Bsnl Exchange:-

For smooth working of an exchange following unit are very important:-

1. Computer Unit: - it deals with additional services of the exchange to the customers with the help of computers.

2. Power Plant:- to feed proper power supply to exchange

3. AC Plant: - to maintain the continuous temperature + or – 2 degree Celsius to the digital switch (exchange).

4. MDF: - to connect switch (exchange) with the external environment (subscriber) i.e. it is the interface between subscribers and exchange.

.

Computer unit

As the name specified it is the main part of the exchange that deals with the all services provided by the exchange to the customers with the help of computer. It also provides the updated data to all other part of the exchange.

The customers are using the services of the exchange by using the internet also gets connected to the main server present this room via an internet room.

It mainly consists of the servers that are providing the different services. The main servers of this room are:-

IVRS is used for the change number services provided by the exchange.

CERS are provided by the exchange to avoid the problems that the users are facing the repairing of telephone. In this system when the user enters it’s complained it gets directly entered to the server and user is allotted with an id number.

.

LOCAL DIRECTORY ENQUIRY is another services provided by the exchange, by using this; subscribers calls the particular number and gets the directory enquiry. The server present in the main computer room provides this service.

INTERNET DIRECTORY ENQUIRY is the latest service by the exchange. In this type of service makes it enquiry using the internet, which gets connected to the main server at the internet room in the exchange and further to the main server in the computer room

POWERPLANT

As we know that, the power is the main source or any organization. It is the case of E-10B exchange. That is the first requirement of any organization is the input.The main source of this exchange is AC supply. However, as soon as the power supply is gone off, then what is source?

.

Even if the power supply gone off. Thus there must be adjustment source of power.

The main parts of the power room are:Batteries: - these are the instant sources of the power

as soon as power is gone off.UPS (Uninterrupted Power Supply):- the UPS must

give supply to the computer. As we know there is some equipment which can withstand any type of power supply, but there are also some instruments which cannot withstand with this type of power supply, even a microsecond delay will cause the loss of data.

Charging- Discharging Unit: - the batteries we are using in the power room need timely charging. As soon as the AC power supply is on, we make use of the charging unit present in the power room.

.

Inverter and Converter Unit: - the main use of this system is to change AC mains to DC and vice versa as required by the parts of exchange.

Engine Room:-we know that the batteries are the instant source of supply but we cannot use it for much larger time, thus for this, we have an engine to generate the power supply. They are of 885 KVA. Thus, this room controls the supply of the engine.

CENTRAL AIR CONDITIONER

For the function of electrical equipment, cooling system is basic requirement. The basic advantages of cooling systems are following-It provides the thermal stability so that the temperature does not reach the tolerance limit of electronic equipmentIt saves equipment from dust so to avoid malfunction of equipment’s.It protects equipment from excess humidity which can caused rusting of equipment.

MAIN DISTRIBUTION FRAME:The primary function of MDF is:The fault of telephone number is removed in

the MDF; it is called as Fault Remove Section.These testing are T.T.Y. testing, Group testing,

etc.For any type of testing firstly we need the vertical no. or the live tester, printer and computer test N.E. number of that particular telephone number.The telephone numbers are also disconnected in the MDF because of some specific reason.

ORGANISATION OF THE MDF PARTS:-Horizontal sideVertical side

INTERNET:The Internet is not a program, not

software, not hardware or a big system. It is a group of various co-operating computers worldwide interconnected by computer based on TCP\IP communication protocols.

People use it to get information over a standard communication link. The hundreds or thousands or millions of computer network are connected to each other for exchanging the information which is based on the unique identity and set of procedures.

Internet is a series of interconnected networks providing global link to information.

 

INTERNET TECHNOLOGY

 

The basic function of Internet can be summarized as under

Interconnecting of computers to form a network. Interconnecting of computers to form a network

of networks.To establish a communication link between two

computers within as network.To provide alternate communication link among

the networks, even if one network is not working. These are based on TCP/IP communications protocol.

Transfer of a file through Internet:-Suppose a file is to be transmitted on Internet

from one computer to other ones.

.

Break the file in to small packetsAttached destination and source address in o

packets.Multiplexed and transmit these packetsAt destination de-multiplex the packetsRemove address bits from the packets and

assemble the data in to the original file.Make source bits as destination address and send

the acknowledgement in to the source.Therefore, it is clear that network hardware sends

the packets to specified destination and network software reassembles of communications, the computer network performs the following functions.

1. Addressing and routing2. Fragmentation and error correction

.

Data error checking.Connectivity control.Multiplexing and de-multiplexing.Data flow control.End users interface.The data handling.

A single module cannot handle the entire process. One that adopted as a standard is an open system interconnection (OSI) model.

OVERVIEW OF BROADBAND TECHNOLOGY:- 

DEFINATION OF BROADBAND:- Broadband is the nonspecific term for high-speed digital

Internet access. To state the obvious, ‘broadband’ indicates a means of connectivity at a high or ‘broad’ bandwidth.

There are the various ways to define the broadband:- Term for evolving digital technologies that provide

customers a high-speed data network connection. Provides signal switched facility offering integrated access

to voice, data, video, and interactive delivery services. Delivers services & facilities with an upstream and

downstream speed 200 Kbps or more. Range varies from 128 Kpbs to 100 Mbps.

In fact there is no specific International Definition for Broadband.

 

TECHNOLOGY OPTIONS FOR BROADBAND SERVICES:

Communication of data with different throughput is feasible by following technologies:-

Narrow Band 2.4Kbps – 128Kbps.Broadband 256Kbps – 8000Kbps.LAN 1000 – 100Mbps.Broadband communication technology can be

divided broadly in to categories:-Wire line Technology.Wireless Technology.

WIRE LINE TECHNOLOGIES INCLUDE

Digital Subscriber Lines (DSL) on copper loop.Optical Fibre Technologies.Cable TV Networks.PLC (power line communication).

WIRELESS TECHNOLOGIES INCLUDE:Satellite MediaTerrestrial Wireless3G MobileWi-Fi (wireless Fidelity)Wi Max.FSO (free space optics).

BROADBAND CONNECTION AT HOME:

For Broad band connection at Home or office 5 things are required
