DSL stands for Digital Subscriber line, it is technology where a DSL line is used to connect to the internet and transmit digital data through copper telephone lines. DSL is emerged as revolutionary and innovative technology solution in the 1980s and 1990s. In-depth discussion of DSL, Addressing connection, Types, Full form, and network topology is provided in this article.
DSL full form:
DSL stands for digital subscriber Line. This nomenclature is rooted in the technology fundamental function. The subscriber line is part of the name indicates that the technology is used on the individual lines of subscribers, typically ordinary telephone line that connect homes and business to the telephone company's central office.
There are three types of DSL:
- ADSL: With asymmetric DSL, download rates are quicker. Data reception is quicker than data transmission. 20 Mbps for downloads and 1.4 Mbps for uploads are possible.
- SDSL: Because symmetric DSL evenly divides the incoming and outgoing frequencies, the bitrates for uploads and downloads are equal.
- VDSL: Very high speed digital subscriber line, an upgrade on their prior HDSL, VDSL connects to extremely high frequencies providing download speed of up to 52 Mbps and upload speed of up to 16 Mbps. VDSL2 can provide speed up to 1000 Mbps for both upload and download.
How does DSL operates?
DSL transmit data by using copper telephone lines higher frequency channels. Because of this strategy, phone and internet services can operates simultaneously on the same line without interfacing with one another. A DSL modem, which modulates and demodulates data signals, and a DSL cable, which connects the modem to the phone line, are the essential part of a DSL connection. User will always have a dedicated line for internet access due to this configuration.
