Fig. 1.1-2 Structure of Remote Stations
Remote stations should cooperate with the macro-/micro-BTS to achieve the BTS
functions, so you need to configure Local Fiber Module (LFM) on micro-BTS or
Optical Interface Module (OIM) on micro-BTS for interworking with the remote
stations.
If the LFM is configured in a macro-BTS, the connection between the remote station
and the macro-BTS is illustrated in the following figure.
