Example – Modulo-2 Arithmetic Method Given D = 1 0 1 0 0 0 1 1 0 1 P = 1 1 0 1 0 1 Find the FCS field Solution: First we note that: The size of the data block D is k = 10 bits The size of P is (n – k + 1) = 6 bits Hence the FCS length is n – k = 5 Total size of the frame T is n = 15 bits Example – Modulo-2 Arith. Method Solution (cont...
