2500 ABORT Internal System software Error
1. Retry at 1-minute intervals a maximum of 5 times.
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 test #103 failed, follow the external modem recommendations for
that test failure.
2. If Test #103 passes:
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.
PASS MTP detected correct data from the external modem. The MTP received
an OK response after sending the AT command to the 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. If an
external modem is being used instead of the internal MTP modem,
modem settings may be wrong. Approved external modems with
factory default settings are expected to work if administered
correctly using the change system-parameters maintenance
command.
