When provided by different vendors need to communicate between devices and the underlying system architecture can not be placed in its own application layer interfaces should be used in this section. Information structure according to the OSI layered protocol proposes to provide choice and use of low-level transmission media and protocol flexibility. Common application layer protocol provides for a list of all supported devices in this section provide a minimal subset of, and defines may provide extended range. Protocol design allows it to be defined here is extended outside the scope of the information, so you can provide more functionality and manufacturer-specific extensions. This section applies to the transmission of alarm messages and sent to/from intrusion, fire, access control and social alarm systems and other information transmission, and sent to/from other similar information transmission systems. | GB/T 21564.2-2008: Message formats and protocols for serial data interfaces in alarm transmission systems -- Part 2: Common application layer protocol

Foreword
GB/T 21564 "for serial data interfaces in alarm transmission systems of information formats and protocols" is divided into five parts.
--- Part 1. General
--- Part 2. Common application layer protocol
--- Part 3. Common data link layer protocol
--- Part 4. Public transport layer protocol
--- Part 5. Data Interface
This section GB/T 21564 Part 2.
The partial modification adopts the International Electrotechnical Commission IEC 60839-7-2.2001 (in English).
For ease of use, this section made the following changes.
--- Appendix date and time have content related to "year" are deleted, the data block length calculated from the beginning of May;
--- Appendix "A.5 name/address" chapter, the data length of the "name" to "up to 8 characters + CR.", "Address 2" is replaced by "the most
Length 48 characters + CR. ";
--- Appendix "A.19" chapter, add annotations, using more easy to understand;
--- Remove the original IEC foreword, an increase of introduction.
This section of the Appendix A, Appendix B are normative appendix.

Introduction
Serial data communication is the main variety of communication model manifestations.
This section is based on the earlier point RS-232 and RS-485 communication model multipoint serial communication bus model developed
of. Therefore, broadband applications and wireless transmission is currently being widely used not been detailed presentation, only in some links and comments given
prompt.
Although the communication rate model This section gives slower, but the data transfer control theory and modern types of broadband applications and wireless applications
Use is the same, so this part has a very good guide for alarm product designers, planners user alarm systems and alarm systems, etc.
The role and significance of the demonstration.
By the ITU-TV. 24 and ITU-TV. 28 provisions of the common interface, it is currently familiar EIA-RS232 interface, which is suitable
For synchronous and asynchronous serial binary data exchange system, the interconnection between data terminal equipment serial interface protocol is an unbalanced
Transmission, and to/from the transmission of information to other similar systems.

5 Application Layer Functionality
In alarm transmission systems, the application layer is responsible for the basic information required to transfer data to be formatted. It must also be remote from
Respond with basic information layer.
The following functions, protocols, structure and format to meet the basic requirements of the serial data interface.
6 Basic data block
Alarms and other information to be transferred should be formatted into basic blocks. They consist of two or more bytes composed of 8 bits.
