EM Objects and Interfaces
The EM manages both physical and logical objects as follows:
•Physical—Represents tangible components and devices such as the chassis (hardware frame),
module interfaces and port adapters, and interfaces
•Logical—Represents intangible, more abstract features, such as ATM connections objects and
profiles
Fault, Configuration, Accounting, Performance, and Security (FCAPS) windows are accessible on both
physical and logical EM objects, in the form of FCAPS menu options that appear when you right–click
on any object in the EM. FCAPS functionality provides a complete management interface to features of
the router.
The EM uses Telecom Graphics Objects (TGO) in the Map Viewer application. TGO is a
TeleManagement Forum (TMF) sponsored initiative to provide standard graphical representations for
network topology maps.
A TGO displays additional information icons on top of the existing object icons displayed in Map
Viewer. The additional icons indicate a variety of information (for example, information on the state of
the object or event status information). The following figure provides an example of a TGO.
Figure1-3 Sample Telecom Graphical Object
An object is a representation of a network element. For example, the object could be a node, a shelf, a
shelf item, or a link. Each object shown in the right window provides pictorial cues which provide
information about its associated network element. The information can be structural information; for
example, a network element name or state and event information such as “out of service.”
Each object can display the following information about its associated network element:
•Object name—Name that the user gives to the object
•Object class—Class indicates a different kind of element
•Object state—(ANSI T1-232):
–
Event unacknowledged count
–
Event unacknowledged state
–
Event outstanding state
The following figure shows an example of a chassis map displaying a few of the TGO icons that could
appear.
