Agent Greeting Card Maintenance and Troubleshooting Guide
Debug Terminal Access
The Agent Greeting Card Debug Terminal access is provided via an RS-232
port. This is accessible via the NTAG81CA faceplate serial cable. Messages
indicating the completion of each self test phase, as well as any detected faults
will be logged to this serial port.
The pinouts for the Mini-DIN Connector, to which the faceplate serial
maintenance cable connects, are given in Table 3 on page 15.
The terminal connected to the serial port requires these settings: 9600bps, 8
data bits, 1 stop bit, no parity, and no flow control.
Debug Features
While the Agent Greeting Card is booting, the 8051 auxiliary processor has
control of the serial port, and uses it to provide debug information, progress
of self tests, etc. Once the 8051 releases the main processor (i486) from reset,
the main processor by default grants VxWorks shell access through this port.
The Agent Greeting Card also supports remote access to the shell via telnet.
Once the card is operational, the RS-232 port may be used to monitor
CardLAN and Time Compression Multiplexing (TCM) signaling between the
card and the Meridian 1 system.
