I think you didn't understood me! I'm talking about this scheme: there is two SP (Signalling Point) with differrent PC (Point Code); SP1(PC=1) have SS7 link two SG1(PC=3) and SP2(PC=2) have SS7 different SS7 link two SG2(PC=4); SP1 doesn't have any physical connection to SP2, SG2!!!! but they have SS7-relations! What will be if the link from SP2 ot SG2 broken? Stan ----- Original Message ----- From: "Brian F. G.
