Dear friend!
Your device belongs to the Copper ADSL access terminal of ISP.
Huawei ADSL access terminal needs to be used with Local terminal equipment and network management. The version must match the model. If the wrong version is used, ADSL will not work.
If you need to download firmware/software, we suggest that the best way is to contact the operator or sales channel to obtain the correct ISP firmware/software.
