Comdial Impact Dsu Instructions Manual

							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.

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.
IMI66–107Digital Telephone System
Digital Telephone System Features A – 71 
						

							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.
Digital Telephone SystemIMI66–107
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
EveryImpactand DigiTech 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. At default system settings, users can set the ringer loudness
at their stations from completely off to maximum. System programmers may disable the
IMI66–107Digital Telephone System
Digital Telephone System Features A – 73 
						

							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,Impacttelephones
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.
There are 8 headset volume levels on DigiTech telephones and 13 onImpacttelephones.
Impactand DigiTech telephones have 8 speaker volume levels. DigiTech telephones
have 7 group listening volume levels,Impacttelephones 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.
