  • Debugging and cosimulation method for wide band switch firmware
    Patent number: 6272454
    Abstract: An RS232C driver inside target firmware controls an RS232C interface. An OS debugger steals an input to and an output from another function block that is the actual target firmware, and exchanges that input and output with the RS232C driver 1005. This configuration makes it possible to easily connect a device that executes the target firmware to, for example, a personal computer, using a general purpose RS232C interface, and makes it possible to easily obtain debugging operation using the PC side debugger.

  • ISDN switching system having testing facilities
    Patent number: 5442621
    Abstract: An ISDN switching system having facilities for testing an ISDN signal composed of B-channels and D-channels at least. The testing facilities can achieve a B-channel test and D-channel test selectively with simple construction by employing a converting unit in the system. The converting unit enables creation of a connection path between a test equipment and an object to be tested through an ISDN exchange and thus the ISDN signals for the test can be treated as usual ISDN signals. Thereby, the test equipment and the object can freely be connected to each other.
