You cannot send a fax directly through a naked adsl connection. It is possible to send a fax over VOIP though to connect your Brother fax you wound need a pstn (telephone) port to connect it to. These are available on some VOIP enabled modems and specialised VOIP appliances. I haven't checked but you should be able to find one somewhere. I think Linksys used to make a few and providers like MyNetFone would often provide them with their service.
Having said this, I would not recommend it. I tried it years ago and was never able to get satisfactory results. I could occasionally get a fax to go through with error correction disabled but it was essentially unusable. From memory there is a protocol, T38, supported by some fax machines for sending over VOIP, but I doubt it works very well. Fax is essentially heading the way of the Dodo here as the NBN spreads.
