GB/T 11592-2011Interface between data terminal equipment (DTE) and data circuit-terminating equipment (DCE) for start-stop transmission services on public data networks (English PDF)

Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard replaces GB/T 11592-1989 "from public data networks of data terminal equipment/stop transmission services (DTE) and data Interface circuit-terminating equipment (DCE) between. " this standard and GB/T 11592-1989/ITU-TX.20. 1984 compared to the main changes are as follows.

--- The content of Chapter 7 of the present standard of editorial changes were made, and added 7.2 and 7.3;

Appendix F --- the content of editorial changes were made, and adds F.2, F.3, F.4, F.5, F.6;

--- Appendix G for the content of editorial changes were made, and adds G.1, G.3, G.5, G.6, G.7.

This standard uses the translation method is equivalent to using ITU-TX.20. 1988 "public data from/to data terminal transmission services provided Equipment (DTE) and data circuit-terminating Interface "Equipment (DCE) between (in English).

Introduction

CCITT (now ITU-T) taking into account.

a) ITU-TX.1 and ITU-TX.2 specifies provided by a public data network services and service facilities;

b) ITU-TX.92 specifies the hypothetical reference public synchronous data networks using the connections;

c) ITU-TX.96 defines call progress signals;

d) recommendations concerning the provisions of interface elements must be defined in accordance with the hierarchy;

e) public data networks of the interface characteristics between DTE and DCE need to be standardized.

Therefore, unanimously declared. public data networks using the service type start-stop transmission, the interface between the DTE and DCE which should be consistent Provisions of this standard.

Public data from/to data transmission services Terminal Equipment (DTE) and data circuit terminating Interface Equipment (DCE) between

1 Scope

The standard provides a common interface between the DTE and DCE in from ITU-TX.1 defined using the/stop transmission between the user traffic categories Physical characteristics and call control procedures, including the selection of call format and protocol information and DCE provided, comprising a two-way operation Provisions.
