Telecommunication is the term use to refer to a vast array of communication technologies that send information over distances. It is one of the enabling technology behind the internet.

Telecom infrastructures and equipment transmit and receive information or voice and data packets over different modes over very long distances.

Telecommunication is a broad term as it also covers not only data communication such as the internet but includes voice telephony as well. Land line, mobile phone, satellite phones and even Voice-over-Internet Protocol (VoIP) are forms of voice communication under telephony technologies. Without Telecommunication services all e-commerce and internet business-related activities would come to a grinding halt.

There are now a vast array of telecom services that connects all type of devices including computer networks, public telephone networks, television networks and radio networks.

Telecom companies are like hauling companies. They can haul information from one point to another and vice-versa. It can dedicate one particular communication channel to connect a private computer network of one company say to its branch’s computer network located in another country. The service is called international lease line service. Telecom companies offer a variety of service, voice and internet access services are most in-demand.

To get the best and cheapest telecom service, check-out this page on best voice and internet rates. The importance of finding the best telecom service should be stressed especially for start-up internet business.

As mentioned, the internet is a system that interconnects computer networks across the globe and its telecommunication that makes possible.

The internet is a public network free for use by anyone. Users of the internet however will have to pay telecom companies for the service of bringing internet access to their areas and for providing value-added service. Telecommunication companies have to invest millions of dollars on telecom infrastructures

In rural areas,less-populated or less-dense areas, reliable access to internet is a major problem. Despite widespread advances in communication such as GSM/CDMA, Fiber Optics, Satellite and Wireless Systems, some areas are making do with low-speed dial-up access.

Internet business needs access to reliable telecommunication services (e.g- telephone and broadband internet access is essential). Access to voice and data communication is hard especially in rural, remote and isolated areas. Few telecom companies dare to venture in because of very low potential return on investment. Telcos just won’t expand in areas with low projected return on investment.

Internet access via satellite or VSAT is the easiest but not the most cost-effective way due to high cost of subscribing a VSAT service.

In remote regions, local communities and entrepreneurs bonded together to put up a local communication systems in order to have access to telephone and the internet. You can find telecentre or community technology centers that serve as communication hub for the community in remote places.

“Make telephone calls anywhere in the world absolutely free of charge.”

Does this sound as an exaggerated claim? A promotional gimmick?

Well, today, it is actually possible to talk to your near and dear/ your customers and business associates absolutely free (or with a nominal calling charge). With the latest VoIP technology sweeping the arena of telephony, talking free of cost is no longer a long-cherished dream. It is a hardcore reality!
VoIP is indeed a revolutionary technology that will eventually change the face of the existing telephony system.

What is VoIP?
VoIP (Voice over Internet Protocol) is a technology that is used to transmit voice or audio files over the Internet via a packet-switched network. The voice/audio files can be received by:

• a computer
• a VoIP phone
• a standard telephone

The VoIP technology enables the transmission of voice/audio data as digital data over the Internet.

A number of practical applications based on the VoIP technology are gaining popularity among people as a means of economical communication. They are:

• VoIP phones

dedicated instruments to make calls over the Internet

• ATA sets

telephone-like boxes that connect to a computer and convert the analog voice data into digital signals

• computer to computer calls

need a computer system, headsets and Internet connection

VoIP phones are slowly gaining foothold in the market due to their efficiency in meeting the financial and infrastructure needs of corporate houses. These phones are also known as ‘broadband phones’ as they can be used to make calls over the high-speed Internet connection.
A VoIP phone converts voice data into digital data so that the data may be transmitted over the Internet. You need to connect the phone to a computer to enable voice communication.
VoIP phones look just like the standard telephones with the cradle, the buttons and the handset. So, you can make calls in the usual way…but with better sound quality and in an economical manner!

What is VoIP?

VoIP is nothing but Voice over Internet Protocol, which has taken the world by storm. VoIP is both the cause and consequence of a shrinking world. Now one does not need to spend huge amount of money on making international calls. Simply with the help of Internet, one can make calls in any part of the world without having to burn a whole in the pocket.

VoIP, also known as IP Telephony or Broadband telephony, is basically routing the voice messages over the Internet or through any other kind of IP based network services. There are dedicated service providers which are basically companies that provide such VoIP services to common people on an individual basis or in a group, however VoIP services are mostly used by corporate houses. These service providers use protocols to carry out voice signals over the IP network and they are commonly known as Voice over IP or VoIP protocols.

VoIP is increasingly replacing the POST or Plain Old Telephone System. Now more and more organisations are switching over to the latest mode of communication. This has become a necessity as companies are extending their client base abroad and till far away from their country. Now you can speak to your client sitting in Middle East or China or USA or just about anywhere where Internet has touched the human life. VoIP ha s decreased the requirement and therefore the cost of traveling tremendously and therefore it is reaching out to more number of people in more number of countries.

Suppliers of VoIP

VoIP has spread its wings far and wide. And the spread has become possible due to increasing number of VoIP service providers. These suppliers provide the VoIP services on the basis of plans. One can choose services as per the requirements or the frequency at which one needs to make international calls. You can also choose to take the help of leading suppliers of traditional telephones or cordless phones, who are providing VoIP services.

Your business intends to make extensive use of video conferencing and multi-media applications. How do you determine what bandwidth solution (T1, DS3, OCx/Sonet, etc.) would best meet your needs and incorporate that decision into your network cover these applications?

I’d say that it depends on what kind of service and QoS you are looking at. For example, when you say “video” you mean video conferencing and not something like VoD. The Bandwidth requirements will vary according to your service requirements.

For example: For IPTV services, the image quality depends on the encoding deployed: MPEG-2 consumes approx. 3.75 Mbps, whereas MPEG-4 needs approx. 2 Mbps for the same high-quality image production. Also broadcast TV is delivered using IP Multicast which makes the bandwidth required dependent on the number of channels offered and the encoding rate. 200 channels of MPEG-2 in standard definition will take approx. 750 Mbps of bandwidth. VoD, on the other hand, is a unicast per-viewer channel. 1000 standard definition VoD users will need appro. 3.75 Mbps.

The QoS requirements for video conferencing using H.323 (SIP could be different again) can be planned on the “Rule of 75″ as follows: Calculate the minimum bandwidth required by each of your applications ( e.g., video, voice, data). The total of this bandwidth is the minimum requirement for any given link and it should consume NO MORE than 75% of the total available bandwidth on the link. The 75% rule makes allowances for bandwidth required for over head traffic, such as routing, Layer 2 keepalives and other applications, such as, email, HTTP etc.

So, Capacity planning for H.323, should look like something as follows:

Video data + 20% = bandwidth required.

Example:

Video data rate: Bandwidth Required:

512 kbps = 614 kbps
1.5Mbps = 1.8 Mbps …

For issues such as number of concurent users and more stuff on video conferencing you can perhaps consider looking into Cisco’s solutions offered and also TANDBERG boxes.

Cisco considers anything 766Kb to be a “slow link” for VOIP. Also you need to consider the criticality of the sites so you may need two separate connections. All multi-media applications run on top of your other applications so QoS only allows a preference of who goes first.

You need a good baseline of non-multi-media applications (VOIP). So bandwidth needs to be able to handle all necessary applications in the network.

Also, you’ll need to remember that the bandwidth aggregation at the Data Center needs to meet or exceed all inbound remote site traffic. In other words, if I have three remote sites all with T1s. I’ll need more than one T1 at the Data Center to manage the traffic. Remember unless this is a greenfield then baseline, baseline, baseline!

When it comes to streaming video, bi-directional – you are going to have to consider the quality of the compression you are planning to use. If you are planning on using high definition video 1 direction it is recommended to have at least 2MB in the direction of the video being accessed.

So if you are streaming video to your computer then you need to make sure that you get 2MB download capacity. Also, another thing to keep in mind is latency and loss of packets. I would recommend staying away from wireless for this type of application as it will add latency and cause issues later. DS3 bandwidth and anything higher may be over kill, but would easily be able to handle your demands.

Without knowing specifics, it is hard to provide a precise answer, but, one can still specify a systematic method for calculating required bandwidth. Once you know the bandwidth requirement, then it is all about negotiating the most economical way to order that bandwidth from a network provider in the area.

Here is what I would suggest:

1. Calculate the peak external link bandwidth requirements (inter-office data transfer, video conferencing, email transfers. With attachments running in tens of megabytes, email traffic can’t be ignored these days.).

2. Real time applications being mostly jitter and delay sensitive – so you have to make sure that you will have enough bandwidth when they need it. The bandwidth of video depends on the mpeg profiles used (without going into specific, generally 1.5 Mbps can give you very good video on a PC (equal to VCD quality). HDTV images can take about 20 Mbps – but that is domain more reserved for IP TV service providers). Most current users of interactive video communications will be happy with the images coded and transmitted @ 512 Kbps. This includes audio and video as well as control signaling. So, one should provision at least 512 Kbps per video stream, and more the better (I would say 1.5 Mbps is the good if you are a big organization and use a large TV for video conferences)). So, multiply bandwidth for a single stream by the number of parallel streams required. Now that determines the total peak real time usage.

3. There is no specific rule – but wise men with experience advise to keep the peak real time within 60 to 75% of network bandwidth available leaving the remaining capacity for background traffic. In a small organization of 5 people – it is easy to tell people not to download gigabyte attachments when video conferencing is going on , but in larger organizations it is hard to enforce such things except with router policies (assuming they have QoS support), and you can deal with occasional unhappy users.

4. Now, once you know your bandwidth requirements, it is time to talk to the network operator how they can provide that bandwidth in the most cost effective way.

A fill is nothing to be worried about. The actual procedure takes only about 15 minutes. In the majority of cases doctors now do fills under fluoroscopy, or x-ray, so they can see the port and how the band looks.

When you arrive for your appointment you will be asked to stand in front of the very large x-ray machine. There will be a screen in front of you where you can see your band, tubing and your port depending on where it is placed.

You will take a small sip of barium so the doctor can see how liquids are flowing through your band. You will see the liquid come down your esophagus and fill your pouch. Then after a second it flows through the band and into your lower stomach.

When you are ready for your fill you will lay down on a table with a support under your shoulder blades. This arches your back somewhat so your port “rises” and is easier to locate. Once the port is located the doctor will use a syringe and stick the needle into the port. He or she can see the needle on the x-ray and can see it going into the port. Does this hurt? It is a small needle stick. It feels like getting a shot which is exactly what it is. Some people are more sensitive than others to this.

The doctor will then inject the saline into your band. How much he or she gives you is determined totally by the doctor and the patient’s individual needs. Some give more some give less. This is something you will discuss with your doctor.

After your band has been filled you will stand in front of the x-ray again. You will take several sips of barium to see how tight the band is. If the doctor believes everything looks fine and you are able to drink you are on your way. You will be on liquids for the next 24-48 hours in order for your stomach to adjust to the tightening.

The number of fills a patient will receive is a varied as the number of patients. Some will have one, others will have 5. This is purely determined by the doctor and the patient. The same applies to the amount put into a patient’s band. Some do great with 1cc while others may go as high as 2.5cc. Everyone’s body and needs are different so their treatment will be different as well.
