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).
The following topics provide a basic description of the visual aspect of states. For full details about states, refer to section States.
In most cases, telecom equipment is in one of the following three fundamental states:
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. Figure 1.24 shows a network management workstation in the three fundamental states.
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. Figure 1.25 illustrates how state modifiers placed on a network element and on a link are displayed.
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:
Figure 1.26 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.
