							Tone Or Voice Signaling
The system allows intercom calls to be tone signaled or voice signaled as the users
desire; however, the programmer uses system class of service programming procedures
to determine which signaling method the system will employed as the primary method.
Regardless of the programmer’s arrangement, telephone users can take action to use the
alternate method when they need it. See the paragraph titledIntercom Call Progress
Tonesfor a discussion of the intercom signaling tones.
Voice Announce Blocking
This feature allows station users to block voice announced intercom signaling by dialing
a code or pressing a programmable button programmed for that purpose. The
programmable button used to block voice signaling is enabled by station class of service
programming.
K
Key System/Hybrid Configuration
The system can operate as either a key system (KF designation) or as a hybrid system
(MF designation). In the past, this digital telephone system provided a hardware strap
that installers could move to distinguish between hybrid system and key system
operation; however, recent rulings by the FCC have eliminated the need for the hardware
strap. Therefore, whenever the programmer assigns lines to line groups, the system
automatically assumes the hybrid mode.
The KF and MF designations are equipment type categories as stipulated in FCC rules
and regulations, Part 68, and appear as part of the FCC Registration Number on the
equipment label. The installer must report the appropriate registration number to the
telephone company at the time of connection along with other FCC mandated
information. Operationally, the hybrid configuration allows dial access to (automatic
selection of) outgoing lines. The specific system feature that is enabled by the
multifunction (hybrid) configuration isLine Group (Including Dial Access). Since this is
a PBX type feature, it may incur a higher monthly tariff to the telephone company.
L
Last Number Redial
Each station is provided with a last number redial feature. This feature will save 32 digits
of the last outside number dialed. A newly dialed number will always automatically
replace a previously dialed number. Upon command, the system will choose a line and
redial the saved number. The system will first choose the prime line if assigned and idle.
If it is busy or unavailable, the system will choose any line assigned to idle line

							preference. If they are unavailable, the system will chose the last line used at the station.
If it is busy, no further choice is made. No class of service is required.
See also,Redialing.
LCD Messaging
Standard and system-supplied custom display messages can be set by dialing a specific
code at any station. Such messages are to be received and displayed by any LCD
speakerphone that calls the station which set the message. When a message is set, the
intercom light at the setting station will flash to indicate that the feature is active.
See also,Messaging.
LCD Support
The system supports the use of digital telephones having a Liquid Crystal Display
(LCD). The display is capable of providing the station user with a visual presentation of:
call cost, call duration, number dialed, name of called station, name of active feature,
date and time, and programming prompts.
Interactive Button Support
The LCD speakerphone provides the user with three interactive buttons and expanded
LCD displays as a standard feature. The interactive buttons provide the user with quick,
easy access to system features and straightforward button programming without dialing
codes. The expanded displays prompt the telephone user on the operation and progress of
many of the telephone features and provides designations for the interactive buttons.
Since the interactive buttons provide many user features, their immediate functions vary
with the feature. The button functions change to match the feature that the user is
currently operating. At any given time, the current button designations show in the
display window.
Button Query
Station users who have LCD speakerphones can use their interactive buttons to access the
button query feature. With this feature, the station user can cause his or her LCD
speakerphone to show the function of each of its buttons on its display.

							Line Features
Access Denied, Line Access Restriction
The system programmer can deny access to particular lines at certain stations in the
system. A station user cannot select a denied line for use. This feature is programmable
on a per line/per station basis in station class of service programming.
Line Answer From Any Station (Night Mode)
When the attendant programs the system for nighttime operation using the night transfer
of ringing feature, the line answer from any station feature is made active. With this
feature, a user can dial an access code over the intercom line to allow him to answer any
ringing outside line. The line need not be ringing at the user’s station for this feature to
be used.
Idle Line Preference
When a station is programmed for idle line preference, it will automatically be connected
to the first assigned idle line. The system can be programmed on a per station basis to
enable idle line preference. When idle line preference is enabled, taking the handset
off-hook will automatically connect the station to any assigned line that is idle and has
been arranged for this feature. The line button will not have to be pressed. If this feature
is used in conjunction with prime line automatic, the user will be given prime line first
when going off-hook. An idle line will be given if the prime line is in use. The station
class of service programming enables this feature on a per station/per line basis.
Line Groups
Outside lines can be grouped together in up to four different groups. Users can program
an autodial button to select a line group or manually enter a dialing code for access to a
line. Grouping can reserve certain lines for certain clusters of stations as in a
tenant-service arrangement. The assignment of line groups frees station buttons normally
used for line selection thus making these buttons available for use with a feature such as
personal DSS/BLF with station-to-station messaging. Lines are placed in line groups
with the line class of service programming.
Line Preselection
A line can be manually selected before lifting the handset (for handsfree dialing) or after
the handset is lifted.

Digital Telephone System Features A – 43 
						

							Line And Line Group Queuing
With the line queuing feature, the station user can take action that will place a station in a
queue where it awaits the availability of a line or line group. The station is automatically
signaled with five-ring bursts when the line is available to it for use. Each station can
queue one line at a time.
Originating Denied
The ability to originate calls on certain lines can be denied at individual stations through
system programming. The originating denied feature is programmed on a per station/per
line basis. Originating denied does not prevent a user from answering a ringing line,
retrieving a held call or receiving a transferred call. Call origination on a line is denied at
a particular station by the station class of service programming.
Prime Line Automatic
If the programmer uses station class of service programming to enable prime line
automatic at a station, the system will automatically select the designated outside line,
intercom line or line group when the user lifts the handset. A user can pre-empt prime
line pickup by preselecting another line before lifting the handset. If the prime line is
ringing, it is automatically answered when the user lifts the handset.
Ringing Line Preference
The system can be programmed on a per station basis to provide ringing line preference
on all lines programmed for ringing at the station. When ringing line preference is
enabled at a station, taking the handset off-hook automatically connects the station to any
outside line that is ringing at it. A line button will not have to be pressed. With ringing
line preference enabled, the telephones denote a ringing line with an orange colored
status light. If a station also has prime line assigned, the prime line will always be
answered first even though it may be the second line to ring. The ability of a particular
station to answer a ringing line without line selection is enabled by the station class of
service programming.

							M
Manual Hold
A button activated feature at each station will place an outside line on hold. When a user
presses the HOLD button while on a call, the system places the call on hold, provides a
distinctive flash rate of the line button indicator, and allows the user to access other
station features. A user at the holding station or at any other station that has access to the
line can retrieve the held call.
See also,Hold.
Meet-Me Answer Page
Any station user can dial a special code number in response to an all-call or zone page
and be connected to the paging party in a private conversation. All-call or zone paging is
provided to the stations through the station class of service programming.
See also,Paging.
Memory Retention Without Batteries
The system memory is electronically protected during AC power failures by an electronic
device sometimes known as a “super cap.” The stored program data will remain in
memory for a minimum of 60 hours provided that the system has been powered
continuously for at least 30 minutes prior to the power failure or disconnection. Also, the
system clock will continue to run and keep time for at least 30 minutes after an AC
power failure or disconnection.
Messaging
Assist Button
This feature allows a station user to program a button to be used for sending a message to
an LCD speakerphone. Once programmed, the station user can press the ASSIST button
at anytime to ring the called station and present a preprogrammed message in the station
display. The user can send a message while on a call without alerting the distant party.
This feature is useful for requesting assistance while engaging on a call. For example, a
customer service representative could request assistance from a supervisor while talking
to a problem caller. The supervisor, upon receiving the tone and noting the display
message, could perform an executive override or service observing action to join the call
or monitor it.
IMI66–107Digital Telephone System
Digital Telephone System Features A – 45 
						

							LCD Messaging
Standard and system-supplied custom display messages can be set by dialing a specific
code at any station. Such messages are to be received and displayed by any LCD
speakerphone that calls the station which set the message. When a message is set, the
intercom light at the setting station will flash to indicate that the feature is active.
Message Waiting
Special feature access codes enable a station user to control the message waiting (MW)
light at other stations in the system. When the message waiting light is turned on at a
station, a call can be automatically placed to the station that turned it on.
Alternately, one station can be designated by COS programming as the central message
desk and can be arranged for exclusive message waiting control. The central message
desk can be used to control message waiting lights and deliver messages to and from all
other stations in the system. The ability of a station to originate a message waiting signal
is enabled by programming action. Station class of service programming provides a
station with the ability to originate a message waiting signal and is used to create a
central message desk. The system defaults the messsage wait originate feature as enabled.
Response Messaging
This feature allows a user to reply in a non-verbal manner to a voice announce or
tone-signaled intercom call or to a subdued off-hook voice announce call if the intercom
caller is using an LCD speakerphone. A station user can press a programmable button in
response to an intercom call and send a message to be shown on the display of the calling
station. Response messages are pre-programmed by the attendant and later stored by
station users at programmable buttons on their individual stations as need dictates.
Station-To-Station Messaging
If a station has a DSS/BLF appearance at another station, a callback message indication
can be left at that station with the DSS/BLF appearance. The user can dial a special code
to turn on the BLF light at the called station that is assigned to the calling station. This
light indicates that a callback is requested. The light is automatically turned off if a
successful callback is made.
If a station number is not programmed for a DSS/BLF appearance at another station,
attempting to place a call back message will cause the central message desk station to
ring. If there is no central message desk assigned, no action will occur.

							Modular Wiring And Jacks 2- Or 4-Conductor Wire System
The system can be completely interconnected by employing industry standard 50-pin
connectors and modular plug/jack combinations. Station wiring is number 22 or 24
gauge, 2-conductor, twisted-pair cable throughout the system. If the installer uses
4-conductor twisted-pair cable, it provides a spare pair for a separate wiring purpose
when needed.
Music Features
Background Music
If the installer connects a customer-provided external music source to the system, the
music from that source will sound through the station loudspeakers after the users turn it
on at their stations. They can adjust the loudness of this background music with the
loudspeaker volume control. The system automatically turns the background music off
during calls. This feature requires no class of service programming.
Music Interface
The common equipment cabinet includes an input jack where the installer can connect a
customer-provided music source.
Music-On-Hold
When an installer connects a customer-provided music source to the system through the
music interface jack, the system supplies that music to the outside lines that users place
on hold.
Music-On-Hold System-Wide Enable/Disable
After the installer has arranged for the system to supply customer-provided music to calls
that users place on hold, the attendant can disable the feature on a system-wide basis.
Mute
Every monitor telephone and speakerphone has a MUTE button which, when pressed,
will mute the handset transmitter (or internal microphone on speakerphones) to prevent
the user’s voice from being heard by the distant party. The MUTE light turns on steady
to indicate a muted condition. The MUTE button provides push-on/push-off operation on
speakerphones. No class of service is required.
IMI66–107Digital Telephone System

							Handsfree Answer Inhibit
The user can use the MUTE button to block all handsfree answerback response. This
arrangement will prevent a station user from monitoring another station site using the
monitoring ability of the voice announce feature. When a user presses the MUTE button,
all handsfree answerback is disabled thus inhibiting any off-site monitoring. The MUTE
light turns on steady to indicate that this feature is active.
N
Night Transfer (Of Ringing)
Night transfer (of ringing) is an attendant-controlled feature that transfers the day ringing
program of all incoming calls to a particular station or stations for off-hour or special
purpose answering. The night transfer mode can only be activated from station 10 or 12.
The individual lines at each station that are to be transferred with this feature are selected
by station class of service programming.
See also,Ringing.
O
On-Hook Dialing
Every monitor and speakerphone provides manual and/or automatic dialing while the
station handset is on-hook. The telephone loudspeaker monitors call progress for
completion. (The handset must be taken off-hook to provide the voice link on
non-speakerphone stations.)
Originating Denied
The ability to originate calls on certain lines can be denied at individual stations through
system programming. The originating denied feature is programmed on a per station/per
line basis. Originating denied does not prevent a user from answering a ringing line,
retrieving a held call or receiving a transferred call. Call origination on a line is denied at
a particular station by the station class of service programming.

							P
Paging
All-Call Paging
All-call paging allows all stations to receive announcements through the station speaker
at once. The system can also send all-call paging to the paging port where it applies it to
the input of an external paging amplifier. Origination of announcements must be via the
station handset. A programmer can arrange each station to receive and/or originate
all-call page. He or she enables the ability to receive and originate all-call paging at a
station through station class of service programming.
External Paging Interface
A dedicated paging port or a spare line port can be interfaced with an external paging
amplifier. The paging amplifier can then be dial-accessed by stations in the system.
DTMF tones can be dialed through the line port to provide zone selection if provided by
the external paging amplifier. The dedicated paging port does not support any “talk-back’
capability even if such a feature is provided by the external equipment. The line class of
service programming arranges a line port for external paging interface. The system
precedes an announcement through the paging port with an alerting tone. Programmers
can choose between an intercom tone or a DTMF signaling tone for this paging alert
tone. They should choose the intercom tone for a soft alert and choose the DTMF tone
for a loud alert.
Meet-Me Answer Page
Any station user can dial a special code number in response to an all-call or zone page
and be connected to the paging party in a private conversation. All-call or zone paging is
provided to the stations through the station class of service programming.
Zone Paging
Zone paging allows groups of stations to receive announcements through the station
speakers. The programming can enable zone paging in up to four different zones. Zone
paging can also be received at the paging port where it can be connected to the input of
an external paging amplifier. The ability of each station to originate and/or receive a page
and the arrangement of the paging into different zones are controlled by station class of
service programming. Zone paging through the paging port is enabled by system class of
service programming.

							PBX/CENTREX/CO Compatible
System features and programmable buttons support the requirements of most PBXs,
Central Offices, and CENTREX systems. Numbers, #‘s,S‘s, programmable pauses, and
flash signals can be made a part of every stored number for access to host system feature
codes.
Personalized Ringing Tone
The system provides a group of distinctive tones for station ringing. A station user can
choose a tone from this group to provide a distinctive ring at his or her telephone. Often,
when several telephones are located close to each other, each user chooses a different
personal ring tone. The system provides six distinctive tones for users to choose from.
See also,Ringing.
Pooled Line Access (Line Group Access)
Outside lines can be grouped together in up to four different groups. Users can program
an autodial button to select a line group or manually enter a dialing code for access to a
line. Grouping can reserve certain lines for certain clusters of stations as in a
tenant-service arrangement. The assignment of line groups frees station buttons normally
used for line selection thus making these buttons available for use with a feature such as
personal DSS/BLF with station-to-station messaging. Lines are placed in line groups
with the line class of service programming.
