Abstract: A method is provided for monitoring the progress of a software upgrade or retrofit on a telecommunications switch (110). A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is received by a server (102). Predetermined messages are detected in the report stream, including messages indicating entry into a stage of the retrofit, exit from a stage of the retrofit, a failure of a stage of the retrofit, alarms and errors. The time spent in a stage of the retrofit is determined and compared against an expected time (206, 210, 212). A visual portion (300, 400) of a user interface on a client (104) is updated to reflect entry and exit from a stage of the retrofit, and whether the time spent in a stage exceeds an expected time. The user interface reflects occurrences of alarms and errors visually and in some cases audibly.

Abstract: A method is provided for determining whether the immediate state of a telecommunications switch (110) is adequate for a software upgrade or retrofit. A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is received (200) by a server (102). Predetermined messages are detected in the report stream, including messages indicating hardware errors, alarms and other errors (202). The predetermined messages have a numerical value associated therewith (204). The numerical value reflects a probability of failure of a retrofit if the message is detected. As the predetermined messages are detected, their numerical values are accumulated into an accumulated value (206). If the accumulated value exceeds a threshold, the switch is not fit for the retrofit (210, 211). The time spent receiving the report stream is determined and compared against an expected time (216).

Abstract: A method is provided for determining whether the state of a telecommunications switch (110) is adequate for a software upgrade or retrofit. A report stream of text messages relating to the state of, and events occurring on, the telecommunications switch is stored (200) by a server (102). Predetermined messages are detected in the report stream, including messages indicating hardware errors, alarms and other errors (202). The predetermined messages have a numerical value associated therewith (204). The numerical value reflects a probability of failure of a retrofit if the message is detected. As the predetermined messages are detected, their numerical values are accumulated into an accumulated value (206). The time period the report stream covers is determined and compared against an expected time (216). If the time period covered by the report stream does not exceed an expected time, then a determination regarding suitability for upgrade may not be reliable (222).
