ABSTRACT:
A modular distribution frame assembly for carrying telephone line terminal and protection blocks in a substantially complete factory-prewired condition. The modular distribution frame has a base for securing to a floor support and a telescopic upper end for securing to an overhead support. The distribution frame assembly has a main vertical open column for receiving the plurality of jumper wires which are used to interconnect incoming subscriber or trunk lines with central office distribution lines. Incoming lines can be introduced into a secondary vertical open column located next to the main open (jumper) column for connection either directly to the appropriate protection or line terminal blocks or to a multiposition connector which has its mating half mounted to and electrically connected to the appropriate protector or line terminal blocks. Central office distribution lines are also connected either directly to the appropriate protector or line terminal blocks or to a multi-position connector which has its mating half mounted to and electrically connected to the appropriate protector or line terminal blocks. Multi-conductor cables with connectors on each end or cables wired directly to the blocks with connectors at one end only can be provided for rapid interconnection between the protector blocks and the appropriate line terminal blocks, or cables wired directly between appropriate blocks. A plurality of prewired modular distribution frames are secured next to one another in a row or circular pattern and interconnecting jumper cables are connected between selected groups of the frames to minimize the length of jumper wire needed to connect an incoming protected wire pair with a central office wire pair.
