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.
1. For an internal modem:
a. If MTP Outpulse Relay Test (#102) is also failing, check
for the presence of the INADS trunk, and resolve any
INADS trunk problems.
b. If Test #102 passes, the fault is on the Processor circuit
pack. The circuit pack should be replaced.
2. For an external modem:
a. Check the power to the modem.
b. Check the RS-232 cable connections from the DCE
terminal on the switch to the DTE connector on the
modem. Transmit, Receive, RTS, and CTS signals must
be communicating between the MTP DUART hardware
and the modem hardware
c. The MTP DUART or related circuitry on the processor
circuit pack may have failed. The circuit pack should be
changed at your convenience.
NOTE:
If you replace the Processor circuit pack, you need to
obtain a new license file.
PASS For an internal modem—MTP detected correct data through the
loop back connection.
For an external modem—The test detected correct data through
the loop back in the MTP DUART hardware ahead of the RS232
connection to the modem, and received a CTS signal from the
external modem.
1. If the system cannot call INADS, or if INADS cannot contact
the system, check with the local Central Office for problems
with the INADS trunk, and verify that the INADS number is
correct.
