cablemodem to telephone line via splitter?

As the above answerer's have pointed out,

you have messed n mashed up things

find below a simple diagram,

i guess u mean a fax modem / modem for dial-up,

^ above diagram should answer you, in that case

rj45 term is correct > ethernet

rj11 term used for telephone connector

are you through ... ?

You can connect the cable modem to the PC, but the phone line (48V) will probably burn out your cable modem... so don't do that! The connectors are different for a reason.

Your cable installer should run a coax cable to where you want your cable modem, which looks like it will be physically where the DSL modem is now. This is pretty painless. It is easy enough to run your own cable but the installers are quite fast. You will wind up with an extra phone line, use it to floss your teeth or plug in your analog modem if it makes you feel less wasteful. =)

Add: cable modem will probably only have ethernet ("rj45") output, which is all you really need anyway. The USB connection (and your DSL modem will be USB, not firewire) is not doing much if your ethernet is connected.

I assume since you are trying to connect both a cable modem and an ADSL connection to your computer, you are attempting to double your internet connection speed. You can't connect it directly with a splitter, but there are ways of accomplishing this:

1. You can purchase a dual WAN router and connect both the ADSL RJ45 and the Cable modem RJ45 to it and it will make use of both. Here's a couple for example: http://www.amdpower.com/sections.php4?op=viewartic...

2. You can also use dual NICs in your PC and get them working in tandem using NIC Teaming. Make sure the network cards you look for are capable of NIC Teaming beforehand. This method is trickier to configure, but less expensive.

The advantages of fibre is that it is not affected by ElectroMagnetic Interference, the way that copper wire is affected. Usually fibre has a lower error rate than will copper cable, that is not to say that some fibre installations are not prone to errors, just that they tend to perform better. But as someone said the network infrastructure also plays a role in your performance. The last part that plays a role is the wiring inside the house, that can be a major problem with copper as many people do not understand the importance of their house wiring and the installation of the fibre and the devices usually means that new house wiring is installed. If the connections to the telephone lines had been inspected and problems corrected, then the response may have improved drastically. As a couple of people say, they had much better service with fibre than they did with copper cable connections. You may experience the same. But I also know of people who have fibre and are very unhappy with their service. You may experience the same. I would suggest that you talk to neighbours that have fibre and get their impression, then you will know how it works in your neighbourhood. Good luck.

No. Cable modem is completely and utterly different to ADSL.

Don't even try and connect the two.

Also, USB is not Firewire.

Don't think that'll work. A cable modem wouldn't work for ADSL/DSL services from phone line.

Answer is NO.. to all your questions
