You should know that the TRX connects to the BTS and that the BTS to the BSC. And you should know what the TRX, the Abis OML + RSL and the AoIP interfaces are and between which elements those interfaces are spoken. You alsao know the IP addresses used in your network, so the answer to the questions are obvious. You can also look at protocol traces to see which connections/flows exist between which programs / ports and then deduct the information from that. -- - Harald Welte <laforge(a)osmocom.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
