+## RAN (gNB) Configuration
+
+In a Linux Terminal, follow the steps below:
+
+**Step 1:** Configure the PLMN and TAC values
+
+The Public Land Mobile Network (PLMN) and Tracking Area Code (TAC) will be configured in the gNB (/home/dco1020/openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.conf) configuration file. 
+
+Figure below shows the part of the code that must be modified in the CU and DU files (lines 17 and 18). The parameters shown in figure should be modified according to the values present in docker compose in the "oai-amf" session (/home/dco1020/oai-cn5g-fed/docker-compose/docker-compose-basic-nrf.yaml). 
+

+
+Figure below shows the parameters that should be checked and passed to the monolithic configuration file: PLMN_SUPPORT_TAC (referring to "tracking_area_code"), PLMN_SUPPORT_MCC (referring to "mcc"), PLMN_SUPPORT_MNC (referring to "mnc"), SST_0 (referring to "sst") and the SD_0 (referring to "sd"). If the "sd" parameter is not in the monolithic configuration file, simply add it according to line 18 in previous figure.
