| * such as Abis RSL, PCU, VTY as well as by attaching to a MS L1 implementation |
| * using the L1CTL protocol/interface. |
| * |
| * You can run the tests with |
| * a) osmo-bts-trx + trxcon + fake_trx (without any hardware) |
| * b) any osmo-bts-* + OsmocomBB layer1 + osmocon (with real BTS hardware) |
| * c) osmo-bts-virtual + virt_phy (without any hardware) |
| * |
| * Some of the tests will only run on a subset of those three configurations |
| * due to limitations in the respective L1. |
