GB/T 11599-2009Use on public data networks of data terminal equipment (DTE) which is designed for interfacing to synchronous V-series MODEMs (English PDF)

Foreword

This standard is equivalent to ITU-TX. 21bis. 1988 "Data Terminal Equipment (DTE) with interface to synchronous V-series modems Public data online usage "(in English).

This standard replaces GB/T 11599-1989 "Data terminal equipment (DTE) that interfaces with synchronous V-series modems in public numbers According to online usage ".

This standard and GB/T 11599-1989 compared to the main changes are as follows.

- Added Chapter 1, "Scope", Chapter 2, "Normative References", Chapter 3, "Abbreviations", the original chapter in sequence;

--- will be cited standard "GB 11589-1989" revised to "GB/T 11589", the reference standard "GB 11593-1989" revised to "GB/T 11593", the reference standard "GB 11595-1989" revised to "GB/T 11595";

--- increase 5.1 overview;

- 5.2.1.1 "However, in the case of half-duplex facilities, the detection of line signals should be replaced by some other control mechanism." in the case of half-duplex facilities, the detection of line signals should be replaced by some other control mechanism. "

--- In the 6.2.1.1.3DCE clear indication/DTE clear confirmation, "After the DCE clear indication is issued on circuit 107 Within 100 ms, the DTE turns the circuit 108/1 or 108/2 into an off state to give the DTE clear acknowledgment signal "modified to" the DTE turns the circuit 108/1 or 108/2 into an off state within 500 ms after the DCE clear instruction is issued on the circuit 107 Give DTE clear confirmation signal ";

--- 6.3.1 "DTE Controllable Not Ready" to "Controlled DTE Not Ready";

--- 6.3.2 "DTE controllable not ready" to "controlled DTE not ready";

- In the 7.3.2 local test loop --- Category 3 loop, "in the country test rules allow the occasion, the loop 3 can be from A state is established. "Revised to" Loop 3 can be established from any of the conditions that meet the relevant domestic test standards. " - In the 7.3.2 local test ring --- type 3 loop, the "DCE test loop on the specific device selected by the country." "The specific equipment on the test loop of the DCE can be harmonized according to the actual situation of the relevant domestic testing standards.

--- In the 7.3.3 network test loop --- the second type of loop, "in the national test principle allows the occasion, DTE can Under the use of loop 2. "modified to" in line with the relevant domestic test standards under the conditions, DTE can be used as follows loop 2. ".

--- In the 7.3.3 network test loop --- the second type of loop, the "DCE test loop of the exact device is the national option Purpose. "Modified to" DCE test loop within the exact device by the relevant domestic test standards according to the actual situation uniform specification. " - In the 7.3.3 network test loop - type 2 loop, the method used for loop control and automatic control is defined by National choice. "Modified to" loop control and the use of automatic control methods used by the relevant domestic testing standards based on the real Uniform norms of the situation. " Appendix A of this standard is a normative appendix.
