pretty good, the fact that there was 2 six markers was kinda annoying but what did you put for that question about the link between the telephone exchange and that green box and the house, it was kinda ambigiuous by saying 'connectivity media'?

wireless to the house and wired to the exchange? I think the latter is correct but not the wireless, with wireless there is so much interference because they are on the same freq. which would mean that the calls would get inturrpted if there was someone else on the phone in the area. I put copper cable and then fibre optic
