Any idea? Need to use dsl and dial-up at same time with only 1 phone jack.

My computer room is 20+ feet away from the nearest phone jack in my apartment.
I run a 24ft phone cord from the jack to my dsl modem.
For work, I need to make a dial-up connection.

What would be the most convenient/quality-preserving setup for this?

Actually the only setup I can think of is to get a y splitter, plug it to the end (the end that currently plugs to the dsl modem) of the 24ft, and connect 2 more 6 ft phone cords, 1 to go into the dsl modem, 1 into the 56k modem.

This dialup use will only be occasional. I don't want my highspeed to suffer too much for it.

Any thoughts?

I'm curious why you need to use dial-up if you have dsl actually.

And yes I agree that your idea is probably the simplest one. Don't forget to filter the 6ft cord going to the 56k modem.
 
Two points.

1. Set IE to Dial Up when network connection is not available.

2. DSL optimal MTU is 1492, DialUp is 576.

Set the MTU to 1492. Dial Up will work at 1492, but if you need to use the DialUp for downloading you will have to set it to 576, it takes few seconds to do it with DrTCP, keep a copy just in case.

Download DrTCP: <a target=new class=ftalternatingbarlinklarge href="http://www.dslre

I don't fully understand it myself but the software they use for security over the internet is expensively licenced and is not for anybody (we have one laptop that circulates that can use the internet to connect but it only when you're on call.)
But directly dialling is an easy way to keep things secure so anybody can do that.

Soybean - Thanks for the tip - I hadn't thought of that.

Jack - thanks too for your tips but why Set IE to Dial Up when network connection is not available? my dsl connection is always available.

What do you mean by downloading? FTP? Everytime a hit "Enter" something is downloaded or streamed. I'll only be using dial up to use a tcp3270 emulator.

am I going to be able to surf with IE over dsl while using the emulator over dial up without confusion?

I'll have to give this a try when I get a modem and install the emulator.
 
I've seen most DSL termination devices actually have a place to plug in a normal phone/modem to them - Check yours, it might well have a port for just this use.

The dialup won't affect the DSL in any way as far as interference. Dialup modems use the same voice frequencies that talking on a phone does, DSL uses different frequencies. A simple splitter will not affect the performance of the DSL much either, unless you were on the outer edge of the distance limitations. A filter will be needed though for the dialup line, just like if you were connecting a phone to another jack.

There were some other threads about this in the past couple of weeks, as far as controlling which connection is used. The issue is that if you have a dialup connection configured, much of the time when you try to go to a website, IE will try to use the dialup for its connection rather than the "LAN" connection over your DSL.

The solution I found, which I'm not sure worked or not since I don't actually have a dialup configured, and only applies to WinXP/2k, is to go to the Network Connections tool (on the start menu, Settings), and on the Advanced menu, select Advanced Settings. There you can specify the order that each connection will be used by software when it needs a network connection. After your dialup is configured, you should see both the Local Area Connection and the dialup connection (and possibly others), and just move the Local up to the top of the list.

Whatever software you're using to reach your work machines should then simply be specified to use the dialup connection for its access, which should be automatic when you install and set it up. All other software that normally uses your browser settings should still use the LAN as their default. They'd only try the dialup if the Ethernet went down.
