The customer is undergoing a comprehensive transformation. All SAP ECC landscapes worldwide are being migrated to SAP S/4HANA, with the goal of introducing a standard template worldwide.
The program also includes the “RISE with SAP” migration and modernization program, which may involve migrating the landscapes of selected country installations to the SAP Private Cloud.
On the stakeholder side, the program reporting line extends to the company’s executive board and that of the implementation partner.
Fiserv Germany’s ERP landscape currently includes several non-standard SAP tools and applications that extend the functionality of the ECC environment and can often be integrated into downstream systems. As part of the transition to SAP S/4HANA, it is essential to assess the core functionality, integration points and future viability of these applications in order to determine their alignment with the target architecture.
The focus of the work is on providing expert advice and assessment to define the scope, strategy and roadmap for transitioning Fiserv Germany’s SAP ECC system to SAP S/4HANA.
The recommended best practices from SAP are followed and a structured approach is used to ensure a smooth transition with minimal disruption while maximizing business value.
This assessment forms the basis for a successful SAP S/4HANA transformation and ensures alignment with industry best practices, regulatory compliance and future scalability.
Migration Strategy Definition – assessment of available transition approaches based on business objectives, technical feasibility and SAP Best Practices.
Technical Readiness Assessment – conducting a system analysis to assess compatibility, custom code impact, data volume management, integration points and infrastructure readiness for SAP S/4HANA.

About the technology
What ISDN provides
ISDN, short for Integrated Services Digital Network, is a digital telecommunications standard for carrying voice, fax and data over telephone infrastructure. It replaced many analogue connections with clearer transmission, separate channels and signaling that supported business telephony. Euro-ISDN is the common European implementation found in many legacy installations.
Where it is used
Companies still encounter ISDN in established telephony, alarm, elevator, branch-office and industrial communication systems. Specialists support:
- PBX and call-routing connections
- PRI and BRI access design
- Fax, modem and alarm integrations
- Migration to SIP or hosted telephony
- Troubleshooting of legacy voice services
Ecosystem and skills
ISDN work involves telephone exchanges, network termination equipment, PBX systems, gateways and structured cabling. Useful adjacent knowledge includes SIP, VoIP, numbering plans, QoS, Ethernet, analogue telephone adapters and vendor-specific call-control interfaces. Professionals must understand both signaling and the physical handoff between carrier and customer equipment.
When companies need support
Freelance expertise is valuable when a business must keep an existing ISDN service stable while planning a replacement. It also helps during office moves, PBX changes, carrier faults, audits or the integration of older alarms and fax systems. In Germany, projects may combine established Euro-ISDN installations with newer SIP infrastructure, making careful documentation and transition planning essential.
What strong professionals deliver
A capable specialist begins with a clear inventory of lines, channels, numbers, devices and dependencies. They can read PBX configuration, trace signaling, isolate faults and coordinate with carriers without disrupting critical communication. Good deliverables include a migration plan, tested gateway configuration, updated diagrams, rollback steps and practical handover notes.
Remote and on-site work
ISDN analysis can often start remotely through configuration reviews, call traces, service records and guided tests. On-site work may still be needed to inspect termination units, cabling, PBX ports or equipment in a secured facility. Strong professionals define access requirements early, document every change and communicate clearly with internal teams, carriers and hardware vendors.
Frequently asked questions
Curious about ISDN? Here are the answers that come up again and again.
ISDN is mainly found in legacy business telephony, PBX connections, fax services, alarms and industrial communication systems. Companies often engage a specialist to maintain these services, resolve faults or plan a controlled move to SIP or another modern voice technology.
ISDN provides circuit-based digital voice and signaling through dedicated telecommunications access, while SIP and VoIP use packet-based networks. SIP usually offers more flexibility for distributed and software-based telephony, but migration requires attention to numbering, emergency calling, fax, alarms and existing PBX equipment.
ISDN work benefits from knowledge of PBX configuration, Euro-ISDN, PRI, BRI, SIP, VoIP gateways and carrier troubleshooting. Familiarity with cabling, network basics, call traces and analogue devices is also important when older systems depend on several connected technologies.
ISDN projects vary from a focused configuration change to a complex migration involving many devices and services. Choose a professional who has handled the relevant PBX, access type and connected systems, and ask for examples of similar troubleshooting or transition work rather than relying on general telecommunications knowledge.
ISDN support can often be performed remotely when the professional has secure access to the PBX, gateway and service documentation. An on-site visit in Germany may be necessary for cabling, network termination equipment, physical port checks or systems that cannot be accessed from outside the facility.
ISDN may be maintained when it supports critical legacy equipment that cannot yet be changed safely. Replacement is worth assessing when the carrier service is being retired, hardware is difficult to support, the business needs flexible remote telephony or SIP integration can reduce operational complexity.
ISDN quality is shown through precise diagnostics, clear documentation and safe change control. Ask how the professional identifies signaling faults, protects active calls, tests fallback procedures and records the relationship between carrier access, PBX settings, gateways and connected equipment.
ISDN assignments in Germany often involve Euro-ISDN, established PBX installations and coordination with carriers or on-site facility teams. Professionals should be comfortable working remotely where possible, visiting sites when physical checks are required and communicating clearly in the language expected by the client.
The average hourly rate of freelancers in Germany who have used ISDN in their recent projects is 98 €, which corresponds to a daily rate of about 783 € based on an 8-hour working day.
