This standard is one of a group of standards formulated to facilitate the interconnection of information systems, and it is related to other standards in a group of standards defined by the Open System Interconnection Reference Model (GB 9387-88). The reference model subdivides the field of interconnect standardization into a series of specification layers of manageable size.

These systems can - come from different manufacturers; - adopt different management methods; - have different levels of Complexity;
