A new piece of data communications equipment terminates the IDSL connection and shunts it off to a router or data switch. This is a key feature because the overloading of central office voice switches by data users is a growing problem for telcos. The limitation of IDSL is that the customer no longer has access to ISDN signaling or voice services.
The American National Standards Institute (ANSI) Telecommunications Committee created the first standardized ADSL specifications. They were published as ANSI T1.413-1995 and ANSI T1.413-1998 (sometimes called "issue 2") titled Network and Customer Installation Interfaces — Asymmetric Digital Subscriber Line (ADSL) Metallic Interface.
This is a list of very-high-bit-rate digital subscriber line (VDSL) and very-high-bit-rate digital subscriber line 2 (VDSL2) deployments.. The term VDSL can either refer specifically to ITU-T G.993.1 (first generation VDSL, officially abbreviated as "VDSL", unofficially also called "VDSL1"), or may be used as an umbrella term for both ITU-T G.993.1 and ITU-T G.993.2 (second generation VDSL ...

IDSL is a four letter acronym that can stand for: International Day of Sign Languages; ISDN digital subscriber line; ID-SL, ISO 3166 code for Sulawesi
Although the term had a meaning in physics and engineering (similar to wideband), the CCITT defined it as: "Qualifying a service or system requiring transmission channels capable of supporting rates greater than the primary rate" [2] referring to the primary rate which ranged from about 1.5 to 2 Mbit/s. Services envisioned included video ...
VDSL2 is an enhancement to VDSL designed to support the wide deployment of triple play services such as voice, video, data and high-definition television (HDTV) VDSL2 is intended to enable operators and carriers to gradually, flexibly, and cost-efficiently upgrade existing xDSL infrastructure.
The farther away from the switching center the modem is, the longer the telephone wires, the weaker the signal, and the lower the data rate that the modem can achieve. Users in cities, close to switching centers, may have access to higher rate service, up to 24 Mbit/s. [2] The distance limit for ADSL is 18 000 feet (5.5 km or 3.4 miles). [2]
