• Network configuration, Operation and Performance Management. • Maintenance Tasks. The operation and Maintenance functions are based on the concepts of the Telecommunication Management Network (TMN), which is standardized in the ITU-T series M.30. Following is the figure, which shows how OMC system covers all the GSM elements. The OSS is the functional entity from which the network operator monitors and controls the system.

An important function of OSS is to provide a network overview and support the maintenance activities of different operation and maintenance organizations.

Introduction Before the initial 1970s, most of the support activities in a telephone company such as taking orders, maintaining network inventory, provisioning services (for example, line assignment and testing), configuring network components, managing faults and collecting payments were performed manually. It was realized that many of these activities could be replaced by computers. In the next few years, a number of computer systems and software applications were created to automate these activities. Examples include TIRKS, RMAS, SES, etc. Thus came the term Operations Support Systems (OSS).

The article explains some of the basic functions of these systems. However, this article doesn't intend to provide extensive details. For an extensive overview of business activities, business process and functions, refer to standards such as eTOM and TAM. 2. The Realm of OSS/BSS in Order Fulfillment, Assurance and Billing 2.1 Order Fulfillment Communications products/services could range from Voice services to IP and Data services to Hosting and CPE services.
