PR-MAINT (Maintenance Processor [TN2404/TN790
RISC Systems])
Issue 4 May 2002 10-1383 555-233-123
FAIL MTP reported test failure. The system is not able to reliably
contact INADS with alarm data. However, the system
continues to provide good service. The MTP did not receive
an OK response after sending the AT command to the
modem.
1. If the MTP Outpulse Relay Test (#102) is also
failing, check for the presence of the inads trunk
and resolve any inads trunk problems.
2. If Test #102 passed, and if Test #103 failed, follow
the external modem recommendations for Test
#103 failure.
3. If Tests #102 and #103 passed:
a. Check the RS-232 connections from the DCE
terminal on the switch to the DTE terminal on
the modem. RTS and CTS signals are being
communicated between the MTP 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.
!
CAUTION:
The fault may be on the Processor circuit pack. The
circuit pack should be replaced. Note that if you
replace the Processor circuit pack, you need to obtain
a new license file.
