What is the use of a trunk system in the Operations Support System for Network Transmission?

A. It is used for planning and implementation of adequate facilities for traffic to be handled without being blocked
B. It is used to change operations system, as it is also used to control the network and network elements
C. It is used to monitor the loss and signal-to-nosie ratio in the trunk transmission system in bell system
D. It is used to make network management system interoperable

Explanation: The trunk test system is used to monitor the loss and signal-to-noise ratio in the trunk transmission system in Bell System. A trunk is a logical entity linking two switching offices.

TMN had been developed based on ________ management principles.

A. Osi
B. Itu
C. Ieee
D. Iete

Explanation: TMN is necessary to extend the private and proprietary, but well-developed network management systems, and make them interoperable. It is to be kept in mind that TMN had been developed based on OSI management principles.

It is not necessary for a trunk to meet the minimum criteria set for quality control.

A. True
B. False
C.
D.

Explanation: A logical entity, used to link two switching offices is known as Trunk. Each and every trunk in the network is inspected for their quality check. It is extremely necessary that a trunk qualifies the minimum criteria set for quality control otherwise they are removed from service.

The operations systems in the OAMP of telecommunication network are part of the telecommunications network management activities and fall under the ________ function of the network management.

A. Performance management
B. Fault management
C. Security management
D. Configuration management

Explanation: The role of operations systems in the OAMP of telecommunication network is crucial. They are part of the telecommunications network management activities and fall under the performance management function of the network management that is defined under the OSI model.

In function blocks, when a Web browser interfaces with a Web-based management system it is accessing an x-reference point.

A. True
B. False
C.
D.

Explanation: The function blocks in are connected with interfaces designated by x, q3, qx and f. When a Web browser interfaces with a Web-based management system it is accessing an f-reference point. When a network management system automatically creates a trouble ticket in a trouble tracking system, it is communicating via an x-reference point.

The TMN _______ provides an interface between human personnel and TMN activities.

A. Osf
B. Wsf
C. Mf
D. Qaf

Explanation: M.3010 defines TMN architecture made up of five function blocks: operations systems function, network element function (NBF), mediation function (Mf), workstation function (WSF), and Q-adapter function (QAF). The TMN WSF provides an interface between human personnel and TMN activities. More specifically, this function addresses the presentation aspect.

An interface between a management agent embedded in a network element and a network management system will be a _____ reference point.

A. Q3
B. X
C. Qx
D. F

Explanation: The function blocks in are connected with interfaces designated by x, q3, qx, and f. These are called TMN service interfaces or simply, TNM interfaces. An interface between a management agent embedded in a network element and a network management system will be a q3 reference point.

Information models specified by SNMP and OSI management deal with the management of network managers.

A. True
B. False
C.
D.

Explanation: Information models specified by SNMP and OSI management deal with the management of network elements. The TMN information model has been used in specific technology such as ATM and SDH/SONET.

________ is used by the performance management application to gather traffic statistics, by the configuration system to discover and delete network elements, and by the fault management system to gather errored-seconds on unstable elements.

A. Function blocks
B. Physical architecture
C. Physical blocks
D. Information architecture

Explanation: Function blocks are designed to be non-overlapping. This could be used by the performance management application to gather traffic statistics, by the configuration system to discover and delete network elements, and by the fault management system to gather errored-seconds on unstable elements.
