WEEK 6 : EXCHANGE

WEEK 6 : EXCHANGE

    Exchange is basically switched telephone connection between different office and phones usually used in large offices to facilitate communication between various employees in this case.

6.0.1 WHY EXCHANGE?

    Let us take an example to illustrate this. Let us take a office with 100 offices for 100 employees. Let us assume you are in this office as "boss". Suppose you want to relay some information to one of your subordinates. Now you have a couple of options here.

1) Go to the office of your subordinate and convey him the information.

2) Order your Personal Assistant to call him and then convey the information

3) Convey the information to your Personal Assistant and then he conveys it to the employee.

    The First and second method are time consuming. Also if some query is there it will take even more time. The third method can involve incorrect convey of information plus the query problem is still not solved.

    To facilitate this we use telephone exchange. Here a phone is connected to each of the offices by a central exchange (analogous to switch) and a code is assigned to each of them. Now you have to simply enter this code in your telephone and your work is done

    Telephone exchange has one another advantage. For example you have your office in Delhi and you have to call to another branch of the office at Surat. Let us assume similar case is with 25 of employees and you only have one landline connection. So all 25 of your employees will come at your office to make the call. "DISTURBING isn't it" You are already busy and now this. It can be solved by telephone exchange. Just give a code to the landline number and the employees will enter the code and converse with the other office. After all it is highly unlikely that two people at once will call together.

6.0.2 Exchange: What to expect??

    The whole material in the training can be divide into two parts

1) Telephone Exchange :- It is used in a single office. It is basically a a network of telephones connected to centrally controlled switch (EXCHANGE)

2) OFC network :- used to interconnect offices in large area or intra office connection. It requires high speed which is fulfilled by OFC network.

Even though we alternated between above two parts I will take one topic at one time
