OSI model
Hi You removed my commit, can you please expand on it? Is it only the "Layer 0: " you don't like? {{Quote|text=

Layer 0: Physical media
ISO/IEC 7498-1, refence to physical media as:
 * "provides the means for transfer of information between open systems" (4.2.8)
 * Is part of the four elements that is basic for the OSI-model (5.1.3).
 * The lowest layer abstracts the physical media that connect them (5.2.2.4)
 * Real subnetwork, is a all the equipment and physical media, which forms a autonomous system (7.5.1.1).

This includes: }} EidenNor (talk) 06:15, 4 April 2024 (UTC)
 * Cabling infrastructure
 * Wavelength-division multiplexing
 * Radio


 * Whatever Belden's marketing writes, there is no layer 0 in OSI. The physical media are all layer 1, the physical layer,, see ISO 7498 clause 7.7.
 * And we're not discussing this here but in Talk:OSI model. --Zac67 (talk) 06:28, 4 April 2024 (UTC)
