Abstract
Abstract A modular, high density cross-connect frame specifically adapted for central office application and forming a centralized distributing frame intended for patch and cross-connect circuits for digital equipment. The frame is dual sided, with the patching and testing administration entirely on one side confined to an area readily manually and visually accessible to service personnel, with cross-connect administration confined to the opposite side.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
262 words
An improved telephone frame for cross connecting digital switching systems to provide central cross connect points comprising: a vertically oriented base frame element including first and second sides for the mounting of connecting elements; said first side defining an upper transversely extending area, said area having a plurality of first connector blocks mounted thereon in juxtaposed relation, and vertical and horizontal trough-forming means adjacent said connector blocks for receiving outside plant cables connected with said first connector blocks; said first side defining a lower transversely extending area disposed beneath said upper area, said lower area having a second plurality of connector blocks thereon, and vertical and horizontal trough-forming means for receiving inside plant cables connected with said second plurality of connector blocks; said second side of said base frame element defining a third upper transversely extending area corresponding to and oppositely disposed to said first transversely extending area, and having a third plurality of connector blocks thereon in juxtaposed relation, and vertical and horizontal trough-forming means for receiving outside plant cables connected to said third plurality of connector blocks; said second side defining a fourth lower transversely extending area opposite said second lower transversely extending area of said first side of said base frame element, and having a plurality of connector blocks forming jackfields, the individual jacks of which are connected to a connector block communicating with either outside plant or inside plant cables; whereby upon installation, said frame may be completely administered from said second side utilizing access to said jackfields at vertical levels corresponding to said fourth transversely extending area.

Claim 3
Dependent Claim
32 words
An improved telephone frame in accordance with claim 1, further characterized in said fourth transversely extending area extends to a vertical height of approximately three-quarters of the total height of said frame.
