ADC EMU-830 user manual DSL Line Unit Status Conditions State Indicator Description

Chapter 3: Provisioning						September 25, 2006
				Table 3-3. DSL Line Unit Status Conditions
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
				menu to view the alarm status.
Both loops		*		The indicated alarm involves both loops.
Alarm		Alarm		The most severe active alarm in the circuit is shown.
