The standard proposed by the Ministry of Industry and Information Technology of the People's Republic of China. The standard by the China Communications Standards Association. This standard was drafted. the Ministry of Industry and Information Technology and Telecommunications Research Institute, Shanghai Bell Co., Ltd. The main drafters of this standard. Disaster - Beijing, Chen Cheng. This standard was first released in December 1989, revised for the first time in 1999, this is the second revision.IntroductionMany countries have established to provide packet-switched data transmission services for public data network, which is necessary to induce the public to develop some criteria Telephone network, circuit-switched public data networks and leased circuits accessing a packet switched public data networks. ITU-T Whereas. a) ITU-TX.1 and ITU-TX.2 provides public data networks and user service class user facilities, ITU-TX.96 provisions Call signal, ITU-TX.29 specifies the packet assembly and disassembly (PAD) facility and a packet mode DTE or another PAD of Communication protocol between, ITU-TX.28 provides start-stop mode DTE access the PAD DTE/DCE interface; b) ITU-TX.92 provides packet-switched data transmission services on the logical link control, especially considering ITU-TX.92 The case contains a PAD; c) the urgent requirements of the PSTN, public switched data network or leased circuits using the start-stop mode DTE and can use the packet Switched data services interworking between the virtual call facility of the packet mode DTE or another start-stop mode DTE; d) transmission and reception will be in the form of characters start-stop mode DTE operation or "off" signal network control information and user information; e) DTE grouped by mode of operation will comply with the form of packets sent and received ITU-TX.25 network control signal and user information; f) Although not mandatory packet mode DTE using the control procedures for PAD functions, but some may want to control the packet mode DTE Make certain functions of PAD. Unanimously recommended. a) for functional and operational characteristics of start-stop mode DTE, the PAD executed, will be available in the basic functions of the l Chapter "PAD and user Description of selected functions "within the description; PAD operation b) for the start-stop DTE should depend on the possible values of PAD parameters known internal variables, these PAD parameters In Chapter 2, "PAD parameter characteristics" Description; PAD parameter c) for start-stop mode DTE and the possible values for these parameters should be in Chapter 3, "PAD parameters and possible values at a glance Table "Those parameters and values listed; d) future research will expand 1, 2 and PAD performance described in Chapter 3, with the start-stop mode DTE is not the type to make it non-packet DTE interworking. Public data network packet assembly and disassembly facility (PAD) 1 PAD basic functions and user-selectable functions described Features and operating characteristics of the 1.1 PAD PAD performs many functions and have many operational characteristics. Some of these features make start-stop mode DTE and (or) the packet mode DTE (or Distal PAD) PAD can select the configuration so that the PAD operation to fit the characteristics of the start-stop mode DTE and may be put to use. 1.2 PAD operation PAD operation depends on the value of PAD parameter is called a set of internal variables, each of the start-stop mode DTE set parameters in this group is the only Li, the current value of each PAD parameter specifies the operating characteristics of their related functions. 1.3 PAD function 1.3.1 Basic Functions --- Each character grouping; --- User data field split the packet; --- Establish a virtual call handling, clear, reset and interrupt procedures; --- Generating traffic signals; --- When the conditions are suitable, such as packet full or idle timer expires, there is a packet forwarding mechanism; --- Have a mechanism to send data to the start-stop mode DTE characters, including play, stop and parity symbols; --- Handling mechanism "off" signal from the start-stop mode DTE; --- Edit PAD command signal; --- Set and read PAD parameter mechanisms existing values. 1.3.2 Optional Features --- Selection criteria outline mechanisms; --- Automatic detection of the data rate, code, parity bit and operational characteristics; --- Between the start-stop mode DTE and the remote DTE to another DTE mechanism virtual call request. Users can choose to provide 1.4 PAD function Many packet-switched data network facilities, or by prior agreement, or you can specify for each call, ITU-TX.2 for the first 20 to 22 Start-stop mode DTE user service category describes use. In addition, it may also be agreed in advance with the following features. --- Select the initial outline; --- Modem type PAD use, speed, and parity of the code; Other operating characteristics --- DTE's. This standard provides a number of relevant parameters provides the following functions. Practice management --- start-stop mode DTE and a PAD between; --- Management packet assembly and disassembly; --- Some additional features and operating characteristics of the start-stop mode DTE's; --- Some additional features and videotex application-related. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 11591-2011_English be delivered?Answer: Upon your order, we will start to translate GB/T 11591-2011_English as soon as possible, and keep you informed of the progress.
