Annotation

This Technical Report:

• targets the support of applications that provide remote power over balanced cabling to terminal equipment;

• covers the transmission and electrical parameters needed to support remote power over balanced cabling;

• covers various installation scenarios and how these may impact the capability of balanced cabling to support remote powering;

• specifies design and configuration of cabling as specified in International Standards ISO/IEC 11801, ISO/IEC 15018, ISO/IEC 24702 and ISO/IEC 24764;

• provides requirements and guidelines that will enable the support of a wide variety of extra low voltage (ELV) limited power source (LPS) applications using remote power supplied over balanced cabling.

Requirements and guidelines are provided with respect to

• cabling selection and performance (Clause 5),

• installation conditions (Clause 6),

• transmission requirements (Clause 7),

• power delivery (Clause 8),

• connecting hardware (Clause 9),

• mitigation considerations (Annex A).
