The Ericsson KDU137533/4 R1B is the DUL 20 01, an LTE baseband digital unit, at revision R1B. The DUL is the LTE member of the digital unit family: it performs the baseband processing for the LTE carriers a site runs and connects to the remote radios over fibre, which makes it the part that determines a cell’s throughput rather than its coverage. Units in this range appear at several revisions under one part number, and a site is normally restocked with the revision already installed because each is qualified against particular software releases. 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.
