The IBDN structured cabling systems have the following features:
Structured Cabling - a strategic component of the network. Information has become a strategic resource that needs to flow quickly and accurately. That is why information networks have become critically important to business. What is not generally known, however is how important cabling is to an information network.
Cabling typically accounts for the smallest percentage of a network investment, yet when done improperly, cabling can be the cause of many network problems. Additionally, more stress will be placed on the cabling system as new applications such as Multimedia and Full Motion Video demand an increase in data transmission speeds. Cabling is strategic and important to the smooth operation of the network, both now and in future. Now is the time to be thinking about utilizing the benefits of structured cabling in the business.

Structured cabling is a standards based method of engineering and installing an integrated data, voice and video cabling system for your business. A properly designed and installed structured cabling system provides you with a cabling infrastructure that delivers predictable performance as well as flexibility to accommodate growth and change over an extended period of time. Additionally, a structured cabling system provides a uniform, open physical cabling topology that can simultaneously support multiple logical networking topologies for different applications such as Ethernet, token-ring, ATM or video.
Your initial investment in a 'standards' based structured cabling system will return many benefits including an extended operational lifespan, predictable performance, manageability and growth. These benefits bring increased efficiency, improved productivity and reduced costs to you and your business.
Structured cabling is defined by ISO/IEC, TIA/EIA and CSA standards.
Domestic and international standards organizations have been formed to ensure that manufactured products meet certain quality, safety and performance 'norms' for that category and class of product. Standards organizations such as ISO/IEC, TIA/EIA, CENELEC and CSA have created and published standards for structured cabling components and systems, and their specifications for Category 5 structured cabling systems are widely used and accepted in the industry today.
Category 5 specifications were developed to define the use of low cost Unshielded Twisted Pair (UTP) cabling and components in a structured cabling system with design parameters specified up to 100MHz. Category 5 related specifications continue to be refined by the various standards organizations, and Category 5 specifications will continue to be the benchmark for basic structured cabling systems for the foreseeable future.
The constant need for faster and more efficient network applications will, inevitably, result in the need for higher performance structured cabling systems. Standards organizations around the world are already working on developing new standards to define enhanced performance parameters beyond the current scope of Category 5 specifications.
For end-users, the challenge will be in selecting a structured cabling system that meets their current and future needs. If those needs dictate the implementation of a system with performance capabilities beyond the current Category 5 specifications, end-users should look to a manufacturer with a proven track record in the area of standards compliance who is prepared to offer systems with performance guarantees beyond the minimums currently defined for Category 5 systems.
Some people are under the impression that planning for the future requires only the specification of Category 5 components. Unfortunately, it is not that simple.
Category 5 is the hottest of industry buzzwords and is intended to provide connectivity using low cost Unshielded Twisted Pair (UTP) components with design parameters specified up to 100 MHz. A properly designed and installed Category 5 network should meet your networking needs into the foreseeable future. That's the good news, but what defines the right system?
Standards compliant does not mean performance assured. This is true for many reasons:
Three things are required for a system to work properly both today and in the future.
Quality of Components - to have quality components that have been tested and proven to be able to provide a Category 5 system when they are connected together. It provids a complete range of cabling components all of which are of superior quality and design and all of which have been tested as a system.
Quality of Design - to have a design that is capable of maintaining its administrative ease and flexibility over the lifetime of the system. Many of the rules and concepts only now being introduced in the industry were originally specified in the IBDN guidelines.
Quality of Installation - to ensure the cabling system is properly installed. IBDN systems are installed by CSVs and FACs who have been properly trained and qualified in the installation of IBDN cabling systems.
IBDN is end-to-end structured cabling system. As a system, IBDN offers the assurance of Certification which goes beyond Category 5 compliance to assure network performance. Certification means lifetime application assurance which includes not only the applications of today but applications of the future such as 100Base-T Ethernet and 155 Mbps ATM.

Gigabit networking has arrived. As the pace of business will only get faster. Email, the internet, intranets, video conferencing and so on will all contribute to the development of high-throughput networking hardware.
IBDN provides application independence, multiple logical topologies and easy moves, adds and changes. In other words, installing IBDN allows you to build an information infrastructure that will evolve with the changes in your organization, as well as the changes in technology, to constantly keep your work environment competitive.
Leading edge companies have come to realize that effective communication is their most valuable weapon in business. An information network that delivers the services required in a reliable, efficient manner is what the work force is demanding.
IBDN Gigabit Cabling Solutions are designed to meet the varying needs of different enterprises. Evolved from our field-proven Category 5 IBDN Structured Cabling System, the new IBDN Gigabit Cabling Solutions allow you to design and implement a network to suit your particular needs. With two performance options - IBDN System 1200 and System 2400 - IBDN now offers a choice of engineered solutions for the gigabit era.
Keeping the data network online has become a main concern for most organizations. The best way to ensure maximum productivity is to install a robust cabling infrastructure that offers ample headroom to accept high traffic at peak periods - yet is still cost-effective to install and operate. This is where the IBDN System 1200 saves the day. System 1200 is built using IBDN PS5 Enhanced Connectivity and IBDN 1200 series UTP cable. This powerful combination of advanced connectivity and cable gives you data transmission capability of 1.2 Gbps - with enough margin to cope with heavy traffic bursts.
The industry is fortunate to have many years of experience behind it when it comes to manufacturing high performance network cable. But a network is not just good cable, it's a combination of cable and connectivity. Now, more than ever before, networks will depend on matched components - connectivity and cable - to perform at levels able to meet network users' demands.
IBDN PS5 Enhanced Connectivity has been specifically designed to complement the IBDN family of high performance cables. Designed from the start as a complete, end-to-end system, IBDN cable and connectivity work together to deliver network performance unlike any other system in the industry. In fact, IBDN cables enhanced connectivity is tested individually, and again as part of the IBDN system. IBDN's comprehensive test results mean you can reliably transmit voice, data, video, as well as control applications, all over one system.
Many network administrators believe that putting together a piece-parts system from a variety of manufacturers will result in a system that meets industry standards. Perhaps. However, keep in mind that standards are the minimum level at which components, and therefore systems, must perform.
And piecing together components which may have never been tested together as a system may produce disappointing results. The channel is dependent on component interaction. As such, it is only as strong as its weakest link, and in many cases, that weak link will drag the whole system down to unacceptable performance levels. Mismatched components may not have been a serious issue in many 10Mbps or even 100Mbps transmission environments, but with gigabit networking upon us, the network will be much more sensitive to impedance mismatch and imbalance which can disrupt data transmission. In other words, creating an end-to-end structured cabling system is not equal to the sum of the parts. It takes serious commitment in design, manufac-turing and installation.
Moreover, most component vendors simply cannot offer a system certification or warranty program to protect your investment against rapid obsolescence. IBDN Gigabit Cabling Solutions can be certified to ensure that the system meets stringent installation guidelines, and most importantly, that it will run the applications it is designed for, over the life of the structured cabling system. IBDN Gigabit Cabling Solutions can be performance certified. So the network is completely optimized.

The use of timely, accurate information is a key requirement for any successful business today. The caliber and performance of an information systems and the networks, they run on can mean the difference between success and failure in today's competitive business environment. What is often overlooked, however, is the critically important role that the cabling system plays in supporting your Information Technology systems.
Your cabling infrastructure typically accounts for a small portion of the total IT systems and networking investment, yet an improperly designed or installed cabling system can be the cause of chronic network problems that may prevent people from ever realizing the true potential of the IT strategies.
Moreover, the negative impact of an inadequate cabling infrastructure will only become more evident as people add new applications, more users and faster networking speeds throughout a business - both today and in the years to come. Now is the time to develop and implement an effective structured cabling decision into the overall IT systems and networking strategy.
