| Abstract | Packet-switched based Telecommunication services are es sential to a competitive ISDN service offering and FRANCE TELECOM is now enhancing NUMERIS, the French ISDN, to introduce improved packet switched data communication capa bilities on both the B and the D channels of the user access. This is made possible on the basis of the development of a Packet Access Point equipment which will give access to packet switch ingfacilities and ofFrame Handlingfunctions within ISDN local erxhanges. Thispaperdescribes the mainfeatures of these developments andfocusses on the implementation offrame handlingfunctions in the ALCATEL EI0 switching system which have been used to support the digitalization of the french network, thus allowing a quick evolution to ISDN with a rapid deployment of newfeatures throughout the national network. After describing the nationally defined interface between the frame handler of the local ex changes and various Access Points (referred lo as IheAPI) which may be reached via the D channel of the user access, the paper shows the benefits and the new applications users may gain finom these features and then discusses further evolutions currently under consideration for the NUMENS network architecture and for the packet switched based data communication services. |

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.
