logical Hear it!

logical definition - telecom
  1. Based on facts, rational thought, and clear reasoning.
  2. Referring to something that does not exist, but has the appearance or effect of physical presence. In the context of telecommunications, a logical circuit, for example, does not have a physical presence in the sense that it is not tangible. Rather, it is defined as some amount of bandwidth provided over a physical, i.e., tangible, circuit that may support many logical circuits. Similarly, a channel may be in the form of regular time slots provided over a digital circuit.The time slots are brief moments in time during which electromagnetic signals convey bits of information associated with a given data transfer. Such a channel is purely logical, with no material presence and no physical presence except to the extent that the electromagnetic energy is the stuff of the science of physics. See also channel, circuit, digital, physical, physics, signal, and time slot.
