SSN Prohibited

  • We are configuring a SMLC with SSN = 252, but from the BSC side, they receive a PROHIBITED message as the following:

     

    eaw GBBRC2

    <c7ncp:sp=2-808,ssn=all;

    CCITT7 SCCP NETWORK CONFIGURATION DATA

    SP SPID SPSTATE BROADCASTSTATUS SCCPSTATE

    2-808 SMLCMAQ ALLOWED NCON ALLOWED

    SSN SUBSYSTEMSTATE SST

    252 PROHIBITED YES

    END

     

    Also, we have this error:

     

    Adding SCCP SSR fails

    S7MGT: FAILED

     

    Our config.txt is as the following:

    We would like to know if our configuration is correct and if not what we need to change.

  • Hi,

    In this case you appear to have 5707 configured as the only destination for M3UA and then 4278 configured as destination at SCCP.  For the RSP and RSS to become available a route to 4278 would be required.
