Voip Telephony

Both modes of voice transmission has its own advantages and disadvantages. For example TDM transmission works on circuit switched mode. If you take a telephone call on a ordinary phone a 64 Kbps is allocated for the entire length of your conversation which makes the quality of voice extremely good…. but we would not be able to make use of the bandwidth allocated for that circuit even if there is lot of idle time during the conversation. Whereas, in case of IP transmission as packets are switched, as long as you are having control over the bandwidth, usage can be optimised giving optimal quality based on our specs. But the key term here is control, if you do not have control over the bandwidth allocation and ratio of concurrent voice channels transmission, then voice quality can suffer if the traffic exceeds the limitation. This is again factored based on the compression equipment in place.

Any traffic on a TDM circuit can be considered travelling over a clear channel relating to the ordinary telephone call example mentioned earlier.

Other differences are TDM is a secure channel, but IP bandwidth if it is on Public Internet can’t be termed fully “secure”. However with the advent of MPLS technology, IP transmission has gained more predominance as packets getting switched has enabled security. Apart from this QoS is possible on MPLS networks and thereby applying CoS on the bandwidth allocate can prioritize voice and data traffic according your specs. (Your MPLS may have a T1 or DS3 bandwidth backbone)

All these points can significantly skew the results in favour of IP transmission over TDM. In a business case scenario, for accommodating multiple voice channels with optimum quality and cost, IP transmission as on date would win hands down. However, this can vary on a case to case basis depending on various other factors which are to be considered.

Now…. if you consider TDM over IP that’s a different ballpark.

TDM over IP is often touted by people as a very “next gen” capability. However, it very often doesn’t make much sense. It’s actually not very bandwidth efficient at all. It’s certainly less bandwidth efficient than TDM circuits over, say, SDH. The reason is regardless of the carrier technology, a TDM circuit like and E1 requires the full bandwidth of the circuit to be reserved across the network. There is no way of compressing it or statistically multiplexing it. The big efficiency benefit of IP networks is due to the statistical multiplexing capability for native IP apps. This benefit is destroyed when dealing with TDM transport.

The only real benefit of TDM over IP is that is *may* allow you to use an existing IP network. This may give you some efficiency that is specific to your application, location, or network setup. there may also be some efficiency in consolidating the management into a single network. There may also be commercial reasons why running over IP is better for you. However, these will be specific to your application. As a general rule, TDM over IP is less efficient than the common alternatives.

Consider that an IP network has to run over a transport network. Often this will be SDH (Sonet). Traditionally TDM circuits would run directly on the SDH network:TDM circuit over SDH. If you run them over the IP layer, then you will have TDM over circuit emulation over IP over SDH. The circuit emulation/IP is an additional layer, and additional layers add overhead.

However, this all depends on whether you have lots of TDM circuits or just a one or two. If you have lots then it may make sense to add the capability to the SDH network. If it’s only one or two, then it may be better (cheaper/easier) to add this to the IP layer.

As I said, TDM over IP over SDH is nominally less efficient (will use more bandwidth) than TDM over SDH. However, specific local circumstances may skew this significantly away from the nominal.

SIP telephony is another fabulous feature for computer users. With every passing year, the computer industry comes up with something bigger and better and Voice over Internet is the most popular big thing to date. VOIP, which is the most common abbreviation used for Voice Over Internet makes use of SIP technology to offer its customers some fabulous features.

Using just the internet, usually high speed connection, you can use SIP telephony combined with VOIP software and make telephone calls right from your computer or even a traditional telephone. What is more is that you will pay much less for this type of telephone service than you would with your regular telephone. It has never been easier or cheaper to make phone calls and in reality, it is starting to make the regular phone companies shake in their shoes, literally.

You will be hard pressed to find too many people who have not started to take advantage of this technology. In fact, more and more people are turning to VOIP and SIP telephony because it is so much cheaper, it does not require any extra phone lines, and the equipment is relatively cheap as well.

You can decide to your own VOIP device or get one from your provider, either way, you are still making an investment that makes sense. There are relatively few problems with VOIP. There are some however, for example, if you lose power, your VOIP telephone may not work. However, this is not much different than if you have a cordless telephone and lose power. The only real difference is that your traditional phone line does not rely on electricity.

If you were to lose your internet connection, your VOIP telephone will not work as well. It requires the internet to work accordingly and if there is no internet connection present, it cannot work as it should. However, the great thing about SIP telephony is that you get all of the same features as you have come to expect from your regular phone. This includes features such as call forwarding, caller ID, call waiting, call waiting ID, caller name and number ID, voice mail and so much more.

Business Strategies for the Next-Generation Network (Informa Telecoms & Media) Feature

Business Strategies for the Next-Generation Network (Informa Telecoms & Media) Overview

Carriers and service providers have united around the concept of the Next-Generation Network (NGN).  Although leveraging a broad basket of Internet technologies, the NGN is not being planned as the next-generation Internet. In its intention and architecture, it is more accurately described as Broadband-ISDN release 2.0.

The NGN transition is hard for both practitioners and observers to understand because it weaves together a number of distinct strands:

The book begins with a review of the failures of previous attempts by carriers to retool for the future. It describes in detail the technologies and capabilities supporting “new wave’” services, focusing particularly on multimedia interactive services, TV, and Video-on-Demand.  The author looks at the IMS layer and how it interworks both downwards into the QoS-enabled IP transport layer and upwards to enable new kinds of applications. However, equal attention is addressed to the business models of players in the value chain, carriers, service providers, broadcasters, and production companies.

The author then examines how carriers have attempted to remodel themselves as IP companies along the dimensions of people, processes, and IT automation systems, describing the lessons to be learned from numerous failures. He identifies more innovativebusiness models, exploresPeer-to-Peer networking, and reviews the prospects for the introduction of spoken dialogue systems into the service provider’s arsenal of technologies.

Reviewing in detail the many failures and few achievements in carrier transition programs, the central theme of the book is how to organize for success. Business Strategies for the Next-Generation Network focuses on transformational business strategies for incumbent operators, alternate operators, and new entrants from the media world.

VoIP, VoIP, VoIP. These three letters are all over the place. They know that the acronym for communication and the computer is connected. You know, technology is the next "in" thing. But what is VoIP? And how can your business?

The Next Big Thing

The letters actually stand for Voice over Internet Protocol, sometimes called IP telephony. In a nutshell, is another way to make a call. Sometimes the phone is no longer available.E 'is particularly useful for long distance calls. The reason for the mass interest in this new technology is cost. VoIP may be cheap, but in reality, many people use to be viewed for free. All that is really needed is a microphone, speakers and a good Internet connection.

Tell Me More

What is VoIP? There is another way to make a call. But what good do you want? The first method is to have a computer at both ends of the call. L 'the second is a phone and a computer at one end to another you must have. The third is a phone at each end have the conversation.

What is VoIP? It 's a way to save on the organization of the telecommunications bill. This maximizes the existing infrastructure, without significant additional costs. VoIP transmits the received audio on the one hand on the Internet and converts the digital data back into sound at the other end. Seamless and efficient. Almost magical, too. In the end, you pay only your internet connectionAccount, as they use the same resources. Only this time, the resources are co-opted to carry voice and data.

What is VoIP? E 'scalable to your needs. Although it is essentially free access to the Internet, there are additional levels of VoIP, the cost of doing something. Use it with a normal telephone is one example. Use it with a mobile phone is different. However, this is cheaper than a normal call. And this is highlighted even morewith international calls. In fact, you can reduce their costs by more than 90 percent.

No Business Like Business Call

So what is VoIP? This is an exciting new adaptation of existing resources to reduce communication costs, and rapidly a broad consensus. There is much to improve, but it is a leading candidate to replace the normal telephone line. VoIP growth today is largely due to consumer awareness of manyAdvantages. This does not mean that there are disadvantages. Security is a central concern.

Nevertheless, the possibilities of VoIP are endless. It 's a great advantage for the company. In a competitive market of today, we can not communicate enough, and VoIP can reduce the associated costs. At the same time, it uses existing Internet investment company. It is also largely transparent to users who need a great thing to learn how not to reinvent the wheel.
