Sometimes there is static on the phone line or the fax machine will knock off the DSL connection among a host of other things that could confirm a reason to installing a NID Splitter.
I am using a scenario that involves a generic 66 block that you find on most Demarks, a Suttle Outdoor NID Splitter and a 4 post telephone jack or biscuit.
First thing you need to do is find the circuit that the DSL line is sharing. Sometimes it's marked and sometimes it is not. That is when you need a butt set to test the circuit. Connect your alligator clips to the 66 Block and get a drop tone and verify the circuit by calling 1-800-444-4444. This number will spit back the phone number MCI sees on their end.
If you are on the correct circuit and there is no dial tone verify with the Internet Service Provider (ISP) that you are not using dry loop DSL. If you are using a dry loop DSL there should be no reason to install a splitter, but I've seen crazier things happen.
Please take a look at my other posting on how to make a homemade Lineman's head set or butt set in one of my earlier posts if you don't have one or yours is out of commission for the moment.
Once you find the circuit take a look at how it is being used. It could be used for just the main land line or possibly the fax line. Then you will want to run this first to your voice side in the splitter all the way down to the biscuit.
Verify that you have connectivity at the splitter on the Voice Posts with another phone or your butt set. This way you know you are getting an electrical current all the way from start to finish.
After that it is all down hill. Connect a run from the 66 block to the Data posts and connect your last run from the 66 block down to the network posts.
Below is a picture of one type of proper split set up.
I hope this makes some sense to those reading. It looked much better when I created it...
The 66 Block is labeled. The NID is between the two with the 6 posts on it. Those are the Network, Voice and Data posts.
Row 1 Column 2 on the 66 Block is using a Blue and White cable and Row 1 Column 3 is using an Orange and White cable. Row 2 Column 2 is using a solid Blue cable and Row 2 Column 3 is using a solid Orange cable. (Just for clarification)
The color of the cable DOES NOT MATTER. Just keep them the same for simplicity and future use. Make sure you label the jacks if they were not before. Remember this is just ONE of many ways to install a NID Splitter. It all depends on the situation presented to you at time of install.
