1. Check DATE & TIME fields matche with the current timing, where
DATE:YYMMDD (Y:year M:month D:day)
TIME :HHMMSSMS (H:hour M:minutes S:seconds MS:milli seconds)
2. Check from field NS1 which country code is it Refer to Appendix A
3. Verify the message originator by checking which network signalling point code in the
fields NI and OPC by using command C7SPP
C7SPP:SP=NI-OPC;
<C7SPP:SP=2-1220;

4. Check the existing international routing in our MSC's by using command C7GSP
C7GSP:TT=0, NP=1, NA=4, NS=CC; (CC is the country code)
Then get GTRC from the printout and check the GTRC routing by command C7GCP

5. Check the subsystem number from field SSN use Appendix C
6. The finally check the Cause of the problem by checking the value of the field CAUSE use Appendix B
Explanation:
This means that we sent an SCCP message to subsystem SSN with global title address
NS1 and NS2. But we received back a message from OPC indicating a failure with reason CAUSE
Open a trouble ticket for the department responsible for node indicated by the signalling point
(b) ENUM 208
1. Check the DATE and TIME fileds matche with the current timing where
DATE:YYMMDD
TIME: HHMMSSMS
2. Check from field NS1 which country is it refer to Appendix A
3. Check local subsystem number from field LSSN and the destination subsystem number SSN
use Appendix C
4. Check what was the operation from the field OPCODE2 use Appendix D
Explanation:
This means that our local node susbsystem LSSN tried to send an SCCP message related to
operation OPCODE2 to destination subsystem SSN with global title address NS1 and NS2.
This operation failed due to timeout so we did not receive any reply to our message.
Check with Gateways support is the signalling links to the destination country are working or not
and inform them about the received errors.
