Data networks
design and planning by Spartan Contracts

Our design service will provide a detailed design report and site survey that includes the following: 

• The resources required
• The associated cost
• Diagrammatic plans
• Time frames
• Testing techniques
• TCP/IP addressing schemes (if required)

We believe that installation / extensions to cabling systems are best approached from a holistic viewpoint as this ensures trouble free installations and maintains high speed performance, which results in years of trouble-free service.

A typical application

(Employing direct patching from HUB to distribution field)

Generic cabling

Today's market direction is in multipurpose, generic cabling systems, designed to support virtually any building communication needs.

Example systems include:-

• AT&T PDS/Systimax
• IBM ACS/ICS
• Northern Telecoms BCS
• Bull CS
• DEC Connect Open Link / Open Connect
• MOD TAP systems

Generic cabling standards were developed to meet this growth in order to:

• Give guidance on planning and design
• Provide specific component and cabling specifications

Future applications are specified to run on generic schemes:

• E.G. 155MBps ATM runs over 'Category 5'
• The first generic standard

Structured cabling

Structured Cabling is defined as building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called sub-systems.

Structured cabling falls into the following six sub-systems:

• Entrance facilities - where the building interfaces with the outside world
• Equipment rooms - host equipment which serves the users inside the building
• Telecommunications rooms - where various telecommunications and data equipment resides, connecting the backbone and horizontal cabling sub-systems
• Backbone cabling - carries the signals between the entrance facilities, equipment rooms and telecommunications rooms
• Horizontal cabling - the wiring from telecommunications rooms to the individual outlets on the floor
• Work-area components - connects end-user equipment to the outlets of the horizontal cabling system

Structured cabling installations are not vendor specific or topology dependent. They have several benefitting features:

• Flexible
• Facilitates easy changes and moves
• Low cost of change
• Building asset
• Investment protection - long life span
