You have the equivalent of a point-to-point link, with Tx on one device
connected to Rx on the other. When you have things set up as a
network, all the Txs go onto a bus that connects all the Rxs. The
transformers allow the signals to combine, and separate them for each
station.
But I'd expect you could just find some proper boxes easily and cheaply
enough; they're not rare, even here in the UK.
