| Looking for help on homerun/splitter installation
NID w/ splitter patched in on right side |
I have lots of big jpgs of the NID wiring which can help sort this out, but I don't want to post them all at once.
The splitter is attached on the right side through the orange/clear plastic connectors - not the white shrinkwrap connectors. The left side of the NID confounded me. I guess I thought that was where the "phone lines come in from the street" or something. Actually most of the telephones are connected to that side, completely bypassing my splitter.
You can also see on the left side of the NID, the use of a yellow and black pair of leads. That was something my splitter installation docs didn't prepare me for, and that probably led to me assuming the left side was the "in" side where Bellsouth wires came in from the street, and that the right side was "out" to the house. Those yellow and black wires lead back into the center telecom part of the NID, down low right where you see the yellow disappearing against the center, and they are matched on the other side of the NID by an additional red and green pair. On the left side, as it is easy to see the yellow and black pair connect to secondary posts on the terminal block. On the right side, the additional green and red pair are spliced to the yellow and black pair of the wire leading to the house via the large white shrinkwrap looking connectors. These "extra" wire pairs coming out of the center of the NID are I'm guessing part of the alarm system. Like the left side of the NID being wired up with a terminal block, these extra wires were something I didn't anticipate and couldn't account for in the diagrams I had to follow in connecting the Siecor splitter. I wired the splitter up anyway following the diagram as close as I could, and since there was sync on the new dedicated CAT5 drop to the modem and since all the phones still worked I called it a day. Only problem is that the splitter isn't doing the job it's supposed to. Sync interruptions are frequent.
What should I do? I have more pics to detail the NID wiring if they are needed. Can it be sorted out by the "customer" all on the customer premises equipment? Or is this something we should just call the phone company about and request that they properly install a splitter? Or should we call the alarm company and ask that they do it?
thanks for any help |

| The center of your nid should have 2 station protectors like this image
The phone lines from the street connect there
Your wiring should resemble this image when done

It's hard to tell from the pictures but you may have installed the filter and wiring but bound wires back to the regular wiring which would still let everything work, but in effect provide no split/filtering.
Have you looked at this FAQ?
»AT&T Southeast Forum FAQ »Siecor External Splitter Homerun Diagram
Maybe you would be better off having a tech install an internal splitter in the NID and bypass all the extra wiring and hassle.

You have one phone line, but it looks like you have two splitters. |

right side NID w/ mystery wires |
Left side of the NID connects some of the telephones on a completely separate wire. (In the overview shot in my first post you can see this sandy colored wire at the bottom of the left side of the NID, and the 2nd line which makes a right turn and enters the right side of the NID is light brown. The gray wire at the furthest right is the CAT5 wire to/from the splitter.) There used to be 2 phone numbers before my mother bought the house. I didn't know that at the time that installed the splitter. That was about 2 years ago now. The diagrams showed wires to the right of the telecom part of the NID so that's the side I worked on) If all that was the matter was that there were two runs of phone lines branching in the house I would know what to do about that. I would just tie the two house-bound lines to the dsl splitter using an extra twisted pair in the cat5 wire to/from the splitter.
I recently encountered the problem of 2 lines at my sister's house when I put a splitter on her system. There were 2 ph. numbers and 3 lines! The 3rd line was a shared L1 + L2 run. I sorted that out by using the brown/brown-white pair of my splitter wire to hook up the shared L1 + L2 line downstream of the splitter's filter. The orange/orange-white pair was connected in the usual way, I just did that step twice as it were. The orange/orange-white pair and the brown/brown-white pair tie down to the same "voice" posts in the splitter, but are spliced to separate lines into the house.
I would duplicate that arrangement at my mother's house, but that would leave the "mystery wires" that emerge from the lower center of the NID unaccounted for and unconnected. I suspect that they have to do with the alarm system, but I don't know.
You can see the mystery wires disappearing into the center of the NID clearly in this close up. These are the red/green pair and there's also a yellow/black pair on the left side of the NID which likewise emerge from the center "telecom" door. The yellow/black pair are visible in the master shot in my earlier post. The red/green pair on the right side are spliced to yellow/black on the light brown phone line that exits the bottom-right of the NID and enters the house. The yellow black pair on the other side of the NID are not spliced to the phone line on that side, but screwed down to the secondary posts of the terminal block. I guess that means they are "upstream" and the red/green pair which tie into the line going to the house are "downstream" but I don't know what to make of that.
------------------------------
on edit: About the FAQs, yes. It has been a couple of years since I did this, but I'm sure I was holding a print out of the Siecor homerun installation faq in my hand when I wired it up. As far as the splitter's basic installation, it's right according to the colored diagram, but wrong in its position within the flow of signal from street to the inside of the house. Because the line is connected to two terminal blocks the splitter is not upstream far enough. DSL signal is bouncing around in the branch of phone lines connected via the left side of the NID, causing I believe the sync loss problem. |

Only if there is a splitter (possibly an alarm system splitter) inside the telecom side of the NID.
There are two physical lines branching in the house and attached to two terminal blocks, left and right. Once upon a time there were two phone numbers - I didn't know that when I put the splitter on. There is only one splitter. Unfortunately since there are two terminal blocks and one splitter that means all the phones connected via the left side of the NID are branched off upstream of the splitter. When the phone company deactivated the 2nd phone number they did not rearrange the wires to tie down to just one terminal block. I'm sure it seemed like a good idea to the field tech at the time. |

First let’s keep this simple as I'm easily confused.
You have a two line NID but before I can help you figure this out you need to determine which side of that NID your service is provided over it's probably the right side but lets not assume.
Go to the NID and pull the jack out of the EBN on the left side of the NID and see if all and I do mean all of the jacks including the DSL jack in the home are working or dead and repeat for the right side. If one side kills all of the service to the home this is good but based on your post it will not so make careful notes of which side of the NID affects which jacks in the home.
Please post back your findings and we can go from there.

bottom of NID showing line 1, line 2 and Cat5 to/from splitter | 
Left Side of NID showing yellow/black wires from NID |
Here are the other detail photos I took. Line 1 and 2 are assigned arbitrarily since they are the same phone number. Colors I've used to describe them in prior posts are included to help keep it clear which line goes to which side of the NID.
It occurs to me that the yellow/black pair on the left of the NID which connect to the terminal block and then disappear into the center of the NID are possibly just left over from when there were two phone numbers. Maybe the previous owner had the ph # on the left side of the NID also available to some phones that were connected to the phone line on the right side of the NID. The yellow/black pair on the left attaches to secondary posts on the left terminal block, as if it were an auxiliary line to the house. But instead of going to the house it goes back inside the NID. On the right side of the NID 2 more mystery wires appear (red/green) and are spliced into the yellow/black pair of the light brown phone line fed by the right side terminal block. Depending on what goes on inside the center of the NID all that may only be a way of picking up L1 and feeding it to the yellow/black pair of L2. Although that really seems like going around Uranus to scratch your elbow. But if that's in fact what it was then it can just be disconnected now, since there are no longer two different circuits - just two lines for the same circuit. |

"you need to determine which side of that NID your service is provided over it's probably the right side but lets not assume."
Both sides have the same number. Both sides have the dsl signal, as verfied with a modem straight into the test jacks.
Half of the phone jacks in the house are fed by the left side terminal block, the other half by the right. The jacks in rooms closer to the NID are fed by the right side. The modem is attached to a dedicated cat5 run from the splitter, running underneath the house to the kitchen, and this run is also sourced from the right side of the NID. |

| said by oneirodyne  : The modem is attached to a dedicated cat5 run from the splitter, running underneath the house to the kitchen, and this run is also sourced from the right side of the NID. Then you need to do is disconnect what ever is on the left side and tie it in behind your already wired splitter. Make sense?
