Telefonica will use a German provider of network services for internet

The Spanish telecommunications company Telefónica will enable the German provider 1 & 1 Internet using its infrastructure in Germany to offer combined services and internet telephony.
Telefónica Germany reported today that 1 & 1 Internet connection will provide a complete telephone and internet browsing through the net of the Spanish company in this country so that their customers do not need a telephone connection added.

Telefónica Germany and 1 & 1 Internet cooperating since 2005 in offering phone calls over the Internet, the installation of speed connections to the network and the distribution of video on demand service Maxdome, the German TV company ProSiebenSat.1.

The director of Telefonica Germany, Johannes Pruchnow, said that with this agreement "we confirmed our strategy to invest heavily in one of the most modern networks, and more future in Germany."

The spokesman for 1 & 1 Internet, Andreas Gauger, believes that "Telefónica's infrastructure is the basis of our full internet connectivity and telephony, we want to reach more than 60 percent of German households in the future."

Services Provided In Internet Telephony

All Phones Internet can provide the same services, because they use about the same technology, but business reasons, or technological development, mark significant differences between different providers.When it comes to deciding which Internet Phone, is essential to make the comparisons necessary to make a decision.

Hardware:
Special hardware equipment is not essential and you can access the service with a good computer, a headset with microphone and a good banda ancha.
To begin, you do not need more.
If they determine to a significant initial investment, dude, or checking the service ask another user, and compare it with that you can receive without these facilities.

Turnover:
This theme, seemingly unimportant, is also vital.
Most providers is unable to issue invoices with VAT discriminated. And if your company consumes about $ 200 per month in telephony this can mean a loss of tax credit exceeding $ 500 annually, which is not little.

The Customer support:
Check. A communications provider must be able to meet customer service that promises (either high or low) and if you can not satisfy it is because their infrastructure is not adequate and you could face problems if the contractual services.

Access from the traditional telephony:
If you acquired an Internet telephony service, which can be use to call it from the main cities of the world, from telephone, paying local rates.
And the process should be simple. Dial and conertarse. From a phone. But DO NOT sit at a computer, enabling software, register, and pray that at the other end connected also to speak. Because that is not Internet telephony, but voice chat.
Internet Your phone should have a number that can be dialed from any traditional phone.

The Voice Mail:
One of the most beautiful treasures of the Internet telephony is the Voice Mail or Voice Mail
If you are not facing your Internet phone to serve you, you can leave a voice message, as in traditional telephony, but it arrives at your mail box almost instantly ... and, if desired, can receive an alert tone, in text format in the mail box of your cell phone.
This service is free in most of the suppliers. But check, because some providers advertise the free service but charge a voice mail. And not little.

The free calls to other networks:
Internet telephony is a network such as the Internet itself. And allows for free calls between the networks of 300 internet phone service. If your provider does not offer this alternative because it is not linked to other networks and their performance will be limited.

Internet Service Providers

Internet connections can be classified according to their speed (bandwidth), the connection type (permanent or temporary) and the physical environment and type of connection (fixed or mobile telephone, ISDN, ADSL, fiber optics ... ). Different combinations of these three parameters determine the connection speed, the price of the service and the services we can assemble.
Connection speed and transfer rate

Internet is a network of data transmission, and thus the connection speed defines the speed of access to their services. The transfer speed is measured in bits or bytes per second, with corresponding scale factors (k = 1,000, Mega = 1,000,000, Giga = 1,000,000,000).
In connection speed must differentiate between the maximum speed of the means by which we connect (connection speed) and the maximum speed of data transmission that provides the service provider.
To communicate with another system, the transfer speed depends on connection speed of each state and all intermediate systems and networks that data must traverse to get from one end to another.
The speed at which we receive the data (transfer rate) changes every time, depending on the state of the network, the ISP provides the service, the number of simultaneous users of the provider of the computer ...
In the case of working from a local area network, we must also distinguish between the speed of connection to equipment and the network connection speed through the Internet connection you have with our organization.

Permanence of the connection

Standby, we refer to the necessity of conducting an operation to provide connection.

1. Permanent connection: a firm or organization contracts with a communications provider (Telefonica, BT, Jazztel ...) a link connected to the Internet. In this way, a network of computers can get all your equipment is permanently integrated into the Internet. This is an expensive solution, to which must have special equipment for communications, but provides higher transfer speeds, and allows its use is shared by more users.

2. Temporary connection in this case, access is contracted with a provider of Internet connection (Teleline, Mundivia, Jazztel ...), which is active only during the time that we make the call. It is oriented to individual users, using a personal computer and a modem, using the basic telephone network (ISDN or if they want better benefits), to establish communication with your provider, and through him, with the Internet.

Almost all providers offer flat-rate connections, ie pay a fee for the connection, regardless of the duration.

The connection is essential if we are to mount an Internet service visible from the outside (eg the website of our company), meaning that other users can access one of our systems regardless of the state of our network or when the day.

Temporary connections used a protocol called PPP (Point to Point Protocol) which is responsible for validating the access name and password) and share any information with our supplier.
Medium Connection

The most common are:
Copper telephone wiring, which can use a standard modem (up to 56 Kbits), an ISDN modem (two lines of 64 K) or a DSL modem (from 256 to 1.2 Mbits).
Coaxial cables or twisted pair, typically used for local area networks (10 or 100 Mits). Also use the metropolitan cable networks, such as ONO.
Fiber optic networks for greater scope in that it allows connections to more speed and greater distance between links.
Price Connection

In the case of permanent connections, the price of the connection depends on the bandwidth requirements (the maximum speed that can communicate via the link, guaranteed minimum speed). Normally you pay a monthly fee for the concepts of physical connection and data flow hired.

Should go to the web pages of information for each provider to learn of the various bids in force in each case.
Supplier Connection

Are companies that provide Internet access. Until recently, it was necessary to pay a monthly fee for access, but today many of them give us free internet access, pay only the telephone call (also offer other services such as email address, space for publish web pages, discussion areas ...).

You can learn how to connect to the following Web addresses:

• JAZZTEL
• ONO
• ORANGE
• TELEPHONE
• TELE2

Elements for the connection
1) Computer and operating system

To connect to the Internet, we need an operating system that provides communications software (TCP / IP, PPP dialup, ...); All versions of Windows, Macintosh and Linux have all the necessary elements to connect, although Linux is a little more complicated by the characteristics of the operating system (however, is the fastest and most efficient of all).
2) Modems

There are two types of modems in terms of its connection to computer, internal or external. The first space-saving and cables, it is only necessary to connect a computer to the phone. However, they may be more complicated to connect and configure because it is necessary to open the computer and available hardware resources (IRQs. ..) for operation.

External modems connect to your computer using a serial port, so its setup is simple and easy to share among multiple computers. But more is needed cables (telephone, computer and power supply).

If basic telephone network connection settings must be at least a 56K modem supports the V.90 standard, approved by a communications company (Telefónica) and ability to update their firmware (the program that operates the internal modem ). In this way we ensure that we can update it in the future.

For ISDN or ADSL modems, the connection will be the provider that we recommend an approved modem.
3) Applications

Each Internet service is an application 'client' which allows to collect data and display them. For example, to visit the many websites available on the Web requires a browser such as Internet Explorer, Netscape Navigator, Opera, etc ... For all Internet services, there are many versions of clients, free of charge (freeware) assessment must then be paid (shareware) or to pay.

Operating systems Windows, Mac and Linux installed bring more current versions of the most common applications (web, ftp, telnet, irc) so it would be possible to start work immediately. The following directions allow you to download updated versions of almost all the tools.
