Abstract :
The repeater described in this paper is a part of the 45BN carrier telephone system. This system transmits and receives 24 voice channels over two pairs in a nonloaded exchange or toll cable. It is a member of a family of miniaturized carrier systems using many interchangeable subassemblies.1,2,3 The complete family of type 45 carrier equipment provides carrier transmission over open-wire cable and radio circuits.
