Cable box splitter has two open spots but there are 5 unattached cables
Spitter on bottom left has two open spots. There are 5 unattached cables. Can I replace the splitter with one that has 5 open spots to attach cables?
Some of the blue cables on the right might be for land line phone connection. We haven’t had a landline for 11 years. Any guess what the 9 connections are for at top left?
