| Abstract | A brief review of Swiss PTT history shows that a number of switching systems have been introduced over the years. This problem of inhomogeneity shall be overcome in the future by a unique all digital PCM telephone network currently being developed which will be introduced gradually in the 1980's. Transmission systems will use more minicoaxial cables for carrier-as well as PCM-systems. A special PCM transmission system network which will reach the major cities will provide data transmission service for channels up to 48/64 kbit/s. This early data network shall be combined later with the PCM telephone network. |

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.
