i was wondering if using the inline pots splitter, the ones that the internet companies give you when they send out the modem that you hook up at the rj-11 wall outlet, is a better choice than installing an outdoor pots splitter in the NID. does one give better performance than the other? God bless!

Re: DSL Line Filter Question

This is a "no brainer" for me. I VASTLY prefer the single splitter and the homerun from the NID to the modem, it's as good as it gets. If you use the multiple filters, the DSL signal is distributed all over the house, and has a chance to pick up noise and reflections from all the house wiring.


Purchase a DSL splitter and install it at the telco NID (Network Interface Device). This is the place the telephone lines come into your home wiring, usually either in the basement or outside near the other utilitiy connections. Run a direct line from the DSL port on the splitter directly to the DSL modem. Connect all of the other phone instruments to the telephone output of the DSL splitter. All of the DSL analog side wiring should be CAT3 or better twisted pair from the telco service entrance to the DSL/ADSL modem. You can use one of the twisted pairs in CAT5 cable if you have that on hand.

This is as good as it gets for DSL installations, and will usually solve in-house wiring issues.

Here's a good detailed description of the process: DSL Wiring Upgrade Tutorial
