We do have some history of RBS2000 support

+
    +
  • + +OsmoNITB has OM2000 implementation proven with RBS2000 + +
    • +
  • + +OsmoBSC inherits that, but breaks voice (no E1 in osmo-mgw yet) + +
    • +
  • + +OsmoBSC has pcu_sock interface for BSC-colocated PCU + +
    • +
  • + +Adding E1/TDM user plane support to osmo-mgw would enable using Ericsson RBS again + +
    • +
  • + +All that’s missing for low-cost macro BTS with Osmocm is an inexpensive E1 interface + +
