Base element states
JViews TGO provides a
comprehensive and user-friendly graphical environment for network
states and components, as well as for the alarms detected by the
supervisory system (network management application).
For full details about states, refer to States.
In most cases, telecom equipment is in one
of the following three fundamental states:
- Out Of Service (OOS)
- In service but carrying No Traffic (NT)
- In service and Carrying Traffic (CT)
These states may be named differently
depending on the telecom standard used, but these three
fundamental states appear in the main state models.
States are represented graphically through
a base element. The following figure shows a network management
workstation in the three fundamental states.

State modifiers
The other states introduced by the various state models are
represented by icons placed at the base of the telecom object.
These icons, called modifiers,
enhance the visual representation provided by the base state. The
following figure illustrates how state modifiers placed on a
network element and on a link are displayed.

Alarm states
A number of graphical properties have been
developed to notify the operator of the presence of alarms. When
a new alarm is registered on an element, four visual cues are
added to the graphical representation of the element:
- An alarm counter is displayed in the network element base.
- An alarm balloon appears above the network element displaying another alarm count.
- The object base turns a vibrant color (red, orange, or yellow) according to the severity of the alarm.
- A colored outline is associated with the object base.
The following figure shows a network
element in three different alarm states illustrating the colored
base, the outline, the alarm balloon, and the alarm count.

Details of the alarm color coding scheme and other alarm
characteristics are provided in Alarm states.
