Table 3-4. DSL Circuit Alarms in Order of Severity
State Indicator Description
Normal – 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.
Not Occupied / No unit is installed in the slot, or the unit is not recognized.
Alarms Disabled D Alarm reporting has been disabled for this circuit at the EMU-830. This can be
changed using selection 2 from the Main menu.
Not Manageable X The DSL card in the slot does not support centralized management by the
EMU-830.
NTU/STU-R N 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
