1150328 2010-11-04 08:41:00 Can anyone explain what the difference is between the two?

Also I have never used either one and then internet always seems fine. Would there be any point in me getting them if currently it seems to work fine without them?

Thanks

1150329 2010-11-04 08:43:00 Do you use a phone on the same line? Speedy Gonzales (78)
1150330 2010-11-04 08:46:00 some times I used the phone at the same time, but I have never disconnected or anything.

Just another quick question, what does a sky decoder use the phone jack for?

1150331 2010-11-04 08:48:00 Well if you hear a squeal when youre talking thats why you need a filter

I have no idea why a decoder needs the phone jack. I've never had one.

I think its when you want more channels or something (when you pay for more)

A splitter is what the techs at Telecom put on your line at the Exchange end, to split the voice call from the Broadband connection.
A filter is what you put on your end at the phone jack to filter the voice from the broadband on a dsl/adsl connection.

1150333 2010-11-04 09:55:00 Filters are what Telecom send you so you can do a "self-install". They have a low-pass filter in them which prevents the phone (or fax/Sky decoder etc) from unnecessarily terminating the high frequency DSL signal. They also provide an easy conversion from the RJ-type connector used by the modem cable to the BT socket used by the phone.
One is needed on every phone-jack that is in use.

They are often not very good quality and the DSL signal still uses the existing phone cabling.
Also, if you have a security alarm, there is no phone jack to put a filter into.

The best solution (though expensive if you have to pay to get someone to do it) is to install a splitter; only one is required and it goes in series with the entire phone cabling right up at the front of the house where the line comes in from the street - before everything including security systems. It is also a low-pass filter but normally has better performance.
Then you run a completely new twisted pair cable from before the splitter to your modem (no phones allowed on this)

The splitter avoids any problems with poor internal house wiring.

1150334 2010-11-04 11:28:00 Decoders have a ph connection so it can dial up Sky and report on various things or provide an uplink for an internet connection. allanl (1957)
1150335 2010-11-04 20:02:00 The decoders originally had a phone connection as it was used for the booking features for pay-per-view etc, not sure if thats still the case. You don't need it connected to use the Decoder. inphinity (7274)

A splitter splits the line at the point where the phone line enters your house. It means only one phone jack in the house is adsl enabled, and all other jacks can have phones directly plugged into them. The adsl enabled jack needs a filter (either a dongle, or it is placed behind the wall plate and there are two jacks)

A filter is the dongle. It can also be placed behind the plate so there are two jacks so it looks tidier.

A DSLAM is at the telco's end which separates the voice from data traffic.
