Ericsson KDU137533/421 DUL 20 01 LTE baseband digital unit for RBS 6000. Tested and in stock at Tech-Star.

The Ericsson KDU137533/421 is a DUL 20 01, an LTE baseband Digital Unit for Ericsson’s RBS 6000-series base stations. It provides switching, traffic management, timing and baseband processing for the site, and interfaces to the Remote Radio Units (RRUs) over optical connections, following the distributed baseband/remote radio architecture used throughout the RBS 6000 platform. The DUL 20 01 includes power (-48V DC), GPS timing (RJ-45), Enclosure Control Bus, auxiliary and Local Maintenance Terminal connections, alongside Ethernet transmission interfaces, and is designed as a hot-swappable subrack card so it can be serviced without taking the wider site offline.
