Just looked at our new decoder... The old one broke (again) so sky came out and replaced it. We are now on our 4th decoder!

We never bothered to have the phone line plugged into it before. I just noticed that sky used their own phone line filter when plugging in the phone line, and its an ADSL filter that provides it the ADSL filter connection. I always presumed that it would use a free calling or local calling analouge line to use any data services. So does sky require an ADSL connection to use on demand or certain features? How can sky only offer this service to certain consumers if so?

Sky don't use ADSL. It's just a regular analogue modem.

ADSL filters don't go on modems - they go on every other analogue device on your line.

All, repeat all DSL filters are only required on Voice band devices that are connected to a line that also carries DSL signals. The Sky box only has a voice band modem not a DSL modem, the filter stops the boxs phone port from stuffing up your DSL connection.

Ok... Thanks... Not that we can receive DSL where we are anyway so I guess it doesnt make any difference... And not that any of the features that use the phone line work with the sky modem anyway... Typical. I wonder why the sky filter says ADSL filter then? Do DSL modems not require a filter at all?

I'm noty quite sure what you mean by the first line. The phoneline is used regularly by Sky and allows things like PPV to work without having to ring and order movies.

ADSL modems don't require a filter as explained above in both posts. Sky presumably install one with all new installs since they probably assume people either have broadband or may get it in future and so they'll save the homeowner the cost of a filter.

Correct, the DSL modem does not require a filter, it connects directly to the line, the modems do however have an inbuilt HiPass filter that removes the voice band from their hearing, however a DSL filter (as you have) stops voice band devices from effecting DSL signals and stops DSL signals from getting into them.

To try and help clarify for you, if you do not have ADSL then the filter makes no difference. If you do have ADSL then the filter ensures the analogue phone (and Sky modem) does not affect your ADSL performance. It is not a filter to get ADSL out of your phone line, it is a filter for use your analogue phones if you do have ADSL.

I'm curious, what faults did you have with your boxes? We're on our 2nd small silver box which locks up every now and again (when you change channels) just like our first one did. Apparently lots of issues with the small silver boxes.
