The first objective was to incorporate all German Army telephone lines connected to the public Deutsche Telekom network into a voice VPNVPN

Virtual Private Networks are made-to-measure, network-based voice solutions that enable companies to integrate multiple locations into a single network – without the cost of setting up their own corporate infrastructure. A VPN supports applications such as central dial-in, central switchboard, teleworking, customer telephone services and contact management.

(Virtual Private Network), thereby creating a single "virtual" telephone system. A key priority was to reduce the administrative load on the Army by building centralized management of orders, complaints, and faults into the solution. A further wish was for itemized billing in digital form, allowing invoice data to be processed using the Army’s proprietary software.

All telephone lines linked to the Deutsche Telekom network at Army locations across Germany now form part of a single voice network solution, with T-Systems delivering end-to-end support. Billing is digital and comprises 37 detailed invoices - one for each of the German Army’s 36 administrative units, plus one master invoice. As an added bonus, the central order management facility offers a single point of contact at T-Systems for all administrative aspects of the solution.

The new solution has significantly reduced the Army’s admin workload. T-Systems now takes care of all orders, complaints, and fault management, while digital billing streamlines internal accounting. Multiple redundancy and extremely high levels of security safeguard the role of the Army as the protector of Germany’s national security. Because it leverages Deutsche Telekom’s nationwide network infrastructure, the T-Systems solution also offers outstanding cost efliciency, particularly in urban areas.
