The following table explains the terminology associated with the containment tree.
Term Description
containment
tree
The containment tree represents the hierarchical structure of the Crocus CNV. It is
composed of a number of objects that are ordered in a tree. This tree resembles a
Windows
®
directory structure:
• it is also a levelled structure, with nodes which can be expanded or reduced
• the containment tree objects can be compared with file folders
• the objects contain attributes like file folders contain files.
object An object represents a physical interface, an application or a combination of both.
Each object has its own set of attributes.
Example:
The top object crocusIfConv<2m/Nx64><Tt/Cv> contains the sub object g703OnBoard. This
object contains all the attributes concerning the onboard G703 interface. E.g. the
configuration attribute coding.
attribute An attribute is a parameter related to a certain object. It has a certain value.
Example:
The top object crocusIfConv<2m/Nx64><Tt/Cv> contains the bootFromFlash attribute, which
has the values auto, flash1 and flash2.
value An attribute has a certain value which is …
• changeable in case of a configuration attribute (provided you have write access)
• read only in case of a status, performance and alarm attribute.
Example:
The configuration attribute bootFromFlash can be set to the value auto, flash1 and flash2.
structured value Some attribute values contain underlying values: a structured value. These values
are displayed in the structured value window. If an attribute contains structured
values then a bit string, <Table> or <Struct> is displayed after the attribute.
Example:
The alarmLevel attribute contains a structured value which displays alarms and their
corresponding priority level.
group Groups assemble a set of attributes related by functionality. There are four groups
in TMA, which correspond with the four tabs in the attribute window:
• configuration
• status
• performance
• alarms.
action A group in combination with an object may have actions assigned to them. These
actions are displayed in the action window.
Example:
The Cold Boot action only appears when the top object crocusIfConv<2m/Nx64><Tt/Cv> is
selected in combination with the group Configuration.
