Data network

Whether it's about data networks, landlines, ISDN or All-IP - we can take a close look at your contracts and agreements

Planning, designing and reducing the cost of a functioning network requires expertise ranging from LAN, WAN and WI-FI to new, challenging technologies such as cloud applications, software-defined WANs or the conversion of ISDN on All-IP.

Improving prices and services

Deep technology is one thing but just as important is sufficient knowledge of the provider market and the terms currently on offer. Conducting a professional bidder survey, for example by means of a tender, is the option of choice when facing the complex requirements of companies of a certain size. This approach never fails to pay off for the tendering party since it allows a transparent comparison of engineering requirement criteria and commercial parameters. Furthermore, such a tendering process will ensure the essential element of competition that will ultimately produce an optimum final outcome.

heitzig makes the opportunities and risks associated with various suitable solution approaches transparent. Together with your project team, we develop a tailor-made solution and put it out to tender.

However, it's not always necessary to implement comprehensive calls for tenders in order to ultimately reach a specific goal. There is also the lean option of achieving the desired benefit without going through an elaborate tendering process! This approach is recommended when certain other factors come into play which should be agreed on between heitzig and its client in advance.

During its long years of project experience, heitzig has developed a highly successful survey model combined with a strategic approach we use to complete optimization projects through know-how and outstanding market expertise.

Benefits of Software-Defined WAN

Although each SD-WAN project basically involves similar structures and processes, company-specific details and requirements are completely unique and new challenges with each roll out.

In the age of cloudification, SD-WANs promise to combine the cost benefits of an Internet connection with the service levels of an MPLS network. An SD-WAN not only simplifies the configuration and management of the WAN, but can also reduce costs by outsourcing bandwidth-intensive and less critical applications and data to the cheaper public Internet (Traffic Offloading).

If necessary, bandwidth requirements can be increased at short notice and then reduced again. This means that the higher costs for more bandwidth are only incurred in the actual time period.

SD-WAN may be of interest to the following target groups:

  • Companies with larger international networks
  • Companies that already use VPN alongside MPLS
  • Customers who want to move applications to the cloud or get more and more applications from the cloud

From ISDN to All-IP

Across Europe, you're in the middle of the all-IP transition – ISDN is being shut down. Those who have not yet dealt with the changeover are in a situation where they need to find out about it in a timely manner.

By the way, a conversion from ISDN to IP of your ISDN sub-site systems takes place in three steps.

The network that can serve all of these services is called the Next Generation Network (NGN). In the future, customers will only have a single all-IP connection over which voice, data and videos will run. A separate ISDN port next to the Internet port is no longer required.

There are also a few points to consider when switching, e.B. there are some ISDN-based add-on devices that might not work under All-IP.

Migrations often fail due to internal resource shortages. Simply transfer the entire conversion process with your provider to an external project manager. In addition, the optimization approach of your fixed-line contracts is always included in our performance.

We would be happy to help you explore your own specific requirements!
