Frequently asked questions

The SIP Trunk is a virtual channel that enables setting up phone calls via Internet links. It provides freedom in terms of telephone network configuration, adding services, transferring numbers or controlling the costs. This very protocol enables calling landline or mobile phones via the Internet.

Yes, it is possible, although it depends on the assumed service parameters. Contact us and, based on detailed guidelines, our team will conduct an analysis to confirm the feasibility of providing the requested SLA.

You can order services provided by EXATEL by contacting us via the contact form on the website, e-mail bok@exatel.pl or via phone: 801 27 10 44.

Yes, the report provided as part of the service contains the necessary information to directly improve security.

The customer receives their report approximately a week after the work is completed.

No, the goal of Reconnaissance is to provide measurable results in a short period of time based on selective security verification.

TAMA is a scalable and powerful operator-grade service solution that provides comprehensive protection against DDoS attacks. It is the only solution of this kind in Poland, tailored to the needs of a telecommunications operator. The service is available in several options, depending on the customer's needs.

We are a State Treasury Company. We protect critical infrastructure (military, police, government institutions, medical services, etc.), so we know the importance of data quality and protection. We are both an operator and a leader in cyber security. Additionally, in 2021, we opened our own teleport and started to provide satellite services.

Our company offers a wide range of professional cyber security services. Exatel’s key services include: monitoring and incident handling by Security Operations Center, antimalware protection, data leakage protection (DLP service), penetration testing, security audit and our proprietary DDoS attack protection system – TAMA.

Cybercriminals' methods to hack companies' systems are becoming increasingly more complex. A successful cyber attack can have a serious impact on business continuity. For example, criminals can lock down all company computers, halt production processes, and even steal company customers sensitive data.

The value of data the company is obliged to protect is much higher than the cost of a security audit. In addition, companies are required to conduct periodic security audits or penetration tests.

Penetration tests should be performed when:

• relevant data (e.g. personal, medical, payment card data) is processed by a web app,
• a significant part of the company's business is based on web apps made available on the Internet,
• the value of the protected data significantly exceeds the cost of the audit and other security measurements applied,
• there is a suspected breach of application, infrastructure or data security,
• your company wants to minimise the risk of an attack on IT resources,
• your company is obliged (by law, internal procedures, etc.) to periodically conduct security audits or penetration tests).

Penetration tests consist in conducting a controlled attack on the client's IT systems. It allows for practical assessment of the current state of the company's security.

Penetration tests are implemented in three variants:

• blackbox (the tester is not equipped with any knowledge about the system under tests),
• graybox (the tester has limited knowledge about the system under tests),
• whitebox (the tester has access to all information about the system under tests).

Disclosure of this type of data can expose a company to criminal, civil and reputational liability. A data leak would also mean a number of unplanned expenses for the company related to: identifying victims, informing those affected by the data leak and the need to provide them with certain services, PR activities, legal services, loss of customers (and issues connected with acquiring new ones) and loss of reputation.

Data leakage means an unauthorised disclosure of data outside the company through a theft or unintentional action of the company's employees. This data contains information that is protected for business (business secrets) or legal reasons (personal, sensitive, financial and medical data).

EXATEL's antimalware solution is a comprehensive protection of customer’s IT resources against known and unknown malware. The service is provided on a central platform located in our Data Center and on the customer's devices. We provide the service on the Elevate XDR platform from Fidelis Cybersecurity.

The impact of malware on one's computer can range from displaying unwanted ads (adware) and taking over computer cameras (camjacking) to locking computers for ransom (ransomware). It may happen that infected computer becomes a part of so called botnet and participates in DDoS attacks without the knowledge of its owner. Some malicious codes can steal data and lead to reputational or financial losses for the company.

The first step taken in order to create/modify a process protecting an organization against cyberthreats should be a security audit. This allows the drawing up of a map of security vulnerabilities and threats, including their assessment and recommendations for remedial actions. Starting the process by merely investing in a security system is a mistake. It entails a risk of inadequate or unnecessary costs and time loss.

Yes - one of the service deployment variants enables protection when using the line of another operator.

TAMA is an operator-class solution that is scalable and provides security up to 80 Gb/s. It can be used in combination with a smaller system installed at the customer’s premises - or instead of expensive, foreign operator solutions.

Over the past few years, data security and personal data security (in particular) have become a priority. Therefore, GDPR was added to such applicable standards as ISO/IEC 27001, ISO/IEC 27032, PSI-DSS. It should be recognized that a potential leak can even lead to insolvency, regardless of its volume. This is why this threat, no matter the extent to which your organization uses IT solutions, should not be underestimated.

Malware is the general name covering broadly understood malicious software that is harmful to a digital device user. Malware types include viruses, worms, Trojan horses, backdoor, exploits, rootkits, key loggers, ransomware and many more.

Using your own Security Operations Centre is much more expensive than utilizing professional sourced services. This is mainly due to the high entry barrier, but also large running costs. If the core activity of (even a large) organization is not cybersecurity, it will be difficult to achieve a service quality guaranteed by EXATEL at a similar price.

The Security Operations Centre is the only service that combines continuous (24/7) event monitoring with the knowledge and experience of professionals who are able to quickly identify and appropriately respond to incidents.

Certainly not. SOC services include a whole range of products, some of which are intended for small and medium-sized organizations with lesser resources. In the course of initial meetings, our team will help you choose the best solution for your organization.

Cybersecurity is a process and an investment at the same time, the return on which is often hard to show within an organization. The SOC Starter service can be a solution to this issue. The efforts of our specialists give IT managers specific arguments for discussion – we provide a map of threats and a plan for further, potential actions, facts, numbers and examples. They facilitate convincing Board Members to invest in a security system for the organization.

ARFA is the continuation of the TAMA project - it is a set of additional modules that can be used to equip the TAMA anti-DDoS solution. Owing to new techniques added in the field of DDoS attack detection and mitigation, ARFA enables preventing, among others, new volumetric attacks.

The service is priced per line.

Yes. You will have a client portal at your disposal with presented information on alarms and implemented mitigations that are actions aimed at preventing or eliminating attack consequences.

The recent years have seen large corporations, as well as local government units, non-government units, associations and small-sized enterprises fall victim to attacks. The ease of conducting such an attack means that no organization is too small to be affected.

Ordering the service is quite simple. The order should indicate the basic parameters, i.e.:

• the desired connection region,
• public cloud provider,
• bandwidth value.

On this basis we will prepare the most suitable offer.

A customer of the Cloud Connect service can be any organization that uses resources within the public cloud, i.e.:

• public sector organizations (including local government),
• enterprises of different sizes (SMB+LE),
• small and medium-sized companies,
• financial institutions.

The Cloud Connect service operates at Layer 2 of the ISO/OSI model. EXATEL is not involved in Layer 3 configuration. BGP/IP sessions are set up directly between the Customer and the cloud provider – the Customer sets them up themself in the customer portal of the selected provider.

The minimum number of licenses for the first order is 100 accounts. Each subsequent order can be placed for any number of licenses.

Yes, the solution was created with remote work in mind. When using this tool, the user feels as if they are working at their computer in the office.

No, all you need is a device (computer, tablet or smartphone) with internet access. With Virtual Desktop, an employee will have access to all documents, applications and internal systems of the company from any device, regardless of the place.

Yes, because the solution uses several security features including, among others,: two-factor authentication, watermark (“sealing” a session against manipulation), extensive security policies, access encryption or integration with the customer's Active Directory. Additionally, the data is stored in EXATEL's Data Center in Poland.

Persons or institutions requiring stable and secure data transfer may be recipients of the service, i.e:

• companies and corporations
• public and government administration bodies,
• non-governmental bodies – for example schools, universities, cinemas
• Internet network operators

Most companies that offer similar services operate locally in a designated area. Customers with extensive networks would have to sign separate contracts with subcontractors operating in a given area. EXATEL's infrastructure maintenance service covers the entire country. We are always on standby and our specialised service technicians begin repairs immediately after receiving information about the damage to the fibre-optic cable. We are one of the few companies in Poland that hold an industrial security certificate and most of our employees have clearance for access to confidential or secret information.

The service can be used by both telecommunications operators and public sector entities, including but not limited to: cities, border guards, police and military networks.

This service consists of providing and maintaining a wireless local area network using Wi-Fi. WLAN is designed to provide the best signal coverage and capacity in a secure manner and guarantee protection against unauthorized access.

WLAN offer is addressed to various industries, in particular to companies that rely on free communication of their employees and to administrators of public space wishing to increase its attractiveness.

First of all, the service will increase the level of web applications cybersecurity without the necessity to invest in hardware and workforce. Additionally, WAF protects against 0-day attacks, bruteforce attacks, and those listed in the TOP 10 OWASP (Open Web Application Security).

WAF allows you to control traffic in two ways:

• Creating a blacklist that defines a list of dangerous content that, depending on the configuration, will be blocked, changed, or noted in the logs,
• Creating a whitelist that defines a list of accepted content.

The WAF service allows you to create security policies which are built on the basis of rules that block or allow a specific type of Internet traffic.

The unquestionable benefit of the Managed Firewall service provided by EXATEL, which is monitored 24/7/365, is that it ensures secure communication via the Internet and protects the IT infrastructure against various threats; in addition, we guarantee full support of our experts at all stages of the service.

It is a solution that provides comprehensive security of the client's IT resources using a firewall. Using Unified Threat Management, your business gets full protection that includes intrusion detection and prevention (IPS), antivirus, antimalware, VPN for remote connections, URL filtering, application-based network access control and data leakage protection.

Yes, EXATEL has several data processing centres in Poland for its own needs and those of its customers. Our Data Center guarantees the highest standard – we are able to meet requirements of our customers from the banking sector and public administration.

Creating your own Data Center means incurring huge financial expenses. By using our services, you significantly reduce costs related to Data Center maintenance (paying experts, cost of electricity, air conditioning service, servers) and gain direct connections to over 450 operators, while taking advantage of the geographically dispersed structure of the Data Center.

This service is addressed to companies that have critical data and applications that require storage in a professional Data Center, companies that require a high level of data security and business continuity, and those that have multiple branches and need to share IT resources.

The Managed Firewall service means that EXATEL takes the responsibility for device configuration upon deployment and during the entire contract validity period, dealing with updates and adapting them to changing needs. If you are using an EXATEL line, you do not have to worry about a location for storing the device in your server room.

Yes, EXATEL has been fully state-owned since 2017, but it operates primarily in the business market and internationally.

Unfortunately not - our offer is dedicated solely to institutional clients.

We use various tools, depending on the needs of a given team. The software list includes, among others, ZOOM, Signal, Mumbler and Rocket chat. The latter two are the favourites used by teams working on our research and development projects.

The company was established as a result of a union between the power sector company ‘Tel-Energo’ and the telecommunications enterprise ‘Telbank’. Since the merger (October 2004), we have been using the name EXATEL.

Most certainly! We have prepared the Zoom EDUcation package for the educational sector. It covers, among others, 20 video-conference rooms, together with technical support for a period for 12 months. This is a perfect solution for schools and universities that are forced to conduct remote teaching under the current pandemic situation.

As a company controlled by the State Treasury, we are familiar with the specifics and needs of the public sector. This is why we know well that ensuring service quality and security is of utmost importance for public institutions. The good of the state is written in the DNA of our company.

It is an infrastructure used by the most important systems responsible for the safety of Polish residents, e.g., the 112 emergency number, System of State Registers (contains key data of Polish citizens) and Central Register of Vehicles and Drivers (CEPiK). Several thousand locations throughout Poland are coupled to this network. Our backbone network with a length of over 20 500 km is the core of OST.

We work in small teams and apply agile methodology. Each one of these teams is responsible for breaking down and evaluating the tasks conducted within each sprint. We have our own dev-style and a list of good programming principles. Each task is implemented in accordance with git-flow. Moreover, each new functionality is fully verified via unit tests. In accordance with our standards, a finished code must be subjected to code review by the team members. To optimize work, we use automation tools – CI with Jenkins, Ansible scripts for installing and configuring dependencies, linters for correct style, various checks, etc. Ultimately, the entire software undergoes integration tests within a test environment.

Of course not. We focus on what we do best – software development is one of such things. On the other hand, when, for example, building integrated or optical circuits, we search out Polish subcontractors who specialize in such work. It must be underlined that we are open to cooperation with the world of science. We are currently working with: Warsaw University of Technology, Silesian University of Technology, Cardinal Stefan Wyszyński University and the War Studies University – among others.

We work in two areas Java and C++: – Java 8/11 – Framework: OSGI + Apache Karaf – Unit tests: Spock + Groovy – Integration tests: Docker, Terraform, Vagrant – CI: Jenkins – Nexus 3, Git (BitBucket) repositories – IDE: IntelliJ IDEA Ultimate Edition and C/C++ (compiled with C++17), CMake, Java, Python, gTest/gMock for unit tests, Jenkins, git, Bitbucket, Sonar. IDE is arbitrary - with some people using VS Code, while others use JetBrains IDE. We primarily work on Linux.

No, we have been dealing with research and development projects for years. Initially, in 2014-2017, we were a member of the international RAPID5G consortium. As part of this project, in July 2017 in Warsaw, we conducted the first European tests of 5G technology in public space. We are also developing cybersecurity services. An example here is our proprietary anti-DDoS TAMA. And that's still not all.

Telecommunications is a business based on technology. The expenditure associated with expanding a network with technologies enabling the provision of highest-level services constitute a significant cost incurred by ISPs. Therefore, like any other commercial company - we calculate strategic outcomes. If we see that building something from scratch is profitable – we act. Fortunately, technological progress makes it easier for us. This is especially so now, when specialized hardware is losing in terms of importance to software that can be virtualized and run on COTS servers.

We control the version using Git with a BitBucket remote server. Tasks are organized in JIRA, and documentation developed in Confluence and directly in the code (sphinx). The app is tested on many levels, with each of the components subjected to unit and functional testing. CI is conducted using Jenkins and, depending on the platform, additional tools, among others:

• linting (pylint, tslint, pycodestyle)
• formatting (clang-format, cmake-format, prettier, robot-tidy)
• statistical analysis (SonarQube)
• unit tests (GTest, pytest, jasmine)
• integration tests (selenium, RobotFramework, scapy)
• fuzzing (LINK: article by Michał)
• performance tests (pktgen).

If a code does not pass the tests, it cannot be embedded in the master version – this means it is not implemented. We use so-called quality gates:

• More than 85% lines of code must be tested
• Linter error number cannot increase.

Correct test results enabled implementing a new version within a test environment. This process is triggered on-demand and is automatic, using a parametrized Jenkins project. Ultimately, our testers manually test the application. We develop test scenarios in JIRA, using the Zephyr plugin.

Our use of agile methodologies enables us to constantly develop our product, implement new functionalities, and collect comments and suggestions from product end-users. Owing to daily meetings, we can solve problems on an ongoing basis and every team member is able to keep track of work progress within the project. After each completed sprint, the project has new functionalities used by the operators or clients. In accordance with agile methods, every completed sprint is analysed by our team in terms of possible streamlining in the work process. Agile project management worked very well in the course of work on the TAMA project.

As part of the development work on the TAMA project, we also collect feedback from our clients and SOC operators. This greatly facilitates the assurance of high quality services. Moreover, we analyse the requirements and implementation feasibility of reported functionalities - which enables continuous product improvement.

We rely on the expert knowledge of people working in our cybersecurity department, as well as SOC operators directly handling the attacks and the network security of our clients. We follow the latest trends and technologies in the cybersecurity domain on an ongoing basis. Within the research activities, we also cooperate with consultants from technical universities and students.

We start our cooperation with the client by suggesting network security options, as well as conducting workshops presenting available TAMA functionalities. Based on our standards, we configure the network according to the client’s predefined parameters and product operation scenarios.

We use Jenkins to automate the tests. After it receives a notification from Bitbucket, it triggers a series of tests for each of the system components. The integration tests of the GlaDDoS filter mechanisms we undertake are one of the more complicated. They automatically trigger the filter on virtual local TAP interfaces, hook up to them through Python and use Scapy to generate packets and observe GlaDDoS response to transmitted traffic.

Slack cannot be installed on premises and is not end-to-end encrypted. This is why we use a variety of tools, as per need. For instance, we apply Signal - for fast ‘casual’ communication and notifications. This is a cloud-based solution open source product with end-to-end encryption. We also use Mumble - a form of virtual presence that resembles a radio. Usually, the entire team is available ‘on standby’ in rooms, so that it is possible to talk or ‘call’ a meeting without any trouble, much like in a real-life office. Regarding Rocket chat – covers all written ‘ongoing’ communication. Theme rooms and bots that notify us about important events, e.g., like a broken (or repaired) build or performance test results. All this is within our reach, which greatly facilitates work. As to Zoom - if we want to watch or a screen needs to be displayed – this is what we apply. We have our own on-premise server, which makes you feel slightly better.

1. Commented code (doxygen)

• Explaining the intent behind a method, class or code fragment, if necessary. This enables easier understanding of the author’s intentions and verifying whether it really works that way. In the case of modifications, it allows making sure that the intended behaviour is not deteriorating.

2. System documentation in a repo (sphinx)

• architecture
• operating concept
• division into components
• main interfaces
• technical documentation on filter operation (what kinds of attacks are detected and how)
• GlaDDoS network model - how does a network device behave
• administrator documentation
• documentation of system roles and privileges

3. Changelog - description of changes relative to the previous version:

• What is the business sense of changes?
• Release notes: what changes need to be done manually during deployment (e.g., associated with data model migration).
• What are the technical changes relevant from the team’s perspective?

4. Analytical, operational and system documents (confluence)

• What are the functional or visual changes experienced by the users?
• User documentation

5. Task board in JIRA.

Both the GlaDDoS filter and the Aperture probe require us to extract information like “what configuration applies to a given IP address?”. It is often additionally necessary to use the ‘Longest Prefix Match’, i.e., a configuration for 1.2.0.0/24 has a lower priority than for 1.2.3.0/28, if we enquire about 1.2.3.1, but the configuration actually applies to a 1.2.4.4 query. Sometimes, however, we want to know all applying configs (that is, for 1.2.3.1, both 1.2.3.0/28 and 1.2.0.0/24). Hardware solutions to this problem often include the quite expensive TCAM memory. However, we have developed a purely software-based solution. An algorithm frequently used to solve this issue is the LCTrie. We use a simple TriTrie algorithm, which, in practice, works faster with smaller data sets than the found reference LCTrie implementation. In addition, it is easily expandable, so it works with:

• IPv4 and IPv6,
• longest-prefix-match and ‘all match’,
• small configuration data (thousands of entries) and GeoIP (covering the entire IPv4 space).

TriTrie is generated statically, and then no longer modified. Where we need to maintain a dynamic address list, the code has to be efficient and locks cannot be used (i.e., no memory allocation), we use bloom filters, in the case of which adding an IP address comes down to setting certain bit values to 1. Bloom filters can cause false positive errors when reading, therefore, they cannot be applied in all cases. On the other hand, they do not enable removing added addresses, hence, they are changed and replaced with new, completely clean ones, every now and then.

The project is made up of several components:

• aperture - probe in C++17
• gladdos - scrubber in C++17 and dpdk
• chell - system configuration, operator and administrator interface; it consists of a backend developed in python/flask and a frontend developed in angular (we use current versions)
• controller - consisting of queue workers and detector, is responsible for collecting statistics.

We also use Debian Stable distribution and the packets that come with it. We work on NoSQL databases: redis and elasticsearch. All components are run in docker containers and managed by docker-compose - in pre-production environments and docker-swarm - during production.

This service includes secure and symmetric (with full bandwidth guarantee) access to the public Internet network. The access is based on our wide area IP MPLS network in the case of which the network traffic optimization is a priority.

The numerous benefits of this technology include the ability to build cost-effective infrastructure and own services, high service reliability, transmission security and the ability to manage the service independently or with the support of EXATEL experts.

The service consisting in the lease of telecommunication lines is a solution for anyone who needs infrastructure to transmit large volumes of data (up to 100 Gbps) or plans to develop their infrastructure in the future.

Voice as a Service is the next stage in the evolution of the traditional telephone exchange. The solution operates in the cloud and is accessible through an IP network. Compared to traditional systems, our VOIP solution requires little hardware.

We dedicate our service to companies and organizations that do not have their own telephone exchange or are rapidly expanding. The VaaS solution is scalable and can be easily customized.

The service is able to present a number or block it, has a wide selection of call forwarding and dialling facilitations. VaaS also allows for basic conference calls.

Our solution consists of a virtual call center and high-tech tools for communication monitoring, troubleshooting and knowledge gathering. Because it is a cloud-based solution, no additional hardware investment is required – only computer and headphones.

The service is addressed primarily to companies that already have their own internal CC workstations, sell or serve their customers by phone, e-mail or other electronic communication tools and want to distinguish themselves with modern forms of contact with the customer.

The Zoom service is offered in two models:

• Hybrid – meeting traffic is hosted locally – part of the infrastructure can be located in the customer's server room, and part on EXATEL servers.
• Cloud-based – all meeting traffic is hosted in the cloud.

Zoom is a very easy to manage and expand tool that has a wide range of functionalities. EXATEL also guarantees the security of the recordings which are stored on servers in Poland.

To order services provided by EXATEL, it is best to contact us via the contact form on the website, by email: bok@exatel.pl or by phone: 801 27 10 44.

The Ethernet standard is the basis for many technologically advanced services related to access to server resources or to the Internet.

The service enables leasing of the lines nationwide and globally, thanks to EXATEL's extensive cooperation with partners all around the world.

Providing a hotline facilitates contact between a potential customer and the company. The number can serve a typically informative function or can be an element of company marketing campaign. The hotline can also be used for internal needs of your company. Solutions such as One Number are commonly used by companies for which customer service and image is the priority.

No. If your business location changes, the hotline number will remain the same. This way you can easily maintain communication with your partners and customers.

This service provides a special hotline number available from landline and mobile networks, from which calls will be forwarded to a designated subscriber number. One Number allows calls from fixed or mobile networks to be forwarded from the 800 and 801 numbers to a designation number as specified in the National Numbering Plan (PNK). This number can be a number in the EXATEL network or in another domestic telecommunications operator. You can also transfer your number to EXATEL.

Yes, by establishing cooperation with us, the operator has the possibility of sending SMSes to all networks in Poland and most European Union networks. What is more, they also have the possibility to receive text messages to own MNO or MNVO networks – to the assigned or acquired mobile numbering ranges.

EXATEL is one of the few companies that offer Points of Interconnection between operators in the SMPP standard for SMS exchange.

The IP telephony service is designed primarily for companies that already have a VoIP exchange or are planning to purchase one.

The VOIP service offers companies several interesting solutions, including: the possibility of saving numbers used and transferring them quickly and easily, location-specific zoning numbering, detailed billing available on an ongoing basis, fax calls, CLIR and CLIP calls, and security.

Unlike analogue and mobile telephony, it allows you to make calls from anywhere in the world without any cabling. The only condition is Internet access.

We have been providing high-quality voice and transmission services for over 25 years. We provide our clients with, among others, the possibility of data transmission in Ethernet technology, leased lines (Wavelength), data transmission with the lowest latency, VaaS (Voice as a Service), IP telephony and Call/Contact Center, hotline and Zoom for companies.

EXATEL has its own, constantly extended transport network built in a ring structure using SDH/DWDM/OTN technologies. This solution allows us to support increasing capacities and improve the quality and range of our network (in Poland and abroad). The network is supervised by experienced NOC EXATEL engineers who monitor our services 24/7.

Wavelength ensures a connection between two locations via a high-bandwidth infrastructure based on a dedicated optical channel. This guarantees the client an entire exclusive band and the highest ‘transparency’ level for transmitted data.

It is a so-called ‘high bandwidth service’. It is based on Ethernet technology and is terminated with a Fast Ethernet or Gigabit Ethernet switch.

No - the service enables unlimited symmetrical Internet use (same uploading/downloading rate) within the purchased bandwidth.

EXATEL’s fibre-optic network is used to provide the services. It offers a high range of bandwidths - up to 100 Gb/s and good quality parameters.

The service enables connecting geographically dispersed client sites into a single WAN network via secure transmission with guaranteed data, voice or video quality parameters.

The MPLS IP VPN service allows, e.g., to prioritize transmitted traffic, which enables ensuring effective performance of all applications or services applied by the company.

A router at the client’s premises is an integral element of the network management system in MPLS technology. Its task is to ‘mark’ data packets in order to define the service classes, routes and priorities. The router is configured by EXATEL’s technical talent and is adapted to service parameters.

We use a dedicated high-performance network to provide Low Latency services. Owing to continuous expansion and constant monitoring, we minimize the impact of network devices on the lags and are able to meet the most stringent parameters.

IVR is a Call Centre functionality that involves automatic playback of voice announcements - it enables interactive caller handling.

EXATEL MWLAN is not only a managed wireless network, but also a professional and easy-to-use marketing tool that can be useful for customer profiling, targeting of promotions and services, and collection of user data. All of this provides valuable information to help your business grow.

Thanks to EXATEL's direct points of interconnection with mobile and landline networks in Poland and abroad, it is possible to make voice calls to any corner of the world. Termination may be performed in attractively priced Standard option (while maintaining good quality parameters of the service) or in the Premium option – for customers who seek the highest quality.

EXATEL is one of the largest voice transit operators in Poland. We cooperate with over 450 operators in the country and worldwide. What distinguishes us from our competition is the fact that we have an extensive network of points of interconnection implemented across the country, for example in Frankfurt and London, and we have large IP interconnection with Tier 1 operators.

The offer is addressed to domestic and international wholesale operators who are interested in the exchange of telecommunications traffic.

The BGP enables dynamic routing, which gives users the ability to choose the optimal route for forwarding packets.

It is a service of fast and symmetric Internet connection with guaranteed availability (with BGP).

The service uses BGP. It requires its own AS number and IP addresses (the customer's own PI or PA addresses or the EXATEL PA address).

Ethernet is a well-known technology used to build your own network infrastructure. It gives the opportunity to use it extensively in creating your own services and is cost effective at the same time.

It is known as high capacity service. It is based on Ethernet technology terminated with Fast Ethernet or Gigabit Ethernet Points of Interconnection.

Low Latency is a data service that guarantees the lowest possible data transmission latency. The RTD (delay) parameter is guaranteed in the agreement.

We use a dedicated high performance network to provide Low Latency services. Thanks to constant expansion and monitoring we minimise the impact of network devices on latency and we are able to meet restrictive parameters.

Yes, the SLA for the Low Latency service guarantees the lowest possible data transfer latency.

It is a symmetric Internet access service; it covers the resources of participants at Internet Exchange Points with which EXATEL is connected.

This is an attractively priced addition to the Internet access already in use. as a part of a service, you will also have a direct access to EXATEL's network of peering partners.

Yes, it is possible by using symmetrical link technology that gives full bandwidth guarantee.

The SLA is a part of the service and under it we provide a guarantee for parameters related to the availability of the service. At the same time, we are constantly optimising IP traffic which allows us to verify whether the current traffic distribution is effective in terms of costs and call quality.

Alien Lambda is an alternative to traditional leased line service. This solution makes it possible to share a specific wavelength in the EXATEL DWDM/CWDM systems. What distinguishes this service from a regular lambda (wavelength) is that the optical signal supplied to the EXATEL system is generated directly from transponders owned by the customer.

An SLA agreement is an element of this service offer. Under the agreement, we will guarantee the parameters associated with service availability. At the same time, we will continuously optimize IP traffic. This allows verification of whether the current traffic distribution is effective both in terms of costs and connection quality.

This service utilizes the BGP protocol. In order to run it, you require your personal AS number and IP addresses (personal client’s PI or PA addresses or EXATEL’S PA addressing).

Yes, we own a large number of IP exchange points with Tier 1 network operators.

In the case of the Premium service, traffic is transited by selected partners and exchange points. For you, this means guaranteed service quality, ensured CLI, roaming, fax sending and eliminated FAS presence.
