適用范圍：This Functional Standard defines the provision of the OSI connection-mode transport service between two end systems connected to a CSMA/CO LAN. The use of this profile is restricted to a single LAN.A system that supports only the protocol set for layers 1 to 4 specified in this Functional Standard does not satisfy the conformity requirements for the transport layer defined in ISO/DIS 8073, nor does it satisfy the conformity requirements for the network layer defined in ISO/DIS 8473.This Functional Standard specifies a set of protocols, termed a profile, to provide the function defined above. It does not specify total system capability. In particular a system may operate this profile and at the same time engage in other Communications over the medium to which it is connected. The requirements placed on a system in this Functional Standard are solely those necessary for operation of the protocol set specified.Note: Both Functional Standards ENV 41 101 and ENV 41 102 can be applied tosingle LAN environments. Preference should be given to ENV 41 102 in such cases where extensibility of a configuration is to be envisaged.
