ABSTRACT:
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.
