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...

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...

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...

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...

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...

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...

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....

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...

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...

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...
