The configuration of IDU 3 is similar to above explained GUI pages but with appropriate parameters
defined in Figure 101.
Example 7 – Basic 1+1 HSB/SD protection scheme
The basic 1+1 protection schemes ensure the correct data transmission over the microwave link in
case of specific HW block failure or receive conditions degradation.(multipath fading, ..). The
1+1 / HSB (hot standby) protection mode protects against system HW failures (hitless protects against
ODU_Rx, IDU_RxAFE, with short data drop protects against ODU_Tx, IDU_TxAFE). The 1+1 / SD (space
diversity) protects moreover against multipath fading. 1+1 / HSB mode uses usually one antenna
assembled by directional coupler, two ODUs are connected into this coupler. The 1+1 / SD mode uses
two antennas separated by specific distance with just one ODU connected into each antenna. Just one
transmitter is active in such protection schemes (second one is automatically muted). Two receivers
receive the identical signal and master IDU decides what stream will be used for final data
demultiplexing. The basic software difference between HSB and SD mode is that in SD mode with
