After that, the received signal is fed to the antenna input of the first PP 6, the second PP 7, the third PP 8, the fourth PP 9, the fifth PP 10 in accordance with the frequency range in which the received RF signal is converted.

The selected group signal through BKKR 11 is fed to the input-output of the UTSS-E 12, where it is decompressed into several low-speed channels. The low-speed channels from the UTSS-E 12 device enter BKKR 11.

Dedicated channels are transmitted from BKKR 11 to the input shield 3. Data from the third input-output of the UTSS-E 11 is transmitted to the second Ethernet switch 18 and, in accordance with the IP addresses, are transmitted to the input shield 3 or used for transit to the first Ethernet switch 19 .

Information from the channels enters the BWSS 22 and then through the first communication unit 23 is switched to the first MTT 25, through the second communication unit 24 it is switched to the second MTT 26, through the PSV 22 it is switched to the third MTT 27.
