Gossau School, Canton of Zurich - Implementation of a managed service

Gossau School, in the Canton of Zurich, is spread across 13 sites. Bouygues Energies & Services implemented a managed service to provide an optimally networked communications solution for the school. Among other things, the mandate included centralising the entire telephony solution and securing workstations for employees working from home on a PC or mobile phone via a unified communication client.

Gossau School has 13 sites distributed across a very large municipal area, so integrating all of the sites and implementing a managed service was a priority for us. The solution proposed by Bouygues Energies & Services won us over and meets our requirements.

The customer

The extensive Gossau municipality in the Zurich Oberland has around 10,300 inhabitants and is made up of the villages of Bertschikon, Grüt, Ottikon, Herschmettlen and Gossau-Dorf. Gossau School encompasses primary schools, nurseries, student clubs and the secondary school across a total of 13 locations. Developing and integrating these sites, which are spread across the municipal area, is a major challenge for the school. The school commissioned ICT specialists from Bouygues Energies & Services in Switzerland to implement infrastructure that would meet its requirements.

The task

On behalf of Gossau School, Bouygues Energies & Services implemented a managed service to provide an optimally networked overall communications solution. The mandate also included the centralisation of the entire telephony solution for the 13 locations into one system. The school needed a stable, high-availability system that could guarantee an excellent level of reliability. The list of requirements also included ensuring that people could work from home on PCs or mobile phones via a standardised unified communication client.

The solution

The main factors in determining the new telephony solution were availability, expandability, cutting-edge technology and calculable costs. An evaluation of the starting situation revealed that this could only be done by applying a greenfield approach and the latest voice-over-IP technology. Bouygues Energies & Services then put together a solution proposal based on a managed communication service (MCS) and submitted it to the Gossau school as part of a presentation.

Cutting-edge technologies

A central, redundant call server connected to the public telephone network was implemented in order to substantially reduce maintenance costs. The centralised architecture incorporates all critical components of this communications platform. For school administration staff, the unified communication client offers a convenient way of working from home or on the go. The customer works with IP end devices at all locations, which makes it much easier to move individual devices without incurring any costs. Regular updates of the entire communications solution ensure that the customer always has updated infrastructure at their command. Extensions to the communications solution can be implemented quickly and easily.
