Comdial Dxp Plus Instructions Manual

							Do Not Disturb (DND) Inhibit
The programmer can inhibit DND on a station class of service basis.
Do Not Disturb (DND) Override
The programmer can provide stations with a Do Not Disturb (DND) override capability that will allow
them to call a station that is set in the DND mode. The programmer must also enable the executive
override feature for the DND override feature to function.  Refer to the discussions titled: Do Not Disturb
and Executive Override.
DSS/BLF Console Support
The DXPPlussystem supports the use of both digital and analog proprietary DSS/BLF consoles.  The
installer can place a console at any station port and use database programming to identify it as a console
port. The installer then uses database programming to enable the console to be a companion to a
telephone that he or she has installed at any other station port. The system supports the use of up to four
consoles for each telephone, and there is no limit to the maximum number of consoles that it will support.
The DSS/BLF console provides a one-button direct station selection (DSS) intercom, an associated busy
lamp field (BLF), and additional autodial capability to the telephone user.
DSS Status Button
When the programmer assigns the personal intercom number of one telephone to appear at a button on
another telephone, the button and its associated light provide a direct station select (DSS) busy lamp field
(BLF) feature.  With this feature, the user can monitor the status of the appearing station. If the
programmer also assigns a DSS status button to the telephone, the user can press it to select between
monitoring all of the telephone status or just its personal intercom status.
Also refer to the discussion titledIntercom Number.

							Digital Voice Announce
The DVA is a line-powered device that provides voice prompts for auto-attendant and transfer, or you can
use it to enhance the operation of DISA and Tracker.  However, you must have DISA assigned for DVA
to function. The DVA is designed to interface with a digital station port and is easy to install and
program. You perform all DVA programming through the “Attendant Level” programming, though there
are some DXPPlusprogramming steps as well.  It isn’t necessary to send DTMF or ringing signals to the
unit to activate it because the DISA programming determines the DVA’s actions. When you use DVA in
conjunction with DISA, the DXPPlusautomatically answers CO lines and guides callers with voice
prompts.
Connect the DVA to any vacant digital station port. The DVA self-identifies to the CPU in the DXPPlus,
so you don’t have any phone-type programming to do.
The DVA accepts and stores up to four recorded messages, with a total maximum recorded time for all
messages of two minutes. The system attendant or installer can divide this two-minute period as
necessary among the four messages or use the entire two minutes for one message. These pre-recorded
messages play during an in-process call. Single digit dialing is allowed during each of the four prompts.
The system attendant or installer can store the customized messages (prompts) into the DVA device by
delivering them from the attendant’s station. The DVA interfaces with the DXPPlusthrough any of its
unused digital telephone station ports. The maximum number of DVA units you can install is limited only
by the number of DXPPlusstation ports (480). If you install multiple DVAs, the DVA functions as an
automatic attendant, and it enhances the operation of direct inward system access (DISA) by providing
automated voice prompts and dialing instructions to callers. In general, the voice prompts are of the
categories listed in the examples following this description.
You control the day versus night messages by programming the day 1, day 2, and night ringing begin and
end times in the system parameters menu. The system goes into the night mode either manually by the
attendant or automatically each day when the programmed times occur. When the system is in the night
mode, the night menu message plays versus the day menu message; likewise, the night routing message
plays versus the day routing message.
Message types, such as welcome greetings and recall-no-answer messages are indexed within the system
by a two-digit number (example: 10 = Welcome Greeting 1, 11 = Welcome Greeting 2, and so forth).
A single-digit number appended to many of the message-type names (example: Welcome Greeting 1,
Welcome Greeting 2, and so forth) is used for grouping similar types of messages together to prompt
callers. For example, a company sharing the telephone system with several departments may assign all
messages in group 1 to the sales department and all messages in group 3 to the customer service
department. This allows DISA lines coupled with voice prompt 1 to seek welcome group 1, and DISA
lines coupled with voice prompt 2 to seek welcome greeting 2, for departmental applications.
When programming DVA voice menus (example, press 1 for sales, 2 for customer service ...), you can
also enter feature codes as well as intercom numbers in the Voice Digit Translation menu. For example, if
you have installed the Tracker Paging System option, you can program the Tracker Pager access code
(*8) into one of the single-digit translation locations. This allows callers to track the called party by
pressing the appropriate single-digit button on their telephone when prompted by voice message. The
caller then enters his or her call-back number and the # symbol to complete the page.
NOTE: DVA prompts are shared; for example, if you make eight different recordings, with two DVAs, they will be
distributed in both units. If one DVA fails or is removed, then only the remaining messages will play.

							DVA Continued . . .
Lines are associated with DVAs by “Line Pgm,” DVA voice option. For example, in the diagram below,
lines 1, 2, and 3 are programmed for “voice option 1 and will be answered by any DVA unit with index
group 1 prompts recorded. Lines 4, 5, and 6 are programmed with voice option 2 and will be answered by
the DVA with index group 2 recorded.
The following are examples of DVA voice messages.
Welcome greeting
This greeting identifies your company or business.Example: “Welcome to Acme Company, one of our
agents will be with you as soon as possible.”
Day message
This message represents the main menu prompt used during normal daytime hours.
Example 1: “If you know your party’s extension, dial it now; otherwise, stay on the line—an operator will
be with you shortly.”
Example 2: “To reach engineering, dial 1; to reach customer service, dial 2; to reach sales, dial 3;
otherwise, stay on the line—an operator will be with you shortly.”
Night message
The night message is used after normal business hours have ended. Example: “Our office hours are from
eight to five. Please call back tomorrow.”
Recall no answer messages
Whenever a station is dialed from a DISA line and is not answering, the system plays a recall no answer
message to the caller. Example 1: “The party you have reached is unavailable at this time.” Example 2:
“The party you have reached is unavailable at this time. Dial 1 followed by your call-back number and
pound symbol to track the called party or dial 2 to leave a voice message.”
NOTE:In example 2, the installer must install the Tracker Paging System and proprietary voice mail
options.
Recall busy message
Whenever a station is dialed from a DISA line and is busy, the system plays a recall busy message to the
caller.Example: “The party you have reached is unavailable at this time—please dial another extension
or dial zero for the operator.”

							Hold message
This prompt is used during DISA calls and is activated when the called party is being paged with the
Tracker Paging system. Example:“The party you have reached is being paged—please hold.”
DISA authorization code message
This message prompts callers to dial their DISA authorization code. Example:“Please enter your
authorization code at this time.”
Feature access message
Before a caller using a DISA line can access system features, he or she must dial the proper feature code.
Example: “The following features are available. Dialk01 for system speed dial access,k8 for Tracker
Pager, or hold and you will be assisted by an operator.
Drop message
This prompt is used when a DISA call cannot be completed (not enough system resources available,
wrong access code dialed, or feature dialed is busy).
NOTE: The call is not routed to the attendant–the message plays, then reorders.
Example: “Your call cannot be completed at this time. Please try again.”
DVA / DISA
You can enhance the security of DISA by using the DVA. The DXPPlusseizes the incoming call based
on the “DISA assignment” parameters, and the DVA plays the appropriate prompts to enhance the

							Dynamic Save Button
Unprogrammed buttons at multiline telephones are available for the user to dynamically save dialed
numbers. To save a number, the user presses any unprogrammed button before hanging up after he or she
has dialed a number. To dial the saved number, the user presses the same button and the system
automatically dials the saved number. Saving a number over a previously saved number erases the old
one and stores the new one in place of it.
E
E1 Digital Carrier Transmission Option(International Applications)
The E1 digital carrier transmission option is designed for international applications and allows up to 30
channels of voice and/or data transmissions over a single four-wire cable using multiplexing techniques.
For convenience, a customer service unit (CSU) is built into the E1 option board to terminate the E1
channels, provide protection from transient voltages, and respond to loop-back requests from the central
office.
Up to four E1 boards can be installed if the expansion cabinet has been added to the main cabinet – two
boards in each cabinet. The DXOPT-SYN card on the Services board must be installed whenever one or
more E1 boards is installed, and the DXPPlusis receiving its timing signals from an external source. In
installations where the local DXPPlusis supplying the clock signal for the far system, no DXOPT-SYN
card is required in the local DXPPlus.
You can assign a system status button to a station and enable the system to report E1 transmission errors
via the T1/E1 status log. Depending on how you program the system, the E1 status log either prints out on
an optional printer or is displayed on an optional video display terminal (VDT). You can also view the E1
status log from an LCD speakerphone by programming a system status button.
Also, you can program the system to alert the system attendant whenever a major alarm alerting condition
occurs by activating an external, customer-supplied audible or visual alarm. The external alarm connects
to one of the relay jacks (J3 or J4) on the front of the CPU board. Make sure the alarming device complies
with system voltage and power requirements. You determine when a major alarm alerting condition
should occur by programming threshold values and corresponding time periods for each type of alarm
caused by a transmission error. Whenever the threshold value is reached within the programmed time
period, the selected relay on the CPU board is activated by the board’s circuits, which in turn, activates
the external alarm. The system attendant can turn the alarm off from any specified station by dialing a
feature code.
Pad Level—Transmit, Receive
(Gain And Attenuation Settings For Line Transmit And Receive)
This feature enhances the T1–E1 digital carrier transmission option, the pad level programming feature
adjusts voice levels for both the transmit and receive circuits in the individual channels.
The choices include: Gain 2, Gain 1, Nominal, Loss 1, Loss 2, Loss 3, Loss 4, and Loss 5. These settings
provide an approximate +6 to -15 dB range of choices. Starting at the Nominal setting, each gain level
represents an approximate 3 dB amplification of the signal level from the previous setting, and each loss
level represents an approximate 3 dB attenuation of the signal level from the previous setting. Because
digital transmission does not lose volume level as readily as analog transmission does, it is likely that the
receive level may be noticeably higher when using the E1 option. Therefore, you may need to select a low
setting such as Loss 2 for the voice level receive parameter when programming this feature for E1 lines
that are being used exclusively for voice transmission. Further, if you choose a setting to increase the
receive gain, you should carefully examine speakerphone operation. It is possible to select a receive gain
that will, under certain conditions, interfere with proper speakerphone operation.

							E & M Tie Line Support
Extension Hunting
When an E and M tie line call rings at a station that the programmer has disabled though programming
action, the system routes the call through the disabled station’s hunt list until it locates a group intercom
for the call to ring. Should all group intercoms be busy or should no one answer the call in a programmed
number of rings, the system then routes the call along the station’s call forwarding arrangement. With a
hunt list containing up to eight assigned group intercoms and access to each group intercom available to
several system stations, many users have an opportunity to service an E and M tie line caller. Coupling
this flexibility with the station’s call forwarding ability, provides many chances for system users to
service E and M tie line calls. A programmer could program a hunt list and a call forwarding scheme to
an unassigned station and provide a designated E and M tie line termination and routing center. There
would be no need to connect a telephone to the station port to use the feature in this manner. The
programmer could arrange several E and M tie line termination centers to service different extension
numbers. Each extension number could represent different calling categories, and ring at different blocks
of system stations (Also seeMultipurpose Line Board Support).
End-to-End DTMF Signaling
The system accepts DTMF tones or digital signals from proprietary telephones and sends them as DTMF
tones through the public telephone network where they are received at a distant end for computer, voice
mail, or other peripheral feature access.
End-to-End Signaling On Intercom
After establishing an intercom call, the system can continue to send and receive dialing signals (DTMF
tones) through the intercom path. This feature can be performed from every station in the system and is
used by peripherals such as a VMI–X or ATI–D–1PT accessory unit for voice mail.
End-to-End Signaling On Lines
After a user has established an outside call, the system can continue to send dialing signals (DTMF tones)
through the public switched network and have them received at the distant end for inward call completion
(bank by telephone, voice mail). Users can perform this conventional, on or off-hook dialing feature from
every station in the system.

							ExecuMail Integration
The DXPPlussupports the ExecuMail voice mail system through an appropriate interface device. The
ExecuMail system provides voice mail boxes where callers can leave messages to station users when the
users are not available to answer their telephones. The ExecuMail system camps incoming calls that
encounter busy ports so that they can recall when a voice mail part becomes available.
Also refer to the paragraph titledVoice Mail Integration Digits.
Executive Override
This feature allows the user of a station, upon encountering a busy signal at another station, to dial a
special code that will override the busy condition, sound a warning tone, and allow caller access to the
existing conversation.
Conditions for executive override are as follows:
·Calling station has class of service that enables busy override.
·Calling station is switched to override voice path.
·Called party may respond and will be heard by calling station and outside party.
·When the calling party dials the override code, the called party receives several tone bursts.
Also refer to the feature discussion titledDo Not Disturb.
Executive Override Advisory Tone
Beginning with software 4A, the executive advisory tone allows programmers to configure the system to
provide an audible tone whenever a system user activates the executive override feature. Programmers
can select this tone as either a one time tone or as a periodic reoccurring tone. If they choose a reoccurring
tone, they must select the time interval between the reoccurring tones.
Executive Override Block
As a class of service feature, the programmer can block executive override at a station. When a station is
blocked, a caller cannot override a busy condition and break into an on-going conversation at the called
station.
Extended DTMF Tones
The installer can program the length of the DTMF tones associated with automatically or manually dialed
numbers on analog telephones. This feature allows the system to access equipment such as answering
machines, banking computers, voice mail equipment,  that requires DTMF tones longer than the defaulted
80 msec. tone. To use the feature, the user programs the digits that require longer DTMF tones into speed
dial locations or waits until the DTMF dialing time threshold exceeds the limit.
Extended DTMF Tones For ExecuMail
The programmer can set different DTMF tones for ExecuMail Stations. The system defaults the length to
80 msec., but the programmer can set other tone lengths as needed.

							External Paging Interface(External Paging Port)
The external paging port, available on the services circuit board, provides an interface for external paging
equipment. When the programmer assigns the external paging port to a paging zone, announcements to
that zone are sent through the external paging equipment installed at the port. When the programmer
assigns one of the relays that are available on the central processor unit circuit board to the paging zone, it
provides a dry-contact actuation for the duration of the page to that zone. Typically, the installer wires
the system so that this actuation enables the external paging equipment while the paging signal is sent
through it.
The programmer can program a line port as an external paging interface for an external paging amplifier.
When this feature is available, station users access the amplifier by selecting that line port. The paging
line port accepts dialed DTMF tones to make a zone selection if the amplifier provides this function.
When the programmer assigns a flexible ringing assignment to the external paging port, the external
paging equipment responds to a ring signal and sounds the ringing over the paging loudspeaker. The
programmer can assign one of the common audible ringer interface relays to track the ring signal that is
supplied to this external paging port. Typically, the installer wires this relay so that its contact actuation
enables the paging equipment.
Also refer to the discussions titledAuxiliary Ringer Interface, Common Audible Ringer Interface, Flexible
Ringing Assignments, Line Answer From Any Station,andNight Transfer (Of Ringing)
F
Feature Inhibit
The programmer can disable a large array of individual features to provide a very basic telephone system
when it is necessary. A basic system might be necessary at a site where a large proportion of the
telephones are accessible to unauthorized users that may use them to tamper with the system, or such a
system may be necessary for locations where users only need a narrow range of features to do their job.
Feature Renumbering
While the dialing codes for personal and group intercoms and for feature access are set by system default,
they are flexible, and the programmer can renumber them when necessary. Feature renumbering may be
necessary if personal or group intercom numbers must be in a certain block or sequence to match some
site requirement (for example, numbering all telephones located on the third floor with 3nnn numbers). If
a new number assignment conflicts with a defaulted dialing code, the defaulted code can be reassigned
into a block of unassigned numbers set aside for that purpose.
At default, the blocks of numbers are as follows:
1001 – 1480 = personal intercom
4001 – 4480 = group intercom
5000 – 5039
6000 – 8999 = feature codes
5040 - 5999 = unassigned codes
9 = line group 1
The programmer can reassign any number between 1 and 9999 to any intercom or feature code in any
combination of three- or four-digits; however, the assigned numbers must not conflict with one another.
For instance, if 2111 is assigned as an intercom number, there cannot be any intercom or feature code
numbered 21, 21n, or 21nn. Similarly, since 9 is defaulted as the code for line group one, there cannot be
any intercom or feature code numbered 9n, 9nn, or 9nnn.
