Structured Cabling

TW Data Limited's core business service revolves around Structured Cabling systems.

Structured Cabling Systems provide an expandable and flexible platform for a business' information system, totally independant, they are the life blood of a building's infrastructure.

Structured cabling is building or campus telecommunications cabling infrastructure that consists of a number of standardised smaller elements (hence structured) called subsystems.

Structured cabling falls into six subsystems:

  1. Entrance Facilities are where the building interfaces with the outside world.
  2. Equipment Rooms host equipment which serve the users inside the building.
  3. Telecommunications Rooms house telecommunication equipment which connect the backbone and the horizontal cabling subsystems.
  4. Backbone Cabling connect between the entrance facilities, equipment rooms and telecommunications rooms.
  5. Horizontal Cabling connect telecommunications rooms to individual outlets on the floor.
  6. Work-Area Components connect end-user equipment to outlets of the horizontal cabling system.

Structured cabling design and installation is governed by a set of standards that specify wiring data centres, offices, and apartment buildings for data or voice communications, using category 5e (CAT 5e) or category 6 cable (CAT 6 & 6A) and modular sockets. These standards define how to install the cabling in a star formation, such that all outlets terminate at a centralised patch panel, from where it can be determined exactly how these connections will be used.

Each outlet can be 'patched' into a data network switch, or patched into a 'telecoms patch panel' which forms a bridge into a private branch exchange (PBX) telephone system or VoIP Switch (Voice over IP), 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. Voice patches to PBXs in most countries require an adapter at the remote end to translate the configuration on 8P8C modular connectors into the local standard telephone wall socket.

It is common to color code patch panel cables to identify the type of connection, though structured cabling standards do not require it, except in the demarcation field.

Cabling standards demand that all eight connectors in Cat5e/6/6A & 7 cables are connected, resisting the temptation to 'double-up' or use one cable for both voice and data. This is generally helpful as it means that they fully support features such as Power over Ethernet.

TW Data limited ensure that all installed cabling follow the UK Standards which are Govened by the following bodies:

  • ISO
  • BSEN
  • IEEE

This does again follow strict installation practices from SoHo (Small office Home Office) installations through to very large corporate buildings, education and commercial warehousing. TW Data have the expertise and experience in all of these areas.
