DSL is a modem technology that turns a customer's existing phone line into a three-channel data delivery system. One channel transmits voice services, so normal phone and fax usage continues whether or not you are accessing the Internet. A second channel transmits data downstream at high speeds, and a third bi-directional channel transmits data upstream. The downstream and upstream channels carry information to and from the Internet. Phone or fax calls occurring on the voice channel are not affected by your online activity occurring on the two data channels.
With WarpCore DSL Internet access, you have a fast connection to the Internet.
WarpCore DSL is designed to take advantage of the portion of the bandwidth not used for voice calls. WarpCore DSL technology splits your phone line into three information channels. One carries data at high speeds from the Internet to your home computer. Another channel transports data at moderate speeds from your home computer to the Internet. The third channel handles regular phone calls and faxes. You'll be able to surf the Internet while making phone calls or sending a fax. Your regular phone line will continue to work in the event that a power failure affects your computer.

2. How does WarpCore DSL work? WarpCore DSL is based on Asymmetric Digital Subscriber Line (ADSL), a super-fast modem technology that can provide data transmissions at significantly higher speeds than your standard 56K modem. WarpCore DSL transforms standard twisted-pair copper telephone wires into a high-speed digital pipe. Since this wiring is already inplace in most homes and offices, many of the users in our area can switch to WarpCore DSL service without the need to run new wires to your location.
The DSL modem maintains a digital link from your business to our network, driving ordinary telephone lines at speeds far beyond conventional dial-up modems. The DSL modem can be connected to your existing network (or directly to your PC using a special cable).
3. How fast is WarpCore DSL? WarpCore DSL offers several packages, starting with maximum connection speeds of up to 3.0MB downstream and up to 512K upstream. WarpCore DSL customers enjoy the ability to download files and surf the Internet at lightning speeds.
4. What solutions can WarpCore DSL provide growing businesses? WarpCore DSL provides customized solutions based upon your business needs, including:
- Dependable high-speed Internet access at affordable rates
- Full Internet connectivity
- Enhanced e-mail
- Web hosting
- Firewall protection
- Online backup
- Remote Dialup
- Video conferencing
5. Can WarpCore DSL services neet the growing needs of my company? Yes. As your company grows and you need more and/or faster connections, WarpCore DSL can provide bandwidth up to 3.0 Mbps at very reasonable prices. Furthermore, WarpCore DSL continually offers additional enhanced services to meet your growing needs. Unlike dial-up connections, WarpCore DSL service enables adding an unlimited number of users to your DSL line.
6. Can anyone have DSL services? No. DSL technology is a distance-sensitive service. To determine if your business is within the WarpCore DSL area, please call our WarpCore DSL sales representative at: 1-866-323-9500.
7. Can I keep my domain name and e-mail account when I convert to WarpCore DSL service? Yes. Your domain name can be easily transferred and you can keep your e-mail account.
8. Are Warpcore DSL customers able to use their telephone or fax machine while accessing the Internet over WarpCore DSL? Yes. WarpCore DSL allows customers to use their existing phone line for voice communications or faxing while they use WarpCore DSL service for Internet access or data communication services.
9. Does WarpCore DSL require installing an additional phone line? No. WarpCore DSL technology utilizes varying frequency spectrums for data transmission. This allows simultaneous analog voice or fax and WarpCore DSL data transmission over the same telephone line. You still use your phone as you do now.
10. How does WarpCore DSL support both voice and data on the same line? A device called a "splitter" assigns voice and data transmissions to different frequencies. Digital bits travel on the inaudible frequencies of your phone line. That keeps them separate, and that's why all the signals - voice and data - can work in parellel without colliding with each other. A WarpCore DSL modem spreads signals over many frequencies on the line, carrying many times more information than an analog dial-up modem.
11. Will my telephone work even if my computer or modem is unplugged or disabled? Yes. DSL modems have been designed so that your normal telephone service will operate even if the computer or DSL modem is unplugged or otherwise disabled.
12. Can I hook up more than one computer? Yes, but the bandwidth will be shared among all of the active connections. Also, WarpCore DSL does not provide technical support for networks. If you choose to set up a network, you need to have the appropriate network systems in place.
13. Am I charged for the time my DSL modem or computer is online? No. WarpCore DSL Internet access is unlimited. You will not have to worry about how long your modem or computer is in use or turned on.
14. Will my current phone features work with DSL? Yes. WarpCore DSL won't affect Caller ID, Voice Mail, Call Waiting or other advanced calling features. However, Distinctive Ring may not work with WarpCore DSL in some areas.
15. Can I connect to AOL content? Yes, America Online offers a special TCP/IP account for customers who already have high-speed internet access (ISDN, DSL, etc.). This allows you to use your WarpCore DSL service to access AOL content.
16. How much does WarpCore DSL cost? Plans start as low as $49.99
17. Do I need to sign a contract? A minimum one year service agreement is required.
18. Are WarpCore DSL charges in addition to my current monthly phone bill charges? Yes. WarpCore DSL monthly recurring charges are in addition to your monthly telephone service charges from Sprint.
19. What equipment do I need for DSL access? A DSL end-user must be equipped with a DSL modem, Ethernet card and a computer. The DSL modem must be compatible with our WarpCore DSL equipment and can be ordered from WarpCore DSL. In addition, the end-user's computer must meet recommended minimum system requirements.
20. How is the service installed? WarpCore DSL makes the DSL installation easy.
- We order the new line from your local telephone company.
- Once that line has been installed, we arrange for the inside wiring within the office location.
- We install the DSL modem and perform a 24-hour test to establish an error-free link.
- We assign IP numbers and provide configuration information to you or your IT vendor.
Your IT personnel or vendor configures each work station and your high-speed access to the Internet is now ready for use!
21. Can I use any DSL modem with my WarpCore DSL service? No, at this time you need to use a modem that is compatible with WarpCore DSL. If you want to use a modem from another source, please check with us first to determine compatibility.
22. How is DSL different from other Internet connections?
Dial-up (Analog)
Modems
Analog modems were designed
to work on regular telephone lines and usually operate at speeds ranging
from 28.8K to 56K. The main difference between analog and DSL modems is
that an analog modem works over voice frequencies. It can't handle the
higher - and much faster - digital frequencies. DSL actually takes a load
off the voice channels by using the higher, non-voice frequencies.
Cable Modems
Some Internet connections
are available through cable television lines that have been upgraded to
carry data in two directions. However, you share bandwidth and this access
with your neighborhood, so there is a possibility of slowdowns during
peak-use periods just because your neighbors log on.
DSL
DSL technology provides a
dedicated service over an existing local connection to the WarpCore DSL
central office near you. This means that you don't have to share your
local access connection with other users.
23. When does scheduled maintenance occur on the WarpCore DSL network? In order to minimize service interruptions as much as possible, scheduled maintenance on the WarpCore DSL network is typically performed between 1am and 4am ET on Wednesdays, and between 1am and 5am ET on Sundays (although WarpCore DSL reserves the right to alter this schedule at its discretion).
24. What happens
if I drop my connection or have service problems? DSL technology is
similar to a Local Area Network (LAN), therefore, you will not experience
the same dropped connections as you may with a dial-up modem. In addition,
we are constantly monitoring our network to assure optimum service. However,
in the unusual event that you do experience difficulties, WarpCore DSL
offers a customer service department with trained professionals available
to assist you 24 hours per day, 365 days a year. Customer service can
be reached at 1-866-323-9500.
