This Recommendation deals with lightning protection of Distributed Base Station (DBS) on the tower site. DBS is a new type of Radio Base station, which consists of Remote Radio Unit (RRU), located on the tower, and Base Band Unit (BBU) inside the shelter at the bottom of the tower. Lightning protection of DBS is not fully covered by ITU-T Rec. K.56. The main objective of this Recommendation is the lightning protection of RRU and rectifier interfaces with DC power cable, and bonding of the DBS. Protection of these interfaces is achieved by installing a protection module, and possible protection schemes for such installation are also described. This Recommendation indicates when these protection modules should be used and its withstand current. The SPD need on the feeder's cable is also indicated. Bonding configurations of the protection module and of the optical fibre cable are also illustrated. Appendix I shows an example of isolated protection solution.
