Questions regarding DU-Low and DU-High
|
Alexandru Moise
Greetings fellow engineers,
I started posing some technical questions to some of the active o-ran developers and I was pointed towards this mailing list. Q1: Does anyone here know if there's a DU-Low demo available anywhere? I found a DU-High demo that uses a cu_stub and a mac_stub, didn't find a DU-Low demo as of yet. Q2: Is is possible to run DU-Low in a simulated environment? Q3: Is o-ran at a stage yet where DU-High and DU-Low are integrated with eachother? I started watching some zoom recordings and as of april I think they were not integrated yet. Best regards and thank you in advance, ../Alex

The O-DU HIGH and LOW integration is targeted to happen at Bronze maintenance release (mid July), for which the two components will communicate with FAPI interface. Best regards and thank you in advance, ../Alex

[lji] This is best answered by the O-DU LOW team. [Zhimin] O-DU Low also provide two level test simulator to help L1 testing. We have O-RU test simulator, it’ll help the O-RAN FH interface verification. We have L2 test simulator(testmac) which can be used to bring up L1 for functionality verification and performance dimensioning of L1.
