Network infrastructure modernisation for a municipal public transport company

A municipal transport company providing public transport operates continuously, 24 hours a day, 7 days a week. Fleet management, timetable coordination, ticketing systems, monitoring and communication between field units all rely on smoothly running IT infrastructure.

The most important requirement was operational continuity. Any network outage could directly translate into disruptions to passenger service and the operation of critical systems.

The environment was distributed and varied. The infrastructure had to serve many locations, different throughput requirements and PoE-powered devices, including cameras, VoIP phones and access points.

The IT department needed not only hardware, but also deployment support and the knowledge to maintain the new infrastructure independently.

A comprehensive modernisation based on enterprise-class DCN switches was carried out. Medium-traffic nodes used the DCN S5750E-26X-SI-R2, while higher-traffic locations used the DCN S5750E-52X-P-SI-R2 and DCN S5750E-52X-SI-R2 models.

In locations requiring end-device power, the DCN S5750E-28X-P-SI-R2 and DCN S5750E-28X-SI-R2 models were used, enabling support for IP cameras, VoIP phones and Wi-Fi access points.

The deployment was complemented by DCN technical training for the company's IT staff.

The new DCN infrastructure reduced the risk of downtime for critical transport-management and monitoring systems. A single platform across the whole organisation made it easier to manage the network in all locations.

PoE support simplified cabling and allowed cameras and access points to be powered directly from the network. Knowledge transfer to the IT team increased self-sufficiency in day-to-day administration.

The project shows that modernising the infrastructure of a 24/7 organisation requires not only good hardware, but also a proven deployment and support model.
