For example, an IEEE 802.3at compliant PD and/or IEEE 802.3af compliant PD will interoperate with an IEEE 802.3bt compliant PSE.company believes it is advantageous to design with IEEE 802.3bt compliant devices moving forward for 4-Pair and 2-Pair operation due to the benefits that the .bt standard offers over previous standards such as the new MPS signature, autoclass, power demotion, and more.
