Local area network : defined

There is an ongoing debate about extending CISPR 22 to include mandatory full testing on telecom ports. Telecommunication ports are defined as those which are intended to be connected to telecommunications networks (e.g. public-switched telecommunications networks, integrated services digital networks), local-area networks (e.g. Ethernet, Token Ring), and similar networks. There is also a possibility that other product standards will... 

LAN Local Area Network. A network that coimects computers in a small, defined area, such as the offices in a single wing or a group of buildings. 

The number and types of pieces of analytical equipment to be integrated into the LIMS (e.g., gas chromatographs, sampling systems, mass spectrometers, etc.). There will also be a requirement to define the means of communication with these pieces of equipment this communication link may be t5q)ically via RS232 or a local area network (LAN). 

Both the physical and logical attributes of the network should be defined in technical specifications. Textual descriptions supported by diagrams, addressing OSI layers 1 and 2, should be produced, defining all networks at both local and wide area levels. Documentation should specify all physical components. References should be made to the industry-wide standards that were followed.
