| Abstract | In this paper, radio relay systems for Synchronous Digital Hierarchy (SDH)-based networks with path type Synchronous transfer Module of order 0 (STM-0) without protection switching and with 1+1 switching configuration as said in Recommendation ITU-R F.750 are considered. Byte Interleaved Parity (BIP) codes are used for error monitoring. Rain causes fading and the blocks are received in errors because of this fading and the SES may occur because of these errored blocks and the system may arrive in unavailable state. In this paper, the unavailability ratios of these two systems are calculated and the results are compared with the objectives in Recommendation ITU-R P.1703 and it is assumed that the link comprises the access portion of a network and forms a part of a national portion of a constant bit rat digital path element. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
