If that were me, I'd be tempted to have a gentle prod and see what's connected and what isn't, and to tidy the spare wires out of the way.
BUT they're solid core wires, and are liable to snap from too much flexing, which will cause you unending misery trying to get it fixed, so I'd
really recommend against this.
It's just that I like tinkering and fixing stuff, so it'd annoy me
However, your earlier question about XF-1e filters :
If you're already using a filtered NTE5 socket then you don't need any extra filters anywhere, even if you had working extensions correctly wired from the NTE5 - all the filtering happens at the NTE5.
It seems to me from your pictures and what you've said that there isn't anything else you could do to improve your setup.
I take it that the modem is quite close to the NTE5 (ie nice short cable) and away from other sources of interference (power supplies, LCD TV/monitor etc)?
