INFORMATION

Overview

BD-2E1-2ETH-CON is multiservice node ring network system equipment is the highly integrated access devices with the bandwidth share function. The 2E1 device can realize two RS-232/485 and 2 Ethernet over 2 channel E1 aggregation transmission. The Ethernet interfaces in different nodes can consist a shared Ethernet switch.

The device can be used as Point to point application or used with central multi-service device as chain network or ring network. The 2E1 convergency device can meet customers’ kinds application by flexible, economical, maintenance application.It can be widely used in a variety of environments capture the telecommunications, electricity, water, finance, transportation, mining, public security and other data transmission services.
