Abstract
Abstract An improved telephone modular distributing frame is disclosed. The frame is particularly adapted for use with relatively large connector blocks in conjunction with relatively smaller protector blocks with provision made for maximum space utilization, ease of installation, and ready availability of the protector blocks after installation. The frame is double sided, and is characterized in the spacing of the connector blocks upon a greater area on one side of the frame, and a relatively lesser centrally located area on the opposite side of the frame where the protector blocks are located.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
167 words
In a two-sided telephone modular distributing frame using pre-wired block modules, each including a connector block mounted on one side of said frame and an interconnected protector block having individual protector modules thereon mounted on a second side of said frame, said connector blocks being substantially larger in overall configuration than said protector blocks, the improvement comprising: said first side of said frame having a vertically spaced plurality of horizontally oriented tubular members defining interstices accommodating said protector blocks, said second side of said frame having a plurality of vertically spaced horizontally oriented trough members defining interstices accommodating said connector blocks; said connector blocks occupying a given area on said second side of said frame, said protector blocks occupying a second area on said first side of said frame substantially smaller than that of said given area, said second area being positioned to occupy vertically a generally medial portion of said given area, whereby the protector modules of said protector blocks are readily available to service personnel.
