Circuitsare laid out in such a way as to avoidcenters of testing and rearrangement ac-tivity. And adequate protective devicesare installed to insure against the effectsof very high voltage or currents arounda power station. Next, we must take advantage of theextensive multiple restoration capabili-ties in the telephone network. Dual cir-cuit routings, say with one route on cablefmd another on radio, can be recom-mended to the customer at only modestextra cost. Planned reroutes can be setup for individual circuits. And broad-band restoration plans, whereby wholemicrowave channels can be rerouted inminutes, will often be applicable.
