Comdial Unisyn System Manual

							IMI66-112Description Of System FeaturesM
Manual Hold
A button activated feature at each station will place an outside line on hold. Pressing the HOLD button holds the
call, provides a distinctive flash rate of the line button indicator, and allows the user to access other station features.
‘Ihe holding station or any other station that has access to the line can retrieve the held call. No class of service
programming is required.
Memory Retention Without Batteries
An electronic device sometimes referred to as a “super-cap,” electronically protects the system memory during AC
power failures.
The stored program data will remain in memory for a minimum of 70 hours, provided that the
system has been powered continuously for at least 30 minutes prior to the power failure or disconnection.Some
models include a system clock. On those models, the system clock will continue to run and keep time for at least 24
hours after an AC power failure or disconnection.No 
class of service programming is required.Message Waiting-3 
7.28-
Special feature access codes enable a station user to control the message waiting (MW) light at other stations in the
system.W’hen a user turns on the message waiting at a station, a call can be 
automaticaIly placed to the station that
turned it on. The message-waiting light automatically turns off when the called party answers.
If a station has a 
DSS/BLF appearance at another station, the station user can leave a call-back message indication at
that other station. By dialing a special code, the user can activate the BLF light at the called station. This light
indicates that the user’s station has requested a callback. The system automatically turns off the light if a successful
callback is made.
Mixed Station CapacitiesSee-Port Definition.
Modular Wiring And 
Jacks/4-conductor Wire System
You can completely interconnect the system by employing industry standard 5@pin. coMe&ors and modular
plug/jack combinations. Station wiring is 
4-conductor,twisted-pair cable (2-conductor twisted pair cable for IST)
throughout the system. No class of service programming is required.Music Interface (External Source 
Required)-2.7.6-

Night Ringing-3.7.18-
Night transfer 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. Select the individual lines at each station 
that are to have ringing transferred with
this feature with station class of service programming.0
On-Hook Dialingx‘2
Every multiline station provides manual and/or automatic dialing while the station handset is on-hook. An internal
speaker monitors call progress for completion.(The handset must be taken off-hook to provide the voice link on
non-speakerphone stations.) No class of service programming is required.Originating Denied-3.7.1 
l-
You can deny individual stations the ability to originate calls on certain lines through system programming.
Program the originating denied feature 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.P
Pause 
Time-3.5.12-
During speed dials, it is sometimes necessary to delay the sending of digits to give switching equipment time to
prepare for receiving those digits. The system stores a pause for this purpose whenever the user presses the HOLD
button.You can program the length of the pause through class of service programming.
PBXICENTmXKO Compatible
System features and programmable buttons support the requirements of most PBXs, Central Offices, and CENTREX
systems. Numbers, 
#‘s, Ws, programmable pauses, and flash signals can be made a part of every stored number for
access to host system feature codes. No class of service programming is required. The system supports IST
hookflash for 
CENTRBX features via access code.Personalized Ringing 
Tone-3.7.25-
This feature allows a station user to choose one of four different ring tones to aid in distinguishing one ringing
station from another.Pooled Line Access 
-3.6.5-
Users can dial a special access code instead of pushing a line button to access one of four different groups of lines.
Single-line telephones do not have line appearances, so a user must use this feature for accessing an outside line for
dialing out. Lines are arranged into groups with the line class of service programming.
Port Definition-3.7.26-
You can program a station port to accept one of several different types of equipment, such as an LCD speakerphone
or a multiline line telephone.Power Failure 
Transfer-2.7.1-
A power failure line connection is available for connecting industry-standard telephones such as a Comdial model
2500. These power-fail telephones automatically connect directly to certain lines whenever there is an AC power
failure.Normal origination and reception of calls on a power-fail station is possible during the power failure
condition. The power-fail stations will automatically disconnect as soon as power is restored. No class of service
programming is required.5-12 
						

							IMI66-112Description Of System Features
Prime Line Automatic-3.7.27-
If you program a station for prime line automatic, the system automatically selects the designated outside line,
intercom line, or line group when the user takes the handset off hook.
Users may pre-empt prime line pickup by
selecting another line before lifting the handset. If the prime line is ringing, it is automatically answered when the
user lifts the handset.
Privacy Release-Designated Programmable Button-3.8.10-
You can program stations to provide a privacy button. If a line is private, a user can press the privacy button to
change it into a non-private one. If the line is non-private, pressing the button will have no effect.
Private Lines (Access Denied)See -Access Denied.
Programmable DSS/BLF (Direct Station Selection/Busy Light Field)
A multiline station user can store one-button, direct station selection (DSS) at any programmable button location to
create a DSS button. When a user presses this button, the system automatically places any active outside call on
hold and then makes an intercom call to that previously stored station number. The visual indicators of the stations
programmed at the button locations form a busy lamp field 
(BLF). The BLF conveys station status to the user.
You
can also program a speed-dial number as a secondary function at every 
DSS/BLF memory location.
No class of
service is required. Also see-Tone or Voice Signaling (Intercom).Programmable Buttons
See-Full Button Programmability of Features, Programmable DSS/BLF, and Dedicated Programmable buttons.Pulse/Tone 
Switchuble-3.6.9,3.6.10-
You can program the system on a per-line basis to allow the stations to switch from pulse to DmF dialing as
needed. Alternately, you can program the system to only allow tone dialing.
R
Remote Access And Administration
Remote upload and download of the system and SMDR output for printing are both available through serial data
ports. These data ports will 
support X-on X-off control codes for terminal control as well as a DIR signal for
handshaking.They also have the popular XMODEM protocol so that the system database can be uploaded or
downloaded, error free, from or to a remote computer running software that supports the XMODEM protocol.Use
serial port one for programming and serial port two for SMDR.
Ringing Line preference-3.7.29-
You can program the system on a per-station basis to provide ringing line preference on all lines programmed for
ringing at the station; ringing line preference activates the yellow lamp.
When you enable ringing line preference at a station, taking it off-hook aI.ItOm~C~~y conncxts it to my oUtsi& line
that is ringing.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 with line selection is
enabled by the station class of service programming.

							IMI64-112Description Of System FeaturesSystem Speed 
Dial-3.5.8-
The system provides up to ninety-nine system-wide speed dial numbers. The system speed dial numbers can be up
to 16 digits in length and can include numbers, 
#‘s, %‘s, pauses, and flash signals. Program system speed dial
numbers at station 10 or 12 for use at every station in the system. No class of service is required.T
Tap (Flash) /Recall
: :.-:.
When host system custom-calling features are available via a hookflash signal, you can program the system so that
the TAP (RECALL) button will generate a “flash” signal when a user presses it. When custom calling features are
not available, the TAP (RECALL) button functions as a positive disconnect, or dial tone, recall button. These two
features are mutually exclusive. IST support is feature code activated (future feature).
Tenant Service
You can have one telephone system function for multiple tenants by having flexible line appearance at each station.
You can use button mapping for line appearance on each station using the station class of service programming.
Refer to the discussion 
titled: SquareAVon-Square Configuration.
Timed Hold Recall-3.X14-
After a call has been on hold for a programmed length of time the system will re-call the station that placed the call
on hold.
Toll Restriction (0 And 1)
See the discussion titled: Toll Restriction (flexible).Toll Restriction (Flexible)-3.1 
O-
You can program toll restriction to prohibit some or all stations from calling a wide range of number combinations.
The restricted numbers are specified on up to 16 tables. The system assigns several broad-range values to two of
these tables and assigns the tables to all lines as a default condition.All you need to do is to default the tables on a
per-station basis to activate the default toll restriction.
In general, toll restriction works as follows:
The programmable tables of restricted numbers contain up to four entries with each entry containing up to 16 digits.
You can program each table of restricted numbers to be an “allow” table or a “deny” table with entries in an “allow”
table overriding entries in a “deny” table. For example, the dialing of 
l-800-xxx-xxxx numbers can be allowed even
though the dialing of all 
I-xxx-xxx-xxxx numbers is denied.
The system can store a “match anything” symbol 
(#) to represent any digit from 1 to 0. Assign the programmed toll
restriction tables to each appropriate station and line. When a user dials an outside call, the system examines the
dialed number and makes a comparison between it and the toll restriction tables.Any tables assigned to 
BOTH the
station being used and the selected line determine the restrictions to be imposed.
Dialing a restricted number on a restricted line from a restricted station will cause the line to be automatically
disconnected from the station.
Note: On bridged proprietary and IST stations, the system cannot always verify toll restriction from the IST
telephone.You should use caution when installing a bridged telephone in areas where abuse could occur.
5-1.5 
						

							Description Of System FeaturesIkfIG-112Toll Restriction (Night Mode)-3.10.6
You can assign toll restriction tables that will only take effect when the system is in the night transfer of ringing
mode. You can assign these night mode tables to any or all stations in the system .These toll tables work in
addition to any tables that may already be assigned to the station. For example: You can program a station-that has
no other toll restriction table assigned to receive a toll restriction table that will restrict everything but local calls and
will only take effect when the system is placed in the night transfer of ringing mode.Therefore, even though a user
can make toll calls from this station during daytime operation, he or she cannot make toll calls when the attendant
programs the system for nighttime operation using the night transfer of ringing feature.
Note: This night mode toll restriction table assignment should not be confused with the night transfer of ringing
feature.
fToll Restriction Override-3.10.6-
A station user can override a toll restriction at a particular station with his or her own toll restriction table.
.?
Tone Or Voice Signaling (Intercom)
You can program the system as either tone or voice first for the primary intercom
The user can activate the alternate
method at his or her station. The system marks intercom call progress by special tone signals. Also 
see-IntercomCall Progress Tones.
Transfer / Conference Button
The system provides a fixed “CONF” button that gives quick, easy transferring and conferencing. No class of
service programming is required.
Trunk Access RestrictionSee-Access Denied.
u
Unanswered Call Transfer Recall Timing-3.5X-
A transferred call that goes unanswered after a pre-programmed length of time will return to the station that
transferred it. The system will return the 
call to both attendant stations when you have enabled the tandem attendant
feature. When the station uses an LCD speakerphone, the display will show the station number as well as the 
line
that is being re-called.
V
Voice Announce Blocking-3.7.30-
This feature allows the user of multiline stations to block voice announced intercom signaling by dialing a special
code (or using a preprogrammed button).Z
Zone Paging (Via Station Speakers)-3.7.3-
Zone paging allows groups of stations to receive announcements through the station speakers. You can enable zone
paging in up to four different zones. Zone paging can be received at a station port that has been programmed as a
PA port and connected to an external loudspeaker.
AGO see-All-Call Paging (Via Station Speakers).
