27、 (dow)1996-02-15EN60870-6-601:1995 BSI 11-1999 3 Introduction This section of IEC870-6 defines functional profiles to be used in telecommunication networks for electric power systems. It is largely based on existing ISO/IEC International Standards and International Standardized Profiles (ISP). The n

28、otion of Functional Profile is fundamental in the organization of IEC870-6. A description of Functional Profiles, their classification scheme, and the manner of defining them are laid down in Part6, Section1. The present section is a Transport-class Profile providing the COnnection-mode Transport Se

29、rvice(COTS) over the COnnection-mode Network Service (CONS) for the specific case of permanent access to a Packet Switched Data Network (PSDN). ISO defined a multi-part ISP for specification of COTS over CONS or CLNS profiles: the ISP10609. In the ISO taxonomy, it corresponds to Transport Profiles T

30、B1111 for analog permanent access and TB1121 for digital permanent access to a PSDN. It makes frequent reference to the International Standardized Profiles ISO/IEC ISP10609-1, ISO/IEC ISP10609-5 and ISO/IEC ISP10609-9. 1 Scope This Functional Profile (FP) defines the provision of the OSI Connection-

31、mode Transport Service between an End System (“The Reference End System”) which uses a Permanent Analog or Digital Circuit to access a Packet Switched Data Network (PSDN) and another End System (“The Compatible End System”) which is accessible, by permanent or switched methods, either directly from

32、the same PSDN, or indirectly through the provided OSI Connection-mode Network Service. This FP also defines the provision of the OSI Connection-mode Network Service between the Reference End System and the Compatible End System using the X.25 subnetwork procedures to aPSDN. This FP is applicable to

33、environments which support the OSI Network Service. In the ISO taxonomy four options are defined as a function of the transport protocol classes operated: Implementation of the option TD (class0 only) requires that the End System does not operate any of the multiplexing classes (class2,3, or4) of th

34、e Transport Protocol procedures. Such End Systems will only interwork with End Systems that also implement class0 Transport Protocol procedures. Implementation of the other options (groups TB, TC, TE) in one End System, enables that End System to interwork with any End System conforming to ISO8073.

35、This FP recommends the implementation of classes0,2 and4 in End Systems. In the ISO taxonomy such End Systems with permanent access to a PSDN are referenced with profiles TB1111 (foranalog access) orTB1121 (for digital access). NOTEThe FP specifies a set of protocols to be used in the Reference End

36、System in order to provide the function defined above. It does not specify total End System capability. Therequirements placed on an End System in this section of IEC870-6 are solely those necessary for operation of the protocol set specified. The format of this section is in conjunction with one of

37、 the ISO/IEC ISPs. These ISPs are defined in a multi-part way. For example, to define the profiles TB1111 and TB1121, the present section refers to the three different ISO/IEC ISPs, listed in clause2. When applicable the present section follows ISO/IEC ISP10609-1, ISO/IEC ISP10609-5 and ISO/IEC ISP1

38、0609-9. The present section defines some complementary specifications to ISP10609. Thosespecifications mainly concern the priority management and the transport class negotiation. Group TB: includes transport protocol classes0,2 and4, Group TC: includes transport protocol classes0 and2, Group TD: inc

39、ludes transport protocol class0, Group TE: includes transport protocol class2.EN60870-6-601:1995 4 BSI 11-1999 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this section of IEC870-6.
