Correct. Bad english. I do know how to wire it :-) But unlike having:

phone socket ----- double adaptor -------- adsl modem
                          |  
                          ------- little line filter ----- phone(s)

the hardwired unit has three sockets (or krones for hardwiring):

------ pair in from telstra ------ uber filter ---- adsl modem
                                       |
                                       --------- phone(s)

I looked at the PCB while the back was off (as you do) but I didn't pay
enough attention to see if the circuit was straight through between the
telstra line and the adsl modem. As well as having larger components (this
must be better :) I'm wondering if the uber filter has some high pass
signal conditioning to improve the adsl signal. Don't quote me; wild
speculation. 

Tim B said his unit cost $100. I think ours was $45 and is a plastic wall
mount box about 100mm(w) x 50mm(h) x 30mm(d).

I'd be surprised if they weren't getting cheaper. If anyone asks Lindsay's,
could they tell the list ?
