Planning an Office Move - an IT Perspective Moving an office is a daunting undertaking that, if improperly planned, can add unnecessary expense and lost productivity. From an IT consultant or network administrator's perspective, an office move involves far more than simply moving physical objects from one location to another. Since most problems arise once the move nears completion, plenty of planning should go into the move as early as possible so that the actual move is as seamless as possible. This article offers a summary of the issues you should consider to help you plan an office move that stays within your budget and deadline. While there are infrastructure management consulting firms that specialize in evaluating a new location, determining shortcomings, and ultimately implementing solutions, these services can be quite costly and are not often available in smaller markets. As the IT Consultant, Network Administrator, or all around tech person in your office, the details of the move may fall to you. And while this article is not intended to be an exhaustive list or tutorial on how to institute your move, a few general principles and tips can go a long way towards keeping you, your co-workers, and your bottom line happy. When planning an office move, especially from an IT and network infrastructure perspective, there are three basic considerations: What are your office's current technology needs? What are your future technology and infrastructure needs? What is your budget? First and foremost, be aware of the details of the new location's voice and data network infrastructure, relative to your current and future needs. While your office manager or some other person in charge of moving may be proud of the fact that he/she has found a great deal on a new office space, it is of utmost importance that you, as the IT person, be aware of what you're moving into. From a network cabling / IT perspective, it pays to take careful stock of the new location. If you're a growing multimedia company moving into a space previously occupied by a financial services firm, be aware that the network infrastructure of the pervious tenants may not be sufficient for your company's needs. The previous company may have been content using a network rated at 100 Mbps for their 20 employees (CAT 5), but even only 10 employees in a multimedia design firm will likely have far more demanding bandwidth requirements than 20 people in a financial services firm - which could require a complete re-wire of the entire office. Secondly, make careful note of the the physical layout of the new location, paying particular attention to the location of voice & data network jacks, as well as electrical outlets. Some property managers can make detailed plans and schematics available to you, which can be an invaluable resource. If not, you should carefully measure each room in the new location, and reduce all rooms/areas to a diagram. It should be as accurate as possible. You should note on the diagram as precisely as possible how the existing infrastructure is laid out. Include power outlets, and existing network and phone outlets. The main idea here is to give you a visual sense of where, physically, the puzzle pieces of your office will fit. It is one thing to imagine it in your head or to make a general, rough sketch, but finding out on moving day that a space you had intended for a network printer does not have a network cabling jack or the correct typer of power outlet could cause you uncessessary headaches. Try different configurations and consult with your co-workers and staff for input. Once satisfied, consider how your plan relates to the existing infrastructure. Remember that for a fully wired office, you will need power and network access for each computer or device, as well as sufficient power outlets and telephone jacks. Note any area where coverage is lacking. Depending on how you see your office expanding, also consider future uses for areas. If a wall is going to be empty, could there conceivably be a desk there at some point? Or a network printer, scanning or CD duplication system? Even if it is unlikely, it is wise to have additional network wiring and access points run to currently unused areas. Adding an additional few feet of wire now is much cheaper than expanding later. If your office will be hosting one or more servers, you must also take into consideration the location of the future server room. Will the future location accomodate the number of servers in your office? Will it require new data drops to be installed? Is it properly air conditioned and, if not, can it be fitted with air conditioning? With respect to running network and phone cables throughout the office, there are some important considerations. It may seem an obvious point, but one that many seem to neglect: you should get installers, network professionals, and anyone else who you may need to pay to implement your plan engaged as early as possible. Get a range of quotes, and consult with them fully and completely while planning your new office. Be receptive to their ideas and suggestions, but do not be over-sold or misunderstood. Miscommunications, misunderstandings and vague instructions ultimately cost you money. The initial preparatory thought and work you have done to consider your present and future needs, coupled with your budget, should help them understand your expectations.
What is VOIP? This article introduces the reader to the basics of VOIP, or Voice Over Internet Protocol. The VOIP tutorial attempts to answer, in layman's terms, common questions such as how does VOIP work, what are the benefits and drawbacks of VOIP, and what are the infrastructure requirements to implementing a VOIP solution. Historically, phone calls used a network made up of copper wires and switches that created a circuit between the caller and the person being called. This technology was mature and fairly reliable, but inefficient. Thousands and thousands of copper wires had to be run from house to house, neighborhood to neighborhood, city to city, country to country - and continent to continent! There had to be a pair of copper wires for every call that needed to go from one place to another. The modern solution to this problem uses data networks that allow information - like your audio conversation - to be broken up into packets and shipped over a shared network link. This is much more efficient for many reasons, but we'll talk about two of them here. The first is utilization. If your neighbor's teenager calls his girlfriend and they hold the phone in silence, very little of the phone system's capacity is actually used. In the old, circuit-switched scenario, two copper wires are used for a phone call, whether anyone's talking or not. The second efficiency is one of infrastructure. Instead of building two parallel networks, one for data and one for voice, we can unify the two networks and create a single network that costs considerably less to build out than the dual networks we were building before. This can scale to businesses today. If you use a PBX and VOIP in your business, you cable for data exclusively. You increase the size and capacity of your data network, but maintaining one network with more bandwidth is less expensive than maintaining two networks. Furthermore, if you have multiple offices and you maintain a data link between them, you can keep all of your phone service 'inside' your network, where you control configuration and security. Your phone service will go to the public phone network only when you connect a call to a phone outside of your VOIP network. Another business benefit of VOIP over typical phone solutions is administration. The number is assigned to the phone, not the wall jack, so you issue a phone to an employee, and it works wherever they plug it in. With modern VOIP PBX solutions, you have significant administrative control over things like who your employees can call, when they can call, how long they can talk, who can call them - the range of control can be amazing, depending on your vendor. All of this results in a lower overall cost of ownership for VOIP in many cases. This isn't a generic result, and there are many variables, but for many offices VOIP can cut costs dramatically. But you must remember that this also places your voice services on your data network. Failure of a network element isolates both data and voice service. This is generally uncommon, but you cannot ignore the fact that losing a switch, for instance, will make it impossible for people on that switch to call and report the outage. Another thing you have to consider is whether your data network is robust enough for the data load your VOIP service will place on it. If you have high latency or low throughput segments in your network, VOIP will make this painfully clear. Make sure you understand the performance of your network and the bandwidth requirements of your VOIP solution. A company that has only a single voice call active at a time, on average, has completely different VOIP and bandwidth needs from a company that does telemarketing, for instance, or a customer service call center. Make sure you discuss these issues with any prospective VOIP vendor you work with, so that you don't find out after you implement your VOIP solution that you must now upgrade your data network to support it. VOIP is the future, there's little doubt about that. Data networks will subsume (already have, really) voice communication, and switched circuits are only virtual even now. It's a technology that can be of great benefit to many companies, and if you're thinking of putting in a PBX of whatever scale, it's certainly a solution you should consider, and if you keep all of the requirements in mind, VOIP might just be the right solution for your company now, rather than tomorrow.

Cat5 vs Cat5e vs Cat6 - Which Should You Use? This article discusses primary differences between the various types of computer and telephone (CAT) cabling available, specifically the difference between CAT5, CATe and CAT6. In a nutshell, the primary differences boil down to differences in the way each conveyance media handles network support, crosstalk, and bandwidth. Cat5 vs Cat5e Network support - CAT 5 cable will support 10BASE-T and 100BASE-T network standards, that is it supports networks running at 10 Mbps or 100 Mbps. CAT 5e is an enhanced version of Cat5 that adds specifications for crosstalk (see below). Cat5e cable is completely backwards compatible with Cat5, and can be used in any application in which you would normally use Cat5 cable. However, the added specifications of Cat5e enable it to support Gigabit Ethernet (1000BASE-T), or networks running at 1000 Mbps. Crosstalk - Crosstalk is the "bleeding" of signals between one cable into another, due to a process called induction. This effect can result in slow network transfer speeds, and can even completely block the transfer of signals over the cable. Cat5e cable has been improved over Cat5 cable in this respect, and crosstalk has been greatly reduced. Bandwidth - The bandwidth of a given conveyance media is essentially it's information carrying capacity. The greater the bandwidth of a system, the faster it is able to push data across a network. Cat5 is rated at 100Mhz while Cat5e is rated at 350Mhz. This coupled with other more stringent specifications makes Cat5e ideally suited for networks which plan to operate at Gigabit Ethernet speeds. Bottom Line: If you plan on to implement Gigabit Ethernet, go with Cat5e. Also, the small increase in price of Cat5e over Cat5 is more than made up for by "future proofing" your network's cabling infrastructure. Cat5e vs Cat6 There is a great deal of debate among people about whether new cabling installations should use Cat5e or Cat6. Many people incorrectly assume that by running Cat6 they will then have a Gigabit Ethernet. However, in order to achieve true Gigabit Ethernet speeds, every single component on a network must be gigabit rated, such as the switches, hubs and network interface cards. This isn't to say that there aren't differences between Cat5e and Cat6, however. The general difference between category 5e and category 6 is in the transmission performance. While Cat5e can support gigabit speeds, Cat6 is certified to handle gigabit Ethernet. Additionally, the Cat6 specification is better suited toward environments that are generally unfriendly to twisted pair cabling. This includes areas that have lots of interference from things like power lines, lights, and manufacturing equipment. Still, for most applications, Cat5e is perfectly suitable and preferable to Cat6: it is more economical and performs almost as well. However, if you can be certain that all the components on your network are gigabit rated, and the volume of the data being transmitted calls for certified gigabit performance, then Cat6 is the way to go.

Telephone Technician Training and Certification Program Overviews Telephone technicians repair and install telecommunications equipment. Although many employers offer on-the-job training, completion of a certificate or associate's degree program in telecommunications can help students obtain higher-level positions. Telecommunications Technician Certificate Program Telecommunications technician certificate programs teach students how to use industry-standard tools to install and repair telephone, cable television, fiber-optic and satellite equipment. Maintenance and testing are also part of the training. A portion of the program usually consists of hands-on training in a school-provided shop with equipment or an off-campus company training site. Students are awarded a certificate upon completion and are prepared for entry-level positions in the field. Education Prerequisites These certificate programs typically require a high-school diploma or its equivalent. Previous coursework in electricity, algebra, English, computers, physics and chemistry are also recommended by some schools. Program Coursework The coursework in these telecommunications technician certificate programs focuses on electricity, circuitry, computers, systems, math and digital information. Some common courses include: Direct current circuit theory Technical mathematics Telecommunications installation and repair Microprocessors Digital and analog circuits Employment Outlook and Salary Information According to the U.S. Bureau of Labor Statistics (BLS), the median annual wage in May of 2009 for telecommunications equipment installers and repairers excluding line installers was $55,560 (www.bls.gov). The BLS also reported that the highest level of employment was through wired telecommunications carriers, and building equipment contractors and other telecommunications companies were second and third highest, respectively. Continuing Education and Certification Information Telephone technicians can pursue an associate's degree in telecommunications at many colleges. Certificate program coursework may be transferable toward a college degree program. Associate's Degree in Telecommunications Technology These programs cover advanced skills in telecommunication system development, operations, installation and maintenance. Graduates are awarded an Associate of Applied Science (AAS) or Associate of Science (AS) degree in telecommunications technology. Some of the programs offered combine this degree with computer networking training. Education Prerequisites These programs recommend a general background in math, technical and computer skills. Some students may also be required to take math, English or typing courses prior to entry. Program Coursework Any previous college coursework in telecommunications may be transferable into these associate's degree program. Students must also complete general education requirements such as humanities, math, communication, critical thinking, English composition and social sciences. Some common telecommunication classes at the associate's degree level include: Telecommunications technician electronics Technical math Network and computer security and monitoring Wireless communication systems Videoconferencing and voice systems Popular Career Options Graduates of associate's degree programs in telecommunications have advanced employment options. Some career choices include: Network administrator Telecommunications researcher Technical support specialist Telecommunications field service worker System designer Continuing Education and Certification Information Associate's degree telecommunications studies may be transferable into a bachelor's degree program in information technology or network administration. Some schools have cooperating agreements with baccalaureate universities. The Society of Cable and Telecommunications Engineers (SCTE) offers a voluntary certification for telephone technicians who pass an examination and maintain continuing education requirements. Additional training and education opportunities are also available through SCTE and other associations, such as the Telecommunications Industry Association.
An associate's degree in communications technology is the minimum required education for a person interested in pursuing a career as a telephone technician. Telephone technicians are responsible for the installation and troubleshooting of home and commercial phone lines. They are also responsible for setting up voice mailboxes and replacing faulty wiring. An Associate of Applied Science in Communications Technology program focuses mainly on telecommunications courses and requires only two or three general education classes. Many of the communications classes have a laboratory component, and students have several opportunities to gain hands-on experience using communications technology. Some of the skills learned in an associate's degree program in communications technology include the installation and maintenance of residential and commercial telephone devices and fiber optic cable systems. Other topics include VoIP (Voice over Internet Protocol), digital subscriber lines, local area networks and worker safety. A course on interpersonal communication is also likely to be included because telephone technicians interact with co-workers and customers frequently. A co-op or internship component gives students the chance to gain practical work experience; it is typically completed in the last semester of enrollment. Career Information The U.S. Bureau of Labor Statistics (www.bls.gov) provides no information on telephone technicians; however, it does look at the wired telecommunications industry as a whole. An 11% decrease in the employment of wired telecommunications professionals is expected for the 2008-2018 period. The primary reason for this poor job outlook figure is the increased movement towards fiber optic cables, which are reliable and require very little maintenance. The BLS also reports that the median hourly wage of a telecommunications equipment installer and repairer was $26.73 in 2008. However, Payscale.com reports that the median hourly rate for telecommunications equipment installers with 1-4 years of experience was between $10.91 and $15.13 in 2010. This rate may reflect the potential salary range of a recent graduate of an associate's degree program in communications technology.
Technology is the making, modification, usage, and knowledge of tools, machines, techniques, crafts, systems, methods of organization, in order to solve a problem, improve a preexisting solution to a problem, achieve a goal or perform a specific function. It can also refer to the collection of such tools, machinery, modifications, arrangements and procedures. Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The word technology comes from Greek τεχνολογία (technología); from τέχνη (téchnē), meaning "art, skill, craft", and -λογία (-logía), meaning "study of-".[1] The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology. The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons. Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms. Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations.
processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time, discrete frequency, or other discrete domain signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. DSP includes subfields like: audio and speech signal processing, sonar and radar signal processing, sensor array processing, spectral estimation, statistical signal processing, digital image processing, signal processing for communications, control of systems, biomedical signal processing, seismic data processing, etc. The goal of DSP is usually to measure, filter and/or compress continuous real-world analog signals. The first step is usually to convert the signal from an analog to a digital form, by sampling and then digitizing it using an analog-to-digital converter (ADC), which turns the analog signal into a stream of numbers. However, often, the required output signal is another analog output signal, which requires a digital-to-analog converter (DAC). Even if this process is more complex than analog processing and has a discrete value range, the application of computational power to digital signal processing allows for many advantages over analog processing in many applications, such as error detection and correction in transmission as well as data compression.[1] DSP algorithms have long been run on standard computers, on specialized processors called digital signal processor on purpose-built hardware such as application-specific integrated circuit (ASICs). Today there are additional technologies used for digital signal processing including more powerful general purpose microprocessors, field-programmable gate arrays (FPGAs), digital signal controllers (mostly for industrial apps such as motor control), and stream processors, among others.
A speakerphone is a telephone with a microphone and loudspeaker provided separately from those in the handset. This device allows multiple persons to participate in a conversation. The loudspeaker broadcasts the voice or voices of those on the other end of the telephone line, while the microphone captures all voices of those using the speakerphone. Many telephones have an integrated speakerphone function which can be activated by pushing a single button. This button transfers the sound input and output from the handset to the ambient microphone and loudspeaker. Devices designed specifically for speakerphone use often have multiple microphone inputs arranged radially around the device to maximize sound input, such as may occur around a conference table. The most sophisticated units allow the connection of additional satellite microphones that can be placed some distance from the main unit. [edit]Types of speakerphones Speakerphones may be broadly divided into two classes of Duplex: Half-duplex Full-duplex Half-duplex speakerphones only allow sound to travel in one direction at a time, either: 1) into the speakerphone from the telephone line and out of its internal speaker to its user, or 2) from its user, into the microphone, and out through the telephone line. While the users of the speakerphone are speaking, the phone only transmits sound to the telephone line; its internal speaker is cut-off and no sound arriving from the telephone line can be heard by the user. While the user of the speakerphone is quiet, the speakerphone only receives sound from the telephone line and its internal speaker broadcasts that sound to its user. There is a very definite, noticeable switching action each time the phone "changes directions" and a cough or other transient noise in the room may interrupt incoming sound from the far end of the telephone connection. Full-duplex speakerphones are able to transmit and receive simultaneously and there is no discernible change of transmission direction. These phones are much more complicated and often employ sophisticated digital signal processing algorithms to sort out the incoming sound and the sound in the room for echo cancellation. Their cost is also higher than for a half-duplex speakerphone. [edit]Speakerphone setup Many modern speakerphones must first be calibrated to the acoustic characteristics of the room in which they will be used. During this calibration phase, they may make a variety of noises including ascending tones or chiming sounds. This calibration may be automatic or manually invoked by the user, and it may need to be repeated if the speakerphone is relocated within the room. A failure to be properly calibrated can be indicated by the occurrence of echoing, ringing sounds, or feedback. [edit]Handset vs. base speakerphone Many cordless telephones have a handset speakerphone as well as a base speakerphone. The handset speakerphone allows hands free conversations away from the base unit. The base speakerphone is located in the base unit. The user must be at the base unit, but still gets the added benefits of having hands free conversations. Most base speakerphones have a secondary keypad for dialing calls on the base unit.
An engineer is a professional practitioner of engineering, concerned with applying scientific knowledge, mathematics and ingenuity to develop solutions for technical problems. Engineers design materials, structures and systems while considering the limitations imposed by practicality, safety and cost.[1][2] The word engineer is derived from the Latin roots ingeniare ("to contrive, devise") and ingenium ("cleverness"). Engineers are grounded in applied sciences, and their work in research and development is distinct from the basic research focus of scientists.[2] The work of engineers forms the link between scientific discoveries and their subsequent applications to human needs. A typical lineman's handset integrates an earpiece, a mouthpiece, a dialing interface, and a set of test leads for connecting to the telephone circuit. Originally, lineman's handsets featured a rotary dial, but modern sets use some variant of the standard 12-button DTMF keypad. Most handsets are designed to be used with analog "POTS" lines, and have limited or no function with digital circuits.
Technician is a worker in a field of technology who is proficient in the relevant skills and techniques, with a relatively practical understanding of the theoretical principles. Experienced technicians in a specific tool domain typically have intermediate understanding of theory and expert proficiency in technique. As such, technicians are generally much better versed in technique compared to average layman and even general professionals in that field of technology. For example, although audio technicians are not as learned in acoustics as acoustical engineers, they are more proficient in operating sound equipment, and they will likely know more about acoustics than other studio personnel such as performers. Technicians may be classified as either skilled workers or semi-skilled workers, and may be part of a larger (production) process. They may be found working in a variety of fields, and they usually have a job title with the designation 'technician' following the particular category of work. Thus a 'stage technician' is a worker who provides technical support for putting on a play, while a 'medical technician' is an employee who provides technical support in the medical industry or to the medical profession.
