Miles of wire are usedin the distributing frame in his largecentral office to connect the cablepairs and the central office equip-ment together. Additional sub-scribers, number changes, subscribermoves, and cable and equipment re-arrangements require these wires onthe distributing frame to be connectedto different terminals. Often the oldwire is too short to reach and hasto be replaced with a longer piece.These short lengths are carefullysaved and used over again, either inthe same office or in smaller neigh-boring offices.
