Abstract
Abstract An interface or connector for providing distribution of telephone feeder cable pairs includes first, second and third fields of connectors. The connectors in the first field can be interconnected with any connector in the third field or with an associated connector in the second field but not with both simultaneously. The connectors in the first, second and third fields are respectively connected to feeder-in cable pairs, feeder-out cable pairs and distribution pairs. Accordingly, a pair in the feeder-in cable can be made available at a plurality of interfaces but can only be used at one interface at any given time.
