25/**
26 * <p>
27 * The network appearance is a number assigned by the signaling gateway and the
28 * ASP that, when used along with the signaling point code, uniquely identifies
29 * an SS7 node in the SS7 domain.
30 * </p>
31 * <p>
32 * This is used when a signaling gateway is connected to multiple networks, and
33 * those networks are in different countries, for example. When this occurs, the
34 * SS7 point codes that are assigned could be duplicated. For example, if the
35 * node has an appearance in France and also in the United Kingdom, the point
36 * code advertised in those two networks could be duplicated because national
37 * point codes are of local significance only.
