Circuit List Screens
4.4.1
Circuits in Alarm
The Circuits in Alarm screen (
similar to Screen 4-3
) dis-
plays a list of all circuits which currently are in an alarm
condition. Not that any 1558A units that have been placed in
an Out of Service or Unused state do not report alarms.
Only 1558A units that are in an In Service state and are in
alarm will be posted to the Circuits in Alarm display.
4.4.2
Circuits in Test
The Circuits in Test screen (
similar to Screen 4-3
) displays
a list of all circuits which currently are in test mode. A cir-
cuit 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. Refer to
Section 4.2.6
for details concerning
operations within this screen.
4.4.3
Circuit List
The Circuit List Screen (
Screen 4-3
) lists all circuits known
to the 1559.
4.4.4
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.
NOTE: 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 1558A units are assigned address starting with shelf 1,
position 1, 2, 3, etc. The factory default address setting of a
1558A is shelf 1, position 1 (1.01). Additional information
concerning the unit address is discussed in the Installation
sections of this manual.
State: The current state of the circuit has the following pos-
sible definitions:
Unused: The circuit has never been installed or config-
ured.
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
line is the circuit name assigned by the user for the NET B
T1 facility. Circuit names are defined by the user with the
Configuration menu (
Screen 4 -7 on page 4-8
).
Near: This field shows the current status of a protected
span’s two T1 lines as viewed from the 1558A unit. This
status is derived from the number (or absence) of errors in
the received data and from the status of the protection
switch at the CO. The top line in the field depicts the status
of Line A. The second line depicts the status of Line B. This
