(picture: 5G Radio Unit, 5G-Lab Weiterstadt) Together with our parent company Logicalis GmbH, we are building a new private 5G campus network in the Technologiepark Adlershof which will be up and running by Christmas this year. The advantage compared to a public network: fewer users share the available bandwidth, making it more secure and stable and new innovative ideas and business models can be tested under clear conditions. In addition, a "5G showroom" will be created in 2022 as an innovation center. Interested parties can experience the new 5G technology live on site and develop and test their own use cases. WISTA Management GmbH will provide a basic version of the network free of charge, while Logicalis GmbH and our specialists at siticom will be responsible for customer-specific adaptations, integration and operation. Roland Sillmann, Managing Director of WISTA Management GmbH: "Our task is to provide the companies in the Adlershof Science and Technology Park with the framework conditions for their economic growth. This also includes looking at: What will the companies need in a few years? 5G will bring a boost, and that's why it's so important that we offer an environment to test and develop them further to companies already working on their 5G applications." But WISTA also wants to show ideas for companies that have not had a role in 5G yet, so they have the opportunity to learn more and try it out. "5G technology will enable applications that we don't even know about today," Sillmann said. "But most importantly, 5G will rapidly advance the Internet of Things, driving Industry 4.0." In our Insight "Innovation platform 5G" you will find our use cases and solutions around private 5G. You can get a quick overview of our services in the Campus Networks section. Thanks to Technologiepark Adlershof for their story "schnell, schneller, Adlershof" about our exclusive 5G Campus Network!

On November 18, 2021, Europe's leading telecom providers, such as Deutsche Telekom, Vodafone, Telefónica and others, published a joint paper on the topic: 5G / OpenRAN for Europe. The remarkable thing here is that siticom has managed to emerge here as THE integrator for Europe! (Source: BUILDING AN OPEN RAN ECOSYSTEM FOR EUROPE, page 16) This report is based on the findings of independent TMT management consultancy Analysys Mason and calls on policy makers, EU Member States and industry stakeholders to work together and urgently prioritize the Open Radio Access Network (OpenRAN). This will ensure that Europe continues to play a leading role in 5G and, in the future, 6G. An open, intelligent, virtualized and fully interoperable radio access network is a necessary condition for Europe to achieve the goal of 5G for all in 2030. This will help create stronger and more resilient supply chains and platforms, and promote digital autonomy and continued technology leadership. New open and decomposed architecture, software and hardware (such as OpenRAN) will enable operators to flexibly extend 5G to more users in a cost-effective, secure and energy-efficient manner. This flexibility will stimulate more innovation across industries in areas such as telemedicine and smart factory. It is important that the EU works together here to maintain its competitiveness, technological leadership and resilience, otherwise Europe risks falling behind North America and Asia in the development and deployment of next-generation networks. It also lists five policy recommendations that can narrow the gap with other international regions to create a vibrant ecosystem of European participants and provide the foundation for future mobile communications: Ensure high-level political support for OpenRAN European Alliance for Next Generation Communications Infrastructures and a roadmap for innovation Policy makers should offer and support financial and fiscal incentives to operators, vendors and start-ups Promote European leadership in standardization Collaborate with international partners Currently, European vendors are not represented in all six major technology and service categories that make up the OpenRAN value chain, such as cloud hardware. They also outnumber non-European vendors in semiconductors. Implementing the report's recommendations would give a boost to domestic, smaller suppliers and strengthen European leadership in this important technology, which would also have a positive impact on adjacent industries such as cloud and microelectronics. The report concludes that Europe needs to include OpenRAN as a pillar in its industrial policy and Digital Compass strategy and underpin it with the right policy framework. This will have a positive impact on other key technology areas such as cloud, software and chipsets, and contribute significantly to the broader technological ambitions of a digital Europe.

What’s on the menu? Nothing less than 5G. Imagine siticom as a chef, cooking and composing the different courses of a 5G Menu. Through our easily digestible cookbook for 5G OpenRAN you will understand the difference between this menu and a ready meal (a vendor locked legacy solution). But why different courses and flavours? Is 5G not like any other WiFi? It might not and it should not. As an integrator, we understand the numerous use cases for 5G and we aim to understand all of them. Thus we have an intricate understanding of the 5G service layer, the necessary virtualization stack and the underlying synchronized network. This cookbook explains all of it. All in a quick, simple and metaphorical view. It’s more than just a “OpenRAN for dummies” – you will see that open approaches like OpenRAN are part of our DNA and our perspective on business solutions. PDF download here: reading time 8 minutes.

(Source: bahnbauprojekt-stuttgart-ulm.de) The Stuttgart 21 project is a complete reorganization of the Stuttgart rail hub, which was concluded in 2009 as part of a financing agreement between the federal government, the state of Baden-Wuerttemberg, the state capital Stuttgart, the Stuttgart Regional Association, Flughafen Stuttgart GmbH and Deutsche Bahn. The central structure of this project is the future main station. In addition, the Stuttgart rail hub will be fully equipped with digital control and safety technology in a Germany-wide pilot project. More than ten million passengers are expected to benefit from the expansion of the Stuttgart rail hub in conjunction with the new line to Ulm. What is siticom doing in this project? siticom is responsible for planning and interface coordination for rail technology (construction measures for equipping telecommunications systems) in eight planning approval sections in the subproject of the major Stuttgart 21 project. The total volume of the project includes the control and safety technology, 50 Hz systems, as well as the cable planning for the track cables and the laying of fiber optics in empty conduits and cable troughs. Furthermore, it also includes all emergency call pillars and the BOS' slot cable, the transmission technology of the IP access network and the SDH network. In addition, it also includes the fire and hazard systems, the reporting system (DBMAS) and the BOS radio systems (digital, TETRA). The eight planning approval sections of Stuttgart 21 are: Valley crossing with main station (PFA 1.1) Future through station between Kriegsberg in the north and Kernerviertel in the south. Consisting of a new platform hall, with a concrete shell roof, and the Nordkopf and Südkopf tunnels. Filder Tunnel (PFA1.2) A 9.5-kilometer tunnel connecting Stuttgart's main station and the Filder plain. Airport link - new line with NBS station (PFA 1.3a) and Gaeubahn line (PFA 1.3b) Realization of the connection of Stuttgart Airport and the trade fair center, to the long-distance and regional rail network and two planning approval sections. New line with NBS station: Comprises the 5-kilometer section of the new Stuttgart-Wendlingen-Ulm line along the A8 to the Wendlingen Filder area. Gaeubahn routing: Includes the connection to the airport from and in the direction of the Gaeubahn with the Rohrer curve, the station 3rd track parallel to the Stuttgart Airport/Traide Fair Suburban train station, the tunnel Airport curve, and adaptation measures on the line between Stuttgart-Rohr and the airport. (The planning approval procedure for PFA 1.3b is currently underway). Filder area to Wendlingen (PFA 1.4) A 10-kilometer section comprising the high-speed line on the Filder from the eastern edge of the airport taxiway to the crossing of the Neckar at Wendlingen. Feuerbach and Bad Cannstatt access (PFA 1.5) The two tunnels at Feuerbach and Bad Cannstatt provide access to the new main station from the north. In addition, the Suburban train will have a new underground line there, shifted to the west, with the Mitternachtsstraße Suburban train station. Ober- / Untertürkheim feeder line (PFA 1.6a) Connection of Stuttgart main station with the Neckar valley, using the new Obertürkheim tunnel with the branch to Untertürkheim. Untertürkheim stabling yard (PFA 1.6b) The new Untertürkheim stabling yard is being built on the site of the former marshalling yard between Stuttgart-Bad Cannstatt and Stuttgart-Untertürkheim.

Our Currenta project is a brilliant example of responsibility that feels fulfilling and rewarding. Every single component in a complex environment was delivered successfully according to a sophisticated planning. What does siticom do in this project? Part 1: Implementation - Currenta Backbone Project As part of the Currenta Backbone project, an IP data network was set up for the CHEMPARK operator at all three sites, connected via a double fiber optic ring. The aim here is to offer the companies at the chemical park a high-performance and future-proof ICT infrastructure for their production facilities, logistics processes and offices. Within the scope of this project, all technical components for the operation and control of the data network were supplied, commissioned and integrated. Here, siticom took on the role of system integrator and handed over a "turnkey" and immediately operational solution to Currenta. This enables Currenta to offer and operate modern, high-performance ICT services for its CHEMPARK partners. The operation and monitoring of this data network is also carried out here by siticom. Part 2: Commissioning In October 2018, the network was put into operation and additional services for 24/7 monitoring and fault clearance of the Currenta backbone network were implemented. To meet the steadily increasing demand of CHEMPARK partners for site connections and data bandwidths, additional ports have been continuously connected and put into operation: Tripling of the number of customer ports that can be connected since the start of the project in 2018. Expansion of transmission capacity between the CHEMPARKS based on the installed fiber-optic double ring. Connection of approx. 560 customer services in just 2 years. In addition, siticom also solved challenges such as addressing operational issues such as access, contact partners, responsibilities, cable management, documentation errors. Adaptations to very different procedures for final acceptance of Currenta services were also required. The advantage: The network runs smoothly without disruptions or capacity bottlenecks, with high customer satisfaction, continuously monitored by the siticom Network Operation Center NOC. On this basis, Currenta can concentrate on expanding its ICT service portfolio, on the one hand to develop additional, individualized services for existing customers and on the other to provide standardized services for new customers at the CHEMPARK. As a long-standing and trusted partner, we will continue to be available to Currenta for the operation and further development of the project. Learn more about siticom's Campus Networks activities at: https://www.siticom.online/network-transformation As well as in our Insight Innovation Platform 5G. About Currenta: In addition to on-site substance and energy supply, a wide range of analytical services and modern environmental management, Currenta's range of services primarily includes extensive infrastructure services and reliable safety concepts. For example, it operates an IP/MPLS network for companies in the chemical and pharmaceutical industries. Currenta manages and operates CHEMPARK, one of the largest chemical sites in Europe, at its sites in Leverkusen, Dormagen and Krefeld-Uerdingen. As a modern service company, they aim to create optimum research and production conditions for their resident customers. Source: https://www.currenta.de/chempark.html

#1 The moment you realize it's suddenly about something completely different *translated from german Welcome to "My typical Working Day @ siticom", a blog series by and with me, Amelie Weber, in which I interview a colleague from different areas of siticom about their typical working day. It's about professional background, responsibilities, opinions about home office. But sometimes, like today, there comes this moment when you realize that it's suddenly about something completely different than originally planned - women in IT. For my very first contribution to this series, I have my colleague Tanja Lintner, QGIS Developer at siticom, as my guest today. A: Hello Tanja, so tell me, I really can't imagine what you actually do at our company. I only know that you have been with us since the beginning of the year. T: Yes, I still don't really know what I do. [laughs] I'm Tanja Lintner, I studied geography, then I did an apprenticeship as a tourism clerk. Then, in a roundabout way, I found the job at the competitor and there I was basically the "girl for everything". I was a back-office employee for construction and supported my site manager, worked as a planner, and then trained as a project manager. I also did a bit of bookkeeping on the side. A: Oh, that sounds exciting. T: I've been at siticom since the beginning of the year, initially supporting the accounting Telekom tasks of a colleague who is now doing a semester abroad. At the same time, I am also involved with other clients, both in planning and structuring. We are currently in the process of switching from AutoCAD to QGIS*, which is both challenging and exciting. A: That's actually quite a lot that you do. What does your typical workday look like? T: My typical workday always starts at around 6:00 a.m. A: Oh wow, that early? T: Yes, so I can finish work earlier. [laughs] The first thing I do is look at all the new Telekom orders that have come in and then feed them into our system. Apart from the usual mails and small things, I mainly work on our Telekom project, e.g. entering measurements in our system, etc. Once I've done that, I can also prepare the invoices for the accounting department and coordinate the planning activities for other customers, obtain line information, in other words, the normal planning activities. And I'm actually also in the home office 100% of the time. I live in Würzburg and the closest geographical location is Weiterstadt. When things are going well, I'm on the road for 2 ½ hours by bus and train. A: Okay, that's a really long way. What are the advantages of working from home? Other than the long commute you would have? T: There are so many of them. For one thing, working undisturbed. I can just put my phone on silent for half an hour and get my work done without being disturbed. Then personally: I have two cats and that is just insanely life-enriching for me when someone suddenly comes and briefly wants your attention and to be stroked. That also lets me switch off for a moment and think about something else. And then also in terms of perspective: I'm getting married in two weeks and in the next 2 to 3 years I'll be planning a family with children. Home office and flexible working hours were a reason for me to switch to siticom. I now have my work-life balance even more under control and have the opportunity to better organize family life, which is coming up at some point. Especially when you're a woman in the IT industry [laughs]. A: I think especially the point about children or family in general is well covered with the work-life balance. Do you also see any disadvantages of home office? T: I think that not every person is suitable for the home office, because social contact with colleagues then takes place at most, as with both of us, over the phone or via webcam. For many people, this interpersonal contact is missing. You meet briefly in the coffee kitchen and talk about more personal topics. A: You just briefly mentioned working as a woman in the IT industry. It's a well-known fact that the proportion of men in the IT industry is higher. What do you think is the reason for that? T: The traditional view is that the woman goes in the social or interactive direction, while the man sits in front of the laptop and programs. The main problem that most women may see is, "You have to stay on it." I realize that now with QGIS, too, once you're really out, you're out. You always have to stay up-to-date and see what's coming up, for example, with SQL (Structured Query Language). SQL is a language like English, if you don't speak it for a few years, it's very difficult to get back into it. However, I believe that this is now changing quite a lot, more and more women are entering the IT sector. Simply because society is rethinking the idea that men can also take parental leave and there is also the option of home office. As a result, many women can imagine pursuing such a profession without having to fear that they will be out after 2 years of parental leave. A: Could you give some advice to the women out there who are a little bit afraid to start in the IT industry? For example, they might be afraid of getting nasty comments or maybe being treated unfairly. T: I don't think I can formulate in a positive way what's on my mind right now. Unfortunately, previous experiences were not the best for me, once bitten, twice shy. The only thing I could say would be "Don't take it to heart, because you know how good you are!" A: On the one hand, a really nice quote... T: ...but it sounds so unsatisfying! [laughs] A: I know that too, I have also received some unpleasant comments myself in the past. That wasn't easy, especially at the beginning. You're young, you get insecure and don't dare say anything against it. But you learn to deal with it over time and maybe even speak up. T: Yes, exactly. I don't think you should be afraid of it. I don't think there is THE perfect job, whether for a woman or a man. If I'm a kindergarten teacher, people say, "Yeah, sure, she plays with kids all day long, that's zero responsibility.“ If I'm a teacher, "Ah well, she's only on vacation. She just does her lessons and that's it." As a woman in IT, I once heard the following during my apprenticeship: "I would have preferred to speak to Mr. XY. I generally only do that with gentlemen." A: How did you deal with that? T: Put it through and thought a**hole. [laughs] A: That's the right attitude. [laughs] T: I just can't grow a penis in a hurry right now. I have to show that I am worth it. So what I can do, that I can do it, and that I don't have to prove it to everyone. Sometimes I have the feeling that men do this because they feel threatened, in the sense of additional competition on the job market. But I also think that only those who are insecure about themselves do that. A: I agree with you 100%! T: But in the meantime I am above that. I know what I can do, I know who I am. At work, it's important that I make connections and I don't want to upset any customers, but at the end of the day, it's just a job A: It's also said, "You work to live, not live to work." T: Exactly. And that's why, as long as I'm happy in my private life, I can stand that there are people like that. [laughs] A: But fortunately that's not the case with us. Or at least not known. At any rate, I haven't noticed anything yet. [laughs] T: Nevertheless, I still have a bad gut feeling. For example, I had a small discussion with a colleague in which I was wondering (like I was wondering in many situations before) whether he would really take me seriously because I'm younger, a woman and have less professional experience. We clarified this afterwards and it turned out that it was simply a misunderstanding. I think most women feel that way, though. It's similar to the situation when a man walks past you and just says a polite "Hey, you look nice today" to you. Without ulterior motives. Most of the time you have these exclamation marks in your head "Ahh help, leave me alone!". A: Yes, I know that too. Sometimes I also have the feeling that colleagues think to themselves "Well, let's let her talk" and don't take me seriously, even though it's not really like that. [laughs] T: Yes, exactly. [laughs] I know that. And that's exactly why I think the best advice to women is simply to persevere. And think a**hole. For me personally, this saying is important: "Change it, love it, leave it" - If you can't change it and you don't love it then leave. Just because I have this job doesn't mean I have to be there forever. A: Yeah, that's the right thing too! Like you said, it's ONLY A JOB. Thank you Tanja for your time and this conversation. It was a great pleasure for me. *QGIS is a free geographic information system software for viewing, editing, capturing and analyzing spatial data.

#2 DDI, DHCP, IPAM,.. Wait! What!? *translated from german Welcome to "My typical Working Day @ siticom", a blog series by and with me, Amelie Weber, in which I interview a colleague from various areas of siticom in each episode about their typical working day. For example, I talk about professional background, responsibilities, opinions on home office or I learn a new foreign language here. For my second contribution to this series, I have my colleague Lars Bruné, Tech Lead Network Transformation at siticom, as my guest today. A: Hi Lars, glad it worked out! Please introduce yourself briefly: Who are you? Where are you from? How long have you been with siticom and what are your responsibilities? L: Hi, I'm Lars and I'm also here. Since the middle of 2018 to be exact 😊. I studied informatics in Bonn, specializing in bioinformatics, and started as a working student at a partner company of siticom, in consulting engineering for voice networks, and then switched to siticom. Now I am mainly working in the area of Network Automation & Cloud. At the moment, my tasks can probably best be described as "Lead Architect & SRE DDI". DDI stands for DNS, DHCP & IPAM. Acronyms in acronyms... We develop and operate a platform for our customers, which on the one hand allows the automated operation and rollout of the DDI infrastructure and on the other hand gives the users the possibility to set the DNS records for their apps via self-service API. The "intent" concept plays a major role here. We try to abstract the "expert knowledge" as far as possible. To stay with the DNS example, a user should not have to explicitly make a request to have www.example.com (example domain) point to IP 1, but should instead be able to say www.example.com should point to all servers/load balancers that have the tag "app-example". We are not quite there yet but on a good way to get there. Besides that I'm a home at siticom since a few days/weeks now and as such contact person for my "homies" in the everyday topics that arise besides the projects. A: DDI, DHCP, IPAM,... Wait! What!? And now again for the people who don't know this "foreign language". [laughs] Could you briefly explain to me what exactly DDI, DHCP and IPAM mean? L: DDI stands for DNS, DHCP & IPAM. DNS is the Domain Named System, so resolving a name into an IP address, for example facebook.com into just the IP address. DHCP is the Dynamic Host Configuration Protocol, which is also a network protocol that can be used to initially configure network devices. We use this a lot in a large project environment for these zero-touch provisioning things, so that someone screws a router into a rack, it is turned on, and it then configures itself without anyone having to log in manually for the configuration from the network. IPAM is simply IP address management, because IP addresses are a finite resource, you have to take care that they are assigned sensibly and that there is a bit of order in it. It's simply an address allocation tool. A: Ah okay! Now I, who is not so much in the game, have understood what it's all about. [laughs] You always learn something new. And by "home" are you referring to our buddy program* for new employees, or are you the general contact person for any topic for all colleagues? L: At siticom we have this "home concept", because we have this flat hierarchy and not these typical organization chart style things, and in the middle of a circle of employees there is the function as "home". The function of the home is, in addition to the usual project manager topics, to be available for the usual concerns and questions, for example, to release all the hours in the BCS and to see that the people also book sensibly or also release vacations and also to see to it that the people also do regular training. In classic corporate language, you could also call it department head, I guess. [laughs] A: That's a lot of work for you. What does your typical workday look like? L: I usually start my working day around 9 o'clock. Since I mainly work with a client in the UK, I usually use the first hour to coordinate with my siticom colleagues and prepare for the rest of the day. Then I spend most of the day in various meetings with clients and the project team. I think this is both a curse and a blessing. On the one hand, it leaves little time for longer focused work on specific topics, but collaboration is one of the big drivers in the "agile" world and many issues can be resolved quickly and well if the right people get together for a few minutes. Besides the meetings, I spend the day recording the results in architecture diagrams, maintaining the backlog in JIRA, doing code reviews and every now and then I even get to type a few lines of code myself. A: I can hear that your day is really well organized! L: Well, at the moment I think I have half an hour between calls, sometimes less, but yes, I spend a lot of time in meetings and calls. A: Do you prefer to work in your home office to have some peace and quiet or do you also go to the office? L: At the moment I'm back in the office a lot (long live the air conditioning!). We have a few new colleagues, so it's a good idea to be in the office to be able to clarify questions quickly and easily, to sit down together to go through a few technical things and to get to know each other better over a coffee. Of course, this is also possible via teams, but the "information bandwidth" is simply much higher face-to-face. I think on average I work 50% from home and 50% in the office. A: Air conditioning is of course a must-have now with the hot temperatures! [laughs] So what are the pros and cons of home office for you personally? L: The home office, or rather "mobile working", of course offers a lot of flexibility. I can work from wherever I want and even spend Friday or Monday working from a friend's or parents' place. I can set up my home office entirely according to my wishes and needs and have the opportunity to work without a lot of distractions from colleagues. In our open offices, it's easy for there to be a lot of hustle and bustle, which can be distracting when you're trying to concentrate on your work. On the other hand, in the office I naturally have a direct line to my colleagues, there's a lot more exchange, even apart from the projects, and it's easier to create a "we" feeling. And the air conditioning. Definitely the air conditioning! [laughs] A: I'm right there with you! Both in terms of the peace/flexibility in the home office, the "we" feeling in the office, and the air conditioning. [laughs] Do you have any other topics or challenges in your work that you would like to talk about that might interest readers? L: I think all of the technical challenges that we have are water under the bridge as soon as I write them down, but for us as siticom I see a few challenges: Knowledge management and transfer for example. We have a very "wide" project environment with some customers and are involved in many topics. How do we manage to share knowledge efficiently as siticom without all of us being stuck in "catchup" or "sync" meetings all the time? The challenge around personal development goes in the same direction. As a company, we are committed to making our people better, and I think we are very successful at that! But how do we create opportunities - and above all the time to take advantage of them - for employees while we are on the road in projects and with customers? I personally think that the freedom to try new things, be it a new programming language, a new tool, AWS service XYZ, or whatever the cool kids are using at the moment is the basis for further development and innovation. In the end, we as siticom are also so successful because we manage to bridge the gap between the "old boring" (docker-compose on EC2 instances? So 2015!) world and the latest craze fresh out of the CNCF incubator. A: I'm glad to hear that we share an impression: we at siticom are very much ahead of the game, both technically and with our culture! Thanks Lars for your time and this conversation. It was a pleasure to meet you. *At siticom, all new employees have a buddy, who supports them during the onboarding process with technical questions and networking. The interview was conducted by: Amelie Weber Marketing Manager, siticom GmbH

Since 2022, siticom is now also certified for systematic energy management and thus trendsetting with five ISO certificates in the integrated management system Weiterstadt, 26 October 2022 The Integrated Management System (IMS) of siticom is constantly kept up to date and forms the basis for our certifications according to ISO standards. As part of an audit for the four certifications, quality (QMS), information security (ISMS), environmental protection (EMS) and occupational health and safety (SGAMS), siticom also faced the requirements for systematic energy management for the first time - and is now also ISO 50001 certified. The standard, which was first published in 2011, includes guidelines for recording energy flows in companies and for evaluating energy consumption and energy efficiency. The goal is to make a contribution to reducing primary energy consumption in Germany and thus to environmental and climate protection through certified energy management systems. "I claim we are one of the few IT companies with an IMS consisting of five 5 ISO certificates - and a sixth pillar, data protection, according to DSGVO (European Data Protection Laws). We started early on to intensively track and constantly develop our quality and security standards - this is not only our own claim, but also increasingly a critical quality feature for our customers". explains Dietmar Kauer, Security & Compliance Manager at siticom.
