heist. This is a high speed connection, with
speeds ranging from four megabits up to 250 megabits. Is the normals package speeds that you'll see with cable Internet service. Now there are gigabits speeds that are available as well.
D S. L. D s L is another Internet service that we have talked about previous lessons that you may be familiar with D S. L is asymmetrical digital subscriber line in the true name is a D A sale.
It's a competitive to cable on. It uses phone lines as his connection. Medium
on the download is faster than the upload. That's what asymmetrical means. Distance limitation is between 8000 to 30,000 feet from the phone company Search, Central office or the CEO so that pose some limitations in certain geographical locations, depending on how close you are to the central office.
Speeds of up to 50 52 megabits with a download and an upload speed of 16 megabits and again speeds will vary depending on your location. Another Internet service that you don't see that much of nowadays is dial up
dialogue works on Anna analog phone lines and its speed limitations or speed ceiling. Rather
was 56 kilobits a second, and that today that seems very, very slow. But back when that was the primary connection, it was very useful at that time. No broadband, very slow connection compared to species nowadays. Traditionally, you would use these for Internet connection.
They would awful be used for
connections with industrial equipment and hardware. Nowadays, they still are used in some businesses as a backup system. When Internet connection goes down, a modem would be used to connect locations together for various reasons or passing information.

There are two types of eyes. Deion's, the B R I and the pure eyes.
Basic Ray interface. Or, to be plus D to 64. Kill a bit bearer be channels and 1 16 bit signaling D channel in the B r. I

Other flavors of line of sight Internet consists of wireless Internet service providers are whisp, and they provide Internet service over the frequencies off 2.4 gigahertz as what? It's five gigahertz.
All right, So today's lesson. We talked about different Internet connection types. And again, these are different Internet connection types that you need to know for the county A plus and, as again in the real world, as a technician helping a customer decide what type of Internet connection, maybe their best option.
