PROGRAMMING CONVENTIONS
The Model 748 has 14 menus or screens for programming and system maintenance. Programming
activities include the system and user databases. Maintenance activities include up/down load device
configuration, down load billing data, system monitoring, plus setup and adjustments.
Selecting an item in a menu is done by typing the associated number and pressing
ENTER
. If the
number is out of range or invalid, an error beep will be sent and the line cleared. You can edit the
line by using the backspace key. The Model 748 does not evaluate the number until you press
ENTER . To leave a menu and return to the previous menu, press the ESCAPE key (often labeled
“
ESC
”).
At any time, you can get back to the Main Menu by repeatedly pressing the
ESCAPE
key. To
prevent accidental exiting during modem programming, selecting the exit command is required from
the Main Menu.
Each menu has related commands in it. For example, the System Menu has all of the commands
associated with the system as a whole, while the Interconnect Menu contains additional menus for
specific areas of interconnect operation.
Each menu or screen remains displayed in its entirety while you are working with it. Each time you
change an item, it is immediately updated on the screen. This gives you an up to date view of all the
data on the screen at once. An example would be when programming a user. All the programmable
items for that user is displayed on a single screen. You can see at a glance all the current program
settings for that user. This makes for less errors or confusion due to the lack of displayed
information.
There are three ways of entering data/parameters in the Model 748. The first is numerical data,
(timing value or user number) this is entered as a decimal number. The second is string data, (ANIs,
Autodials, or Selcall codes) this is entered in alpha-numeric strings. The third type is via scrolling or
toggling among (state, type or mode) options for that parameter.
Numerical data is displayed in the units of measure for that data. When changing numerical data,
you enter data using the same units of measure.
A valid data range for that data will be displayed. The Model 748 will “BEEP” if the data entered is
out of range. Pressing
ENTER
without entering any data will not change the current value. The data
on the screen will be updated immediately once you have pressed ENTER .
When programming string data (ANI, pager codes), not all characters may be valid. Any invalid
characters simply won't be recognized when entered. Once the maximum valid characters have been
entered, no more will be accepted. Pressing
ENTER without entering any data will not change the
current value. The data on the screen will be updated immediately once you have pressed
ENTER
.
String type data can be cleared by pressing the space bar and then pressing ENTER .
When programming by scrolling (by pressing the space bar) through the (state, type or mode)
selection for a particular item, the selection will be displayed in plain English (something descriptive
for that item). You can accept the currently displayed selection by pressing
ENTER . If you go past
