3 | [[osmobsc:|OsmoBSC]] supports a number of E1-based BTS models in addition to IP-based OsmoBTS and nanoBTS. This mode of operation is probably not used very much these days, due to dwindling supply of legacy E1 BTS hardware, but I (@falconia) hold the view that in certain aspects of TCH operation (particularly the path from TCH UL Rx to TRAU-UL frame output), some E1-based BTS should be used as a "golden reference" for most correct BTS operation, to be replicated in [[osmobts:|OsmoBTS]]. I am currently hoping to receive a donated Nokia InSite BTS, in which case I shall use that hardware for knowledge-gathering experiments documented on these wiki pages - however, I am also documenting everything I seek to test, so that these experiments can be performed by other community members with access to the necessary hardware. |

5 | Having an E1 BTS for development and testing will (of course) facilitate improvements to the quality of Osmocom support for such legacy BTS - but that support may not have much value if the hardware is rapidly becoming unobtainium. However, many of the experiments I have in mind are designed to extract knowledge that will be useful outside of E1 BTS support in itself: knowledge that will allow OsmoBTS to be made more correct in corner cases, and will be needed for correct and robust implementation of [[TFO]]. |
