ADSL Modem Router Wireless Networks
DSL Modem Wireless Router:
Digital Subscriber Line (DSL) originated as part of (ISDN) Integrated Services Digital Network back in the late 1980’s.
At the time it was one of the first attempts for increasing the speeds of “Dial-up”, but for most subscribers ISDN stood for “It Still Does Nothing”.
DSL modem wireless routers are provided by your telephone company as part of their DSL Internet service installation.
WHNME is going to explain in detail the different types of DSL lines available and help you to understand how it differs from Cable Modem Wireless Router Internet service.
Over the decades technology has advanced and grown to achieve higher goals which broke through new barriers.
Today it has evolved into many flavors of DSL, the most popular being ADSL for Asymmetric Digital Subscriber Line.
Any of these suggested DSL Modem Wireless Routers will be a fantastic addition to your wireless home network configuration.

How does DSL work:
DSL works by your telephone company broadcasting an Internet signal over the same telephone line you use to make phone calls to your friends and family.
This works because natural human voice tones can be carried in a low end frequency range of 0 to 3,300 Hertz.
The two standards for ADSL are:
- The earlier carrier-less amplitude phase system
- The more commonly used standard being used today called discrete multi-tone (DMT).
Regardless of which system is implemented in your service area, both systems use the higher frequency range from 240KHz to approx 1.1MHz for the up and downstream channels for Internet data transfer.
After the DSL service has been activated, and the Internet signal is being sent over the customers current phone lines the only thing that’s needed is the equipment.
At the consumers end is the DSL modem wireless router, and depending on how service was setup may include DSL line filters (which we’ll cover in a minute.)
The DSL modem router wireless equipment referred to by the phone company as the ATU-R or Transceiver, is the access point where the customer wireless home network connects to the Internet.
On the ISP’s end of the Internet connection is the DSL Access Multiplexer, which is a network device that connects multiple customer lines into a high speed trunk that connects to the wide area network (WAN), also known as the Internet.
Understanding What’s Better… ADSL or Cable?
The difference between cable modem customers is that they usually share a network segment that runs through a neighborhood, meaning when more customers are being added the or all the consumers are online simultaneously Internet performance suffers.
A DSL modem wireless router customer will have a dedicated direct connection to the DSLAM at their ISP, so users won’t see a performance drop when new customers are beings added in their service area, and only see performance degrade when the customer being added is located far away from the ISP’s DSLAM.
Do I need DSL line filters:
Depending on how you had your DSL Internet service installed you may need to have DSL Line Filters attached to RJ11 phone jacks throughout your home.
If your unsure if your DSL requires the use of line filters, the following will clear things up for you.
You NEED filters if:
If your DSL modem wireless router was mailed to you by your ISP, you will most likely receive DSL line filters in the box when the DSL modem arrives.
The filters referred to as “low pass filters”, do exactly that! They allow low end frequencies below 4KHz to pass through the filter, and all frequencies above 4KHz are blocked out.
Meaning only voice frequencies get through, so you don’t hear the irritating digital sounds of the Internet signals beings broadcast into your ear as you pick up the phone to dial out.
You will need to attach a DSL line filter to every RJ11 (phone jack) in your home that’s being used for voice calls, fax machines, voice modems, etc.
The only device that WILL NOT have a DSL filter will be the DSL modem (transceiver) itself.
You DO NOT need filters if:
DSL line filters are not needed if a technician made a service call to your home, and installed a splitter at the phone box on the side of your house.
The splitter divides the analog phone signals from the digital Internet signal onto separate lines.
One lines feeds to all the phone jacks into your home, and the other goes straight to the DSL modem.
Which service is right for me:
Cable and DSL have been battling for over a decade. They both bundle services, and other promotional deals in which seems like a never ending fight to gain more customers using their technology.
In reality both services are about the same speed, and were DSL performance degrades the further you get away from your ISP’s DSLAM, cable modem performance suffers when more people are added to your segment.
That’s it! Whether you choose DSL or Cable, they’re both great choices for Internet service.
