Comdial Dsu II Digital Telephone System Instructions Manual

							Subdued Off-Hook Voice Announce (SOHVA) Groups
The programmer can program the ability of station ports to originate and/or receive
SOHVA calls by assigning SOHVA calling groups to station ports. This means that he
or she can arrange certain station ports together for SOHVA calling between one another
while excluding other station ports in the system from this group.
The system provides eight different SOHVA groups that are fixed into a variety of
SOHVA receive/originate configurations. A programmer can assign one SOHVA group
to each station port to allow or to deny SOHVA receive and/or originate capability to it.
By properly assigning SOHVA groups to station ports, the programmer can open or
block SOHVA paths between stations.
The system is defaulted with no SOHVA groups assigned. When a station port does not
have a SOHVA group assigned to it, it’s user can originate SOHVA calls to any station
port and receive SOHVA calls from any station port.
SOHVA groups arefixedby the system into the following configurations:

							Example 1: Allow station port 10 to originate SOHVA messages to all stations in the
system and allow those stations the ability to originate SOHVA messages to each other
but not to station port 10. Assign group 1 to station port 10 and assign group 2 to all
other station ports.
Example 2: Allow station ports 14 and 15 to receive and originate SOHVA calls
between each other but deny both receive and originate capability from any other system
stations. Assign group 8 to both station port 14 and station port 15. Do not assign group 8
to any other station portbut be sure that all station ports have a group assigned to them.
The programmer assigns SOHVA groups using the station class of service programming
procedure.
Subdued Ringing
When a station is busy on a call and another call comes to the same station, the system
will automatically subdue the ringing of the second call to a lower volume.
See also,Ringing.
System Alarm Reports
The programmer can arrange the system to report alarm and status conditions to a
particular station or stations that he or she has enabled to receive them. The alarm
receiving station must be an LCD speakerphone. When a station is enabled to receive
alarms, its user can take appropriate action to cause the alarm codes to be presented on
the LCD display. A programmer must use both system and station class of service
programming to enable this feature.
System Speed Dial
The system provides 99 system-wide speed dial numbers. The system speed dial numbers
can be up to thirty-two digits in length, and can include numbers, #,S, pauses, and
hookflash signals. The attendant programs the system speed dial numbers and names at
station 10 or 12 for use at every station in the system. No class of service programming is
required.

							T
Tandem Attendant
When the programmer uses system class of service programming to enable the tandem
attendant feature, a recall from an unanswered call transfer or a timed hold recall will
ring at the normal attendant station (station 10) that set the transfer or hold condition, and
also ring at the tandem attendant station (station 12).
TAP (Flash/Recall)
If the host system provides custom calling features via a hookflash signal, the
programmer should program the system so that the TAP button will generate a “flash”
signal when a user presses it. If custom calling features are not available to digital
telephone system users, the programmer should program the TAP button to function as a
positive disconnect, dial tone recall button. The flash and recall features are mutually
exclusive. The programmer uses the system class of service programming procedures to
set the flash or recall TAP time.
Tenant Service
A system programmer can arrange for one telephone system to be used for multiple
tenants at a site location by employing flexible line appearance at each station. The
programmer can perform button mapping for line appearance on each station in the
system using the station class of service programming.
See also,Square/Non-Square Configuration.
Timed Hold Recall
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. The programmer sets the timed hold recall time
period using system class of service programming.
See also,Hold.

Digital Telephone System Features A – 67 
						

							Toll Restriction
Default Toll Restriction
The system defaults two toll restriction tables with pre-programmed values and
pre-assigned to all lines. The programmer needs only to assign these tables to the stations
by programming action to put them into effect. He or she can use the toll restriction table
configuration class of service programming to reprogram the defaulted tables with
different information as needed.
Flexible Toll Restriction
A system programmer can configure system toll call 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. The programmer
needs only to enable the default 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 can contain up to four entries and each
entry can contain up to 16 digits.
A programmer programs 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. This
arrangement allows the programmer to enable exceptions to toll restriction. For example,
he or she can arrange the table entries so that the system allows the dialing of
1-800-xxx-xxxx numbers even though it denies the dialing of all 1-xxx-xxx-xxxx
numbers. A programmer can store a “match anything” symbol (#) to represent any digit
from 0 to 9 in the individual entries thus providing him or her with a broad range of
number combinations to choose from.
The programmer can individually assign the programmed toll restriction tables to each
appropriate station and line. Therefore, when an outside call is dialed, the system
examines the dialed number and makes a comparison between it and the toll restriction
tables. Any tables that the programmer assigned to BOTH the station being used and the
selected line determine the restrictions to be imposed. It should be noted that the system
will automatically disconnect a line from a station if its user dials a restricted number on
a restricted line from a restricted station.
Night Mode Toll Restriction
A programmer can assign toll restriction tables to any or all stations in the system that
will only take effect when the system is in the night transfer (of ringing) mode. These toll
IMI66–132 DSU II Digital Telephone System
A – 68  Digital Telephone System Features 
						

							tables replace any that he or she may have assigned to the station for normal, or day
mode, operation. For example: a programmer can arrange for a station that has no other
toll restriction table assignment to receive a toll restriction table which 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 users can make toll calls from this
station during daytime operation, they can make no toll calls from it when the attendant
programs the system for nighttime operation using the night transfer of ringing feature.
NOTE:Do not confuse this night mode toll restriction table assignment with the night
transfer (of ringing) feature.
Toll Restriction Override
The toll restriction override (TRO) feature allows users to override the toll restriction that
they encounter at other stations with their own station’s toll restriction assignments. In
programming for this feature, the programmer creates a four-digit TRO code that users
can dial to override the toll restrictions of any station that they happen to be using and
replace it with a toll restriction that matches their home station. After entering a TRO
code, a user gets his or her own prime line or idle line preference and its accompanying
toll restriction assignment. They then have 15 seconds to dial an outgoing call. Once they
hang up from a call, they have 15 seconds to make another call without having to re-enter
their TRO code. The system marks outgoing line calls that users make after entering a
TRO code with a (T) in its SMDR/SMDA printouts. The station number that it prints is
that of the overriding station and not the actual station that the call was made from. If a
user transfers a TRO call or places it on hold and picks it up at another station, the call
belongs to the new station.
Positive Disconnect Supervision
When a station is on line with an outside caller and the caller hangs up, the CO may send
a positive disconnect signal to the telephone system. A programmer can enable a positive
disconnect supervision feature on a per line basis. With this feature enabled when the
telephone system detects the CO’s positive disconnect signal, the system resets the toll
restriction, releases the current call record, and creates a new call record in its place.
Tone Or Voice Signaling (Intercom)
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.

							Tracker Paging System
The optional Tracker Paging System is a wireless paging system that uses an external
base station connected to the common equipment cabinet and individual portable pagers
assigned to the system station extension numbering plan. The Tracker Paging System
allows telephone users to send alpha/numeric or numeric-only messages to Tracker
pagers assigned to station extension numbers. The type of message that the system
delivers is dependent on the model Tracker pager being used. The Tracker base station
requires only one connection to the digital telephone system; however, the installer will
need to take several programming steps to make it operational.
Transferring Calls
SeeCall Transfer.
Transfer/Conference Button
The telephones provide this fixed button that gives quick, easy transferring and
conferencing.
U
Unanswered Call Transfer Recall Timing
A transferred call that is 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 the tandem attendant feature is enabled. When LCD speakerphones are employed,
the display will show the station number or name as well as the line number that is being
re-called. The system class of service programming determines the recall time for an
unanswered call transfer.
See also,Call Transfer.

							Unscreened Call Transfer
A user can transfer a call to another station without first announcing it. The transferred
call will camp-on to the other station where it will ring and await an answer. The call will
automatically ring back to the transferring station after a programmable recall period.
There is no limit as to how many calls users can camp-on to another station. A
transferred call will only ring if the station is idle. If the station is busy, the call will wait
until it is idle before it rings. The programmer can use the system class of service
programming to set the recall time for an unanswered transferred call.
See also,Call Transfer.
V
Visual Voice Mail Support
Visual Voice Mail (VVM) support provides proprietary, two-line display LCD
speakerphone stations with visual messages and interactive buttons. This message and
button fuctionality enhances the stations with visual messages and interactive buttons.
This message and button functionality enhances the station’s use with Comdial Versatile
Voice Processing (VVP) voice mail equipment. To implement VVM support, the system
programmer must enable it with class of service programming action. Since VVM
requires the same serial data connection to the common equipment cabinet as does the
Tracker Paging System, the Tracker Paging System is unavailable while VVM is
operational.
When enabled, VVM causes the speakerphone to display aVMAILbutton that users
press to call the voice mail system. After they press this button, the system prompts them
to enter a password. (This password is one that the programmer assigns to the stations.)
Once users enter the password, the speakerphone’s display shows the VVP’s main menu.
From there, users can select the operation they wish to persue.
When there is a message waiting, the display shows the message quantity in place of the
VMAILbutton (for example,5 MSG). Users press theMSGbuttonw to play the stored
messages. The system prompts the user to enter a password (if programmed to require
one) before it plays the new messages.

							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.
SeeIntercom.
Voice Mail Support
The digital telephone system supports the use of voice processing equipment connected
to the system’s station ports through the ATI-D analog terminal interface. The ATI-D is
a multipurposeon-premiseaccessory for the digital telephone system. It has dual circuits
that allow the voice mail equipment to interface to two station ports. In addition to the
required programming task of identifying the station ports as voice mail ports, there are
several other programming considerations associated with voice mail operation that the
programmer can make whenever their options are wanted. These options include the
following features:
Automatic Attendant
With the automatic attendant feature, the voice mail system automatically answers any
line that is ringing at a voice mail port.  As a default, the system automatically enables
ringing line preference for any port the programmer identifies as voice mail ports. The
programmer must choose a ringing assignment for the lines assigned to the voice mail
port before the voice mail system can provide the automatic attendant feature.
Automatic Transfer Of Voice Mail
The programmer can choose the immediate transfer mode for voice mail transfers.
However, if he turns on the screen and/or confirm options provided by the voice mail
system, he must not choose the immediate transfer mode because it allows the system to
transfer a call as soon as it answers it precluding any screen and confirm action that the
voice mail equipment can provide.
Hunt Groups
When a station port that has been assigned to an intercom hunt group is busy, a call to it
will ring at the next idle station port in the group. A call will try to ring every port in a
hunt group and if all are busy, the telephone system will return a busy tone to the caller.
A programmer can assign all voice mail ports to a circular hunt group to take advantage
of its multiple-port interface capability. With this arrangement, a call will first try to ring
at the first port, then try the next one and so forth until it tries all four ports.
IMI66–132 DSU II Digital Telephone System
A – 72  Digital Telephone System Features 
						

							Positive Disconnect Supervision
When a station is on line with an outside caller and the caller hangs up, the CO may send
a positive disconnect signal to the digital telephone system. The system passes this signal
to the voice mail equipment thus signaling it also to hang up.
Voice Mail Line ID
The programmer can program the voice mail lines with identification (ID) numbers that
allow the voice mail equipment to identify which line it is answering. The ID numbers
that the programmer assigns here must match the ID numbers that are selected as part of
voice mail system programming.
Voice Mail Pause
Some voice mail systems allow you to program a pause before they dial an extension
number. You can program the digital telephone system to pause before receiving digits
from a voice mail system. This capability allows the digital telephone system to match
the voice mail system’s pause. If the voice mail system does not pause before dialing an
extension number, you must disable the fixed one second pause in the digital telephone
system.
Voice Mail Transfer On Busy
The programmer can arrange the telephone system to alert a busy telephone that the
voice mail equipment is attempting to transfer a call to it. Without this programming, the
voice mail equipment will automatically route the call to a voice mail box when it
encounters a busy signal. With this option, when the voice mail equipment tries to
transfer a call to a station that is busy on a call (outside or intercom call) and the station
has an available intercom line (stations can be programmed to have a second intercom),
the intercom will ring subdued. The user can answer the call by pressing the button of the
ringing intercom line. In general, attendants will probably desire this feature so they can
handle multiple calls, while other station users may prefer to have a message taken when
they are already busy on a call.
Volume Control
EveryImpact, Impression, DigiTech, and Scout telephone has a multipurpose volume
control for adjusting the loudness of the ringer, the speaker, the handset, the headset, and
the group listening mode. LCD speakerphones display the new volume setting whenever
the user presses the rocker switch volume control located on the telephone’s faceplate.
There are four ringer levels (Scout has two plus off). At default system settings, users can
set the ringer loudness at their stations from completely off to maximum. System
DSU II Digital Telephone System IMI66–132
Digital Telephone System Features A – 73 
						

							programmers may disable the ringer-off feature on a system-wide basis. When
programmers take this option, users can set the ringer volume to a low level but cannot
completely silence it.
The number of handset loudness levels is different for the different telephone models.
The DigiTech telephones have 8 handset volume settings. At default,Impactand
Impression telephones have 8 handset volume settings, but the installer may increase the
number of volume settings on individual stations to 13. Users working in noisy
environments and users with hearing impairments may find the increased number of
volume settings useful. The Scout has two handset volume levels.
There are 8 headset volume levels on DigiTech telephones, 13 onImpactand Impression
telephones and two on Scout telephones.Impact,Impression, and DigiTech telephones
have 8 speaker volume levels. DigiTech telephones have 7 group listening volume levels,
Impactand Impression telephones have 8.
Z
Zone Paging (Via Station Speakers)
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.
