Abstract: The Integrated Services Digital Network (ISDN) offers on-demand switched end-to-end digital connectivity over a wide area, enabling the integration of both voice and data services over a common core network. The role of ISDN in data networking act as both the core of the transport network and data network technologies with enhancing resilience in a mixed-technology data solution, complementing other data networks. The implementation of the ISDN in most advanced nations of the world marks as the beginning to the end of the traditional piecemeal approach to developments in communication networks ISDN, which is a product of digital technology, aims to integrate the existing disparate networks into a single electronic highway for the combined transport of information in a multiplicity of formats while the provision of services on a single line sounds ideal for the business environment. The main thrust in ISDN, coming from a technological push rather than the market by pull many potential customers are skeptical about the usefulness of the ISDN service for a number of reasons such as cost, standardization problems and the need to upgrade existing hardware. The issues associated with data transport based an ISDN solution which considered and include security, bandwidth utilization, scalability and the management of ISDN-attached devices. Optimising the use of ISDN networks for supporting the most prevalent routed and routing protocols.
