At the wall jack where the DSL modem is installed, a commercial 2-line splitter adapter is used that puts each line of the cable on its own jack port, connected as Line 1. The telephone, if any, is plugged into the Line 1 jack and the DSL modem is plugged into the Line 2 jack of the adapter, but is fed through the Line 1 contacts in that jack ...
In regular DSL, a cable runs from the telephone switch to a piece of equipment called a Plain Old Telephone Service (POTS) splitter. This splitter separates the DSL and voice bands. Thus the customer will have a dial tone, which allows them to use the telephone line as a regular land line while they are using it to access the Internet on their ...
Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.
One line passes through a DSL filter before going to the old demarc, and from there to the remainder of the house. In telephony , the demarcation point is the point at which the public switched telephone network ends and connects with the customer's on-premises wiring .

Two simple NIDs, carrying six lines each, on the outside of a building A German copper phone line termination box called Abschlusspunkt LinienTechnik (APL, "Demarcation point") In telecommunications , a network interface device ( NID ; also known by several other names) is a device that serves as the demarcation point between the carrier's ...
Four-conductor shielded cable with metal foil shield and drain wire. Coaxial cable. Electronic symbol for a shielded wire. A shielded cable or screened cable is an electrical cable that has a common conductive layer around its conductors for electromagnetic shielding. [1] This shield is usually covered by an outermost layer of the cable.
The network isolator is a passive device, and functions without any requirement of an external power supply. A functional equivalent to network isolators is Ethernet over a small stretch of optical fibre , using media converters or Ethernet switches/network cards with fiber connections on each end.
