SERVICES: INTERNET CONNECTIVITY
|
Internet Connectivity
This group of services is focused around providing users’ access to the Internet.
An Internet Access Provider has the equipment and the telecommunication line access
required to have Access point on the Internet for the geographic area served.
Application e.g.: Dealers with applications or procedures requiring access to any
Internet sites, or web based services such as FTP, E-MAIL, IP-VPN.
Types (Speeds/Flavors)
• T1(dedicated access); 64Kbps - 1.544Mbps
The T1 (or T-1) carrier is the most commonly used digital line in the United States,
Canada, and Japan. In these countries, it carries at an overall rate of 1.544 million
bits per second (Mbps). T1 carrier is dedicated service, dealers that may require High
speeds, added security, application/web hosting, reliability/guaranteed uptime, and high
speed access would find a T1 as the only prudent option.
•DSL (S); 192Kbps - 1544Kbps
SDSL (Symmetric Digital Subscriber Line) is a technology
for transmitting digital information at a high bandwidth on existing phone lines to homes
and businesses. Unlike regular dialup phone service, SDSL provides continuously-available,
"always on" connection. SDSL is symmetric in that it transmits at the same rate downstream
as up.
•DSL (I) 144Kbps
IDSL is a system in which digital data is transmitted at 128
Kbps on a regular copper telephone line from a user to a destination using digital (rather
than analog or voice) transmission, bypassing the telephone company's central office equipment
that handles analog signals. IDSL uses the Integrated Services Digital Network (ISDN).
*ISDN passes through the phone company's central office voice
network; IDSL bypasses it by plugging into a special router at the phone company end
*ISDN requires call setup; IDSL is a dedicated service
*ISDN may involve per-call fees; IDSL may be billed at a flat
rate with no usage charges.
•ISDN 64Kbps - 128Kbps; (not recomended by Ford)
ISDN, which stands for Integrated Services Digital Network,
is a system of digital phone connections, which has been available for over a decade. With
ISDN, voice and data are carried by bearer channels (B channels) occupying a bandwidth of 64
Kbps (bits per second) 2 Channels achieve 128Kbps.
•DSL (A); (*shared)128Kbps - 1544Kbps; (not recomended by Ford)
ADSL (Asymmetric Digital Subscriber Line) is a technology for
transmitting digital information at a high bandwidth on existing phone lines to homes and
businesses. Unlike regular dialup phone service, ADSL provides continuously-available, "always
on" connection. ADSL is asymmetric in that it uses most of the channel to transmit downstream
to the user and only a small part to receive information from the user. ADSL simultaneously
accommodates analog (voice) information on the same line. This service has limited service
areas and is generally not sold to Business.
•Cable Modem; (*shared)128Kbps - 1544Kbps;
A cable modem is a device that enables you to hook up your PC to a local cable TV line and
receive data at about 1.5 Mbps. This data rate far exceeds that of the prevalent 28.8 and
56 Kbps telephone modems and the up to 128 Kbps of Integrated Services Digital Network
(ISDN) and is about the data rate available to subscribers of Digital Subscriber Line (DSL)
telephone service. A cable modem can be added to or integrated with a set-top box that provides
your TV set with channels for Internet access. In most cases, cable modems are furnished as
part of the cable access service and are not purchased directly and installed by the subscriber.
•56Kbps Dial; (*shared)56Kbps; (not Acceptable by Ford)
Dial-up pertains to a telephone connection in a system of many
lines shared by many users. A dial-up connection is established and maintained for a limited
time duration. The alternative is a dedicated connection, which is continuously in place.
