INTERFACE (DSX-1) > CONFIG > LINE CODE
This setting must match the line code of the circuit to which the interface is connected. Choices are B8ZS
(bipolar with 8-zero substitution) and
AMI (alternate mark inversion). The default is B8ZS.
INTERFACES (DSX-1) > STATUS
Displays the DSX-1 interface status including performance data and alarm histories.
INTERFACES (DSX-1) > STATUS > ALARMS
Displays current alarms and alarm history for the DSX-1 interface.
INTERFACES (DSX-1) > STATUS > ALARMS > CURRENT ALARMS
Displays the current alarms on the DSX-1 interface. An asterisk in a field indicates that an alarm is active.
INTERFACES (DSX-1) > 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-1) > Status > Alarms > Current
Alarms for more details on listed alarm conditions.
INTERFACES (DSX-1) > STATUS > ALARMS > CLEAR HISTORY
Selecting this activator will clear the Alarm History for the T1 interface.
INTERFACES (DSX-1) > TEST
These options are used to initiate local and remote loopback tests and display the test status.
INTERFACES (DSX-1) > TEST > SLOT
Displays the slot number of the installed DSX-1 Module.
INTERFACES (DSX-1) > 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 CARD) > 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).
