使用数据终端设备(DTE)和数据电路终接设备(DCE)测试环路的公用数据网的维护测试原则

PRINCIPLES OF MAINTENANCE TESTING FOR PUBLIC DATA NETWORKS USING DATA TERMINAL EQUIPMENT (DTE) AND DATA CIRCUIT-TERMINATING EQUIPMENT (DCE) TEST LOOPS

ITU-T X.150 SPANISH-1988 发布历史

This Recommendation specifies the principles of maintenance testing for public data networks using the DTE/DCE test loops. The definition of the loops, the principles for the control of the loops and the principles for the indications to be presented when the loops are activated are described herein for general application with all DTE/DCE interfaces. Specific details concerning the implementation of these principles are contained in the individual DTE/DCE interface Recommendations. The maintenance philosophy, definitions and general principles are applicable to interface Recommendations, such as X.20, X.20 bis, X.21, X.21 bis, and X.22.
