FAIL SYSAM reported test failure. The SYSAM did not receive an “OK” response
after sending the “AT” command to the modem.
1. If the Analog Looparound Test (#917) failed, follow the external modem
recommendations for that failure.
2. If the Analog Looparound Test (#917) passes:
a. Check the RS-232 connection from the external modem connector to
the modem. RTS and CTS signal are being communicated between
the SYSAM DUART hardware and the modem hardware. Transmit and
receive signals may not be communicated correctly.
b. Check the modem administration using the change
system-parameters maintenance command, especially changes from
default parameters.
c. Check the modem settings, especially changes from factory defaults.
NOTE:
The fault may be on the SYSAM circuit pack. The circuit pack may
need to be replaced.
PASS Modem administration matches SYSAM capability and SYSAM detected loop
current on remote access port.
1. If system cannot call remote maintenance facility or remote maintenance
facility cannot contact system, check with local Central Office for
problems with SYSAM remote access line.
