I understand this is a bargain site, but there are lots with various experiences and professions on here so thought I'd ask here first.
My wife has a new work-from home role (Nurse-on-call) and needed to have a direct nbn phone line and 4G backup so we've unfortunately had to move from AussieBB back to Telstra.
Every now and then the phone line makes lots of noise during the call and she then can't hear the other person on the line. The other person can hear her fine. The problem is not something that occurs all the time or on demand. The problem occurred a few times on Friday, nothing yesterday and once today. One time it rectified itself, but the other times she had to hang up and contact the person back again. Different people one the line each time.
I'm trying to narrow down where the problem is, low hanging fruit first so I'm replacing the phone cable tomorrow. I'm also wondering if it might be HFC cable related. E.g. I have an HFC cable with a splitter, so one end goes to the TV area and one to the office. This cable was once used with Telstra Internet / Foxtel and is now being used for the NBN. One of the ends of the HFC cable is not connected to anything. Is there supposed to be some sort of terminator plugged in the end or is it ok to just leave it open?
I see there are terminators like this, but I don't know what their purpose is and whether adding one will cause other problems. I didn't find any other info from a Google search regarding the terminators.
