SBR Carrier signalware reports TC_CANCEL but snoop shows that HLR returns information



Article ID: KB22401 KB Last Updated: 05 Mar 2017Version: 2.0
This article describes the issue of SBR Carrier signalware reporting TC_CANCEL, but snoop shows that HLR returns information.
When testing SIM/AKA authentication with an HLR, go.omni reports a TC_CANCEL for the message returned from the HLR. But in a snoop, the HLR returns a valid message. 
 This issue will occur if the Omni stack was set up to use the mixed mode (AC7) protocol stack; but the HLR is using ITU (C7). It is recommended to use only the mixed mode, if you know that the HLR will be using ANSI (A7).
 In the $OMNI_HOME/conf/nodeConf.MGW.* file, change AC7TCAPmoduleNAME to C7TCAPmoduleNAME and restart Signalware.

AC7TCAPmoduleNAME TCMGlogicalNAME LNDtcapNotReady

Should be this:
C7TCAPmoduleNAME TCMGlogicalNAME LNDtcapNotReady
