Ethernet Switch

The core of information technology on board of vehicles is the ETHERNET SWITCH.

In our architecture, each car is equipped with one or more multifunction intelligent switches; connection with adjacent cab/coach can be made made with a redundant Ethernet backbone, managed in accordance with IEEE 802.3ad standard for bandwidth aggregation and automatic fault tolerance.

Tattile provides a high performance, fully managed, 2-layer Switch with ARM microprocessor integrated and QoS.

This device is a proprietary solution fully compliant to EN50155 requirements.
