It is a MajorTech Veti modular system. Looks very nice, but for such expensive product I would expect cover plate to click and latch without using hammer.
I saw recently similar system of a different company in Communica Midrand. Also expensive.
You are right, it is illegal in South Africa to put power cable in the same conduit as a LAN cable. For this reason it is pointless to sell mixed power sockets with LAN. It would be illegal to sell it, I think.
As for Telkom cables, I would never put anything like that in the close proximity to the other (power/LAN) cables.
