Once the user has booted the LAPS software and connected
the PC to the SUPV port of the 1558D unit, the Log On
screen will appear on the PC display (see Figure 4-2). To
access the LAPS user menus, press the <Enter> key. The
LAPS system responds by displaying the LAPS Main Menu.
(see Figure 4-3).
Main Menu Screen
The Main Menu lists the main functions that the user can
select and access. The primary user interfaces are shown in
the Menu Tree (Figure 4-1 on page 4-1) and the Main
Menu screen (Figure 4-3 on page 4-2). Use the terminal
arrow keys or cursor control commands to highlight the
desired submenu. Once a selection has been made, press
<enter> to activate it. Refer to the cursor control commands
detailed in Cursor Controls on page 2-2.
The Main Menu and any subsequent sub menu may be
exited by pressing <esc>. If the Main Menu is exited, LAPS
returns the user back to the Log On screen. This is a valid
way to end a user session. If any other menu is exited, the
user is returned to the previous screen. The following sec-
tions discuss the key user submenus and their uses.
Circuit List Screens
Circuits in Alarm
The Circuits in Alarm screen displays a list of all circuits
which currently are in an alarm condition. Not that any
1558D units that have been placed in an Out of Service or
Unused state do not report alarms. Only 1558D units that
are in an In Service state and are in alarm will be posted to
the Circuits in Alarm display.
Circuits in Test
The Circuits in Test screen displays a list of all circuits
which currently are in test mode. A circuit is deemed to be
in test mode if it has any kind of a loop established. Circuits
do not have to be “In Service’ to be in test mode.
Circuit List
The Circuit List screen (Figure 4-4) lists all circuits known
to the 1559 and their Near and Far operational statuses.
Circuit List Screen Manipulation
The three screens involving a circuit list (Circuits in Alarm,
Circuits in Test, and Circuit List) are all displayed and
manipulated in the same manner. Each circuit’s identifica-
tion and status is displayed using the following fields.
Pressing the <esc> key will take the user back to
the previous circuit list screen.
Pos: This field specifies the circuit’s unit address. Stand
alone 1558D units are assigned address starting with shelf 1,
position 1, 2, 3, etc. The factory default address setting of a
1558D is shelf 1, position 1 (1.01). Additional information
concerning the unit address is discussed in the Installation
sections of this manual beginning on page 2-1.
State: The current state of the circuit has the following pos-
sible definitions:
Unused: The circuit has never been installed or con-
figured.
Out Service: The circuit has been: 1) manually taken out
of active service, 2) installed but never put
into service, or 3) configured but never
installed.
In Service: The circuit has been installed and configured
and is currently in use.
Circuit ID: The first line in this field is the circuit name
assigned by the user for the NET A T1 facility. The second
