First Claim
1.

- a) monitor means including first processor means coupled with said links to provide real time monitoring of the link signals and provide first output signals indicative of predetermined conditions therein;
b) second processor means receiving and analyzing said first output signals and providing second output signals responsive to said analysis;
c) third processor means receiving said second output signals from the second processor means and analyzing said signals, said third processor means being coupled with a mated pair of said STPs so as to provide control signals to control the monitor means coupled to the links of said pair of STPs, said third processor means generating third output signals including alarm and corrective action signals responsive to conditions determined from the signals from said second processor means;
d) fourth processor means receiving and analyzing said third output signals and providing fourth output signals responsive to the results of said analysis of said third output signals; and
e) input terminal means connected to at least one of said processing means for manually controlling said monitor means.

Abstract
An SS7 Network Preventative Maintenance System for detecting potential SS7 and switched network troubles, automatically analyzing the troubles, providing alarm and corrective action to avoid major network events. Real time monitors on SS7 links at the STP provide information on exceeded link load, exceeded Message Signaling Unit (MSU) frequency and network management status/error conditions in a Stage 1 Process. The Stage 1 Process provides alarm information to a Stage 2 Process which controls all Stage 1 associated monitors for an STP pair. Stage 2 reacts to Stage 1 signals to generate alarm and corrective action information which is passed on to a Stage 3 Process. The Stage 3 Process controls all Stage 2 Processes in the operating company. Stage 3 reacts to Stage 2 output to detect potential or real accompanying network trouble and generates alarm and corrective action information and displays in response thereto. Stage 3 also alerts a Stage 4 process which is connected to all Stage 3 Processes in a region. Stage 4 analyzes data from Stage 3 to determine if similar trouble could happen in another network where upon Stage 4 informs affected Stage 3 Processes regarding the same. Corrective action/trouble verification information is generated and passed on. An Interface to the network'"'"'s surveillant system is provided.
