ATT DEFINITY Communications System Generic 3 Planning And Configuration Instructions Manual

							GLOSSARYaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Interface
A common boundary between two systems or pieces of equipment.
Internal Call
A connection between two users within the system.
ISDN Gateway
An adjunct network that forwards information from the switch to a host for data screen
delivery to agents in an ACD split.
Laaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Link
A transmitter-receiver channel or system that connects two locations.
Loop-Start Trunk
After establishing a connection with the distant switching system for an outgoing call, the
system  waits for a signal on the loop formed by the trunk leads before sending the digits
of the called number.  On incoming calls, the received request for service is sufficient to
cause the call to route to a predetermined destination, normally the system attendant
group.  No digits are received.
Maaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Main/Satellite/Tributary
A main switch provides interconnection, via tie trunks, with one or more subtending
switches, called satellites; all attendant positions for the main/satellite configuration, and
access to and from the public network.  To a user outside the complex, a main/satellite
configuration appears as a single switch,  with a single Listed Directory Number (LDN).  A
tributary is a switch, connected to the main switch via tie trunks, but which has its own
attendant position(s) and its own LDN.
Message Center
An answering service for calls that might otherwise go unanswered; an agent accepts
and stores messages for later retrieval.  (Requires an Applications Processor.)
Message Center Agent
A member of the Message Center Hunt Group who takes and retrieves messages for
voice terminal users.

Modem Pooling
Provides shared-use conversion resources that eliminate the need for a dedicated
modem when a data module accesses, or is accessed by, an analog line or trunk.
Multi-Appearance Voice Terminal
A terminal equipped with several call appearance buttons for the same extension
number.  Allows the user to handle more than one call, on that same extension number,
at the same time.
Multiplexer
A device for simultaneous transmission of two or more signals over a common transmis-
sion medium.
Naaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Network
An arrangement of inter- and/or intra-location circuits designed to perform specific func-
tions.
Paaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Paging Trunk
A telecommunications channel used to access an amplifier for loudspeaker paging.

Private Network
A network used exclusively for handling the telecommunications needs of a particular
customer.

The first three digits of a 7-digit private network number.  These codes are numbered 220
through 999, excluding any codes that have a zero or one as the second digit.

Provides the required interface between the system and an EIA computer or data
terminal.
Property Management System (PMS)
A stand-alone computer which lodging and health services organizations use for services
such as reservations, housekeeping, billing, etc.
Protocol
A set of conventions or rules governing the format and timing of message exchanges to
control data movement and correction of errors.

The network that can be openly accessed by all customers for local or long-distance
calling.
Qaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Queue
An ordered sequence of calls waiting to be processed.
Queuing
The process of holding calls in order of their arrival to await connection to an attendant,
to an answering group, or to an idle trunk. Calls are automatically connected in first-in,
first-out sequence.

							aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaGLOSSARY
Raaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Random Access Memory (RAM)
A storage arrangement whereby information can be retrieved at a speed independent of
the location of the stored information.
Read Only Memory (ROM)
A storage arrangement primarily for information retrieval applications.
Recall Dial Tone
Three short bursts of tone followed by steady dial tone; indicates that the system has
completed some action (such as holding a call) and is ready to accept dialing.
Redirection Criteria
The information administered for each voice terminals coverage path that determines
when an incoming call is redirected to coverage.
Remote Home Numbering Plan Area Code (RHNPA)
A foreign numbering plan area code that is treated as a home area code by the
Automatic  Route Selection feature.  Calls can be allowed or denied based on the area
code and the dialed central office code rather than just the area code.  If  the call is
allowed, the Automatic Route Selection pattern used for the call is determined by these
six digits.
Removable Mass Storage Subsystem (RMSS)
A tape storage device that stores the software information for the system.
Reorder Tone
A fast-busy tone repeated 120 times a minute; indicates that at least one of the facilities,
such as a trunk or a digit transmitter, required for the call was not available at the time
the call was placed.
Saaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Service Profile Identifier (SPID)
A unique number of up to 10 digits, assigned to an Integrated Services Digital Network
(ISDN) terminal, that will be used for terminal identification during level-3 initialization.

7103A).
Software
A set of computer programs that accomplish one or more tasks.
Split
A condition whereby a caller is temporarily separated from a connection with the atten-
dant. This split condition automatically occurs when the attendant, active on a call,
presses the Start button.
