The present invention relates to an OAM apparatus for a radio base station. The OAM apparatus comprises an OAM receiver configured for receiving an electronic code key. The apparatus also comprises a storage unit comprising a list of code keys of which at least one of said code keys is valid. The apparatus further comprises a processing unit configured for determining whether a received code key is comprised in said list and whether said received code key is valid, and for invalidating said received code key in said list for preventing repeated use of the code key. The apparatus also comprises an OAM transmitter configured for being in a silent unless activated. The OAM apparatus is configured for wireless communication with an OAM terminal over a wireless OAM link if it has been determined that the received code key is valid and if the OAM transmitter has been activated.

OAM apparatus for radio base station

A radio base station for performing radio communication functions includes a human-readable, semi-persistent overlay fixed to a surface of the radio base station. A nonvolatile memory stores a current operational state of the radio base station. The human-readable, semi-persistent overlay indicates at least with text characters or symbols on the current state. If the current state of the radio base station changes, then the text characters or symbols on the human-readable, semi-persistent overlay are updated to reflect the changed state. The indication of the changed radio base station state on the human-readable, semi-persistent overlay remains human-readable even if the radio base station is powered-down.
