Voice Gateway Media Card self-tests

During power-up, the Voice Gateway Media Card performs diagnostic tests
to ensure correct operation. The faceplate RS-232 port on the Voice Gateway
Media Card can be used to monitor the progress of these tests. When the
processor responds correctly, the controller switches its serial port to provide
Card LAN communication and connects the processor with the external
RS-232 port.

Troubleshoot a software load failure

Symptoms
OTM cannot establish connection with the Voice Gateway Media Card. The
faceplate LCD display reads “BIOS.”
Problem
The Voice Gateway Media Card has booted the BIOS load.
Diagnosis
In the event of a failure to load and run the IP Line 4.5 software, the Voice
Gateway Media Card defaults to the BIOS load. This load consists of a
prompt that enables commands to reload the IP Line loadware and reboot.
There are three known reasons for the failure to load the IP Line software:
• Not enough memory due to a faulty or missing SIMM.
• Corruption of the IP Line loadware image in flash memory.
• The escape sequence to boot from the BIOS has been inadvertently sent
down the serial line due to noise.
To determine the cause of the IP Line load failure, reboot and monitor the
booting sequence through the serial port. Capture the booting sequence to aid
in communication with technical support personnel.
