ROUTING CODE Combination of n digits, which can characterize a switch, a re-gion, a numbering area or a country, to which the analysis in theanalysis tables relates. A routing code is said to be forwardedif there is a routing list for it.

Other terms are:

super routing code: sequence of first n digits where n < n,

sub-routing code: sequence of first n" digits where n"> n.

ROW Suite of racks.
