Fault isolation and correction using MMI maintenance commands
Some testing and troubleshooting of the Carrier Remote IPE can be done
from a local or a remote MMI terminal or TTY by typing MMI commands on
the terminal without loading system diagnostic programs (overlays).
These commands:
•
provide current equipment status
•
invoke card testing
•
check equipment performance
•
print messages from log files
At the TEST prompt, type 7 and press the Enter key to test
Remote Carrier Interface to Remote Carrier Interface through a
special loopback channel.
Continue responding to the prompts to configure the loopback
test as follows:
Command Range
7
TEST
PATT 0–7
TYPG P
TN l s 99 0
0–15
TAG x
Check the loopback test results.
The results are automatically displayed if XCON 0 test conditions
were specified; otherwise, specify XSTA or XSTP with the test
TAG number to check the status. XSTA obtains the status of the
manual continuity test. XSTP stops the manual continuity test.
If the results show BSDxxx messages, refer to the list and
description of these messages in Software Input Output
Administration (NN43001-611) (). The BSDxxx messages
indicate the possible causes of the problem, which should be
checked to isolate the actual problem.
If the loopback continuity test passes, the problem may be
somewhere in the IPE cards.
If the loopback continuity test fails, replace the card.
