Structured cabling design and installation is governed by a set of standards that
specify wiring data centers, offices, and apartment buildings for data or voice
communications, using category 5 (CAT 5E) or category 6 cable (CAT 6) and modular
sockets. These standards define how to lay the cabling in a star formation, such
that all outlets terminate at a central patch panel (which is normally 19 inch rack-mounted),
from where it can be determined exactly how these connections will be used. Each outlet
can be 'patched' into a data network switch (normally also rack mounted alongside), or
patched into a 'telecoms patch panel' which forms a bridge into a private branch
exchange (PBX) telephone system, thus making the connection a voice port.
Lines patched as data ports into a network switch require simple straight-through patch
cables at the other end to connect a computer.
An IP (Internet Protocol) PBX (Private branch exchange) is a business telephone system designed
to deliver voice or video over a data network and interoperate with the normal Public Switched
Telephone Network (PSTN).
VoIP (Voice over Internet Protocol) gateways can be combined with traditional PBX functionality
enabling businesses to use their managed intranet to help reduce long distance expenses, enjoy
the benefits of a single network for voice and data and advanced CTI features or be used on a
pure IP system which in most cases give greater cost savings, greater mobility, and increased
An IP-PBX can exist as a hardware object, or virtually, as a software system.
Wireless network refers to any type of computer network that is wireless, and is commonly associated
with a telecommunications network whose interconnections between nodes is implemented without the use of wires.
Wireless Local Area Network (WLAN) is a wireless alternative to a computer Local Area Network (LAN) that uses
radio instead of wires to transmit data back and forth between computers in a small area such as a home,
office, or school. Wireless LANs are standardized under the IEEE 802.11 series.
WiMAX, meaning Worldwide Interoperability for Microwave Access, is a telecommunications technology that provides
wireless transmission of data using a variety of transmission modes, from point-to-multipoint links to portable and
fully mobile internet access. The technology provides up to 3 Mbit/s broadband speed without the need for cables.
