Overview

An SCS is defined as the complete collective configuration of cabling and associated hardware at a given site that has been installed to provide a comprehensive telecommunications infrastructure. This infrastructure is intended to serve a wide range of usage, such as to provide access to telephone service or computer networks, and should not be device or application dependent.

In this manual, an SCS is further defined in terms of ownership. The SCS begins at the point at which the service provider (SP) terminates. This point is also known as the point of demarcation (demarc) or network interface device (NID).

For example, in a telephone system installation, the SP furnishes one or more service lines (per customer requirements). The SP connects the service lines at the point of demarcation.

Every structured cabling system is unique. This is due to variations in:

• The architectural structure of the building that houses the telecommunications cabling installation.

• Cable and connecting hardware.

• The function of the cabling installation.

• The types and characteristics of equipment that the cabling installation will support, both present and future.

• The configuration of an existing cabling installation (in the cases of upgrades and retrofits).

• Customer requirements.

• Warranties offered by manufacturers.
