Is there any relation between Protocol used like ATM and physical cables like Fiber Optic?
Answer Hello, Yes, there is a relation between the L2 protocol used and the L1 cable used to connect that device to the network. This is because the L2 protocol determines how the electrical signalling will occur at the physical layer, which actually is how the data is transmitted, and this has to be supported by the physical medium, that is the cable, and hence different types of cables are required when using different type of protocols. You may go through the below links to get more information on this – http://en.wikipedia.org/wiki/OSI_model (physical layer section) http://www.support.nsgdata.com/RouterDocs/lib56/user_guides/gt_100_series/cablsp…
