Effective cable management

Cable management, like any other management, starts at the beginning. If you take care of your cable placement while installing your devices, then you will not have to worry about things afterward. If possible, use cables with fire proof jackets. Design your equipment placement and cable routes in such a way that the individual cables have plenty of space and look neat as well. Take care of the cable factor while adding equipments and servers. You may even use wire tacks or metal conduits (metals are fire resistant, after all) to cover up cables, as well as keep everything neat and fireproof. The tacks should be fire resistant.

If you already have a messed up server room, then you will have to look at other cable management options. You could use accessories such as cable trays, cable trunking, and cable baskets for the purpose. Cable trays, made of metal (aluminum, steel, or galvanized steel) are commonly used in industrial and office settings to manage cables. The trays could be either ventilated, which allow for air circulation, or solid bottom, which gives maximum protection but would require additional fittings or cutting for cable to get in or out. Plastic trays are also available, but these are not be fire resistant.

Cable baskets are meshed conduits (which look like baskets) that can contain your cables and keep them out of the way. They are even useful with desk equipments, such as your computers or television monitors. They are not permanent and are probably among the easiest and cheapest cable management systems. Cable trunking is similar in the sense that it is a common name given to most of these cable conduits (permanent), cable wraps, and cable organizers (which cover cables on three sides). Source

When establishing a data network, there are certain things that should and should not be done during the data cabling process. One of the most vital things to do is establish a home-run location where all cables terminate. Making this unit large enough to house the current network as well as any future expansion is a wise idea. This prevents the business from having to find other space within the building or do a build-out.

The best data cabling providers will cross cables only at 90-degree angles, preventing any substantial interference. Labeling the cables is something that should be done as each one is strung. This will allow network support professionals to quickly identify which room or office the cable is designated for and how it must be terminated. As the number of cables in the area grows, this task becomes even more essential to efficient operations.

Professional installers run Ethernet cables everywhere during the data cabling process. This is made easier when access to open walls is available during the construction process. It is best to have the cables in as many locations as possible so they can be easily accessed. Even rooms that have only one Ethernet port can incorporate a router that allows more at a future time.

Using mud rings is something else these companies will do because these are low voltage, eliminating the need to terminate the cables. Mud rings are the most practical for coaxial and telephone Ethernet cables. These inexpensive items are designed for mounting a wide range of low voltage devices. Unused positions are often filled with a blank strap and then covered using wall plates, resulting in a clean installation.

As far as what these companies should never do, mixing the color scheme of the data cabling tops the list.  One color should be used for each purpose, such as white for telephone, blue for data, and so forth. Professionals will also never run a Cat5 cable alongside a power cable because this often results in interference. Lastly, though different types of cables can be run together, they should not be bundled too tightly. If the turns are not soft, a kinked cable could result and negatively impact the network.

As you can see, there is a lot to consider when doing data cabling and this is not a job for those who are inexperienced. Hiring a professional to perform this service can save a lot of time and headaches for any business. As the organization grows, the professional service provider can be called to expand the cabling. Using a professional means minimal down time and optimum network performance. Source

We tend to think of digital communication as a new idea but in 1844 a man called Samuel Morse sent a message 37 miles from Washington D.C. to Baltimore, using his new invention ‘The Telegraph’. This may seem a far cry from today’s computer networks but the principals remain the same.

Morse code is type of binary system which uses dots and dashes in different sequences to represent letters and numbers, modern data networks use 1’s and 0’s to achieve the same result. The big difference is, that while the telegraph operators of the mid 19th Century could perhaps transmit 2 or 3 dots and dashes per second, computers now communicate at speeds of up to 1 Giga bit, or to put it another way, 1,000,000,000 separate 1’s and 0’s every second. Not long after Morse’s Telegraph, a French inventor called Emile Baudot developed a printing telegraph machine which used a typewriter style keyboard, this allowed virtually anyone to send and receive telegraph messages. Baudot used a different type of code for his system because Morse code didn’t lend itself to automation, this was due to the uneven length and size of bits required for each letter. Baudot used a five bit code to represent each character, this would normally only give 32 possible combinations (00000 to 11111 = 32). It clearly wasn’t enough for 26 letters and 10 digits but he got around this problem by using two ‘shift characters’ for figures and letters, which performed the same sort of function as a typewriter shift key. Now he had 62 combinations for letters, figures and punctuation marks. To this day, the speed of serial communications is still measured in Baud rate, after Emile Baudot.Improvements were made to Baudot’s machine by an English inventor called Donald Murray. Murray sold the rights for his machine to Western Union who gradually replaced all of its Morse telegraphs with the new ‘teletypewriters’.

Despite its long running success, the Baudot five bit code could only use ‘upper case’, so it had to be replaced with something that would allow more alphanumeric characters to be used. In 1966, a group of American communications companies got together to devise a new code, this time they used 7 bits which could represent 128 characters. This is known as the American Standard Code for Information Interchange or the ASCII code. It was immediately accepted by nearly all of the worlds computer and communications companies, except of course IBM, who decided to make their own standard.

IBM’s version is the Extended Binary Coded Decimal Interchange Code or EBCDIC, it uses 8 bits and can represent 256 characters, but apart from using it in their mid range and mainframe computers, it never really caught on. Not to be completely out done, IBM adopted the ASCII code but extended it by using an eighth bit so it could represent 256 characters, they called it ‘Extended ASCII’.

Although the telegraph and the teletypewriter were the forerunners of data communications, it has only been in the last 30 years that things have really started to speed up. This was born out of necessity, as the need to communicate between computers at ever increasing speeds, has driven the development of faster and faster networking equipment and, higher and higher specification cables and connecting hardware.

Development of new network technology

Ethernet was developed in the mid 1970′s by the Xerox Corporation at their Palo Alto Research Centre (PARC) in California, and in 1979 DEC and Intel joined forces with Xerox to standardize the Ethernet system for everyone to use. The first specification by the three companies called the ‘Ethernet Blue Book’ was released in 1980, it was also known as the ‘DIX standard’ after their initials. It was a 10 Mega bits per second system (10Mbps, = 10 million 1′s and 0′s per second) and used a large coaxial backbone cable running throughout the building, with smaller coax cables tapped off at 2.5m intervals to connect to the workstations. The large coax which was usually yellow became known as ‘Thick Ethernet’ or 10Base5, the ’10′ refers to the speed (10Mbps), the ‘Base’ because it is a base band system (base band uses all of its bandwidth for each transmission, as opposed to broad band which splits the bandwidth into separate channels to use concurrently), and the ’5′ is short for the systems maximum cable length, in this case 500m.

The Institute of Electrical and Electronic Engineers (IEEE) released the official Ethernet standard in 1983 called the IEEE 802.3 after the name of the working group responsible for its development, and in 1985 version 2 (IEEE 802.3a) was released. This second version is commonly known as ‘Thin Ethernet’ or 10Base2, in this case the maximum length is 185m even though the ’2′ suggest that it should be 200m.
In 1984, IBM introduced Token Ring which was able to transmit data at 4Mbps, this system uses a thick black 2 pair shielded cable with large 4 pole connectors. The IBM data connector, or IDC as it is sometimes called, was an engineering masterpiece. Instead of the normal plug and socket arrangement of male and female gendered connectors, the Data Connector was designed to mate with itself, a sort of hermaphrodite. Although the IBM Cabling System is to this day a very high quality and robust data communication media, it has lost favour with a lot of customers. This is partly due to its large size and cost, and partly because it only has 4 cores and therefore is not as versatile as an 8 core UTP.

It is rumoured that Type 1 cable was originally tested to 300MHz even though it was only categorized as a 20MHz cable for Token Ring, and the newer version, Type 1A was reportedly tested to 600MHz and categorized as a 100MHz cable.
There were many other types of network at that time (too numerous to mention here), which used different types of cables and connectors, so it soon became clear that a standard for telecommunications wiring was needed.

In 1985, the Computer Communications Industry Association (CCIA) asked the Electronic Industries Association (EIA) to develop a cabling standard which would define a generic telecommunications wiring system for commercial buildings, that will support a multi product, multi vendor environment. In essence this would be a cabling system which would run all current and future networking systems over a common topology using a common media and common connectors.

By 1987 several manufacturers had developed Ethernet equipment which could utilize twisted pair telephone cable, and in 1990 the IEEE released the 802.3I Ethernet standard 10BaseT (the ‘T’ refers to Twisted pair cable). In 1991 the EIA together with the Telecommunications Industry Association (TIA) eventually published the first telecommunications cabling standard called EIA/TIA 568, the structured cabling system was born. It was based on Category 3 Unshielded Twisted Pair cable (UTP), and was closely followed one month later by a Technical Systems Bulletin (TSB-36) which specified higher grades of UTP cable, Category 4 and 5 (Cat 4 & Cat 5).
Cat 4 specified data rates of up to 20MHz and Cat 5 up to 100MHz which at the time must have seemed like ample bandwidth for future development, but now, less than ten years later, even Cat 5 is being pushed to its limits by new networking technologies.

Recent developments have been Cat 5e, Cat 6 and Cat 7 standards, and more information on these can be found on the Questions and Opinions page.

Google launched the service to take on online communications pioneer Skype.

Local users logged-on to their accounts yesterday to discover a new directory of phone contacts listed under a voice calling link, along with an offer for some free calls and prices for international calls to landlines and mobiles.

A Google Australia spokeswoman confirmed the phone lists are compiled from data extracted from users’ emails and chat sessions.

Google has not responded to repeated requests for clarification on the nature of internal account searches and the extraction methods used to populate personal web phone menus, nor has it indicated whether it sought users’ approval before taking action.

But online privacy advocates say it appears Google has not learned from outrage over the Buzz social networking tool that automatically connected users based on data mined from personal emails and chat sessions, nor from the angry reaction to Facebook changes to privacy settings that exposed previously hidden material.

“As far as I can see, Google has done this without even notice, let alone consent,” said Roger Clarke, chair of the Australian Privacy Foundation. “And they’ve learnt so little that they seem not to have offered an opt-out.”

David Vaile, executive director of the University of NSW’s Cyberspace Law and Policy Centre, said it appeared Google’s auto-exposure tools were getting a little out of control.

“This has shades of Buzz,” he said. “When will big data-mongers ever learn that opt-in is much more respectful than ‘opt-out – if you can’.”

Mr Vaile questioned whether Google had clearly and transparently disclosed their use of its tools to everyone potentially affected by their operation.

Google confirmed that local users registered under the English-US language setting can access the web phone service, that has not officially launched in Australia.

FixTel has  a wide range of Australian broadband plans to choose from which can be a little confusing so we’re here to make your broadband choice as easy as possible. There is three main types of broadband which are fixed broadband plans, mobile broadband plans and wireless broadband plans. Fixed broadband deals describe a fixed line, usually an adsl broadband line which provides your connection, adsl broadband plans are the most common type of broadband deals at the moment but that’s changing. Wireless broadband plans are essentially adsl broadband deals which have a wireless router which means once your broadband connection reaches  the router it becomes wireless so you can use it anywhere in the house on multiple computers or laptops. Wireless broadband can be sometimes wrongly confused with mobile broadband plans. Mobile broadband deals involve no fixed line whatsoever but rely on the 3g broadband coverage of the mobile networks. Mobile broadband plans are accessed via a usb stick, sometimes called a mobile internet stick which plugs into your laptop allowing you to get online instantly, so long as you are in an area of coverage. We can help you choose the right package

Wireless Broadband

Wireless broadband plans have been falling in price and it’s now possible to find cheap deals from a range of different wireless broadband providers. Prepaid wireless broadband is becoming increasingly popular and is a good option if you are on a budget and want to manage your costs closely. As with any internet provider before opting for a cheap wireless broadband plan it’s worth checking the coverage as this may vary from one provider to another meaning that the cheapest option may be a false economy.

Broadband Plans

Broadband plans are available from a wide range of Australian broadband providers and by using our comparison tables you can see how the various broadband plans compare and will be able to find the most suitable internet provider for your needs. Take into account download speed, cost and download limited. If you are a heavy internet user you may want to choose an unlimited broadband plan. If you plan to use your internet connection for online gaming then choose an option with fast upload speeds, download speeds and unlimited downloads. Alternatively if you only plan to browse the web and send emails the cheapest broadband plans should be sufficient for your needs.

Wireless broadband plans

Wireless broadband plans have a similarly large choice in Australia, there are also prepaid wireless broadband plans to consider for those who want to only pay for what they use and keep a tight control on their budgets. These options are also great if you intent on moving home and you are not locked into a lengthy contract as you are with other deals. It’s worth taking this into consideration to ensure you get the best wireless broadband plan for your money.

Mobile broadband plans

Mobile broadband plans have seen a huge surge in growth since 2008 and are now becoming more and more popular. Prepaid mobile broadband plans and contract option both allow you to use your connection anywhere you have mobile reception and on any computer or laptop. To choose the best mobile broadband plan for your needs consider the same things you would take into account for a fixed internet deal like speed, download limits, contract length, costs and the reputation of the mobile broadband provider in question.

Compare broadband plans

Compare broadband plans is what we do so you’ve come to the right place. We compare broadband providers and a wide range of plans to ensure you get a great deal. We compare wireless broadband plans too. As a broadband comparison site we aim to provide all of the information in an easy to use format so you can quickly and simply find the most suitable deal for your requirements at the cheapest price.

Compare mobile broadband

We also compare mobile broadband, our mobile broadband comparison service is quick and easy to use so you can simply find the right offer for your needs. We aim to give you the information you need so that you can compare deals on a like for like basis and make an informed choice.

Best broadband deals

The best broadband deals for one person will not always be the best broadband plan for another. For example an online gamer is more likely to need a high end fast broadband service with high speeds and unlimited downloads, an occasional user would be fine with a cheap broadband option and business users or students who want to get online in different places may find mobile broadband the best option for them. Equally the best mobile broadband options will differ from one person to another so make sure you take into account who you will use your connection before committing to a contract.

Cheap broadband

Cheap broadband plans can be great for light or occasional users but make sure you are not sacrificing the features you need by opting for the cheapest broadband plan available as this can be a false economy. Make sure the internet provider you choose has good coverage in you area and has sufficient speeds and download limits for your type of internet use. It’s also worth considering customer service which varies between Australian internet providers from the good to the bad when looking for a cheap broadband plan.

Broadband speed test

Unsure of your broadband speed? Our internet speed test and run a broadband speed check to see how fast your connection is. You can visit our free broadband speed test to see how your provider stacks up against the competition.  Our broadband speed checker  measure upload and download speed for your internet connection. If you are unhappy with you current provider you can run might want to run broadband speed test and consider switching to an alternative internet provider if you are unhappy with your internet speed. You can visit our internet speed test here.

Govt open to Telstra Bill changes

The government has indicated for the first time that it is “open to amendments” on the Telstra separation Bill due for debate this Thursday.

“The government will always have an open mind to amendments that it believes will improve the Bill,” Communications Minister Stephen Conroy’s Office wrote in a statement on Friday evening.

The Telecommunications Legislation Amendment (Competition and Consumer Safeguards) Bill 2009 has offered Telstra a choice to voluntarily opt for structural separation or face an imposed functional separation coupled with tough sanctions, including a ban on acquiring spectrum for 4G wireless services.

The government is “determined to debate and pass the Bill early this year,” Conroy’s office wrote.

The government hoped to reintroduce the Bill to the Senate this Wednesday; however, it has been pushed back to Thursday due to various health Bills, leaving little chance for it to be passed until Senate resumes on 9 March.

Independents as late as last week were yet to hear from Conroy regarding their concerns over the Bill, with Greens’ Senator Scott Ludlam questioning what exactly would be in it. Ludlam, Independent Senator Nick Xenophon and Family First Senator Steve Fielding have all indicated they want to see amendments made to the Bill.

The week’s break to 9 March could be seen as giving NBN Co and Telstra a short window to complete negotiations regarding the company’s structural separation, though the company’s CEO David Thodey said two weeks ago that decision would be “months away”. Thodey has also said that any deal with NBN Co must be approved by shareholders.

David Forman, executive director of the Competitive Carriers’ Coalition (CCC), said Thodey’s requirement to get shareholder approval will not stop the Bill proceeding.

“Public policy is not hostage to David Thodey’s opinions on what is agreeable to shareholders. That’s David Thodey’s problem,” Forman told ZDNet.com.au.

The CCC, which represents several carriers’ interests, had argued its case to crossbenchers, Forman said.

“We have had very constructive conversations with crossbench senators on all aspects of the Bill. I’m not sure whether that will translate into amendments, but I have very good reason to believe that these are taken seriously and confident that they will be discussing those changes with the government,” said Forman.

Broadly speaking, CCC has argued for an open process to determine whether Telstra’s proposed form of structural separation to the Australian Competition and Consumer Commission (ACCC) is adequate — if it proposes one prior to the government passing the Bill. It also wants to ensure that Telstra cannot use contract law to overcome pricing determinations made by the ACCC.
