Abstract :
Cellular networks have always relied on connections between each basestation and a mobile telephone exchange or switching centre (MtX/MsC) to ´backhaul´ phonecalls and mobile data to the rest of the network. Backhaul has for years been taken for granted by all but a relatively small group of technicians and engineers who manage, maintain, and develop the time-divisionmultiplexing (TDM) systems that provide this vital connectivity.
