Frequently Asked Questions (FAQ)

What does viaGIA stand for?

The "GIA" means "Gigabit Internet Access". This name corresponds with the fact that all premises, in which viaGIA is offered, are connected using a multi-gigabit Ethernet network. This most extensive and state-of-the-art network in Prague now operates at a rate of up to 10 Gb/s.

The "via" means "way" in Latin, and at the time of Roman Legions it used to be the only fast and safe connection between two geographical points. This word appears in most names of transmission services provided by our company.

What is "symmetric" and "asymmetric" transmission?

Symmetric transmission means that both data flows – download (transmission of data from the Internet) as well as upload (transmission of data towards the Internet) are of the same speed. Although download usually forms approximately 70 - 80% of total data transmission, the proportion of the user’s line speed’s is not negligible. To what extent depends on the specific employed connection.

High-quality signal towards the Internet is important, apart from acceleration of regular browsing, in particular for any more serious work on the Internet (e.g. the so-called "home office" – work from home) and all interactive applications (on-line games, webcameras, exchange networks, telephone services via the Internet, chats, etc.). Asymmetric transmission, on the other hand, is useful for less demanding users who spend most time browsing on the Internet due to its price / performance ratio.

Where is the service available?

The service is available only in the selected premises in certain locations. The list of the respective locations is available here.

If the service is not available in your location and you are interested in a high-quality connection to the Internet, you can use our ADSL services.

What do I need for viaGIA?

For the purpose of viaGIA, only a personal computer is necessary. It needs to be equipped with the Ethernet LAN interface (connector RJ 45). At present, the Ethernet connection is mostly integrated in the motherboard of your computer.

It is possible to operate all operating systems with implementation of the IP protocol on the connected computer - typically the Microsoft Windows family (ranging from WIN 95 on), in addition, for example Linux, MacOS, QNX, etc. On the computer, it is necessary to activate the DHCP function (automatic allocation of an IP address) and the automatic configuration of the LAN interface rate (the so-called autodetect). In Windows, these two parameters are set as default values under standard settings. A detailed procedure for possible DHCP function setting is available in the instruction manual for the service. If your viaGIA connection is functioning duly, there is no need to set anything.

If you wish to connect several computers, it is possible to use a home router / a switch. This possibility is applicable to all variants of the service. Use of several computers is allowed only within one apartment, the service shall not be shared outside the respective apartment (neither in return for payment nor free of charge).

What are transmission rates and variants of viaGIA on offer?

At present, the service is provided in three transmission rates (tariffs). The Light variant offers asymmetric connection at a rate of 15 / 5 Mbit/s, the Comfort variant provides for symmetric rate of 30 Mbit/s and the highest variant of the service is represented by the Ultra rate amounting to 100 Mbit/s in the asymmetric mode.

All rates of the viaGIA service are subject to the payment of a flat rate, regardless the volume of transmitted data.

Are rates (speeds) of viaGIA guaranteed?

The viaGIA rates are not guaranteed, these concern the highest rates (speeds). Both access and backbone networks are owned directly by T-Systems, thus no significat difference between nominal and real speeds appear.

What does viaGIA enable?

Technically speaking, it is possible to use all standard protocols - HTTP, FTP (in passive as well as active modes), DNS, ICQ and others. In practice, this means a wide range of use, such as browsing on the Internet, downloading files (video, music, graphics, etc.), on-line communication in real time – games, chat, voice, electronic mail to mention just a few.

What does the viaGIA service include?

  • Fixed connection to the Internet using the viaGIA technology
  • Allocation of mail box in the domain, accessible through POP3, IMAP4 or web interface
  • Information and technical support from our Contact Centre

The instructions for the mail (e-mail) client – POP3 and IMAP4 setting, are available in the instruction manual for the service.

Can I use viaGIA together with a telephone line (the viaPhone service) for telephoning?

Yes, it is possible to use the line fully for both telephoning and faxing while operating the viaGIA service. Both the services are independent of each other.

What are conditions for the use of an IP address in case of the viaGIA service?

As a standard, the viaGIA service is allocated a public dynamic IP address. This address is allocated to the customer using the DHCP function. In case of interest, it is possible to order a fixed IP address.

Can I connect several computers to viaGIA?

Yes, it is possible. For the purpose of connection of several computers, it is necessary to employ a router. Apart from interconnection of the computers, such a router may work as a firewall. Modern routers offer wireless interconnection of the computers (Wi-Fi, etc.). This option is available for all variants of the service. For further details see the Supplementary devices.

Several computers also mean a more extensive sharing of the line capacity and it is therefore advisable to use the variants offering higher transmission rates.

Use of several computers is allowed only within one apartment, the service shall not be shared outside the respective apartment (neither in return for payment nor free of charge).

What terminal devices are used in case of viaGIA?

The only terminal device, in the true sense of the word, is the data socket in the wall of the user’s apartment. The customer does not need any external device. The only thing the customer must do is to insert the cable into the computer and to switch it on (after the service has been activated).

An optional device is the so-called home router (residential homegateway) enabling to connect several computers to one socket or to operate several different services belonging to the viaHome family (Internet, cable TV, telephone) using one socket. For further details see the Supplementary devices.

How are the viaGIA services charged/billed?

The services are billed once per month, always to the end of the respective period. You pay a fixed monthly flat fee according to the selected tariff, regardless the time spent on-line, number of log-ins/log-outs nor volume of transferred data.

Methods of payments for the viaGIA, viaPhone and viaTV telecommunication services

The viaGIA, viaPhone and viaTV may be paid using either of the following methods:

  • 1. Repeated payment by collection from an account (recommended method of settlement)

For this payment, it is necessary to arrange for the so-called collection order (encashment – in Czech "inkaso") in your bank allowing T-Systems to collect money for the provided services from your account. Further on, everything proceeds fully automatically and you do not have to care any longer. Within the collection, it is possible to determine the so-called collection limit – a maximum amount, which may be collected on a lump-sum basis within the framework of the respective collection payment (be careful about collection limit concerning payments in case of variable monthly amounts, such as telephone services).

Upon payment via collection, it is necessary to do the following:

  • Fill in your account number in the Contract, to the debit of which collection is to be performed
  • Arrange for the collection order in your bank and allow for collection to the credit of the below-mentioned account of T-Systems
  • Do not fill in variable symbol (it is used as an identifier of the payment)
  • Make sure that to the date of maturity (the 14th day in the respective month) there is sufficient balance on your account, to the debit of which collection is performed, so that collection may be executed

This form of payment releases you from the duty to watch the oncoming date of maturity every month and at the same time, you do not lose control over sums, which are to be withdrawn from your account automatically.

Bank details of T-Systems (applicable to both lump-sum direct payments and for collection):

Account name: T-Systems Czech Republic a.s.
Account number: 1905602
Bank code: 0800

  • 2. Lump-sum payment

Upon receiving the invoice, you perform a lump-sum payment, either electronically or in person at your bank. The number of the invoice is to be used as the variable symbol; you should not round the sum.

The method of payment shall be selected beforehand in this Contract. In the course of validity of the Contract, the method of payment may be changed upon agreement with the Provider.

Unfortunately, it is not possible to perform payment by arrangement of a permanent payment order (the variable symbol serves as an identifier of the payment period – it is changed every month). In this case, it would not be possible to identify the incoming payment and you might be unjustly identified as a defaulter. Therefore, we would like to ask you not to arrange for a permanent payment order for payments concerning services provided by T-Systems – this will help you avoid problems with missing or delayed payments.

The service does not function duly

It is necessary to realize that the connection to the Internet as such is only one link of the entire chain. The chain consists, on the one hand, of a computer, in which the main role is played by the network card and by the motherboard, the RAM and the optimally set operating system and the www client. As it follows from experience, not every average, in a household used computer is able to reach the port rate of 100 Mbit/s.

Even a more limiting key factor is the connection of the counterpart – the server (the computer), to which you are connecting – the rate of its connection. This rate is limited by the weakest link of the chain and if the computer is located somewhere abroad, such a "chain" may be several thousands miles long and formed of many networks of a wide range of providers and many different technical elements (routers, switches, …), where the respective rate may reduced and delayed. Moreover, an important role is played by the quality of the server as such and in particular by the number of users with whom you are sharing the server at the moment.

These numbers may reach thousands of users at the same time, as well as the numbers of users sharing certain sections of the network.

On the Internet, there are various measuring instruments, the accuracy of which however may be misleading – during practically every measurement you will get a different result due to the above-mentioned reasons. Problems arise in particular upon measurements performed at higher rates.

What is the length of the period, for which the contractual relationship is concluded?

The contractual relationship is concluded both for a defined and an indefinite period of time, for further details see the current version of the Contract and Business Terms and Conditions.

How long does it take to install the service?

The service is usually installed within 14 days as from the date of receipt of the signed written Contract. In most cases, the installation id faster, approx. 1-2 working days unless some technical problem comes up. For activation of the service there is no need to enter the customer’s apartment.

What does the certificate stand for and what is its importance and purpose?

The personal certificate is an electronic variant of the personal proof of identity (the electronic ID), by means of which its holder proves their identity in electronic communication (with authorities, banks, companies, ...). The certificate identifies its holder unambiguously and in case of the viaHome family services it is used for the purpose of safe log-in to the Portal with personal data relating to provided services, to the allocated e-mail box and for a secured communication with T-Systems Czech Republic a.s. as far as all aspects of such communication are concerned.

The personal certificate is nothing else than an electronic file, which may be saved either on the computer or better, to prevent possible misuse, on a portable media (a diskette, CD, memory card, USB key case, …). The certificate (the media, on which it is saved) shall be protected against misuse (a theft) as another proof of identity. In addition, the Certificate shall be protected with a password.

The validity of the personal Certificate is 1 year and then it is necessary to extend its validity.
The first issue and prolonging of the personal Certificate is free of charge.

Reference to the Certificate is provided via e-mail. Subsequently, it is sufficient to install it in accordance with the attached instructions in your browser.

It is also possible to use the existing own certificate, if it was issued by a certification authority acceptable for T-Systems:

  • CA 1.Certifikační
  • CA KB
  • CA T-Systems Czech Republic
  • CA stated in the current version of MS Explorer

In the room where I wish to use the service, there is insufficient number of telecommunication sockets.  What shall I do?

For each socket connected directly to T-Systems it is possible to order and to operate all the viaHome services (viaGIA / viaTV / viaPhone) at the same time on condition that you adapt the socket using the so-called home router (homegateway). This function, implemented since autumn 2008, is called OnePort and you may find more information on it in the Documents for download section.

I would like to learn more about telecommunication distribution frames in my apartment. Where shall I get such information?

General information on distribution frames are summarized in the "OnePort – multiple services on one socket" document. If your apartment is equipped with a home distribution box for telecommunication service as well, we recommend you to read also the "Home distribution box for telecommunication services". Both the documents are available in the Documents for download section.
