TIA TSB-5019 PDF

The scope of this telecommunications systems bulletin is to identify, analyze, and recommend use cases (e.g. switch fabric architectures, End-of Row, and Top-of-Rack) for high performance structured cabling (HPSC) application environments utilizing next generation BASE-T standards with data rates above 10GBASE-T such as 25GBASE-T or 40GBASE-T. The use cases can be incorporated in data center or premise designs to ensure that the designs can accommodate future cabling and application standards.

The premise designs may be test laboratories or equipment rooms that have requirements for high bandwidth similar to data centers. HPSC is generic but the use cases are specific to a variety of different environments or situations.
