There is the SCCPlite variant of the A-interface, which osmocom supports, but it is not in any active use that I know of. See - 4.2.2.1 BSSAP/SCCPlite - 5.4.1.2 Configure SCCPlite in https://ftp.osmocom.org/docs/osmo-bsc/master/osmobsc-usermanual.pdf I think you want to use osmo-stp when possible. > > Concerning MGW, is there a way to use our MGW ?

Maybe familiarize with this chart: https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_In_The_Box#Topology There is lateral MGCP between BSC->MGW and MSC->MGW, and RTP from BTS via the two MGW to the other call leg. > Concerning the Gb, do you think that it 'll work if we configure the Gb on a > real SGSN connected to the osmo-pcu, hosted on the osmo-bts-trx? it may work when you do the integration right =) It would help if you were more specific, instead of "our MGW", "real SGSN". ~N
