A line card or digital line card is a modular electronic circuit designed to fit on a separate printed circuit board (PCB) and interface with a telecommunications access network. [1] A line card typically interfaces with a twisted pair cable of a plain old telephone service (POTS) local loop to the public switched telephone network (PSTN).
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access .
Uni-DSL (UDSL) in telecommunications is a digital subscriber line (DSL) marketing buzzword developed by Texas Instruments which would provide bit rates of at least 200 Mbit/s in aggregate on the downstream and upstream paths. [1] UDSL is backwards compatible with all discrete multitone modulation (DMT) standards (ADSL, ADSL2, ADSL2+, VDSL and ...

With the growth in popularity of digital subscriber line (DSL) and the benefits provided by shorter metallic loops used with DLC systems, digital loop carriers are sometimes integrated with digital subscriber line access multiplexers (DSLAM), both systems then taking advantage of the digital transmission link from the DLC to the CO.

Very high-speed digital subscriber line (VDSL) [1] and very high-speed digital subscriber line 2 (VDSL2) [2] are digital subscriber line (DSL) technologies providing data transmission faster than the earlier standards of asymmetric digital subscriber line (ADSL) G.992.1, G.992.3 (ADSL2) and G.992.5 (ADSL2+).
Single-pair high-speed digital subscriber line (SHDSL) is a form of symmetric digital subscriber line (SDSL), a data communications technology for equal transmit and receive (i.e. symmetric) data rate over copper telephone lines, faster than a conventional voiceband modem can provide.
