Electronic data collection (ESD)
The applicant for access (authorised person) shall fill in an application for access to the ESD system which can be found on ESD homepage.
The completed application for access to the ESD system in PDF format must be downloaded and delivered via data mailbox, by authorised email, post or personally to the CTU. Addresses with contact details are here.
After receipt of the application by CTU, access to the ESD system will be activated for the authorised person who will be informed about it to the e-mail address indicated in the application for access to the ESD system, or by SMS message if they choose this method of communication in the application.
In the ESD system, after activating access, the authorised person can create and subsequently administer the access for up to 3 designated persons, who can only fill in and submit the forms. More detailed information incl. instructional videos about the ESD system can be found on the ESD homepage.
Login to the ESD system is possible only through the Citizen Identity Portal for citizens of the Czech Republic and for citizens of countries that have implemented Regulation No. 910/2014 of the European Parliament and of the Council (EU) of 23 July 2014 on electronic identification and trust services for electronic transactions in the internal market and repealing Directive 1999/93/EC (eIDAS Regulation).
In order to successfully log in to the ESD system, after being redirected to the Citizen Identity Portal (from the home page of the ESD system), it is necessary to give consent to the use of identification data (in the case of citizens of the Czech Republic, at least surname, first name, document number and type of document or surname, first name, date of birth and address of permanent residence).
Citizens of states that have not implemented the eIDAS Regulation log into the ESD system using a username and password.
Logging into the ESD system via electronic identity verification (Citizen Identity Portal) must be initiated on the homepage of the ESD system by pressing the "Log in" button. You will be redirected to the Citizen Identity Portal and shown the selection of login options (e.g. eGovernment mobile key, eObčanka or bank identity). Difficulties may be caused, for example, by accessing the ESD website from a saved bookmark. The best browsers to use for logging in are Google Chrome, Mozilla Firefox or Microsoft Edge (or the latest version of MS Internet Explorer). For MacOS, it is not recommended to use Safari browser. Before attempting to log in again, it is advisable to delete cookies and temporary internet files in the browser or open the browser in a new anonymous window. At the same time, it is recommended to check whether browser/computer protection such as Kaspersky Internet Security, BitDefender, etc. is running; in some cases, disabling it may help.
If problems persist, you can contact Citizen Identity Portal support or directly your identification device provider.
If login issues with the ESD system occur after verification and approval of identification data via the Citizen Identity Portal, you can contact CTU staff at monitoringtrhu@ctu.cz and attach the copy of the error screen and the date and time of the failed login.
Red-highlighted fields indicate an automatically identified logical error in the data filled in the form. Further information or description of the error is given in the warning that appears in the right part of the form in the box marked ERROR after clicking on the red-coloured field. The setting of error indications is based on the most common cases of form completion. For this reason, there may be situations where, in specific and justified cases, the form will be filled in correctly even if an error is indicated. In these cases, the form can be submitted with the red-highlighted fields, but it is necessary to provide an explanatory note at the end of the form, e.g. the specifics of the services provided or the business model, etc. The first time the form is submitted, the ESD system will return the form for correction or completion based on automatically identified errors (red-highlighted fields). If this is a justified case (see above), it is sufficient to add an explanatory note (if the form does not already contain such a note) and resubmit the form.
Yes, the obliged person shall fill in the form even if they have terminated or interrupted their business in the reference period. For this purpose, the obligated person will be assigned a specific so-called extraordinary form at the moment when CTU learns of the termination or interruption of the activity, if the termination or interruption occurs in the period from January 1 to October 31 of the relevant year. Thus, the obliged person does not have to wait for the assignment of the standard form (for the first half of the year and for the whole year) and fulfils their information obligation towards CTU already at the moment when they complete and submit the assigned extraordinary form. The extraordinary form contains only flow variables, which distinguishes from the regular form. However, this form retains all the functionalities of regular forms and is also used in the same way within the ESD system (i.e. it is filled out, submitted, checked, returned for correction or completion, etc. in the same way). If business activity is interrupted or terminated between 1 November and 31 December of a given year, the obliged person will be assigned a standard year-long form, which contains all monitored indicators, at the beginning of the following year. However, in this assigned form, an obliged person that has terminated or interrupted their business activity shall only fill in the flow variables (e.g. number of minutes, revenue for voice services, and revenue for data services) cumulatively from the beginning of the reporting period to the date of termination/interruption of the communication activity and submit the form in the ESD system. A special form will not be assigned to the obliged person in this case. If the obliged person did not provide any services or networks during the reporting period, they may submit the form with blank fields (it is not necessary to fill in zero values in individual fields), but before submitting the form, they must tick the reason “We have terminated/suspended the provision of services in the above section” for each unfilled section from the list of reasons for not filling in sections of the form.
The columns with indicators on the address points covered by the disposable connection are filled in by the obliged person providing the electronic communications network, i.e. the operator of the relevant infrastructure to the network termination point (the point where the internet access service is provided to the subscriber - end user (at retail)), regardless of whether this obliged person provides retail services or not. Therefore, the obliged person shall complete these columns even if they only provide the network to other service providers at wholesale level.
Note: Although the obliged person is usually the owner of the infrastructure, this may not always be the case. The person providing the network may not be, for example, a municipality that owns the network, but it is operated by another person (the network operator) who actually maintains and uses it for the given purpose. In this case, the infrastructure data is not filled in by the municipality (i.e. the owner), but by the network operator.
The columns relating to the services provided, i.e. accesses (active connections), on which the service to the subscriber – end user is provided are completed by the provider of the internet access service to the end-user, regardless of whether such a service is provided through own infrastructure or the infrastructure used on the basis of a contract with another undertaking operating the network.
In most cases, the obliged person is both the network operator and the service provider. In this case, they will fill in both information on accesses (active connections) and data on the address points covered by disposable connection.
A covered address point is an address point at which the obliged person operates or is able to complete at least one disposable connection.
Disposable connection is:
- a connection installed at the end-user's premises (whether or not the service is provided through it), i.e. an existing connection, or
-
a connection which has not yet been effectively installed but which the obliged person is able and willing to establish and provide a service of the relevant parameters on it, provided that all of the following conditions are cumulatively met:
-
there is a commercial offer of internet access service at the address point corresponding to the relevant declared connection parameters;
-
he obligated person is able and willing to establish a connection at the given location corresponding to the relevant declared parameters and to provide the corresponding internet access service within four weeks after the subscriber's expression of interest, without any charges for the establishment of the connection and putting the service into operation exceeding their normal amount;
-
if it is necessary to install a connection (set up a connection), this must be done without incurring disproportionately high costs;
-
disproportionately high investment costs: e.g. extensive excavation or construction of masts;
-
examples of reasonable costs: installation of wiring in a residential building, ensuring installation of terminal equipment, strengthening the capacity in the last terminating segments of local loop, e.g. by replacing active network elements
-
-
if, in addition to the connection itself, a distribution point located at the same address point as the disposable connection, or in close proximity to it (in the order of metres), must be established in order to provide a service of the given parameters, when listing covered address points with disposable connections, the obliged person may also take into account this yet non-existent distribution point, provided that it can be constructed under the above conditions. Other distribution points and other parts of the connected network must be available at the time of data collection, i.e. constructed.
-
It is essential for the reporting of the parameters of disposable connections that the obliged person is able to ensure the quality of the service simultaneously at all covered address points listed in the geographic data collection (considering the technological capability and available bandwidth of the technologies). The available capacity in connected parts of the network should be available at a given time, respectively can be increased operationally without constructing entirely new network components. More detailed information is available on the CTU's website and in the guidance included in the annexes for the geographic data collection.
The definitions and parameters for Very High Capacity Networks (VHCN) are based on Directive (EU) 2018/1972 of the European Parliament and of the Council of 11 December 2018 establishing a European Electronic Communications Code (Article 2(2) and Recital 13) and on the related BEREC Guidelines on Very High Capacity Networks of 5 October 2023 (BoR(23) 164). These Guidelines, including its non-binding Czech translation, are also available on the CTU´s website.
In context of these documents, connection via VHCN networks is divided into fixed and wireless, whereby fixed connection in relation to VHCN means connection over networks that use metallic (including coaxial) and fibre transmission media for data transmission.
VHCN network means, in the case of a fixed connection (FTTH/B, xDSL, CATV):
a) a network consisting entirely of fibre up to the building – VHCN category 1,
or
b) another fixed network capable of providing at the network endpoint a 'downlink data rate' ≥ 1 000 Mbit/s, an 'uplink data rate' ≥ 200 Mbit/s, a packet error rate of max. 0.05 %, packet loss rate max. 0.0025 %, bidirectional IP packet delay max. 10 ms, delay variation max. 2 ms and service availability of at least 99.9 % per year – VHCN category 3.
Performance thresholds are based on the data rate at the transport layer protocol payload level for downlink and uplink (layer 4 of the ISO/OSI network model).
In the case of wireless connectivity (typically wireless access in licensed bands and wireless access in free bands), a VHCN is:
a) a network consisting entirely of optical fibres up to the base station (or similar wireless access point (AP), i.e. a point with active communication equipment for broadcasting, transmitting and routing traffic to and from the end user) – VHCN category 2;
or
b) another wireless network capable of providing a downlink data rate ≥150 Mbit/s, an uplink data rate ≥50 Mbit/s, a packet error rate of max. 0.01 %, packet loss rate max. 0.015 %, bidirectional IP packet delay max. 18 ms, delay variation max. 5 ms, and service availability min. 99.9 % per year – VHCN category 4.
Performance thresholds are based on the data rate at the transport layer protocol payload level for downlink and uplink (layer 4 of the ISO/OSI network model).
Where a wireless connection meets the 'more stringent' criteria of VHCN category 3, primarily intended for fixed-line (cable) connection services (metallic and fibre transmission media), such a network is reported as a 'fixed VHCN' of VHCN category 3.
If the address point is covered by a VHCN network, the obliged person shall select the appropriate VHCN category (1 to 4 or the appropriate 'VHCN category code') for the record.
In case of simultaneous fulfilment of the criteria of several VHCN categories, the obliged person shall proceed as follows:
- if they meet the parameters of VHCN 1 and VHCN 3 in the case of a fixed-line connection, they fill in the VHCN category 1.
- if they meet the parameters of VHCN 2 and VHCN 4 in the case of a wireless connection, they fill in the VHCN category 2.
- if they also meet the parameters of VHCN category 3 in the case of a wireless connection they fill in VHCN category 3.
Note: The terms downlink and uplink data rates represent network parameters in terms of downlink and uplink data rates, The potential ability of the network to provide a service with the relevant quality parameters at the terminal point without the service having to be actually provided or offered at the time of reporting is crucial for determining the appropriate category given the performance parameters (Category 3 and 4).
