Foreword

This standard is equivalent to international standards ISO 4903. 1989 "Information technology - Data communication - 15 pin DTE/DCE interface connector and contact number assignments "(in English).

This standard replaces GB/T 9952-1988 "Data communication - 15 pin DTE/DCE interface connector and pin assignments." this standard and GB/T 9952-1988 compared to the main changes are as follows.

--- The standard add technical details about connectors and associated components defined;

--- This standard gives the connector connection method;

--- This standard increases the informative Appendix A.

This standard Annex A, Annex B, Annex C is informative appendix.

This standard by the National Information Technology Standardization Technical Committee and centralized.

This standard was drafted. China Electronics Standardization Institute, Beijing Electronics Co. voice.

1 Scope

This standard specifies the data terminal equipment (DTE) and data circuit terminating 15-pin connector interface between equipment (DCE) and Contact number assignments, this interface is suitable for compliance with GB/T 11594, GB/T 7618 and GB/T 7619 device.

This standard provides an additional dimension of the connector housing, and recommended locking device (locking member) and the connector shield means.
