NE Configuration

Once an NE is discovered by the NMS its configuration shall be automatically uploadedand stored on the NMS hard disk. It shall be possible to configure the NMS toautomatically keep a definable number of the most recent NE configurations accessiblefor inspection and/or download. All NE configuration changes should be done from theNMS using easy to use graphical windows accessible via drop down menus startingfrom the NE symbol on the graphical network view. The NMS shall fully support the

2.6.3.2 Fault Management






of 60

The Network Management System should provide comprehensive and efficient faultmanagement, based on a graphical network view and coloured symbols representingthe alarm state of the respective network element.

Fault management is concerned with detecting, diagnosing, bypassing, directingservice restoration, and reporting on all the backbone network equipment, systems,and links. Minimum specific requirements that shall be satisfied include the following:

a. Display equipment status in a consistent fashion regardless of the source of thedata on a graphical topological, map-type display. Status shall be displayedthrough the use of colours on links and nodes as well as through text.

c. Maintain an alarm summary of unacknowledged alarm events on the managementstation display and maintain a log of all received alarms. The operator shall be ableto acknowledge and clear alarms individually and as a group. The use of alarm

correlation techniques is encouraged to minimize the proliferation of alarmscaused by a single, common event. All alarms shall be configurable as criticalalarms, major alarms and minor alarms with different colours

• The NE symbols on the layered network views must have markers to indicate

1. if an NE is reachable,

2. disabled through the operator,

3. has an attached operator note,

4. if there are unacknowledged active alarms (one marker for each severity

level),5. if there are unacknowledged cleared alarms

alarms. The alarm list should be displayed in a tabular form with extensivefiltering possibilities. It must be possible to adjust the size and the order of thedisplayed columns. Alarms are selectable for operator actions (e.g.acknowledgement) individually or in groups using the mouse and the Ctrl or Shift key.

• New active alarms should appear in the alarm list marked as unacknowledgeduntil they are confirmed by the operator. New cleared alarms must be either

marked as unacknowledged or alternatively self-acknowledged by the NMSsoftware. The preferred behavior should be an NMS configuration option.• For each alarm a detailed alarm view must exist to display all alarm properties

including raise and clear times, the time of acknowledgement and theusername of the person which performed the acknowledgment. It must bepossible to add operator notes for each alarm.

• For external equipment with alarm output contacts (common alarm outputs,door contacts etc.) the fault management should provide an option to displaythe respective alarm states by coloured symbols on the map.

• Sections (Links - typically fibre optic interconnection between nodes) should bedynamic and displayed in the colour of the most severe alarm of the ports whichthe link is connected to.






of 60

Synchronization Map

Since this is a large network, to facilitate the identification of synchronization problemswithin the communication network, the NMS should provide a dynamic synchronizationview/map. This synchronization view must display the active synchronization sources

for every network element using a graphical representation, so the clock distribution inthe network can be easily tracked.

2.6.3.3 Security Management

Access to the different functional areas of the NMS shall be strictly controlled by theprivileges assigned to the individual NMS users. Accounts which shall have access tothe NMS must be assigned NMS access rights by an NMS administrator. There shallbe one overall NMS administrator which is able to create additional regionaladministrators which have full control e.g. to assign NMS access rights, but are limitedto their domain – corresponding to e.g. a geographical region.

To simplify the task of access right assignments customer specific user profiles can bepredefined which then can be assigned the individual NMS users. It should allow to create users which have access rights to several/all domains with a different profile for each domain.

Specifically, the following features must be individually assignable to different user classes and/or user accounts:

• Administrative functions such as adding, modifying and deleting NMS user accounts
