초록 ▼

A remote measurement unit for testing and conditioning one or more telephone lines includes multiple electronically erasable flash memory banks, which contain respective versions of the operating system employed by the test unit\s micro-controller. An operating system modification routine employed by the host processor of a remote site allows the functionality of the remote test unit to be selectively modified by electronically installing an upgraded or downgraded version of the operating system, or by electronically selectively activating or deactivating one or more operational features of the currently active operating system. A reset routine ensures that the operating system modification mechanism will only boot up the ‘correct’one of the two quasi-redundant systems available to the RMU\s microcontroller after a system modification has been performed. In addition, the temporary insertion of a no-op code field just prior to the beginning of the program prevents the RMU\s processor from accidentally booting up a modified system until the system has been verified as operational.

대표청구항 ▼

For use with a communication system having one or more remote sites at which respective programmable test devices are located, a respective programmable test device employing an operating system for monitoring and testing network lines and subscriber termination equipment coupled thereto, said communication system further including at least one data terminal unit which has the capability of accessing said programmable test device and causing a modification of said operating system, said respective programmable test device containing first and second memory systems, which contain respective first and second versions of said operating system, a method of controlling which of said first and second versions of said operating system is executed by said programmable test device when said programmable test device is placed in operation, comprising the steps of: (a) processing the contents of a prescribed portion of said first and second memory systems to verify operational validity thereof; and (b) causing one of said first and second versions of said operating system contained in said first and second memory systems, for which step (a) has verified operational validity, which has the latest revision level and is not in a downgraded status, to be executed by said programmable test device.
