of 60

a. Provide tools to establish and maintain the backbone topology and configuration information and provide graphical maps depicting the configurations.

b. Gather descriptive information about the current configuration of the equipment, provide operator displays, and prepare reports.

c. Provide tools for planning, establishing, and changing the static equipment configuration. Provide for changes to the equipment configuration in response to equipment failures, planned upgrades, and operator requests to take equipment offline for testing.

d. Provide verification testing to support new equipment installation.

NMS Configuration A graphical User Interface should exist to create network Domains, the NEs to be managed by the system and NE supervision processes. (Domains are used to structure the network in areas of responsibilities and are used in the definition of access right. The supervision processes allow grouping the NEs for supervision and enabling the supervision of a group of NEs to be turned to ON or OFF.)

NE Configuration Once an NE is discovered by the NMS its configuration shall be automatically uploaded and stored on the NMS hard disk. It shall be possible to configure the NMS to automatically keep a definable number of the most recent NE configurations accessible for inspection and/or download. All NE configuration changes should be done from the NMS using easy to use graphical windows accessible via drop down menus starting from the NE symbol on the graphical network view. The NMS shall fully support the administration of the NE configuration data (upload, download, backup, copy) and the NE embedded software (upgrade).

End to End Circuit/Trail Configuration As an NMS option a facility for automated end-to-end configuration of trails and circuits (trail management) shall be offered including the 64kBit/s cross- connections. The option shall enable the operator to create and maintain database tables containing all the communication services configured into the network. A graphical user interface shall be available to browse, modify or delete the existing end to end connections or to create new ones. To create new connections it shall be sufficient to specify the type of connection, the required bandwidth, the protection type and the two end points. The software should then suggest routes through the network and can be used to automatically download the required cross-connections to all the NEs which belong to the selected route. Trails e.g. at VC4, VC12 or E1 level can be inspected for the number of used/free channels. Various reports shall be printed and information extracted in a format which is suitable to be imported into a spread sheet program such as Excel. 2.6.3.2 Fault Management




of 60

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

Fault management is concerned with detecting, diagnosing, bypassing, directing service 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 the

data on a graphical topological, map-type display. Status shall be displayed through the use of colours on links and nodes as well as through text.

b. Obtain status and detect faults through periodic polling, processing of unsolicited alarms and error events, and periodic testing for connectivity.

c. Maintain an alarm summary of unacknowledged alarm events on the management station display and maintain a log of all received alarms. The operator shall be able to acknowledge and clear alarms individually and as a group. The use of alarm correlation techniques is encouraged to minimize the proliferation of alarms caused by a single, common event. All alarms shall be configurable as critical alarms, major alarms and minor alarms with different colours

Additionally the following fault management features are required:

• 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 • An Alarm Summary View to display alarm counters per severity • An Alarm List containing all active alarms and all cleared and unacknowledged

alarms. The alarm list should be displayed in a tabular form with extensive filtering possibilities. It must be possible to adjust the size and the order of the displayed 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 unacknowledged until they are confirmed by the operator. New cleared alarms must be either marked as unacknowledged or alternatively self-acknowledged by the NMS software. 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 the username of the person which performed the acknowledgment. It must be possible 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 display the respective alarm states by coloured symbols on the map.

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




of 60

Synchronization Map Since this is a large network, to facilitate the identification of synchronization problems within the communication network, the NMS should provide a dynamic synchronization view/map. This synchronization view must display the active synchronization sources for every network element using a graphical representation, so the clock distribution in the 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 the privileges assigned to the individual NMS users. Accounts which shall have access to the NMS must be assigned NMS access rights by an NMS administrator. There shall be one overall NMS administrator which is able to create additional regional administrators which have full control e.g. to assign NMS access rights, but are limited to their domain – corresponding to e.g. a geographical region.

To simplify the task of access right assignments customer specific user profiles can be predefined 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

• Different levels of access rights to the network elements (modify, monitor only, software download)

• Access to individual network elements or groups of network elements (regions) • The right to create and modify network maps • Use function such as Alarm Forwarding, Trail Configuration, etc.

2.6.3.4 Performance Management Performance management is concerned with evaluation of the use of network equipments and their capability to meet performance objectives. Minimum specific requirements that shall be satisfied include the following: a. Provide support for an operator to initiate, collect, and terminate performance

metrics under both normal and degraded conditions. For example, BER of each link, together with other data measured at each node, shall be available on operator request.

b. Monitor point to point & end to end signal quality and history. Provide operator controls to monitor performance of specified events, measures, and resources.

Specifically provide displays to permit the operator to: 1. Select/deselect network equipments, events, and threshold parameters to monitor 2. Set monitoring start time and duration or end time 3. Set monitoring sampling frequency 4. Set/change threshold values on selected performance parameters

5. Generate alarm events when thresholds are exceeded. 6. Set multiple thresholds on certain performance parameters. Alarm categories

include as a minimum a warning and a failure. 7. Calculate selected statistical data to measure performance on selected equipment

based on both current and historical performance data maintained in performance logs. Performance data provided is limited to what is available from the equipment Contractors.

8. Provide graphical displays of point to point and end to end current performance parameter values. Provide tabular displays of current, peak, and average values for performance parameters.

9. Generate reports on a daily, weekly, monthly, and yearly basis containing system statistics.

15 Minute and 24 hour Performance counters according to G.826 must be collected and stored on the NEs for a limited time. As an NMS option a function shall be available to cyclically collect these counters from the NEs and store them on the hard disk in XML format. The operator shall be able to specifically define which individual data collection points on which equipment shall be included in the collected data sets.

2.6.3.5 Interfaces to external systems As a future option, to provide the possibility to send data to other NMS or to support additional non native equipment the system should support two open software interfaces, one to export data to external systems (northbound interface) and a second one to be able to feed basic equipment and alarm data to the NMS from external customer specific software (southbound interface).
