Comdial Dxp Plus Instructions Manual

							Pulse characteristics such as repetition rate, pulse width, pulse amplitude, and average ones density ((ratio
of one (1) bits to zero (0) bits)) are as specified by digital signal level 1 (DS-1) described in American
National Standards Institute Specification, ANSI T1.403-1989.
Detailing Where You Can Install T1/PRI Boards and Its Supporting Needs
Since the DXPPlussupports a maximum of 240 lines, and each T1/PRI board handles up to 24 channels,
you can install up to 10 boards in the DXPPlussystem. You can install these 10 boards in any available
universal board slot in the main or expansion cabinets. Of course, any other line boards that you install,
such as loop start, DID or multipurpose, reduce the number of lines available for T1/PRI service and thus
reduces the number of T1/PRI boards you can install.
Whenever you install one or more boards, and the DXPPlusis receiving its timing signals from an
external source (the usual case), you must install one synchronization card (DXOPT–SYN) on the
services board. This means when you connect the system to central office (CO) lines, you must include a
synchronization card, and the DXPPlusclock must be controlled by CO signaling.
CAUTION
For operation with the DXP Plus, the T1/PRI board must be Revision B or higher and have
special-purpose firmware installed.

							SMDA Metering Pulse Totals
DXPPlussoftware 11A enhances the SMDA Metering Pulse Totals by adding a third option to the
Report Option field. You can now select the option “Meter Pulses” as an alternative to “Call Cost” or
“Hold Time” on all reports.
Metering Pulse is a method used in countries other than the United States to determine call duration and
cost. Therefore, if you are installing the DXPPlussystem in a country that uses E1 lines, selecting this
option will allow the DXPPlusto cost calls by monitoring the metering pulses originating from the
central office.
SMDA Report On Answer
The SMDA Report On Answer feature enhancement for DXP 11A adds the option to create a report entry
only for answered outbound calls. When this feature is enabled, outbound calls initiated on lines which
provide answer supervision will not generate a report unless the call is answered. Call cost and time are
based on call duration after answer.

							ANI/DNIS Display
Software 11B adds the ANI/DNIS display feature. Automatic Number Identification (ANI) describes a
code delivered by the subscriber service along with an incoming call. ANI identifies the number that the
caller calls from. Dialed Number Identification Service (DNIS) also describes a code delivered by the
subscriber service; however, DNIS identifies the number that the caller dialed.  Systems can make use of
these two services in different ways. One use is to show the ANI or DNIS information on the display of
an LCD speakerphone. Through programming action, you can set the system for which bit of information
(ANI or DNIS) that you wish to have display priority or you can set the system to show both bits of
information in the display.

							PCIU/Visual Call Manager Support
Beginning with software release 11B you can use the Personal Computer Interface Unit (PCIU) to operate
the Visual Call Manager (VCM) capability of the Versatile Voice Processing (V.V.P.) voice mail system.
VCM provides a series of computer-displayed menus that V.V.P. users can use to simultaneously view
and manage voice message activity. By using a series of PC screen menus, users click their computer
mouse to send, forward, save, delete, and listen to voice mail messages with the system digital
speakerphone providing the sound. In addition, users select from different personal greetings, annotate
saved messages, see the length of messages, and perform many other functions from the PC screen.
Installers connect the PCIU between a digital station port and that port’s proprietary digital speakerphone
and also to a user-supplied PC. The PCIU includes Service Provider Interface (SPI) and desk-top VCM
software that installers load on the user-supplied PC. The SPI software, in conjunction with the VCM
software, allows the PCIU to use the serial data path between it and the user-supplied PC to send
messages to the PC and to the telephone’s display.
Making the PCIU/Visual Call Manager operational requires only that installers make the proper
connections as described in IMI89–286,Installing The Personal Computer Interface Unit,and load the
SPI and VCM software on the user-supplied PC.  There are no telephone system software programming
requirements to activate the PCIU; however, installers must consider the following hardware parameters:
·the user-supplied PC must be running the Windows 3.1* or Windows 95* operating system;
·the user-supplied PC must provide a serial data port (the PCIU includes a 9-pin to 9-pin cable serial
data cable);
·the system software revision must be at 11B or later;
·the V.V.P. software revision must be at 8.2 or higher;
·the system station must be a Comdial proprietary LCD speakerphone with interactive buttons;
·the revision of the firmware on the digital station board must be at 5A or later.

							Phone Types Enhancement
(Telephone Types)
This programming feature allows you to identify the particular type of system telephone equipment that
you or your installer will connect to each station port.
Beginning with software 11B, the digital communications system supports the installation of an
integrated voice processing board as a digital station type selection. The model number of the Comdial
integrated voice processing board is as follows: IVPC
You can also mark the station port equipment as undefined so that the system will not test the port for a
specific type of equipment and will not include the port in any menu presentations.
NOTES:(1) Depending upon which equipment you choose, the system will present different sub-menus that allow
you to further define the equipment as to the quantity of lines it can serve, whether it is a speakerphone,
whether it is a DSS/BLF console, and other defining characteristics. Follow the sub-menu prompts and
press ENTER after you have typed each selection.

							Restricted Login
Software release 11B, provides upward and backward compatibility between the different revisions of the
VMMI programming software and the software of the system being programmed. This compatibility is
for certain critical features and is known as restricted login. For example, restricted login permits
programmers to use 11A VMMI software to execute certain programming features on an 11B system or
use 11B VMMI software on 10A systems.  Restricted login permits the programming of the following
critical features across software revision platforms:
·archive any database;
·restore any database that has the same revision software as does the
system to which the VMMI is connected;
·up-grade system software;
·reset the system;
·change the system passwords.

GCA40-130General Description 
						

							System Software Upgrade Enhancement
Beginning with software release 11B, digital communications system installers no longer need to accept
an automatic save of an existing database during a system software upgrade. Installers can choose to
maintain the existing data base by first archiving the data base, then upgrade the software, and finally
restore the database after the upgrade is complete. Alternately, installers can choose to allow the system
to clear the existing database with the master clear operation.
(TAB004–PLS p11)
GCA40-130General Description 
						

							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 functionality enhances the stations
with visual messages and interactive buttons. This message and button functionality enhances the
station’s use with Comdial Versatile Voice Processing (V.V.P.) voice mail equipment.
The V.V.P. prompts the user to enter a password (if programmed to require one) before it plays the new
messages. Once entered, the V.V.P. system provides presents convenient dynamic VVM features that
enhance the voice message processing.A dedicated V.V.P. user guide (GCA70–347), provides
complete V.V.P. and VVM operating detailscauses 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 V.V.P.’s main menu. From there, users can select the
operation they wish to pursue. When there is a message waiting, the display shows the message quantity
in place of theVMAILbutton (for example,5 MSG). Users press theMSGbutton to play the stored
messages.
The system does not require any programming action to implement VVM support; however, there are
four additional now available DTMF integration digits that are used to signal call progress information to
the Comdial V.V.P. voice mail system. The system defaults these values during a master clear operation
and they will save across databases from one system to another. These defaulted values are applicable
exclusively for Comdial V.V.P. voice mail systems and are detailed below.
Logon Digit
The telephone system transmits the logon digit to the V.V.P. voice mail system along with the station
extension number whenever a station calls the V.V.P. voice mail system and finds that the voice mail
system has no messages for that station. The V.V.P. voice mail system requires a value of9.
Logon With Messages Digit
The telephone system transmits the logon with messages digit to the V.V.P. voice mail system along with
the station extension number whenever a station calls the V.V.P. voice mail system and finds that the
voice mail system does have messages for that station. The V.V.P. voice mail system requires a value of8.
Ringing Digit
The telephone system transmits the ringing digit to the V.V.P. voice mail system when the voice mail
system is calling a station and that station is ringing. The V.V.P. voice mail system requires a value of4.
Invalid Extension Digit
The telephone system transmits the invalid extension digit to the V.V.P. voice mail system when the
voice mail system has dialed an invalid extension while attempting to call a station. The V.V.P. voice
mail system requires a value of5.

							Upgrading The DXP Plus Software
The DXPPlusdigital communications system includes system software when it ships from the factory.
At initial system installation, you do not need to load the system software to make the system operational.
Should you need to later reload the system software (for software up-grade purposes for example), you
can do so using the supplied system software disk. Use Windows File Manager or MS–DOS commands
to save the disk’s information from your computer’s floppy drive to its hard drive. Having the software on
your computer’s hard drive allows the data to load into the system’s memory much quicker than it would
from the computer’s floppy disk drive.
To load the system software information, your PC must be connected to the communications system.
CAUTION
The system does not automatically save the existing database during a software upgrade. If
you need to preserve the existing database, you must archive it before you upgrade the
software. After you upgrade the software, you can restore the existing database to the system.
1. Archive the existing the database.
(a)
From theSwitchpull-down menu, select theConnect To...menu item, connect VMMI to the
system, and return to theSwitchpull-down menu.
(b)
From theSwitchpull-down menu, select theArchive Databasemenu item.
(c)
Choose a memory storage location for the archive operation to use andOKyour choice. Since the
data base can be quite large, you should chose a location on your computer’s hard drive to ensure
that you have enough memory to store the data base.
(d) The system automatically archives its data base.
2.
From theSwitchpull-down menu, select theConnect To... menu item, connect VMMI to the
system, and return to theSwitchpull-down menu.
3.
From theSwitchpull-down menu, select theSystem Software Upgrademenu item.
4. The system automatically takes itself out of service.
5. Choose the location where the new software data resides (select disk drive, directory, and file), and
OK your choice. The system loads the software data, resets itself, and places itself back in service.
6. Restore the exiting database (if desired).
(a)
From theSwitchpull-down menu, select theConnect To...menu item, connect VMMI to the
system, and return to theSwitchpull-down menu.
(b)
From theSwitchpull-down menu, select theRestore Databasemenu item.
(c)
Choose the memory storage location that contains an archived data base andOKyour choice. The
system automatically restores its data base.
