With rapid evolution of technology in digital transmission systems, the dedicated transmission system networks for Oil & Gas pipelines have also been evolving and benefit immensely. These evolutions in dedicated transmission networks (DNW) have fulfilled different types of functional requirements for Operations and Maintenance of pipelines..

The advances in technology and compactness of transmission equipmen t has resulte d in Nex t Generation SDH transmission equipment with Multiple Services Provisioning capability such as TDM, ATM and Ethernet, which is also called as MSPP equipment (Multiple Service Provisionin g Platform).
