Get your business up to speed with High Speed Dedicated Internet Access.

Internet Access > DSL

Concentric DSL provides fast and reliable Internet access to businesses that are in need of fast download and upload speeds, which our SDSL (Synchronous DSL) service provides. Fast download and upload speeds are critical for today's businesses.

Here are a few reasons why:

  • Transferring large files (FTP, email exchange, ...)
  • Document conferencing (WebEx, NetMeeting, ...)
  • Transaction processing (Restaurants, ecommerce sites, ...)

144 Kbps/ 144 Kbps IDSL IDSL stands for ISDN DSL, and is closer to ISDN download and upload speeds (128 Kbps) than to the much higher rates of ADSL and SDSL. Check Availability »
144 Kbps/ 144 Kbps SDSL SDSL (Synchronous Digital Subscriber Line) is a type of DSL circuit that provides the same download and upload speeds (hence the term "synchronous"). SDSL is generally more expensive than ADSL circuits because the upload speed increases the overall consistency and speed of the Internet connection. Also, you will have a better chance of getting SDSL service in your area because the distance required from your location to the provider is longer. Check Availability »
384 Kbps/ 384 Kbps SDSL SDSL (Synchronous Digital Subscriber Line) is a type of DSL circuit that provides the same download and upload speeds (hence the term "synchronous"). SDSL is generally more expensive than ADSL circuits because the upload speed increases the overall consistency and speed of the Internet connection. Also, you will have a better chance of getting SDSL service in your area because the distance required from your location to the provider is longer. Check Availability »
768 Kbps/ 768 Kbps SDSL SDSL (Synchronous Digital Subscriber Line) is a type of DSL circuit that provides the same download and upload speeds (hence the term "synchronous").

Features & Benefits

DSL Networking Options

  • Private IP addresses - IP addresses that are hidden from the public. Your business can access the Internet, but the public will not be able to see your computer or the rest of your business' computers, essentially keeping your network invisible, or private. (included)
  • up to 253 Public IP addresses - Public IP Addresses (also known as Static IP Addresses) are IP addresses that are visible to the public. Because they are public, they allow other people to know about and access your computer, like a Web server. In some cases, you do not want people to access your computer or you want to restrict certain individuals from accessing your computer or server. If that is the case, you will want to look into security measures to protect your computer. XO® offers several security solutions to help take the time and worry of maintain a secure computer, server and/or network. (optional)

DSL Equipment

You may supply your own router, assuming it is compatible with a Nokia or Lucent Stinger DSL Access Multiplexer (DSLAM). However, please take note that many off-the-shelf routers are not compatible.

Alternatively, Efficient Networks® 5851 routers can be made available to customers using both SDSL and IDSL circuits.
