摘要 |
The invention discloses an arrangement ( 100 ) in a base station in a cellular mobile telephony system, comprising a first plurality ( 120 - 160 ) of Printed Circuit Boards (PCB:s) and a second plurality of switches ( 110,190 ). Each of the PCB:s ( 120 - 160 ) in said first plurality is connected to each of the switches ( 110,190 ) in said second plurality. Each of the switches ( 110,190 ) is equipped with means for communicating with and polling each of the PCB:s ( 120 - 160 ) at predetermined intervals, said polling being with regard to the status of the PCB. The switches are equipped with means for distributing status information to the individual PCB:s as an outcome of said polling, and the PCB:s are equipped with means for communicating with each other via one, several, or all of the switches, and said communicating means in the PCB:s are arranged to choose routes of communication based on said status information received from the switches.
