ISO/IEC 13239:2002 Information technology
Telecommunications and information exchange between systems — High-level data link control (HDLC) procedures
HDLC is a layer 2 data link protocol that is commonly used in point-to-point and point-to-multipoint applications. It was originally developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
What is ISO 13239:2002?
ISO 13239:2002 is an international standard that defines the procedures for high-level data link control (HDLC). HDLC is a type of data link layer protocol that is commonly used in point-to-point and multipoint communication systems.
The standard was first published in 2002 and was last updated in 2012. It is maintained by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
ISO 13239:2002 defines the following aspects of HDLC:
- Frame structure
- Bit ordering
- Control field format
- Address field format
- Information field format
- CRC calculation
- Error detection and correction
- Data compression
- Link management
What are the requirements of ISO 13239:2002
In order to be compliant with ISO 13239:2002, a HDLC implementation must support the following features:
- Support for both point-to-point and multipoint configurations
- Support for full-duplex and half-duplex operation
- Support for asynchronous and synchronous transmission
- Support for unbalanced and balanced mode transmission
- Support for transparent and non-transparent operation
- Ability to operate at any data rate from 1 kbit/s to 4 Mbit/s
In addition, the HDLC implementation must also be able to provide the following services:
- Connectionless data service
- Sequenced data service
- Priority data service
What are the benefits of ISO 13239:2002?
The benefits of ISO 13239:2002 are many and varied. Perhaps the most important benefit is that it provides a standard for high-level data link control (HDLC) procedures. This can be extremely important for businesses that need to exchange information between systems, as it helps to ensure compatibility and interoperability.
Another major benefit of ISO 13239:2002 is that it helps to improve efficiency and reduce costs. By providing a standardised HDLC procedure, businesses can avoid the need for customised solutions that may be expensive and time-consuming to develop. In addition, the use of a standardised HDLC procedure can help to speed up communication and reduce errors.
Overall, ISO 13239:2002 can provide many benefits for businesses that need to exchange information between systems. By helping to ensure compatibility and reducing costs, it can make exchanging information simpler, faster and more accurate.
It facilitates the exchange of information between different systems and software used in construction projects.
