STM-1 FOTE: 21 Nos. (Belongs to Group 1 of Network Layout) + 100% additional 

capacity, graphical network view, 2 concurrent users shall be supplied under this 

package by the bidder. The NMS server hardware should have dual hard disks 

configured as a RAID system level 1 (mirroring). 

There should be a possibility to add a second NMS server to create a 

Main/Standby system using an interconnecting link with a minimum bandwidth of 

2Mbit/s. The Standby should automatically switch to active mode if it looses 

contact to the Main. It shall also be possible to operate the two NMS independently 

if the connection between the two servers is down. 

For quick fault recovery and minimum NMS downtime it shall be possible to 

manually create a backup of the database and store it on the local disk or on a 

DVDs. A facility should exist to create a bootable backup of the complete system 

either on tape or DVDs.

For ease of management and monitoring by GETCO, the System shall be able to 

manage all the offered communication equipment (SDH/PDH) and Teleprotection 

equipment from a single software and hardware. 

d) Graphical User Interface 

The Graphical User Interface should have definable network displays (maps). Icons 

symbolizing sub-networks, equipment and links are to be placed on an optional 

background image and can be opened to display greater details down to equipment 

port level. Context sensitive menus and online help should be available. It should be 

possible to create any number of network maps to create different views of the 

network, e.g. geographical, schematic, sub-network, etc.

2.6.3 Management Functions 

The NMS shall support following Management functions: 

2.6.3.1 Configuration Management 

Configuration management is concerned with management, display, and control of the 

network configuration. Minimum specific requirements that shall be satisfied include the 

following: 



Page 38 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 



Page 39 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. 



Page 40 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 



Page 41 of 60



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.
