What does China Telecom's error code -9 1 10 1 mean?

Due to the different brands and models of set-top box equipment used in different places, the error codes are also very different, so it is impossible to judge related problems through the error codes.

You can restart telecom broadband cats and itv set-top boxes. If this is still the case, I suggest you call the local telecom customer service directly to understand the relevant issues. You can call 10000 and ask the staff to check or repair it for you.
