Self Test Features
The Agent Greeting Card runs various diagnostics to detect hardware faults
and ensure correct operation. The test coverage breaks down into the
following categories:
• 8051 co-processor power up self tests
• BIOS diagnostics
• Base code self tests
Progress information of self tests is available through the serial port on the
Agent Greeting Card.
Factory Test Features
Factory test features include the HEX Display, Status LED and Reset Switch.
HEX Display
The Agent Greeting base card includes a HEX LED display to provide status
information during maintenance operations. During power-up and diagnostic
tests, this display provides a visual progress indication, and information on
the first failure detected. The HEX LED display codes are indicated in
Table 2, “: HEX Display codes during bootup,” on page 20.
During normal operation the display cycles through the number of enabled
M2616 (Aries) ports, the number of booted DSP ports, the number of
channels authorised by a keycode, and the total channel capacity of the card.
For example the HEX display could contain:
