Comdial Dxp Plus Digital Communications System Instructions Manual

							1.4ReLoading Or Up-Grading The System Software
The DXP Plus 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 DXP 
Plus 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 DXP Plus (see 
Section 1.1).
1.Turn on your PC and load the Windows software.
2.Select the VMMI program from the Windows menu screen.7

1.5Using VMMI Software To Translate A DXP DatabaseYou can use the VMMI software to translate the database residing in a DXP to a format that is
compatible with the DXP Plus, and load that database into the DXP Plus system. While translating data,
your PC need not be connected to the DXP 
Plus.Before you translate a DXP database, determine the revision level of the DXP system software. If the
DXP system software revision is 8.A or later, you can translate the database without first taking any
other action. However, if the DXP software revision is e
t use an 8.A or later
revision of the PCMMI program to upgrade that da
it. If you do not have
this version of the PCMMI program, you can

’communications software program and a data modem
1.5. IUpgrading The DXP Data Base.*’ =---I ’When a DXP contains system software that is at a revision level earlier than 
8.A, you must upgrade that
DXP’s database before you can translate it into a DXP Plus database. To do this, employ an XMODEM
data communications program to store the database on a magnetic diskette or on your computer’s hard
drive. Then employ a revision 8.A or later PCMMI program (obtainable from Comdial’s bulletin board
service) to restore the database and save it to a new file. Restoring the database with this revision 8.A or
later PCMMI program upgrades the database so that it will translate into a DXP Plus database.Remember, the saved database includes the following data: system information, station parameters, line
parameters, toll restriction and automatic route selection parameters, and system speed dial numbers but
does not include the 
SMDA/SMDR records. If you need these SMDA/SMDR records, you must make a
printout of them before you perform the database storage. This is necessary because this procedure does
not record the stored records and they will be lost.1-6 General Programming Information 
						

							Saving the DXP Dafabase
NOTE: This programming procedure details steps that one follows when using the communications software
program known as PROCOMM (produced by Datastorm Technologies). If you are using a different
communications software, your steps may be different.

8.Type the prompted number to choose XMODEM protocol.
9.Install a formatted diskette in the PC’s floppy disk drive or determine a directory location on the
PC’s hard drive. Use this diskette or hard drive directory space as the original DXP database storage
area.10. Type a DOS file name of your choice for the database storage file, and press ENTER. Database save
is automatic; however, depending upon the baud rate, the down load may take 5-25 minutes.
Restoring The DXP Database
1.Load the revision 8.A or later PCMMI program (that you obtained from the Comdial bulletin board
service) into your PC, and start the program.
2.If the saved DXP database is on a diskette, install the diskette in your PC floppy disk drive.
3.Press CONTROL T for the main menu.
4.From the main menu, select system and press ENTER.
5.From the system menu, select save/restore database menu and press ENTER.
6.Type the item number for restore database and press ENTER,
7.Type the path location and the DOS file name for the saved database and press ENTER. Database
restore is automatic. When finished, the system displays the message: transfer complete, no errors.
8.Press ESCAPE and repeat steps 4 and 5.
9.Type the item number for restore database and press ENTER,
10. Type a path location and DOS file name of your choice for the restored database and press ENTER.

Reviewing General
Programming Considerations
Since the programming procedure is menu driven, you should consider all \
of the following points.
lThe menu presents a list of selections for your consideration. Each sele\
ction differs in content and
requires a different response.
lWhen you respond to each selection, it either causes the system to prese\
nt a further breakdown of
selections or causes a particular programming action to take place.
lMenu lines prompt you for the required response and, where appropriate, \
will repeat prompts to
allow programming of more than one device without you having to make ano\
ther menu selection.
lAll of the menus operate in a similar manner. They differ in only the re\
quired response that you
must make.
lSome menus contain more than one page. On these menus, you can press and\
 hold the CONTROL
key while you type the 
N key to display the next page (or type  P to display the previous page).
lEach prompt requires a response followed by a Carriage Return (RETURN)\
. A more common label
for this control on most PC keyboards is  ENTER.
lMost menu responses usually consists of a one-, two-, or three-digit num\
ber or a string of numbers
(or alpha-numeric characters when programming names and messages). Suc\
cessive entries are
separated by a space or a comma (n n n or n,nn,nnn) while blocks of nu\
mbers are indicated by
hyphen (n-nnn).
lShould programmers introduce a numbering conflict while renumbering a fe\
ature dialing code, thesystem will prompt them to remove the conflict. They may have to renumbe\
r several features to
completely clear any conflicting numbers.

Understanding Keyboard And
Terminal Definrtions
3.1Reviewing The Keyboard Definitions
The following list describes the functional keys on the keyboard.
l Number keys:Use keys O-9 for selecting menu items, lines of data to edit, orfor editing numeric prompts.
l Alphabetic keys: Use keys A-Z and a-z for entering string information such as
names and messages. Always begin names of stations, lines, and
so forth with a letter or a space.
l ESCAPE key: This key will return you to the previous command prompt and
cancel whatever input was in progress. This action may or may
not cause the previous screen to be redrawn depending on the
current mode. When you enter a change at most of the
programming menus, you must press the ESCAPE key and type
a y followed by the ENTER key to save the change.
lPunctuation and Symbol keys:Except for comma (which is a field delimiter), use the
punctuation and symbols on the keyboard just as you use the
alphabetic keys.
lRETURN or ENTER key:Use this key to terminate the response to a command prompt or
to end the editing of a data field.The system ignores a RETURNwithout any preceding input except when you are editing
database information. During this operation, the RETURN keymoves the cursor to the next vertical editing position
l SPACE BAR:
l Tab Key:
l Question mark (?):
The space bar steps through the choices for program selections
that provide multiple choices.
Use this key during table editing to position the cursor to thenext horizontal editing position.
This key will display any help available concerning the currently
displayed screen.
