analog Economical but slow Also called dial-up access Typical Dial-up connection speeds range from 2400 bps to 56 Kbps.
Integrated services digital network transfer videos, music, data's, graphic and other source materials. Use normal telephone wire Typical ISDN speeds range from 64 Kbps to 128 Kbps. ISDN
B-ISDN Fiber optical SONET
DSL Also called ALWAYS ON CONNECTION DSL and SDSL
Set up for DSL
ADSL asynchronous DSL support data rate from 1.5 to 9 Mbps while receiving and 16 to 640 Kbps on sanding datas. Special ADSL modem required
SDSL s synchronous DSL supports data upto 3 Mbps commonly used in Europe
VDSL Very high DSL. covers a short distance. All DSL technology are usually called xDSL. xDSL connection speed range from 128 kbps to 8 Mbps.
CABLE Cable modem. oaxial cable. Speed range from 112 Kbps to 20 MBPS
WIRELESS Also called Broadband connection. Relatively new Always on Expensive
How Wireless works
T-1 LINE Popular least line. used for business purposes. fractional T-1 access speed around 1.544 Mbps
BONDED T-1 Two or more T-1 line Must run to same ISP Speed around 3 Mbp s
T-3 LINE Data rate of 43 to 45 Mbps Also a popular leased line 672 individual channels used by ISP
SATELLITE Geostationary Placed at a static point. IOS is Bit slower
