If your organization is considering a new VOIP (Voice Over Internet Protocol) system, you should think about the structured cabling system needed to support it and maximize its potential. The following summarizes the advantages your digital phone system will have with a well-designed structured cabling system.

Decreased Noise

CAT 6 and CAT 6A cable provides more noise reduction than older cables. Fiber optic cabling is even better. Less noise resistance results in more static and faulty connections during phone conversations. Higher levels of noise also decrease network speed because the system is forced to retransmit data until it is no longer corrupted. Although purchasing lower quality cable saves money in the short run, it may result in long term business losses because of slower response times and annoyed customers.

Lengthened Runs

Higher quality cable will be capable of supporting longer runs that are free of artifacts and errors. Fiber optic cables are not restricted by the length of runs. It is the superior option for a data center or business telephone system because of its excellent noise resistance and high speed. Although second choices, CAT 5e to CAT 6A cabling are capable of supporting runs to 100 meters without noise. Cables that can support long runs provide greater flexibility for layouts, decreasing the need for data hubs or repeaters and increasing reliability.

Maintenance Savings

CAT 5e, CAT 6, and fiber optic cables are highly dependable. However, if they ever become faulty or the network needs to be reconfigured, a structured cabling system that is well organized and diligently marked will save time spent on maintenance. While a company’s network is down, business may be impacted, resulting in lost revenue. Tracing faults is made much easier by a sound structured cabling system.

Transmission Speed

Business is often time-sensitive, and you will want to use the highest quality cable your company can afford. CAT 6A cable is capable of supporting a maximum of 10 Gigabits per second while CAT 5e can only achieve 100 mbps. Older, less capable cables are not recommended because their slow data transmission and high noise levels cannot meet current VOIP demands.

As mentioned previously, modern data centers must be flexible, scalable, reliable, and manageable, making best practices required. Part 3 will cover Color Identification and Naming Scheme.

Color Identification

A method of fast visual identification, color coding makes management simpler, conserving time spent on the tracing of cables. Patch panel ports can also be coded, and various colored jacks and inserts are also coded. As determined by a particular manufacturer’s own color scheme, cables are available in numerous colors, each of which can be made applicable to the specific function of a cable or connection type.

Color schemes are expandable through the use of color bands at the end of every cable, using various colored sleeves and colored ports on the patch panel. However, it will also be necessary to use a secondary non-color scheme to make it possible for those who are color blind to identify the cables.

Naming Schemes

After determining the physical layout for the cabling that will be used, use a naming scheme that can be logically applied for facilitating fast and effortless identification of every cable component. Labeling can be an especially effective way to improve team communication among staff members because it makes confusion and uncertainty unlikely when a colleague must search for a particular component. Clear labeling is integral to the success of the naming scheme, and it should not be neglected.

A good naming scheme documents and labels every cable component. The following is the typical hierarchy for a naming scheme: Building, Room, Rack, Patch Panel, Workstation Outlet, Port, and Cable. Each should receive a designation indicating its location preceded by the area(s) above it. For example, Rack A03 would receive the designation SJ01-5D11-A03, if Room is designated SJ01-5D11, and Building is designated SJ01.

Upon the approval of the naming scheme, your team can begin labeling components. The team should prioritize drafting a manual that details the naming scheme and include it as part of the training program for newly hired data center administrators.

The Best Practices for Cable Component Selection will be discussed in the next series.

The selection of proper cabling has become more crucial and also more complicated, but the process can be made easier by knowing about the choices available and updates regarding the development of Category 8 (CAT 8).

There are several organizations that determine the standards for cabling, such as the ISO (International Organization for Standardization), IEC (International Electrotechnical Commission), TIA (Telecommunications Industry Association), and CENELEC (European Committee for Electrotechnical Standardization). However, our discussion will primarily focus on ISO/IEC and TIA.

As its standard calls for 10Gb/s rates of transmission, 10GBASE-T cabling is the fastest in the market. Unable to support 10Gb/s, Category 5e does not receive 10GBASE-T standard recognition.  In addition, advisories by the TIA and ISO/IEC and TIA state that new class E/category 6 cabling should not be installed to support 10GBASE T. As a result, the cabling options for new installations that meet the 10GBASE-T standards for carrying data up to 100 meters are only found in the class EA/CAT 6A, class F/CAT 7, or class FA/CAT 7A.

Regarding data centers that are newly built, ISO, along with other standards organizations, have determined that CAT 6A should be the minimum grade. The task force overseeing IEEE 802.3 40GBASE-T have drafted the baseline objectives for the future 40 Gb/s standard, which is well beyond the capabilities of CAT 6A.

Cabling of a higher category traditionally matches and surpasses the electrical and mechanical standards of what preceded it. In addition, it is backwards compatible. Although TIA calls for cabling systems to perform at CAT 6A minimum, it will not be adopting CAT 7 or 7A as determined by ISO/IEC. TIA is naming its next class of cabling, Category 8, to differentiate it from ISO/IEC standards for CAT 7 and CAT 7A.

Interestingly, the proposed performance for CAT 8 will not be meeting or exceeding CAT 7A standards for up to 1 GHz. For example, regarding parameters for internal crosstalk, CAT 7A is superior to CAT 8 by more than 20 decibels.

As mentioned in Part 1, a good network upgrade plan will make an analysis determining each aspect of SWOT: Strengths, Weaknesses, Opportunities, and Threats, helping project managers create a clear plan consisting of five phases. Part 1 discussed the first two, Gathering of Requirements and Selection & Design. Part 2 will cover the last three, Implementation, Operation, and Review & Evaluation.

3) Implementation

Proper execution of the first two phases, will allow Implementation to be performed without major issues. However, every neglected task in the first two phases will certainly have to be addressed during Implementation. A sound schedule will provide time for unanticipated problems which will minimize disruptions of the customer’s business. Maintaining communication between project designers and the client throughout installation is crucial for making a project successful.

4) Operation

After the completion of the network implementation phase, the network transitions into a production environment. The network is live and executes the tasks it’s been programmed to perform. The proper completion of all tasks before this phase will minimize unexpected incidents during the network’s operation phase.

5) Review & Evaluation

Once operational, the network’s design and implementation must be studied and assessed in terms of the design’s objectives. Typically, these tasks are performed by design team staff with the help of network members. There will be an evaluation of costs, performance, and environmental fit.

The items below are recommended for this process:

• Make a comparison between user experience and the documented goals, then make an assessment of the design’s performance.


• Make a comparison between planned designs and costs and actual results of deployment, ensuring future projects will learn from these lessons.


• Observe the operation and document all revisions, making sure the system is accountable.

Each phase should practice sound planning and conduct reviews for optimal functioning and successful installation. For ideal results, on-site technicians should participate in all phases of a network upgrade. They will have a better grasp of the project’s goals, and they will able to provide users better service.

Planning the network upgrade for a company requires careful consideration. Similar to other projects, a need is determined, and then the upgrade process is planned from its start to conclusion. Every sound network upgrade plan will make an analysis determining each aspect of SWOT: Strengths, Weaknesses, Opportunities, and Threats. This SWOT analysis will help project managers create a clear plan that defines the tasks required and the order of the workflow.

Overview

A network constructed as a hodgepodge of devices attached using a combination of protocols and technologies is a sign of substandard initial planning. This lack of forethought results in networks that are prone to downtime, challenging maintenance, and difficult troubleshooting. This poor kind of network is commonly found at small businesses that undergo rapid and unanticipated growth. Big companies also experience this when their networks suddenly expand after a merger with or acquisition of another company. In cases where growth is expected, a company will have a better opportunity to properly plan a network upgrade that is less problematic and provide users adequate service.

Five Phases

Network upgrade planning starts after completion of the initial site survey and report. The plan will be typically divided into five phases as listed below, and each will be then discussed individually.

• Gathering of Requirements


• Selection & Design


• Implementation


• Operation


• Review & Evaluation

1) Gathering of Requirements

Once adequate data has been gathered from visits to the customer and site, the ISP design team will make an evaluation that will determine network requirements and write an analysis report.

2) Selection & Design

After the completion of the analysis report, equipment consisting of devices and cabling will be selected. Several designs will be drafted by the design team, and these will be submitted to other project members for feedback.

This process with allow participants to consider the LAN from a point of view of documentation and assess trade-offs in terms of cost and performance. In addition, design weaknesses will be discovered and solutions will be considered. Moreover, this phase will allow prototyping to determine optimum methodology. Prototypes let designers see how the network will operate before final implementation.

Part 2 will cover the next three phases, Implementation, Operation, and Review & Evaluation.

Cabling installation requires a lot of expertise. This is important due to the complexity of networks cables for data and communication services.  There are tools installers use to install and test cables. Some of the instruments include carts and caddies.

Basic Implements

Network carts and caddies hold cable spools for easier pulling. Reels can be set up on the wire cart which can hold 500 and 1000 foot reels. Cables are mounted on bars that slip through bored holes on the mounting framework. The cart contains a large, wide base that prevents tipping when you pull the cable.  Wire caddies secure smaller cable spools which come in lengths of 500 feet or less. And it has dividers that prevent the wires from becoming crisscrossed and twisteded.

Termination Tools

The appropriate termination tool increases productivity. It allows installation and termination of Cat5e and Cat6 jacks onto the connectors on a patch panel.

This "punch down tool" ensures accuracy and consistency. There are three categories: manual, impact and multi-wire. Cable installers can opt for a manual but most consider the impact tool to be the best option.

The fundamental impact instrument is fitted with a spring-loaded head which can be triggered by the installer. Not much force is needed. The spring is released automatically after being compressed. Modern multi-wire tools like the Jack Rapid punch down tool can terminate jacks eight times faster.

You can use several interchangeable blades for various impact tools. However, this depends on your cabling system. The advantages of this tool are its speed, user-friendliness and uniformity of termination. Sophisticated models consist of fixed blades that cut off leftover wire instantly instead of having to use wire cutters. These new products include a handle that is easy to hold, a disposable blade head and fixed band that holds the jack in place.

Other Useful Tools

You might need professional shears to ensure a quick, clean, and accurate cut.  Each job requires cutting of cables and trimming of excess wires.  A premium cable stripper guarantees immediate and hassle-free elimination of exterior insulation from multi-core cables, unshielded twisted as well as shielded twisted pairs. The flexible depth gauge will give better results.  Refrain from using pocket knives or ordinary scissors because you will probably end up damaging the cable. Other functional tools for cable installation are can wrenches for demarcation point boxes; crimping pliers; knives for splicing cables; voltage detectors; modular plug crimpers for telephones; and, probe picks to detect loose or broken connections.
