If you've just ordered DSL for your home or business, there are a few key things that you need to know.
The DSL signal will be active on your line, usually within 5 to 7 business days. During this time, if you elected to order the modem through IQuest, you will receive the modem kit from SBC via UPS. This kit will include 5 regular filters, 1 wall mount filter and the "DSL modem". You will be notified via email or phone, of your official "turnup date" and your setup information.
In placing the order you should have already determined how many DSL filters you will be needing. You will need a DSL filter in every phone jack in use on that phone line where you are having DSL installed. Any phones, fax machines or satellite receivers which dial "pay per view", will need to be plugged into the "phone" side of a DSL filter. Likewise, the DSL terminal adapter ("DSL modem") should be plugged into the "DSL" side of a DSL filter. You also should have been asked if you have an alarm system in place on that line. If you do, you must have a "NID splitter" installed on that line. You can contact the manufacturer of your security system to have the "NID splitter" installed.
Without the "NID splitter" your security system can conflict with the DSL signal on your line.
Now that you know how the setup should look from the phone jacks to the phones and "DSL modem", you should consider the setup from the "DSL modem" to your computer or computers. If you are going to be using multiple computers on your DSL line, you will need a "router". A router is an interface device that can route network traffic to multiple computers. So if you are using more than one computer, then the router would fit between the "DSL modem" and your computers. If you are only using one computer, then all you need is the "DSL modem".
