Does it make sense to change TDM to IP?

 IP-technology approved by the communications market stronger with each passing year. Already no one doubts that the future belongs to IP networks that will keep pace with the ever-growing needs of network users, as opposed to TDM networks that already today are outdated. Is it possible to “painless” transition, we consider in this article.

Some experts believe that the TDM network is no future. Yes, they debugged, well-organized business processes and more. But today, almost all telecom operators are engaged in the universal service and at least provide more access to the Internet. Telephony pure and Internet services – a different network infrastructure that needs to be maintained in parallel. Each of them is costly, which affects the monthly fee, the competitiveness of the company and place in the market. Since communication services can already provide means of VoIP, ie via the Internet, over time telecom operators abandon traditional telephony, replacing it with the IP-telephony.

Understanding what the future will completely replace traditional telephony to IP is at all, but not all operators are in a hurry to abandon the TDM networks. The fact that the demand for IP telephony is growing in the corporate sector. However, end users are in no hurry to move on VoIR, because for them the main thing – a stable simple telephony. Therefore, the operators, which is important audience of ordinary users, while trying to keep this segment of the market.
IP telephony is not requested in the general population due to low information content of these services, and low pay.

If you connect to analog telephony services, relatively inexpensive (about 80 USD), then connect the IP-phone itself will be more expensive. Of course, the versatility and ease of use is superior, yet the price of the connection for the casual user is often the deciding factor.

One of the alternative ways of development of IP-telephony is the construction of NGN. This converged next-generation network, which is widely popularized manufacturers Architecture IP Multimedia Subsystem (IMS). Using the network effectively reduce the cost of operation, offers a range of services and earn more money. But since that is not a standardization of IMS, each manufacturer offers its platform.

What need to be

Experts point out that, sooner or later, the operators no longer just TDM limited to simple functions, and want to expand their list of services due to IP telephony. After all, the use of such services is the key to saving the business and their income. In traditional telephony the main profit comes from the number of seconds or minutes. In the IP telephony companies will make a number of bytes transferred, connect to the Internet and other services. To the company did not have to choose between TDM and IP networks, there are special gateways TDMoIP, which allow you to provide IP telephony services based on TDM networks. Such TDMoIP gateway from Terratel will significantly reduce operating costs, increase revenue from new services, as well as move to new networks with minimal changes in equipment.
