Looking for documentation and/or protocol traces for Motorola Horizon BTS

It seems like I'll be getting my hands on some Motorola Horizon 1 BTS soon. Of course it would be great to add OpenBSC support for yet another vendor / model.

So if anyone out there has any information on Motorola Horizon, I would be more than happy. Information includes:

  • Motorola A-bis (Mo-bis) protocol traces
  • Motorola A-bis (Mo-bis) protocol specs
  • Installation manuals
  • Configuration manuals
  • Service manuals

Thanks in advance!
