Lab setup with Ericsson BBU 6630 to open source core network

I am trying to create a lab setup to perform LTE RF testing.
I would like to use an Ericsson BBU (like the BB 6630) and connect it to an open source core network (srsLTE or openairinterface).
Has anyone done something similar? I have the EPC from srsLTE running, but don’t know how to configure or commission the Ericsson 6630, nor where to find the needed software packages.

Any advice?
