  • Tracing with keys and locks
    Patent number: 5594904
    Abstract: A method and apparatus for detecting events occurring in a telecommunications network is disclosed which comprises stored program control (SPC) exchanges, each SPC exchange comprising a switch and processors for executing software programs to control the switch. Code sequences, or daemons, are implanted in selected portions of the software programs, each code sequence including a conditional statement responsive to certain events and at least one activity resulting from the detection of a certain event satisfying the conditional statement. A lock value is assigned to each of the code sequences, each lock value uniquely identifying the corresponding code sequences and being operable to activate the processor for executing the code sequence. A key value is compared to each lock value for selectively activating the processor to execute the code sequence when the key value equals the lock value.
    Type: Grant
