5, but they are usually sited at convenient town centres for example. As a cellular radio network grows, and the number of subscribers increases, the mobile switching centres have to begin handling a very large amount of traffic. g. 1000 x 1000 crosspoints, that is 1000 lines connecting another 1000 lines, must expand to a full capacity fixed telephone exchange. • Again, as with the normal public switched telephone network (PSTN), full intermeshing of MSCs becomes very costly and therefore a second tier of overlay transit switching centres (TSC) is now common in cellular networks, giving a hierarchical network as associated with the fixed telephone network.
