Foreword

This standard is identical with the international standard ISO /IEC 7776.1995 Flat "Information technology - Telecommunications and information exchange senior Number According to the link control procedures X. 25LAPB compatible DTE data link procedures "(in English). This standard replaces GB/T 14399-1993 high-level data link control procedures "Information processing systems - Data communications Chapter 4 describes elements of procedure. Some content is only for basic (modulo 8) operation, some of the content only for expansion (modulo 128) operation. Chapters 5 and 6 describe the single link procedure (SLP) and an optional multilink procedure (MLP). Single link procedure from the frame structure Structure and elements of procedure corollary. SLP is used to exchange data on a single data link, MLP is used for data on a plurality of parallel SLP exchange. If you want the impact of individual SLP failures do not interfere with a higher operation, you need to MLP. By prior bilateral agreement, but also in Use MLP on a single SLP. On the DTE/DCE connection is selected MLP only decide when booking. On the DTE/remote DTE Connection, which is selected by bilateral agreement. In the statutes need to choose between a variety of possible actions in the case, the general gives the recommended choice. Unless specifically stated otherwise, action Choice does not affect interoperability with other embodiments of the present standard, although operational efficiency may be affected. In this option, the impact interoperable The case, made clear that the procedure needs to select with the remote end of the procedure of prior consultation. In order to meet a wide range of application needs and consistent, has Such a choice as far as possible be minimized. The basic requirements of this standard to all embodiments is that they can be according to the provisions of the permit by the standard The remote end of the action taken in response to (pre-agreed procedures involving the exception). Chapter 7 contains the static conformance requirements Dynamic conformance requirements and the Protocol Implementation Conformance Statement (PICS).
