Hola! I'm having a problem getting a MTP3 link up. I'm not sure what SLC should be used but if I do the ss7_add_link with slc=1, it fails like: (my PC is 5000, adjpc is 7000) STD_TEST OPC 5000 DPC 7000 SLS 1 H0: 1 H1: 1 STD_TEST OPC 7000 DPC 5000 SLS 1 H0: 1 H1: 1 STD_TEST OPC 5000 DPC 7000 SLS 1 H0: 1 H1: 2 STD_TEST OPC 7000 DPC 5000 SLS 1 H0: 1 H1: 2 NET_MNG OPC 5000 DPC 7000 SLS 1 H0: 7 H1: 1 TRA NET_MNG OPC 7000 DPC 5000 SLS 0 H0: 7 H1: 1 TRA (not recognized) And if I use slc=0, it fails like: STD_TEST OPC 5000 DPC 7000 SLS 0 H0: 1 H1: 1 STD_TEST OPC 7000 DPC 5000 SLS 1 H0: 1 H1: 1 No siganlling link available sending message! STD_TEST OPC 7000 DPC 5000 SLS 1 H0: 1 H1: 1 No siganlling link available sending message! Am I missing something? Thanks! -- Horacio J. Pe?a horape at compendium.com.ar horape at uninet.edu
