To work properly, each end of the network must be terminated so here I have added terminator plugs to the two extremes of the network.

I have used SJ Research Terminator plugs as these are the easiest to use with a T-piece net.

As an alternative, you could use Acorn powered terminator boxes by taking an extra Econet lead from the last socket to the terminator box. You could possibly also use Acorn passive terminator boxes in the same way.
