Description

Digital Subscriber Line (DSL) technology, a new modem technology, converts existing
twisted-pair telephone lines into access paths for multimedia and high-speed data
communications. DSL technology transmits more than six MBPS to a subscriber, and as
much as 640 KBPS more in both directions. Such transmission rates expand existing
access capacity by a factor of 50 or more without new cabling. DSL technology can
literally transform the existing public information network from one limited to voice,
text, and low resolution graphics to a powerful, ubiquitous system capable of bringing
multimedia, including full-motion video, to everyone’s home this century.

How does it work?

DSL Internet technology converts existing twisted-pair telephone lines into access paths
for multimedia and high-speed data communications. ADSL Internet modems divide the
available bandwidth of a telephone line in one of two ways:
 Frequency-Division Multiplexing: Assigns one band for upstream data and another
    for downstream.
 Echo Cancellation: Assigns the upstream band to overlap the downstream, and uses
    local echo cancellation to separate the two. Other methods split off a 4 kHz region
    for POTS (Plain Old Telephone Service) at the DC end of the band.

What is an IP Address?

   Dynamic IP Address: This is an IP address that changes each time a user dials into
    the Internet (A hacker wouldn't necessarily know where the user is on the Internet
    because their IP address
    changes each time they dial in).
         Single User Product
         Single DSL session
         Speed: Down Up to 1500 (1.5M) / Up 128K
         Provides Features of dial-up product with high speed Dynamic IP
         Termination charge for disconnect prior to term: $200.00
         Online support 24 x 7
         Unlimited usage
   Static IP Address: This is an IP address that is permanently assigned to a customer.
    Each time the customer dials into the Internet, the customer is using the same IP
    address.
         Small Office or Home Office
         Designed for small LAN at home or small office
         Multiple User product
         Up to 125 Usable Static IP addresses
          Online support 24 x 7
          Termination charge for disconnect prior to term
          Online support 24 x 7
          Unlimited usage

SBC Yahoo! DSL customers will receive 8 static IP Addresses with their initial static
order for DSL service. Out of the initial 8 IP block assigned to the customer, 5 are
usable, 3 addresses are used for the following:

          Network
          Router (either the customer’s or SBCIS)
          Broadcast

What will DSL do for a customer?

DSL Internet makes remote access more efficient than ever with these key benefits:

   Data-over-voice capability. A customer can talk on the phone and use their data
    connection over one line.
   Increased Access Speed. A customer can transfer data up to twelve times faster than
    ISDN, 48 times faster than analog modems.
   Dedicated Connectivity. A customer is always connected; he will never get a busy
    signal or wait for dial-up.
   Efficiency. A customer needs only one pair of wires to transmit simultaneous voice,
    data, and video services
   Increased Security. A customer can enjoy the security of dedicated central office
     access and an ATM2 backbone.


Benefits


DSL Internet makes working from home more efficient than every before with these key
benefits:

   Data-over voice capability. A customer can talk on the phone and use their data
    connection on a single line.
   Increased access speed. DSL technology transfers data two to twelve times faster
    than
    ISDN and up to twelve to 48 times faster than analog modems. Higher transmission
    speeds mean the customer can download graphics and other large files at speeds
    comparable to a T-1 line (1.54 MBPS).
   Dedicated Connectivity. With DSL Internet, a customer is always connected to our
    central office. They will never get a busy signal or have to wait for dial-up. They
    simply click an icon for instant access to their ISP or company’s LAN.
