Home network questions... wiring DSL?

Hello all,

I'm in the planning stages of setting up my home network, and I have pretty much everything figured out - or so I thought. I have Charter cable currently, but they pushed me over the line this weekend, so I'm looking at DSL options. With that comes a dilemma... I'm running all of my CAT5 connections into a patch panel in the garage, and I'd like the ability to plug the DSL modem into any room in the house (with the proper filter installed). How would I do that? Any sites out there that show basics for wiring phone systems?

Sorry if this is confusing, I'm getting confused myself... 🙂

The way you want to set it up is so that the DSL modem is connected to a jack that is unfiltered. Then, you have to put a filter on everything else that is hooked up to that same phone line.

The basics for wiring a phone system are pretty simple, you only need 2 wires to for a phone line, and polarity doesn't even matter, so you can't wire that wrong. And if you want to add a phone to the system, you simply branch those 2 wire off.

One thing I don't understand exactly, is where is the dilemma in the fact taht you're running all your cat5 to your garage? Is the CAT5 for phone, or is it setup for ethernet?
 
The DSL Modem needs one input from the Tel. line the Output is CAT5 Ethernet.

If you have CAT5 connection in most of the rooms you do not need to move the DSL Modem around. In your case you should have a Tel. line in the basement, put the DSL Modem and a Cable/DSL Router near the patch panel, and connect the DSL Mode to the Tel line and the output to the Router's WAN input. You Network goes into the switch ports of the Router.

The Filter does not go on the DSL modem. It has to be installed on all Phones, Answering Machine, DialUp Modem, Fax, etc. that are connected to the line with the DSL feed. Or if you run a special line from the Telco NID to the basement, you can put one filter on the line that goes to the rest of the house, thus eliminating the need for individual filters.

Ignore the prices in the links above. The same or similar hardware can be found for 60%-90% less.

In case your DSL is PPPOE.

On PPPOE:

PPPOE software is a "Dial in Type"; it initiates and keeps the connection alive while you are surfing.

The implementation of the PPOOE software used by most ISPs is unfortunately quirky, and with ICS it is VERY Quirky.

I would suggest to any one with PPPOE DSL to buy a Cable/DSL Router even if they don't have a Network. You can find Cable/DSL Routers on sale and rebates for $10-$20.

For the price you get Hardware Firewall, and Hardware PPPOE "keep alive", DHCP server, 4 ports Switch, and more

Unfortunately most DSL ISPs do not give you an ID and password over the phone; they want you to get it online.

In such a case use single computer connected to the DSL Modem. Install their PPPOE software and establish an account. In the process you will be given ID and Password (write them down)

Once you have an account connect your Cable/DSL Router to the DSL Modem, and plug your computers to the Router.

Log onto the Router's configuration Menus. In the PPPOE menu type Username and Password, make sure that the PPPOE option is checked. Set the Router to obtain IP automatically.

As long as you don't switch off the DSL Modem, and the Router you are connected "forever" (the computer can be switched off). If you switch the Modem, and the Router off, when you switch them on again, it will take about 30-50 seconds to the Modem to obtain connection, and the Router will automatically connect to the DSL ISP.

You can uninstall WINPOET, and or whatever software they dished you.
Or if you want you can leave them installed; (The software PPPOE appears as another Dialup connection, in the Browser). Just make sure that the Internet Browser is set to use LAN, otherwise it will keep using the PPPOE.

The Router's PPPOE capacity is independent from the Computer, and it keeps the connection alive.

In case of PPPOE DSL Working through the Router should yield faster (5%-10%), and smoother Internet connection.

=============================================

When every thing is done do not forget to optimize you TCP/IP for DSL connection.

Download DrTCP: <a target=new class=ftalternatingbarlinklarge href="http://www.dslre
ports.com/front/DRTCP021.exe">http://www.dslreports.com/front/DRTCP021.exe</a>

Run the program, it will show the current settings of TCP/IP parameters. Write them down.

You can change any variable that you want, click Apply, and reboot the computer, if no good; you can always change to your original values.

Start with:

MaxMTU - for DSL =1492

Tcp Receive - 255552

Window Scaling - Yes

Time Stamping - No

Selective Acks - Yes

Path MTU Discovery - Yes.

Black Hole - NO

Max Duplicate - 2

TTL - 64
 
Doh! I was editing that post and I think I left out a few things... 🙂 Basically I want to be able to plug the DSL modem into a jack inside the house, rather than locating it in the garage. That would make it easier to reset if necessary. Is that even possible? In theory (I think) putting the modem in the garage would require running a line from the demarc on the outside of the house to the patch panel and then from there to the modem, but I'm not sure how I'd configure it such that I could plug the DSL modem into a designated jack INSIDE the house...

Ok, I'm guessing that the way your phone lines are setup is that you have one line coming in, this line will carry both the DSL signal, and your phone signal. Then this line gets "branched off" to all of the jacks in your house. What you will want to do, is take the DSL modem and plug it into the jack of your choice, then you will put a DSL filter on ALL of the other jacks that have a phone/fax/other device hooked up to them.

Unless your phone wiring iss done in a completely different manner, this is what you will need to do.
 
You could just run the phone line from the telco demark directly to the location for the DSL modem. At the telco demark, you can then install a single filter on the line that goes to any other phones for that connection, and avoid having filters on each phone.
 
yeah, that'll work too, that's what I did, actually. That would definetly be the easier way, assuming you have all the jack running back to a punch down block.
 
It's very easy to just get a cheap ($20) router, plug the modem into the wall and into it, and all the cat5 into it. Most routers have support for xDSL PPPoE.
