I am trying to validate some functionality of a BSC that we have. The BSC will be connected via Gb interface(over E1) to an SGSN. What kind of hardware(processor/E1 card) would I need to support the SGSN ? I am mainly interested in testing ns/bssgp functionality. Thanks in advance. Naveen

Can you provide some details about the BSC?

Pleaes note that this is the OpenBSC mailing list, after all ;)

OsmoSGSN has only two protocol stackings available: BSSGP/NS/UDP/IP and BSSGP/NS/FR/GRE/IP. As such, you cannot directly interface any legacy BSC (rather: PCU) without developing the respective NS-over-E1 related code first. If you choose to go down that path, I'd be more than happy to review + merge it into our project.
If you're running frame relay on your E1, you might use something like a cisco router that can adapt the FR over GRE/IP and then attach it to OsmoSGSN.
