Information technology. Framework for protocol identification and encapsulation1 Scope In a layered approach to protocol architecture, protocols have a relationship to one another such that a protocol at layer (n) uses the services of the layer below it the (n 1) services which, in turn, are provided by a layer (n 1) protocol. One of the services used by a layer (n) protocol is the encapsulation of its (n) Protocol Data Units (PDUs) in a way which is transparent to it. Such encapsulation is realized by the carriage of the (n)

Due to its strength

BS EN ISO 6506-3 supersedes BS EN ISO 6506-3:1999 which is withdrawn

obturator in the closed position

This document defines the interfaces and gives guidance for the design of systems and procedures for change of track gauge

BS 7430 also defines selection parameters for the earthing arrangements and makes clear the need for careful consideration of various site conditions such as soil composition and resistivity
