GTA | POTS splitter vs DSL Microfilter
Im really clueless about the difference between POTS splitter and a DSL Microfilter? Which is better and why?
Please assume that a single microfilter is installed in such a way that it filters ALL the telephone jacks at once. |

The nice thing about the POTS splitter, everything is integrated into one tidy package. In fact, I've seen some that have RJ11 jacks, and you can plug your modem directly into. How about signal quailty? how is it affected? |

| Less connectors and cables == Less interference
Now, whether or not it makes a difference, I would doubt it very much.
I was more interested in the POTS splitter, because I'm kind of anal when it comes to wiring. I like to have it all tidy, and having the inline filter seemed to complicate things.
Although, I'm pretty happy with what I've got now. |

The do not seem to be any available on eBay right now but the Siecor I got there a couple of years ago (for about $10) fits nicely in a standard electrical box. That is much more secure than the DSL filter I had hanging off the demarc before. And of course, with RJ-11s on the splitter I can easily plug in a modem for testing. |

I used to have filters on all the telephone jacks in my house, and every time somebody called, my Internet would lose sync. It happened right after the first ring, when caller ID information is passed down.
I went out and got a POTS splitter from TekSavvy, installed it, and haven't had any problems at all. If you can easily install it, I recommend it over using filters. It'll make your life so much easier. |

Why buy a pots splitter? If your good enough inthe DIY department just hack a regular filter... for best results id recomend opening up the filter and soldering solid copper wires to the electronics inside instead of using that crappy phone wire. If you want to do something easier that will still work just plug a phone cable in the other end and strip the wires.
As for the installation.. Split your copper pair (the one from bell) at the demarc, put a filter on one of the pairs on the split that you will use to feed your phone jacks and the other pair on the split goes unfiltered to your modem jack.
I think the only difference between a regular filter and a pots filter is that it also filters out the phone signal from the line you send to modem, and im not even sure about that one.
Either way i know it works ive done it before.
Please correct me if im wrong about the pots splitter and filter diferences. |

| What i did since i Didn;t feel like filtering my whole House is I created an Indoor Second Demarc Like the oldstyle, All bells Lines go to it and beside it is a jack where i can connect to my internal Wiring. I simply Can Filter Once right there for all jacks.
But i actually use it for Voip  Dsl Signal into Modem in closet Modem Into Voip Router, Phone cord to Internal jacks connecting all My wiring to Vonage, At once I also have several network cables Runnin to Nic Jacks thruout my home which all go into the voip router. I wonder if the Tsi Modem w/ voip would work on Vonage. to eliminate one box. |

I used generic filters ($10 for a pack of 5, really simple passive LC filters) here with four phones and have no problems with my modem going through an APC SurgeArrest - other than losing about 3dB SNRM. Then again, I am on a sub-800m ADSL loop and this would solve most people's crummy wiring ADSL problems. |

If you are doing an indoor install, you probably want the CPE-01, as it has both screw terminals AND RJ11 for the line, phone, and modem. It will give you a very slick install. It seems the NID-01 only has 1 hook up for each. (Judging by the pictures here):

(You'll also note the mention of duct-tape.)

POTS splitters are far better then using filters because they split the DSL signal onto a separate pair inside the residence. Every device you plug into a phone line adds noise and loss to the line, potentially weakening the DSL signal.
There are actually different kinds of POTS splitters as well.
The kind I prefer (cost around $80) are installed externally (although mines in my house) and you will have no dial tone on the DSL jack.
There are other POTS Splitters that still work well but you actually get an unfiltered dial tone on the DSL jack as well.
In my home I experience a 9% difference in overall line capacity and a 11dB gain on my noise margin (specifically on the down). Went from 10dB to 21dB.
Notes about my configuration: Have multiple cordless phones.
Have a 900 MHz (really bad offender) and a 2.4 GHz. Plus a couple of direct-line/hard wired, not physically wired into the phone lines, just normal/old plugged in phones.
I had multiple filters plugged into the 900MHz in order to help reduce the effect it was having on the line. I had 3 plugged in.
Anyway, help this helps you decide.
