Descriptions
BS-2E-01 is a device providing receiving and transmission of Ethernet traffic in E1 stream channels.
The bridge has 4 Ethernet ports, each of them can be connected to one of the 2 E1 ports. The device supports VLAN groups, QoS traffic prioritization.
The connection formed by the device ensures the transparency of all types of packets transmitted in the Ethernet network segments.
BS-2E-01 together with BS4E-3-R bridges installed in regenerator modules can be used for local networking with data transmission via Stream-2 synchronous channels, to connect remote Ethernet network segments, to connect video surveillance systems or measuring systems with the Ethernet interface, to organize Ethernet traffic transit, etc.
