What is the history of DSL?
Lechleider, known as one of the fathers of DSL, became part of Bell Labs in 1955. But it was not until the early 1980’s that he proposed to unevenly allocate bandwidth between download and upload speeds. Now known as Asymmetrical DSL, the new technology significantly eliminated electrical interference in copper lines.
When was DSL first available?
In the early 1990s the first variety of DSL, high-bitrate DSL (HDSL), was rolled out with the intent of being used for on-demand television.

When did people stop using DSL?
On October 1, 2020, AT in the USA announced the formal end of DSL. AT will stop selling digital-subscriber-line connections, stranding many existing subscribers on those low-speed links and leaving new residents of DSL-only areas without any wired broadband.
What is DSL technology?
A technology for high-speed network or Internet access over voice lines. There are various types, including asymmetric DSL (ADSL), high-bit-rate DSL (HDSL), symmetric DSL (SDSL) and very-high-bit-rate DSL (VDSL). The whole group is sometimes referred to as “xDSL.”
Is DSL still used?
Wide availability—DSL is incredibly widespread within the US. Almost 90% of the US population has access to a DSL network, including over 70% of people living in rural areas. In many areas, DSL is the only form of wired internet available.
What are some of the DSL technologies?
Types of DSL Technologies
- RADSL – (Rate Adaptive Digital Subscriber Line)
- ADSL – Asymmetrical Digital Subscriber Line.
- ADSL Lite (or G.lite)
- R-ADSL – Rate-Adapative Digital Subscriber Line.
- HDSL – Hight Bit-Rate Digital Subscriber Line.
- IDSL – ISDN Digital Subscriber Line.
- SDSL – Symmetric Digital Subscriber Line.
What is replacing DSL?
Fiber-to-the-home is the fastest option for both download and upload speeds. The other two categories rely on old copper phone lines and are both technically DSL offerings, but they differ in how close the homes are to AT’s fiber network.
What will replace DSL?
No more DSL for new customers Fiber-to-the-home is the fastest option for both download and upload speeds. The other two categories rely on old copper phone lines and are both technically DSL offerings, but they differ in how close the homes are to AT’s fiber network.
What is the latest DSL technology?
VDSL. VDSL (Very high data rate DSL) is a developing technology that promises much higher data rates over relatively short distances (between 51 and 55 Mbps over lines up to 1,000 feet or 300 meters in length). It’s envisioned that VDSL may emerge somewhat after ADSL is widely deployed and co-exist with it.
