I think you mean star-wired and daisy-chained as opposed to in-parallel and in-series, and the normal way of wiring is daisy-chained.
Because each cable usually has 2 pairs present, this means that back-wiring is possible to make any extension the master.
Alternatively, a data extension socket can be fitted from the master to a location up to 30 metres away, for the modem. This should not be used for a phone extension.
Of course, it it still possible to use microfilters and use any extension as the modem socket just like with ADSL, but this could impact your speed and reliability.
