INTERFACES (DSX) > STATUS > ALARMS
Displays current alarms and alarm history for the integrated DSX interface.
INTERFACES (DSX) > STATUS > ALARMS > CURRENT ALARMS
Displays the current alarms on the T1 interface. An asterisk in a field indicates that an alarm is active.
INTERFACES (DSX) > STATUS > ALARMS > ALARM HISTORY
Displays the alarm history for the T1 interface. An asterisk in a field indicates that an alarm has occurred
on the T1 interface since the last clear history. Refer to Interfaces (DSX) > Status > Alarms > Current
Alarms for more details on listed alarm conditions.
INTERFACES (DSX) > STATUS > ALARMS > CLEAR HISTORY
Selecting this activator will clear the Alarm History for the integrated DSX interface.
INTERFACES (DSX) > STATUS > RX LEVEL
Displays the level (in dB) of the received T1 signal on the interface.
INTERFACES (DSX) > TEST
These options are used to initiate local and remote loopback tests and display the test status.
INTERFACES (DSX) > TEST > LOC LB
Loopback of the local unit. Choices are NONE, LINE, AND PAYLOAD. LINE loopback loops all of the received
data back toward the network. The transmitted data is the identical line code that was received, including
any bipolar violations.
PAYLOAD loopback is similar to line loopback except that the framing is extracted
from the received data and then regenerated for the transmitted data.
NONE disables the loopback test.
Default is
NONE.
INTERFACES (DSX) > TEST > REM LB
Loopback of remote unit. Choices are NONE, LINE, and PAYLOAD. LINE loopback loops all of the received
data back toward the network. The transmitted data is the identical line code that was received, including
any bipolar violations.
PAYLOAD loopback is similar to line loopback except that the framing is extracted
from the received data and then regenerated for the transmitted data.
NONE disables the loopback test.
Default is
NONE.
INTERFACES (DSX) > TEST > TEST STATUS
Indicates whether a test is in progress.
LOS Loss of Signal. No signal detected on port interface.
RED
Not able to frame data received on the port.
Alternately referred to as Out of Frame (OOF).
YELLOW Remote alarm indicator (RAI) being received on port.
BLUE
Receiving unframed all ones from the port alarm
indicator signal (AIS).
