Rs-232 Terminal - 3Com V7111 - VCX 4 Channels Analog FXO Media Gateway User Manual

Detailed self-test mode is invoked when initialization of the Gateway is completed and if the
configuration parameter EnableDiagnostics is set to 1 (this parameter can be configured
through the INI file). In this mode, the Gateway tests all the hardware components (such as
memory and DSP), outputs the status of the test results, and ends the test. To continue
operational running, reset the Gateway again but this time configure the EnableDiagnostics
parameter to 0.
