							FEATURES AND SERVICES
FEATURES AND SERVICES
Introduction
This section describes the System Features, Station Features, Network Features, Data
Features, and Attendant Features of AT&T System 25. It also covers certain services that
support and implement the features; included in this category are the digital tape unit, the
dial plan, system administration, and system maintenance. A general discussion of data
topics is also provided.
The feature descriptions are arranged in alphabetical order, regardless of the feature group
to which they belong.Information for each feature is presented under one or more of the
following five subheadings:Description,
Considerations, Interactions, Administration
Requirements, and Hardware Requirements.Headings that are not applicable are omitted.
l Description
Defines the feature, describes what it does for the user, and how it is used.
l Considerations
Discusses the applications and benefits of the feature, followed by feature
parameters and factors to be considered when the feature is used.
l Interactions
Lists and briefly describes other features that can affect the feature being described.
Interacting features are those that:
— Depend on each other—One of the features must be provided if the other
one is.
— Cannot coexist—One of the features cannot be provided if the other one is.
— Affect each other—The operation of one feature modifies, or is modified by,
the operation of the other.
— Enhance each other—The features, in combination, provide improved service
to the user.
l Administration Requirements
States whether or not administration is required and lists items requiring
administration.
l Hardware Requirements
Lists any additional hardware needed to use the feature.

							FEATURES AND SERVICES
Symbols Used in Illustrations
Many feature descriptions in this section contain illustrations of equipment and connections.
In the connection figures, modular jacks are shown as triangles; 25-pair cable connectors are
indicated by shaded blocks.Unterminated wiring that requires cutdown or other termination
does not have symbol designations.The 103A Connecting Block is a typical modular wall
jack that provides cutdown connections for building (station) wiring.
Feature Tables
Tables 2-A through 2-E list all the features of System 25. Each feature is specified as
Standard or Optional.
Standard features are built into the system. They are always provided but may require
administration to make them operational.Standard features are identified in the feature
tables by the letter S.
Optional features require both administration and additional equipment. Music-On-Hold is an
example. Optional features are identified by the letter O.
Bracketed words in the tables are the standard labels of the associated feature buttons.
These labels are also used in the feature descriptions.

							FEATURES AND SERVICES
Station Features
The many Station Features (Table 2-B) available allow individual user needs to be met. As
these needs change, assigned features can also be changed. Station Features provide many
important services that help save time and make calling more convenient.

							FEATURES AND SERVICES
Attendant Features
Attendant Features (Table 2-E) are available to the attendant using the Direct Trunk
Attendant Console (DTAC) or the Switched Loop Attendant Console (SLAC) and the optional
Direct Extension Selector Console. In addition, most multiline voice terminal station features
are available to the attendant.

							FEATURES AND SERVICES
Account Code Entry, Forced
Description
This feature forces selected station users to enter account codes before dialing certain calls
out of System 25.Users at stations that have Forced Account Code Entry (FACE) are
required to enter account codes either for all outgoing calls or for just “dial 0 or 1” toll calls.
The code entries appear in the ACCOUNT field of the SMDR records.
To place a FACE-restricted call, the user must dial the Account Code Entry access code V 0
followed by an account code before dialing the rest of the call. The account code entry is
terminated when the number of digits entered equals the number administered for system
account codes or when # is entered.The user hears second dial tone after the code is
entered and can then dial the necessary access codes and other numbers to reach the
destination.
If the user makes an error while entering the account code, the procedure can be corrected
by dialing V 0 followed by the correct account code.
The user receives reorder tone when an account code is required on a call but not entered.
Considerations
FACE ensures that specified outgoing calls include information (project, client, department,
etc.) to be used for accounting and billing purposes.
The voice terminal user cannot use the Account Code Entry feature button for forced entry.
This button is used with the Optional Account Code Entry feature only.
An account code entry cannot be forced for the following types of calls:
l Personal Line calls
l Direct Facility Access calls
l Remote Access
l Calls to 911 and the three ARS-administered emergency numbers, when using ARS.
FACE requirements apply to calls using these facilities and features:
l Repertory Dialing
l Personal/System Speed Dialing
l ARS (nonemergency) and pooled facility access codes
l Trunk calls using Conference or Transfer
2-8 
						

							Account Code Entry, Forced
The system does not check the validity of account codes. It checks only for the proper
number of digits or the code terminator #.
Calls that do not require FACE can still be assigned an account code, as in previous releases
of System 25.Refer to the “Account Code Entry, Optional” feature description in this
manual for the procedures.
Interactions
The following features interact with Forced Account Code Entry.
Bridging of System Access Buttons:Calls made from Bridged Access (BA) buttons on a
bridging station follow the FACE restrictions of the bridging station, not of the associated
principal station.
Call Accountability: The account code entry may be made before or after the Call
Accountability entry. Dial tone is returned to the user after either entry.
Callback Queuing: An account code entered before queuing is saved for SMDR.
Conference: Calls can be conference in both directions between a FACE-restricted station
and a non-FACE station.
Display: When a user activates the Forced Account Code Entry feature by dialing V 0, the
system displays the prompt ACCT?. As the user enters the account code, the digits are
displayed to the right of the prompt.If the number of digits exceeds 9, the system
automatically scrolls to Screen 2; the continuation character “-” and the remaining digits
appear on Screen 2.
The prompt and digits remain displayed until one of the following occurs:
— The user enters either “#” or the administered number of code digits.
— The user restarts the Account Code Entry feature by dialing V 0 to correct an
erroneous entry.
— The system time-out for Account Code Entry is reached.
— The user selects another button that overwrites the display.
Forwarding: Stations with FACE administered for all calls cannot forward calls to any
outside numbers. Stations with FACE administered for “dial 0 or 1” calls can forward calls
to any outside number except for “dial 0 or 1” numbers.
Intercept Treatment with Reorder Tone:The user receives reorder tone when an account
code is required on a call but is not entered.
Last Number Dialed: The access code V 0 and the account code are not stored by this
feature.
