Recommendations and instructions for unblocking the connection and operation of third-party ONUs for the ZTE C320 GPON terminal

To remove blocking from OLT ZTE C320, you need to connect the computer with two ports: a console cable and Ethernet, setting ip:136.1.1.1/24. On the OLT control board these are CLI and 10/100M ports. Additionally, you need to set up an FTP server on your computer with the necessary firmware files and patches located on it. The account for the FTP server should be as follows, login: target and password: 123456 (used by default on the ZTE C320).

It is recommended to use an FTP server as a server on Windows OS - for example Xlight FTP Server
