I have previously used ADSL line filters for non-ADSL equipment (phones, sky decoder) in my house. Now I have moved into a new house and in the study next to the phone jackpoint is another jackpoint with a sticker saying "ADSL" on it.
Does this mean that a central splitter has been installed for the house? If so, does that mean that I no longer need line filters on the phones, sky decoder etc?
If this is all the case, then I would also assume that I would connect my broadband modem directly to the ADSL jackpoint with no filter. However, the DSL port on the modem is the smaller RJ type (is that an RJ11?), but the jackpoint is the larger type (RJ45?). How should I connect these?
