Ericsson Baseband and Digital Unit hardware

Ericsson baseband hardware uses the `KDU` and `KDV` product-number prefixes, with the marketing name giving the generation and capacity class — Baseband 5216, Baseband 6630, DUS 41 01. In the DUS and DUG names, the two-digit groups distinguish variants rather than expressing a specification, so DUS 31 and DUS 41 differ in capacity and supported technology and are not simply revisions of each other. Where a listing shows a second product number, it is normally an included subassembly such as a fan; both are given here so you can confirm what a quotation actually covers.

State the technologies the unit must support — GSM, WCDMA, LTE, NR or a mix — and the number of cells and carriers, because these determine capacity class rather than the model name alone. Confirm the RBS cabinet or enclosure the unit fits and the software release running on the site. Ericsson basebands are tightly coupled to both the radios they drive and the release they run, so a unit that is nominally a step up can fail to commission. Where you are replacing like for like, quote the KDU number from the existing unit's label.

DUG and DUS units are end-of-support and available as refurbished or new surplus only. The Baseband 5000 and 6000 series are largely end-of-sale but well represented in the surplus market. RAN Processor units remain current. Per-line status is given in the table.
