Table 3-3. DSL Line Unit Status Conditions

The circuit has no active alarms. This can be because one or more of the
circuit's alarms are disabled from being reported at the DSL card.
No unit is installed in the slot, or the unit is not recognized.
Alarm reporting has been disabled for this circuit at the EMU-830. This can be
changed using selection 2 from the Main menu.
The DSL card in the slot does not support centralized management by the
EMU-830.
The DSL card in the slot is an NTU/STU-R card. Alarms for a circuit with an
NTU/STU-R card residing in the managed shelf are not reported on this screen.
You can, however, login to the NTU/STU-R card using selection 1 from the Main
menu to view the alarm status.
The indicated alarm involves both loops.
The most severe active alarm in the circuit is shown.
