Description
The containment tree represents the hierarchical structure of the Crocus SHDSL G703.
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.
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 crocusShdslTtRpG703 contains the sub object line. On its turn, the sub object
line contains the sub object linePair [1]. This object contains all the attributes concerning the
line pair. E.g. the status attribute lineAttenuation (dB).
An attribute is a parameter related to a certain object. It has a certain value.
Example:
The object line contains the attribute channel, which has the values central and remote.
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 channel can be set to the value central or remote.
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, or is displayed after the attribute.
Example:
The alarmLevel attribute contains a structured value which displays alarms and their corresponding
priority level.
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.
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 crocusShdslTtRpG703 is selected in
combination with the group Configuration.
