INTERFACE ARRANGEMENT BETWEEN NETWORK NODE AND RADIO ACCESS UNIT

摘要

The present invention relates to an interface arrangement configured to convert signals transported on a coaxial cable between a network node and a radio access unit. The interface arrangement comprises overvoltage protection arranged to interface with the coaxial cable. Further, the interface arrangement comprises an Ethernet-over-coax adapter arranged to convert between Ethernet signals of a first format transported on the coaxial cable connected to the network node via a first interface and Ethernet signals of a second format transported over a second interface connected to the radio access unit. Moreover, the interface arrangement comprises powering means arranged to provide DC voltage to the radio access unit via the second interface.
