DSL TECHNOLOGY (Digitial Subscriber Line Technology), in its various manifestations
(ADSL,SDSL,HDSL,AND VDSL), IS EXPECTED TO HAVE A DRAMATIC SOCIETAL IMPACT ON BOTH
OUR PERSONAL AND PROFESSIONAL LIVES.. STATED
SIMPLY, DSL PROVIDES HIGH-SPEED MULTIMEDIA SERVICES, SUCH AS VIDEO-ON-DEMAND,
SUPER-FAST INTERNET ACCESS, DISTANCE LEARNING AND VIDEO PHONING TO ANYONE WITH
A STANDARD, COPPER TELEPHONE LINE. BY PLACING DSL MODEMS AT BOTH A PHONE COMPANY'S
CENTRAL EXCHANGE OFFICE AND AT A CUSTOMER LOCATION, A TELCO CAN ENABLE ITS USERS
TO RECEIVE MULTIMEDIA CONTENT MORE THAN 400 TIMES FASTER THAN WITH TODAY'S
14,400 bps MODEMS, IT IS THE USE OF THE UBIQUITOUS COPPER NETWOEK THAT HAS CAUSED
DSL TO GAIN FAVOR AS A BETTER ALTERNATIVE TO ISDN AND CABLE MODEMS.. COMPARED
TO OTHER CURRENTLY AVAILABLE TECHOLOGIES, DSL MODEMS OFFER THE HIGHEST TRANSMISSION
RELIABILITY. THE FASTEST SPEEDS AND INTERACTIVE CAPABILITIES, FOR THE LEAST INVESTMENT.
DSL MODEMS AVAILABLE TODAY CAN DOWNLOAD THE ENTIRE ENCYCLOPEDIA BRITANNICA IN
31 MINUTES COMPARED TO 54 HOURS WITH A COMMON 14,400bps MODEM. |
| GENERALLY, WITH FOUR TYPES INCLUDED IN THE DSL FAMILY : (WE
COULD CALL IT ALL "XDSL" ) | | 1. ADSL - > | ADSL
DELIVERS SUPER-FAST RATE OF 32Kbps TO 8.192 Mbps DOWNSTREAM TO THE CUSTOMER AND
32Kbps TO 1.088Mbps UPSTREAM TO THE NETWORK WHILE SIMULTANEOUSLY PROVIDING PHONE
SERVICE ON THE SAME STANDARD PHONE LINE.
WITH ADSL, INTERACTIVE MULTIMEDIA
SERVICES CAN BE PROVIDED TO ALMOST ANYONE WITH A TELEPHONE LINE IN THEIR HOME
OR BUSINESS .. |
| 2. HDSL - > | THE
HIGH COST AND LENGTHY IMPLEMENTATION TIME OF TRADITIONAL T1/E1 AND FIBER LINES
HAVE BUSINESSES AROUND THE WORLD SCRAMBLING FOR MORE BANDWIDTH TO ACCOMMODATE
APPLICATIONS SUCH AS LAN INTERNETWORKING , VEDIO CONFERENCING AND PBX INTERCONNECT.
AS A RESULT, MORE AND MORE SERVICE PROVIDERS ARE DISCOVERING HIGH-BIT-RATE
TRANSPORT A FULL DUPLEX T1 (1.544Mbps) OR E1 (2.048Mbps) ACROSS EXISTING TWISTED
PAIR COPPER W/O REPERYERS. THIS HIGH-PERFORMANCE TECHNOLOGY IS THE QUICKEST AND
MOST COST-EFFECTIVE OPTION TO T1/E1 LINES ..AND PROVIDES A QUALITY TRANSMISSION
THAT IS COMPARABLE TO FIBER… |
| 3. SDSL - > | THIS
SDSL TECHNOLOGY PROVIDES SYMMETRIC (BI-DIRECTIONAL)HIGH SPEED, VARIABLE RATE COMMUNICATIONS.
SDSL ADDRESSES THOSE APPLICATION THAT REQUIRE A SYMMETRIC DATA RATE . SDSL DATA
RATE RANGE FROM 160Kbps TO 2.084Mbps.. |
| 4. VDSL - > | VDSL
TECHNOLOGY BOOSTS THE DATA RATES OF THE SUBSCRIBER LINE SIGNIFICANTLY. THE CLOSER
THE CUSTOMER IS TO THE CRETRAL EXCHANGE OFFICE, THE HIGHER THE DATA RATE. A SUBSCRUBER
AT A DISTANCE OF 5000FT AWAY FROM THE CENTRAL EXCHANGE OFFICE CAN GET A DATA RATE
OF 13Mbps AT 3000FT THAT SUBSCRIBER MAY ATTAIN DATA RATES UP TO 1026Mbps AND AT
1000FT, A 51 Mbps DATE RATE IS POSSIBLE… |
