3.1 FAULT MANAGEMENT
Fault Management is responsible for detecting, isolating, and reporting anomalous conditions affecting network
operation. Central to the concept of a fault is the fact that some corrective action must be taken, whether automatically over a
Local Area Network (LAN) or by manual intervention by technicians at a site.
The following features are available through Fault Management:
Fault Notification EDACS platforms send all alarm and status event information to a central point. The
Network Manager can periodically poll remote devices for missed events. Events are
logged at the EDACS Network Manager and displayed on the Hierarchical map.
Popup messages or automatic notification actions, such as email, are customizable.
Hierarchical Network
Map for Fault
Notification Each Network Management Station is provided a consistent, integrated view of the
alarm status of its entire EDACS network. Alarms are propagated from lower network
layers all the way up to the top-level map.
Alarm Help On-line help is provided describing the fault and, where possible, suggesting the
corrective action. In addition, to the EDACS-provided alarm information, site-specific
alarm help/corrective action suggestions are customizable.
Alarm Log/Reports A report can be generated listing the past and present alarms.
3.2 CONFIGURATION MANAGEMENT
Configuration Management is responsible for identifying and controlling the state of elements within the network,
including subscriber access to the services provided by the network. This management area performs the following:
•
Using a local client Graphical User Interface to configure a device.
•
Using a Telnet session to configure devices in their native format.
•
Reboot, Restart, or Shutdown certain EDACS devices.
Configuration control of the CEC/IMC is through the CEC/IMC Manager for Windows NT. The CEC/IMC Manager for
Windows NT employs the client-server paradigm. The server, which interfaces to the CEC/IMC, runs on the Windows NT
platform while the client may run on either the Windows NT platform or the EDACS Network Manager UNIX platform.
This allows the CEC/IMC Manager user interface to be run either on the EDACS Network Manager or on the CEC/IMC
Manager PC.
Configuration Management of other devices is via native access i.e., Telnet session into the System Manager, BCU/CAL,
and PI. Each device retains its password protection, therefore users must have login privileges. The ability to log in to
multiple platforms and operate in their native modes from one terminal provides a migration path for devices converting to the
client-server paradigm.
Remote ability to perform shutdown, restart, and reboot operations to selected EDACS devices is provided. The
execution of these actions is recorded in the same log used for alarms.
3.3 ACCOUNTING MANAGEMENT
Accounting Management is responsible for capturing the usage of network resources by end users.
Billing subsystems are available on the BCU (stand-alone), BCU option on the PI platform, and Enhanced Local
Interconnect (ELI). Only the BCU and PI are accessible from the EDACS Network Manager (via File Transfer Protocol) to
retrieve billing records.
