Splitter or Filters ?

 Filters are easier to use or install but are needed on every telephone device. With the emergence of ADSL+ and VDSL enhanced services like video, the POTS splitter might a better way to go. And you only need one spltter BUT a technician will probaly have to install it. If you are interested in a ADSL+ splitter check out are new site:

Using a DSL splitter to seperate data and voice

  DSL service can use the same copper path as an existing telephone line. Because they operate at different frequencies, the DSL service and telephone line can use the same path , as long as the two signals are separated. However, if the two frequency bands are not separated properly, telephones and other equipment such as modems and fax machines can interfere with the DSL service. DSL service itself should never interfere with the phone service, but the wiring and equipment added to support use of the line for DSL may become the source of phone service problems.

  If you have an alarm system, installing a DSL splitter has an additional advantage. An alarm system will require either a special alarm panel DSL filter for the connection to the RJ31X jack for the alarm system or a splitter to separate the DSL from the telephone service before it goes to the RJ31X jack of the alarm system. A splitter is the preferred option by most alarm system companies.

  A splitter is really a better solution because it allows you to connect the voice side to multiple jacks, does a better job of separating the data and voice frequency, and helps prevent cross-talk. A splitter requires a different cable/pair be used for the voice and data. However, if you use a DSL splitter, your existing inside wiring can be used for voice with little change and without filters at every phone.For any new cabling, I recommend using four-pair CAT5 cable. CAT3 would be acceptable for telephone and would actually meet the minimum specification for DSL, but the cost for CAT5 is not significantly higher and it is much better cable.
