 | | The name ADSL Lite is sometimes used for the slower versions. | | | However, this requires matching vendor-supplied equipment on both ends of the line, and will likely result in crosstalk issues that affect other lines in the same bundle. | | | On the technical side, there is likely to be more crosstalk from other circuits at the DSLAM end (where the wires from many local loops are close together) than at the customer premises. |

| | Digital Subscriber Line - Wikipedia, the free encyclopedia |
| | All flavors of DSL employ highly complex digital signal processing algorithms to overcome the inherent limitations of the existing twisted pair wires. | | | The standard way to let multiple computers share a DSL connection is to use a router that establishes a connection between the DSL modem and a local Ethernet or Wi-Fi network on the customer's premises. | | | Each channel is evaluated for usability in much the same way an analog modem would on a POTS connection. |

| | Digital Subscriber Line is a technology that assumes digital data does not require change into analog form and back. | | | G.lite (also known as DSL Lite, splitterless ADSL, and Universal ADSL) is essentially a slower ADSL that doesn't require splitting of the line at the user end but manages to split it for the user remotely at the telephone company. | | | That's why your computer has to have a modem - so that it can demodulate the analog signal and turn its values into the string of 0 and 1 values that is called digital information. |

| | Digital Subscriber Line (DSL) |
| | ADSL depends on advanced digital signal processing and creative algorithms to squeeze so much information through twisted-pair telephone lines. | | | An ADSL modem organizes the aggregate data stream created by multiplexing downstream channels, duplex channels, and maintenance channels together into blocks, and attaches an error correction code to each block. | | | VDSL technology resembles ADSL to a large degree, although ADSL must face much larger dynamic ranges and is considerably more complex as a result. |

| | Delivering ADSL to DLC—fed end-users is a difficult challenge to meet because ADSL does not work with DLC systems without some sort of infrastructure upgrade. | | | This tutorial provides a brief background of the challenge of delivering ADSL to DLC–fed end users, as well as a number of ways this challenge is being addressed. | | | Asymmetric digital subscriber line (ADSL) technology is used to transport large amounts of data traffic over existing copper telephone lines—up to 8 Mbps downstream and 640 kbps upstream—while simultaneously supporting plain old telephone service (POTS). |
