multiple phones = slow connection??

Jan 25, 2011 6:32AM PST

Hello,

Thank you for taking the time to read my post and I appreciate any input you have.

The Problem: Slow DSL connection when I wire more than one phone.

I have one phone line coming into the home (red,green,black, yellow). I had to splice the line to get it to reach where I have my modem and router (in the basement). I spliced it with CAT5 and ran it near the modem. Before the line got to the modem, I spliced it a again with a small "plastic, triple phone splitter butt connector". From here, I ran one wire to a regular, module phone jack that I installed near the modem. The other wire I left to connect to multiple phone lines at a later date. I connected the main line to the phone jack near the modem and also connected another line to that phone jack (I ran this upstairs to the phone in the office). Ok, then I ran a phone plug from the installed phone jack near the modem, TO the modem itself. From here, I installed an SMC Barricade router. To this I have run two CAT5 cables, one to the office and the other to the bedroom (I plan to connect more lines soon).

Everything worked great! I was able to get the secured wireless connection working and even the hardwired office and bedroom LAN network connections to function. Awesome!

Ok, I now wanted to run the spliced phone line to multiple phones in the house. I bought an Open House H802, passive splitter and hooked the "main" spliced line into the end of the splitter and ran two more phone lines off that.

The internet connection slowed to a crawl! Frustrating. I called Open House and they were not sure why it was so. He recommended that I split the main phone line before it reached the modem, but I believe I had already done that. So, I disconnected the Open House splitter and resorted to my little "plastic, triple phone splitter butt connectors" (figuring is was something with the Open House splitter). To no avail. As soon as I hooked up the second phone, the connection slowed down.

Question: How do I connect multiple phones in the house, without compromising my DSL connection?

Thank you for your time.

Just wondering.

Why didn't you install the usual DSL filter before you sent the signal to to new locations?

cat5 splicing? What's that all about?

Ok, here is what I remember about DSL installations; telephone lines are separate from LAN lines; and for EVERY DEVICE (phones,modem,fax,etc) connected to the telephone line there should be a "line filter". Now recheck the connections. Good luck.

to all the Bell companies, here is some advice.

First, you've got it all screwed up, I'm surprised it works at all.

At the entrance to the home, the device is called the SNI (Subscriber Network Interface). This is where the DSL service, riding the cable pair in what used to be called DOV (Data Over Voice). At this point should be connected Cat5 wire. Period. The wire you describe, R/G/Y/Bk (JKT wire) is not designed for the high frequencies involved with DSL. (Your first mistake.)

This Cat5 wire needs to feed into the house and at this point the filter needs to be installed. DSL on Cat5 to one modem and voice on whatever you like. Doorbell wire will work. Split it however you want. Voice doesn't care.

In other words, DSL does not like splitting. DSL needs to run to the modem, and nothing else. This is called the home run, as in one connection (filter) run to one termination (modem).

it worked!

I found out the problem was quite simple (as suggested), I did not have filters at the phone jacks (I only thought they were to improve the quality of the phone line...I did not think they were necessary for proper DSL functioning).

When I installed the phone filters, I was able to surf the internet effortlessly.

As for the person who posted above, if it works, don't fix it! I will save your post and as soon as I run into a problem, I will rewire the setup, but for now, it is working just fine.

Thank you for all your input!

Oooooooo, assumption on my end . . .

The "filter" is actually a band pass filter. It splits the high frequency DSL signal away from the low frequency voice. You want to separate the data from the voice. See my explanation at my site if you wish.
