Procedure 8-2: Performing the MISP self-test
If the MISP status indicates that the MISP is faulty, you should conduct the
self-test to verify that this MISP is actually faulty before replacing it.
To start the self-test, follow the steps below:
1 Log-in on the maintenance terminal and load overlay program 32
(LD 32).
2 Type DISC c and press the Enter key to disable the MISP card,
where c is the MISP card number you are disabling.
3 Exit LD 32 by typing **** and load overlay program 30 (LD 30).
4 Type SLFT c type and press the Enter key to start the self-test, where
c is the MISP card number and type is 1 for a detailed self-test and
2 for minimal test.
If the response is:
NWS637
the MISP card passed the self-test and is functional but must be enabled
to extinguish the red LED and to start processing calls. It may take up to
20 seconds to display this response.
If the MISP passed the self-test, but the problem persists, other cards that
interface with the MISP may be faulty. To verify the peripheral
equipment cards interfacing with the MISP, go to Procedure 8-3 and 8-4.
If the response is
NWS632
the MISP card failed the self-test and is faulty. Replace the MISP as
described in Replacement procedures. Other NWSxxx message may be
displayed as a result of a command activated self-test if the MISP is
missing or not configured.
Performing the MISP loopback tests
If the MISP self-test indicates that the MISP is not faulty, you should conduct
loopback tests to isolate the problems that may exist on the connections
between the MISP and the SILCs and/or UILCs.
