The connection details of the hardware in the lab are here in the below network topology diagram.
5G NR Control-User Plane Separation (CUPS) according to 3GPP & O-RAN
E1 interface specifications, leveraging fully-virtualized XRAN 5G NSA CU-CP & CU-UP that abstract from
any specific hardware, running with standard off-the-shelf servers.
R15 3GPP compliant
