ABSTRACT:
A method of initializing a set of node addresses by using an apparatus having a CPU, a ROM and a NVSRAM for use in an electronic switching system comprises the steps of: (a) checking if there is a request to change the set of node addresses; (b) updating the NVSRAM with a new set of node addresses, and then going to step (f) if there is the request at the step (a); (c) checking if a flag in the NVSRAM is set or not when there is no request at the step (a); (d) going to the step (f) if the flag in the NVSRAM is determined to be set at the step (c); (e) copying the node addresses stored in the ROM to the NVSRAM if the flag in the NVSRAM is determined not to be set at the step (c); and (f) copying the set of node addresses stored in the NVSRAM onto the corresponding nodes.
