Issue Description

Whenever customer was making trail passing from WAO_2 OSN 7500 Mux, he was getting error "cross connection already exists", due to this the number of unoccupied XC count was increasing in WAO_2 OSN7500.

 

Alarm Information

Error " Cross Connect already exits" Error code 38702.

Handling Process

Temporary Solution (Work Around):
a)      First create service
b)      Then open the Node through NE Explorer.
c)       Go to Configuration >> SDH Service Configuration, then click on Query.
d)      After query process gets succeeded, then perform Trail Search operation.
e)      Check the trail in SDH trail management.

Permanent Solution: The time limit was incresed in file "libte_sdh.so". Procedure for installing the new libte_sdh.so file in U2000. In our case it was Solaris Hot Stand-by server.

  1. open my computer, input ftp://serverip, input user and password.

        2  Go to /opt/U2000/server/cbb/trans/lib/, copy the libte_sdh.so to your laptop.

       3   Go to /opt/U2000/server/cbb/trans/lib/, delete the libte_sdh.so file.

        4   Extrace the attachment to your laptop, and copy extrace file(libte_sdh.so) to Server opt/U2000/server/cbb/trans/lib/

        5  Modify the owner and  authority 755 of libte_sdh.so file.

        6   Restart SDH manager process.

 

Root Cause

During analysis we found that NE data was not getting sync with the NM layer and even after doing upload and consistency check, making trails from WAO_2 OSN7500 Mux was getting failed with error code 38702.

Further we found that this was happening because this OSN 7500 was taking time much longer than the  difined in the file "libte_sdh.so" and thus generating the error.
