Call Centers are getting popular day by day and are considered need of every business whether they are selling products or services. Perhaps it was due to the existence of call centers that the term business process outsourcing was carved. There are a lot of purposes that a call center can serve for you. By definition a call center is said to be  a physical set up with telecommunication capability involving both soft and hard phones and audio and video set up to provide support t  customers by answering their queries, filing complains, making sales and even taking and processing orders.

Some time a call center agent also works as a personal assistant to its client and make to dos list, make appointments and help is scheduling and assisting his or her boss in managing his or her tasks effectively.

Call centers as they serve variety of purposes can be divided into many different types and categories. A few are mentioned below for the over view and understanding of the readers

One type of call center s generally known as the fax call center in which all the faxes are converted and moved to the email address they are easy to manage, store and retrieve as compared to the faxes.

The nest type of call center is like automated call center in which all standardized questions and answers are recorded and customers can get the required information by pressing and opting out the suggested digits. In case a specific customer has unique query the call is forwarded to live customer services agent to handle it.

Usually volume wise a low call center is one that is set up to take hundred calls per day it is sufficient for small business. But by increasing operations the need for large call centers is increasing so people are hiring skilled force in third world countries that form the call center set up according to the requirement of the client. It helps in getting best quality at cheaper rates and is a very successful approach in which winning situation is present at both ends.

Another type of call center is an advanced calling center that can take a large volume of calls that are usually order processing in nature and these call centers work to offer high quality services to the large corporation’s clients on their behalf. A large number of orders can be taken the call center agent can assist customer in placing order online or fill it for her or himself while taking instructions and asking about their choices over the phone.

All the call centers usually provide services of both inbound and out bound calling and work round the clock across the globe and are accessible at every time. The agents usually work in three shifts namely first, second third or morning, evening and night. Thus, a call center is physical building that has a lot of agents to assist customers in placing orders, filing complaints, selling, solving problems and forwarding faxes to mails. Thus call centers businesses are considered successful businesses with low risks associated.

The simplest way to define the function of both the processes of routing and switching in telecommunication is that routing acts to move a telephone call to the access layer, typically to a telephone exchange whereas the final deliverance and decision is made by using the switching process.

Theoretically, switching is defined as a process of actually moving bits in any point on the network where communication lines interface i.e. from an input port to an output port.

In telecommunication, this point of interface is in general termed as the network node and may be a Private Branch Exchange (PBX), a modem, a host computer, a multiplexer or any other similar device.

Normally a switching process relies on the information that is gathered through a routing process and the infrastructure constitutes of specialized computers used to link multiple transmission lines. These specialized computers may be termed as the switching elements that make use of a number of tables formed on the general record of the number dialed and help determine the most gainful and inexpensive trunk over which the call is forwarded. As compared to the complex path determination strategies used by IP routers in the Internet, this process of switching is quite simple and uncomplicated.

Even though both routing and switching are used to transfer information source to destination, the main difference lies in the fact that routing works across an internetwork which means that typically at least one intermediate node is involved in its path. Practically the number of these intermediate nodes may be numerous depending on the network and the path followed. A router is a device that serves to perform two major functions i.e. determining the best possible path in terms of distance and cost effectiveness and the efficient transfer of data or information through this path across an internetwork.

Routers generally make use of multiple routing algorithms which are needed to initialize and uphold the routing tables. These routing algorithms operate on information related to a number of metric variables which may be destination, reliability, load, path length, next-hop associations, delay, bandwidth, and communication cost. A router may use one or more of these variables in order to determine the most effective path for packet transfer.

When it comes to switching in telecommunication it becomes crucially important to mention the circuit switching mode which is the center of voice networks infrastructure worldwide. A circuit switched connection is a temporarily reserved network resource that is dedicated to two subscribers for the complete duration of a conversation. This is why a conversation is continuous and exclusive.  However, as soon as the conversation ends, the connection is removed.

In circuit switching, the exclusive connection requires that a preset share of network resources are held in reserve for the call, and during that duration, no other call is permitted to utilize those resources.

The call request is sent to the destination and only when it is acknowledged by the destination, the data transmission begins.

A huge number of lines are used in circuit switching so as to make the switching and routing computation more cost-effective. Once the connection is established, there is no further need of routing calculations based on complicated algorithms as the line itself becomes dedicated.

While discussing the vast topic of telecommunications, it is important to mention the types of telecommunication network connections that are most commonly used in order to achieve effective communication. They are of three major types. Namely:

Switched Network Connection: This type of network is typically based on switched connections which are also referred to as dialup connections. The network utilizes switches arranged somewhat in a series, in order to establish a connection between the various elements.

Leased-line Network Connection: The second most common type of network connection used in telecommunication is the leased line network commonly referred to as a private line. As the name indicates, this type of network allocates the same particular locations and devices to be connected always. Moreover, the same path is used for data is transmission between the fixed locations and/or devices.

Dedicated Network Connection: The dynamics of this dedicated network connections are very similar to that of leased line. True to its name, a dedicated connection implies that always the same path will be used for data transmission between fixed always connected locations. The difference between the two is however that the end user may own the transmission facility instead of leasing it. This means that dedicated network connection may not be divided among a multitude of locations/users but be exclusive to that user only.

The field of telecommunication utilizes the electromagnetic spectrum, particularly the middle of this spectrum i.e. the radio waves, the micro waves, infrared, and visible light, in order to achieve various forms of communications.

In order to generate information carrying electromagnetic waves these mentioned portions of the spectrum are extensively used.

Even though the end of the electromagnetic spectrum boasts a huge bandwidth,  i.e. of about 1022Hz , the waveforms tend to get highly distorted by a variety of interference sources such as environmental factors like dust, humidity etc.

In addition, sufficient exposure to very high frequency waves such as gamma rays, x-rays, and cosmic rays may prove to be detrimental for human health and hence are not preferred in communication technologies.

In order to best understand PSTN (Public Switched Telephone Networks), which is the most important part of telecommunication, let us compare it to the internet which is also based on the same physical infrastructure.

As the name indicates a PSTN includes devices such as telephones, fax machines, and circuit switches that help to establish temporary but uninterrupted connections. During the entire duration of the call, the circuit established between the two subscribers is kept open. Hence this provides a guaranteed and fail-safe quality of service. While PSTN has been specifically designed to provide optimum efficiency for voice calls, it utilizes the bandwidth rather inefficiently and hence the service tends to cost a tad more than the internet service.

The internet on the other hand serves by connecting networks rather than subscribers. As in PSTN the messages are routed to specific end devices, the same is true for internet, though the messages may be of any type and form ranging from e-mail to instant messaging to audio and video types.

As on the PSTN, messages on the Internet are routed to specific end devices. These messages take various forms, such as e-mail, instant messaging, and real-time audio/video communications. Unlike the PSTN, the internet works on packet data transfer and individual packets may vary their routes accordingly. The end user however, receives the packets in the same fashion as sent as the packets are rearranged at the destination.

Even though this means efficient utilization of the bandwidth, the quality of service is not the same as that of PSTN. Progress is being made on how to improve the quality of service of the internet.
