Overview

The 4E1-4ETH Protocol Converters (Ethernet over TDM) are capable to support four network devices or other devices for remote centralized management. Remote users can perform centralized management for 4E1-4ETH series devices by Telnet, WEB Server or centralized management software. It also can remotely perform such actions like restart and upgrade the 4E1-4ETH series devices; The device also can be managed by local console mangement.

The devices are widely used for remote management of devices room, servers, routers and other key equipment in the situation of industrial control, water treatment, radio and television, public facilities and unattended room management.
