Abstract (en)
[origin: WO8909414A1] An apparatus and method for the efficient generation of a wiring map of the connectivity between two sets of terminals (1, 2) at different locations which have established communication links (3) between respective terminals at the two locations. A signal at a first location (1) uniquely identifies each of the terminals, by code, frequency, sequence of connection or the like, and is transmitted to a respective terminal at the second location (2) via a respective communication link (3). The terminals at the second location (2) are sampled and the presence of the transmitted signal correlated to the identity of the first terminal (1). The correlation may be direct, as by unique terminal identifier, or by a comparison of databases stored by computers.
