							Line Status and I-Use Indications
Interactions
The following features interact with Line Status and I-Use Indications.
Attendant Console, Direct Trunk: When a line that appears at both the attendant position
and a multiline voice terminal is placed on hold by the terminal user, the green status LED
winks at the terminal but lights steadily on the Attendant Console. When the line is placed
on hold by the attendant, the green status LED winks on the console and on voice terminals
on which it appears.
Bridging of System Access Buttons: The meanings of green line status and red I-use
indications on Bridged Access button are the same as for System Access buttons.
Personal Lines: Trunk-to-trunk transfers will cause the affected PERS LINE buttons on the
DTAC to wink.

							FEATURES AND SERVICES
Local Display
Description
This feature allows the user of a display-equipped voice terminal to operate the Time/Timer
circuit built into the display module. The voice terminal must be in the “Local Mode” for use
of Local Display. The Timer has Set, Start, Fwd (Forward), Stop, Rev (Reverse), Time/Timer,
and Exit buttons to control the visible clock, calendar, and 60-minute timer displays and an
audible alarm. Some terminals are equipped with a LOCAL button for entering and exiting
Local Mode.
Local Display operation depends on the functional assignment and administration of the
voice terminal:
l General Use Station or Not-Logged-In Direct Group Calling (DGC) Group Member
Station—LOCAL button optional.
When the terminal is idle, Local Mode is automatically on and the clock/calendar
screen is displayed.Any call-handling activity (such as a ringing call or going off-
hook) overrides Local Mode and displays the appropriate Normal Mode data. During
Normal Mode activity, the user can manually return to Local Mode (for example, to
find out what time it is or to time a call) by pressing Time/Timer; to return from this
condition to Normal Mode, the user presses the active call appearance button. When
the call activity ends and the user goes on-hook again, the terminal reverts to Local
Mode.
If the terminal has a LOCAL button, it can be used to turn off Local Mode; during idle
periods in this condition, the screen remains completely blank. To return to Local
Mode, the LOCAL button must be pressed again.
l Logged-In DGC Group Member Station—LOCAL button optional.
At a DGC terminal that is logged into the group, Local Mode is normally off. During
idle periods, the group queue count is displayed, but the user can press LOCAL, if
equipped, or Time/Timer to override the queue count and activate Local Display.
Any change in queue count, or new call-handling activity, returns the terminal to
Normal Mode. When active on a call, the user can go to Local Mode by pressing
Time/Timer and return to Normal Mode by pressing the active call appearance
button.
If the terminal has a LOCAL button, it can be used exit and enter Local Mode.
l Switched Loop Attendant Console (SLAC)—fixed LOCAL button.
At a SLAC, Local Mode is normally off. During idle periods, when no calls are being
handled and the display screen is blank except for the SLAC queue count, the
attendant can press the LOCAL button to override the queue display and enter Local
Mode. If the queue count changes or a call comes in, Local Mode is overridden and
the queue count or incoming call information (plus queue count) appears on the
screen. Initiating a call, or pressing LOCAL again, will also cause the console to exit
Local Mode.

							Local Display
The terminal user can set any of the Local Display functions by performing the following
procedure while not active on a call:
1.If the clock/calendar screen is not already being displayed, press LOCAL (or
Time/Timer if the terminal has no LOCAL button).
The clock/calendar screen appears on the display
2.    Press Set repeatedly, until the item to be changed flashes.
3.Press Fwd or Rev to change the item’s setting.
4.To change the setting of another item, return to step 2.
5.Press Exit.
The clock/calendar screen appears on the display.
If the alarm clock function is set, the terminal will “beep” at the selected time. This audible
alarm should not be confused with the Attendant System Alarm Indication feature, which
causes the ALARM button LED to flash when system trouble is detected.
To time an event (such as a call), the user performs the following procedure while not active
on a call:
1.If the clock/calendar screen is not already being displayed, press LOCAL (or
Time/Timer if the terminal has no LOCAL button).
The clock/calendar screen appears on the display.
2.    Press Time/Timer.
The timer screen appears on the display.
3.    To start the timer, press Start.
The timer resets to 00:00, then begins timing.
4.To stop the timer, press Stop.
5.    To time another event, return to step 3.
6.    Press Exit.
The clock/calendar screen appears on the display.
Considerations
At SLACs and logged-in DGC terminals, preference is given to queue displays over the
clock/calendar display. This condition can be overridden by pressing LOCAL, if available.

							Manual Signaling
Manual Signaling
Description
This feature allows a user to signal another voice terminal. The user may do this at any
time, whether on-hook or off-hook. In voice terminal user guides, this feature is called
“Signaling.”
Multiline voice terminal users can signal another predesignated multiline voice terminal by
pressing an associated Manual Signaling (SIGNAL) button. A single tone burst is provided at
the signaled terminal.The signaling voice terminal also receives the tone and can use this
feature while in any call state.No LED indication is associated with the Manual Signaling
feature.
When the Manual Signaling feature is used while the called station is ringing on another call,
no audible signal is received by either the signaling or the called voice terminal.
The duration of the single burst of signaling will always be the same, regardless of how long
SIGNAL is pressed. The signal is repeated each time the button

							Message Center-Like Operation (SLAC Only)
Message Center-Like Operation (SLAC Only)
Description
A System 25 Switched Loop Attendant Console (SLAC) can be made to function like a
message center through administration of call type translations. Certain specific types of
calls in the common queue will then be directed only to a console administered as a
message center.This arrangement involves no changes in equipment or in operating
procedures. The message center attendant answers incoming calls of the preselected types
in the normal way.No provision is made for storing messages, a capability often associated
with full service message centers.
Message Center Call Types:
The Message Center receives calls of the following types:
l Returning parked calls that were originally parked from a Selector Console.
l Returning camped-on calls.
l Returning calls that were extended (transferred) from an Attendant Position to a busy
station or a station that does not answer.
l Coverage calls—incoming inside and outside calls (including DID calls) covered by
the common queue when the called party does not answer, is busy, or does not want
to be disturbed (Send All Calls).
l Floating PDCs (FPDCs) not signed in at a station and unassigned DID calls
The type of each incoming Message Center call will be identified by a call type descriptor on
the console’s 16-character display screen. Refer to the earlier Switched Loop Attendant
Console feature description for a list of descriptors.
Console Configurations:
Message Center-like operation applies only when the System 25 has two SLACs. In a one-
console system, all calls are handled at the same position.
In the default condition, a SLAC is a combined Attendant Position/Message Center. It can
receive any type of call. In a one-console system, there is no division between attendant and
message center functions.
A dedicated Message Center is a console that is administered to receive only the specified
incoming call types.Dial 0 calls (attendant-seeking calls from inside the system) are not
directed to a Message Center, but the console has a unique PDC number that callers can
use to reach the attendant.
A dedicated Attendant Position is a console that is administered to answer all of the calls not
handled by the Message Center.
2-225 
						

							FEATURES AND SERVICES
Message Center capability canbe supported in any of the following two-console
configurations:
l One dedicated Attendant Position and one dedicated Message Center. A call
extended by the Attendant Position to a station that does not answer or is busy
returns to the Message Center.
l One dedicated Attendant Position and one combined Attendant Position/Message
Center; the Attendant at the combined position also functions as the Message Center
operator for the entire system.A call extended by either Attendant to a station that
does not answer or is busy returns to the Message Center.
l Two combined Attendant Position/Message Centers; the Attendants at each
combined position also function as Message Center operators. The special call types
answered by Message Centers can be divided between the two consoles, or both
consoles can answer all types. A call extended by either Attendant to a station that
does not answer or in busy returns to the Message Center specified in translation.
Three return options are provided: to the 1st attendant, to the 2nd attendant, or to
either attendant.
Interactions
All System 25 console features are accessible at a Message Center. Operating procedures
are exactly the same as those at a standard Attendant Position. The BIS and HFAI features
can be used to answer Message Center calls.
An auxiliary Direct Extension Selector Console can be used with a Message Center.
Outgoing calling, from the Basic Console or the Selector Console, is not affected by
Message Center administration.
Administration Requirements
A new item in administration allows selection of an alternative set of call type defaults,
making one of the attendant positions a “message center”.These defaults may be modified
for individual call types, if desired, to tailor the message center-like operation for different
locations. For administration purposes, the Message Center call types are divided into four
groups: (1) Calls to FPDCs that are not signed in anywhere; (2) Unassigned DID calls; (3)
Coverage calls; (4) Returning calls.
With the standard (ie, non-message center) defaults, each of these groups is translated to be
directed to all consoles. When both positions are combined Attendant/Message Center
consoles, administration can direct specific types to one or both consoles.
Message Center calls are held in the same common queue as any other attendant-seeking
calls before being directed to the console.

							Messaging Services
Messaging
Description
These services
Services
include features that light a Message LED to indicate that another station or
the attendant) has a message for the user.
The Messaging Services provide light activation/deactivation only. Users must call the
sender to receive their messages.
The system supports four types of Message Waiting services:
l Attendant Message Waiting
l Coverage Message Waiting
l Dial Access to Message Waiting Indicators
l Station-to-Station Message Waiting
It also provides interface with the AT&T VOICE POWER Voice Message System.
Attendant Message Waiting
The Attendant can turn on (and turn off) the Message LED at other voice terminals. When
this indicator is lighted, users call the attendant for messages. The LED on multiline
terminals may be turned off by the user (by pressing MESSAGE), by the attendant, or by
another station with the Dial Access to Message Waiting Indicators feature. The Message
LED on single-line terminals can be turned on or off by the attendant or by the user with the
Dial Access feature.
Refer to the “Attendant Message Waiting” feature description for additional information.
Coverage Message Waiting
Allows a user providing Individual Coverage to control the Message LED on a covered (or
bridged) voice terminal.(This feature also allows a bridging station user in a
Principal/Bridging arrangement to control the principal’s Message LED using the procedures
described here.) A Coverage Message button (COVER MSG) at the covering station is used
to display and control the status of the covered user’s Message LED. The state of the
COVER MSG LED reflects the state of the covered station’s Message LED. The covering
user can turn on or off (toggle) the covered party’s Message LED at any time during a
coverage or bridged call by pressing COVER MSG. To turn on the covered user’s Message
LED when not on a coverage or bridged call, the covering user may go off-hook on a System
Access button, press COVER MSG and then dial the covered user. The covered station’s
Message LED turns on if off and stays on if already on.If the covering station then presses
COVER MSG a second time before hanging up, the Message LED will turn Off.
A covered party must dial the covering party to retrieve messages. Multiline voice terminal
users can press MESSAGE to turn Off their Message LED. Message indicators on single-
line voice terminals can be controlled by the user, the covering party, or the attendant, by
using the Dial Access feature.
2-227 
						

							FEATURES AND SERVICES
If a user tries to turn on the Message LED at a voice terminal for which the user does not
provide Individual Coverage, Reorder Tone is received.
Refer to the “Coverage, Individual” feature description for additional information.
Dial Access to Message Waiting Indicators
This service allows users to turn on or off the built-in Message LED (or Z3A Message
Waiting Indicator adjunct) of any voice terminal in the system (including their own). Access is
by way of dial codes.The service does not apply to the feature buttons/LEDs administered
for Station-to-Station Message Waiting.
Refer to the “Dial Access to Message Waiting Indicators”feature description for additional
information.
Station-To-Station Message Waiting
Multiline voice terminals can be assigned (paired) Message Waiting (MSG WAIT) buttons with
associated status LEDs. When this indicator is lighted, the user calls the other user for
messages. The MSG WAIT LED can be controlled by the two associated terminals only;
either user can toggle the state of both LEDs (e.g., both LEDs go On or Off together) at any
time, whether on-hook or off-hook.
Refer to the“Station-To-Station Message Waiting”feature description for additional
information.
Considerations
The Attendant and Coverage Message Waiting features light the same “basic” Message
indicator on each set. The Station-To-Station feature may be assigned to programmable
(MSG WAIT) buttons between two sets; it lights the LED next to the button.
Administration Requirements
Attendant Position (Voice Terminal) Port:
l Assign ATT MSG button (defaulted).
Voice Terminal Port:
l Individual Coverage Message Waiting -assign Coverage Message (COVER-MSG)
button.
l Assign Individual Coverage (COVER-IND) between sets.
l Station-To-Station Message Waiting -assign paired Station Message Waiting (MSG
WAIT) buttons. Two (multiline) terminals must share this feature.
