2.1.4 Bottom of HROU
2.1.4.1 Functions
The Bottom look of HROU depends on the combine unit(CU) with 3 options.
The CU option1 and 2 need to install a specified CU in the enclosure like the table below explains.
Thus, the CU option1 has one antenna port, the CU option2 has two antenna ports.
Finally, the CU option3 with 4 antenna ports is not necessary to install CU in the enclosure and needs to
apply the panel with 4-DIN Type on the bottom of HROU.
See table and drawing below for.
