subject: A Quick History Discussing Fibre Optic Broadband Solutions [print this page] Medium and large organizations and small organizations whose servers are frequently visited Web sites should focus on solutions with higher bandwidth, such as fibre optic broadband. T-1 is a high-capacity cable line for data transmission at a speed of 1.544 Mbps. A T-1 leased line connection is one that organizations typically use to connect their own network to the Internet or to another town located outside their local network. Smaller ISPs may, by connection type T-1 connect many of their subscribers to the Internet.
At full speed, a T-1 line ought to theoretically transfer an entire 1 megabyte in a time of around 10 seconds. Organizations that require a channel with bigger transmission intensity, there's an alternative choice. Use a T-3 connection, which is usually recommended in high speed cases.
T-3 is a leased line fibre broadband connection capable of transmitting data at 44,736,000 bits per second. What type of Internet connection you choose depends on your assessment of the relationship between connection speed and cost. Leased lines with high throughput are likely to prove too expensive for individuals and smaller companies.
This doesn't have to mean you can't acquire satisfactory access to the net at an affordable cost. A superb choice for people and smaller businesses are analog lines, as well as ISDN lines, which are less costly.
ISDN is a standard for digital transmission services for telephony and data for use in homes and businesses. ISDN allows transfer on one conductor or optical fiber for human voice, data and digital video. Unless superseded by a yet unknown technology, ISDN replaces the old (analog) telephone system.
ISDN is employed largely for automatic exchanges. They receive higher speeds, when compared to standard analog connections. These lines offer 3 basic forms.
The options are PRI, BRI and B-ISDN. Individual customers use BRI, as it offers 2 channels with a speed of sixty four thousand bits per second. On he other hand, PRI provides twenty three such channels. B-ISDN happens to be a newer technology that's able to give you transmission speeds of up to a hundred and fifty million bits every second . This is a realistic 150 mbps (mega bits per second).
ISDN lines are often utilized in major cities, being offered by many ISPs. They are often used to help individual and small LAN networks to connect to the net. To use ISDN, you need to get an ISDN-adapter that can work on your PC. If you us a LAN - you must use some sort of ISDN-router.
In medium size and bigger corporations, there is the need and the resources required to determine a move to higher permeability lines. As a matter of fact, when connecting a company network with many users to the net, in pure terms of value, it's wiser and more economical to make use of leased lines, that offer high permeability. This is more often than not better than to be connected via a modem and an ISDN or analogue line.
As a user you can choose between several types of Internet connection. These are all characterized by different productivity. The best option for fastest speeds is fibre optic broadband.
