optical fiber, and may be installed within or between buildings.
Premises wiring may consist of horizontal wiring, vertical wiring, and backbone cabling. It may extend from the point-of-entry to

Ownership
The ownership of on-premises wiring varies between jurisdictions: It depends on the location of the
demarcation point. The location determines ownership and responsibility for maintenance and repair.
In the United States and Canada, most premises wiring is owned by the customer. There generally is a demarcation point "as close to the poles" as possible. For many installations, this is a
network interface device mounted on the outside of the building. In some cases, it is a minimum-point-of-entry (MPOE) location inside the building.
In the United Kingdom, the demarcation point is the wall jack, and hence most of the on-premises wiring is the property of the
telephone company.
