Innovative products for Ethernet data transmission in applications

Ethernet communication Managed and unmanaged switches for Ethernet communication are available. the DSL technology and the tunnelling capability of the serial protocols make it possible to switch directly from conventional serial Voice Frequency Telegram (VFT) transmission to Ethernet communication while retaining the existing copper wires without having to adapt the serial terminals, e.g. for remote control technology.

Features such as Rapid Spanning Tree Protocol (RSTP), bypass circuits such as those found in UMTS or Tetra modems, and the use of optical communication lines are also available for increased usability.
