
Dual-Tone Multifrequency (DTMF)
Industry terminology for touch-tone calling.
Emergency Transfer Unit (ETU)
Provides direct connection of designated Power Failure Transfer
(PFT) registered voice terminals to the CO during a power failure or
other service interruption.
Erlang
A traffic measuring unit that expresses the load of one or more
traffic-generating devices (36 CCS equals 1 erlang—see CCS
[Hundred Call Seconds]).
Extension Number
A 1- through 4-digit number assigned to each voice terminal and
data endpoint in the system. Also see “Personal Dial Code.”
External Call
A connection between a system user and a party on the public
telephone network or on a tie trunk. Also referred to as an outside
call.
Facility (Physical)
A transmission channel to another switching system (a Central
Office, for example). By application, examples are:
l CO Trunks
l FX Trunks
l WATS Trunks
l OCC Trunks
l Tie Trunks
l DS1 Tie Trunks.
