ABSTRACT:
For each of a plurality of signal processors accommodating respective shares of signalling links to be controlled by a signalling point, a congestion-condition level is determined by comparing an overload condition of a central controller and the number of processed signals with their respective threshold values. Any signalling link, whose priority is lower than the priority corresponding to the determined congestion-condition level, is inhibited for use, and a signalling link accommodated in another signal processor is substituted for the inhibited signalling link. In determining the congestion-condition level, a decision is made at predetermined intervals of time as to whether the condition is a congested condition or a congestion cleared condition; if it is a congested condition, the congestion-condition level is raised, and if it is a congestion cleared condition, the congestion-condition level is lowered.
