STRUCTURED CABLING (COPPER AND FIBER)
Structured cabling is building or campus telecommunications cabling infrastructure that consists of a number of standardized smaller elements (hence structured) called subsystems.
Structured cabling falls into six subsystems:
§ Entrance Facilities are where the building interfaces with the outside world.
§ Equipment Rooms host equipment which serve the users inside the building.
§ Telecommunications Rooms house telecommunication equipment which connect the backbone and the horizontal cabling subsystems.
§ Backbone Cabling connect between the entrance facilities, equipment rooms and telecommunications rooms.
§ Horizontal Cabling connect telecommunications rooms to individual outlets on the floor.
§ Work-Area Components connect end-user equipment to outlets of the horizontal cabling system.
Structured cabling design and installation is governed by a set of standards that specify wiring data centers, offices, and apartment buildings for data or voice communications, using category 5 (CAT 5E) or category 6 cable (CAT 6) and modular sockets. These standards define how to lay the cabling in a star formation, such that all outlets terminate at a central patch panel (which is normally 19 inch rack-mounted), from where it can be determined exactly how these connections will be used. Each outlet can be 'patched' into a data network switch (normally also rack mounted alongside), or patched into a 'telecoms patch panel' which forms a bridge into a private branch exchange (PBX) telephone system, thus making the connection a voice port.
Lines patched as data ports into a network switch require simple straight-through patch cables at the other end to connect a computer. Voice patches to PBXs in most countries require an adapter at the remote end to translate the configuration on 8P8C modular connectors into the local standard telephone wall socket. No adapter is needed in the U.S. as the 6P6C plug used with RJ11 telephone connections is physically compatible with the larger 8P8C (RJ-45) socket and the wiring of the 8P8C is compatible with RJ11. In the UK, an adapter must be present at the remote end as the 6-pin BT socket is physically incompatible with 8P8C.
It is common to color code patch panel cables to identify the type of connection, though structured cabling standards do not require it, except in the demarcation wall field.
Cabling standards demand that all eight connectors in Cat5/5e/6 cable are connected, resisting the temptation to 'double-up' or use one cable for both voice and data.

you have fared well in the written test and the group discussion. You are just a step away from admission to your dream programme -- the personal interview.
A panel of management experts, a battery of questions. Are you perspiring already?
Well, a personal interview could actually be challenging and fun if you just relax and remain focused. Think of it as a conversation between the interview panel and yourself, so enjoy it thoroughly.
To begin with, there are four main focus areas in any personal interview:
- Personal details
- Academic details
- Your background
- Current affairs
Commandments for every personal interview
Even after months of preparation, some candidates do not perform well inside the interview room. The trick is to follow the below commandments practice them during mock interview sessions diligently. You are sure to crack the personal interview.
1. Whenever the interviewer asks any questions, listen carefully. Do not interrupt him midway. Ask for a clarification if the question is not clear. Wait a second or two before you answer. And don't dive into the answer!
2. Speak clearly. Don't speak very slowly. Be loud enough so that the interviewers don't have to strain their ears.
3. Brevity is the hallmark of a good communicator. An over-talkative or verbose person is disliked and misjudged instantly, so keep it short.
4. If you don't know an answer, be honest. The interviewer will respect your integrity and honesty. Never exaggerate.
5. Never boast about your achievements. Don't be overconfident -- it is often misinterpreted by interviewers for arrogance.
6. Don't get into an argument with the interviewer on any topic. Restrain yourself, please!
7. Remember your manners. Project an air of humility and be polite.
8. Project enthusiasm. The interviewer usually pays more attention if you display enthusiasm in whatever you say.
9. Maintain a cheerful disposition throughout the interview, because a pleasant countenance holds the interviewers' interest.
10. Maintain perfect eye contact with all panel members; make sure you address them all. This shows your self-confidence and honesty.
11. Avoid using slang. It may not be understood and will certainly not be appreciated.
12. Avoid frequent use of words and phrases like, 'I mean'; 'You know'; 'I know'; 'Well'; 'As such'; 'Fine'; 'Basically', etc.
13. When questions are asked in English, reply in English only. Do not use Hindi or any other languages. Avoid using Hindi words like matlab, ki, maine, etc.
14. Feel free to ask questions if necessary. It is quite in order and much appreciated by interviewers.
15. Last but not the least, be natural. Many interviewees adopt a stance that is not their natural self. Interviewers find it amusing when a candidate launches into a new accent that s/he cannot sustain consistently through the interview or adopts a mannerism that is inconsistent with their own personality.
It is best to talk naturally. You come across as genuine.
Mind your body language!
1. Do not keep shifting your position.
2. Your posture during the interview adds to or diminishes your personality. Be a little conscious of your posture and gestures. They convey a lot about your personality.
3. Sit straight. Keep your body still. You may, of course, use your hand gestures freely.
4. Avoid these mannerisms at all costs:
- Playing with your tie
- Theatrical gestures
- Shaking legs
- Sitting with your arms slung over the back of the adjoining chair
Post interview etiquette
1. Make sure you thank the interviewers as a mark of respect for the time they have spared for you.
2. As you rise and are about to leave, make sure you collect up your pen/ pencil/ all other stationery.
3. After getting up, place your chair in its original position.
The last word
1. Some institutes (like the Faculty of Management Studies) ask you to deliver an extempore speech suddenly while the interview is going on. Be mentally prepared for the same.
2. Competition will be very tough. Every mistake you commit will turn into an advantage for the other candidates. Hence, be very particular about your preparation. Do not leave anything to chance or the last minute.
3. Remember you have to sell yourself in an interview.
4. Be very particular about what you write in your resume. Check and re-check your resume for facts, spelling errors, etc. Ensure that there are no grammatical errors in the descriptive type questions in the sheet.
Use these hints, and say goodbye to your interview phobia!
In my own words.. "APPLY APPLY, BUT NO REPLY" .
