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

I think you want to use osmo-stp when possible.
Concerning MGW, is there a way to use our MGW ? At this time, with Osmocom
corposants, we can see RTP traffic between BTS-TRX and MGW, and some MGCP
traffic between (BSC - local MGW) and MGW, and some MGCP traffic between
osmo-MGW and osmo-MSC. Is there a way to have a "more standard"
architecture: no traffic between BTS and MGW, and MGW controlled by MSC ? Do
we have to more study TRAU, AoIP ?
Maybe familiarize with this chart:
https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_I…
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".
