The Ericsson KDU137533/4 R2B is the DUL 20 01, an LTE baseband digital unit, at revision R2B. The DUL performs the baseband processing for a site’s LTE carriers and connects to the remote radios over fibre, which makes it the determinant of how much traffic the cell can carry. R2B belongs to the second revision series of this unit, later than the R1 builds that share the same part number, and the two are qualified against different software releases rather than being interchangeable on sight. Confirm the revision on the unit being replaced before ordering. Tech-Star (UK-based, shipped worldwide) supplies Ericsson base station components for ongoing maintenance projects.
