Connecting Ericsson BBU to Huawei antenna

[Malo_Mamalp]

Hello dear friends,
We ran into a problem and I had a question for you. If you could help us, I would appreciate it. We connected an Ericsson RRU8863 to a Huawei antenna with the following specifications. But we have calibration port and RSSI in the alarm system. Can you help us how to fix this alarm and where is the problem?
Does anyone have the experience of connecting the BBU Ericsson to the Huawei antenna? Is this possible?

I take it as TDD L23 cells. We have faced similar issue in past with RSSI on L23 and observed it’s due to synch issue. Try Connecting GPS to Ericsson BBU for synch.

I have used Huawei antennas with Nokia, no problems occurred. For 5G always use GPS for synchronization.
