A passive cabling system is a complete system of cabling and associated
hardware, which provides a comprehensive telecommunications infrastructure.
This infrastructure serves a wide range of uses, such as to provide telephone
service or transmit data through a computer network.
It should not be device dependent.
We further define a structured cabling system in terms of ownership.
The structured cabling system begins at the point where the service
provider (SP) terminates. This point is 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.
The methods we use to complete and maintain cabling installations are
relatively standard. The standardization of these installations is necessary
because of the need to ensure acceptable system performance from
increasingly complex arrangements.
The benefits of our standards include:
– Consistency of design and installation.
– Conformance to physical and transmission line requirements.
– A basis for examining a proposed system expansion and other changes.
