ATIS T1.TRQ.5-2001

This Technical Requirements document provides maximum dc steady-state voltage, current, and power limits to be observed when powering transport systems over conventional network telecommunications twisted-pair conductors. The technical requirements contained herein are based on industry-recognized safety standards, address both the network and customer premises environments, and are independent of the transport system technology employed. Signaling levels and transients are not covered, but should be considered when evaluating a transport system for conformance to these requirements if they will impact voltage, current, or power levels.
