The Ericsson KDU137533/4 R1F is the DUL 20 01, an LTE baseband digital unit, at revision R1F. The DUL handles the baseband processing for a site’s LTE carriers and passes the processed signal to the remote radios over fibre, so it governs the capacity of the cell rather than how far it reaches. R1F is one of the later builds within the R1 series of this unit. Because revisions are qualified against particular software releases, the marking on the unit is part of the identification and not merely a batch code. Check it against the unit being replaced before ordering. Tech-Star (UK-based, shipped worldwide) supplies Ericsson base station components for ongoing maintenance projects.
