Ethernet bridge


Ethernet bridge Features:
  • LAN interface 100Base-T
  • Serial interface V.35, RS-530, RS-232 или X.21
  • VLAN support
  • Packet size up to 1600 bytes
  • LAN table size: 15000 MAC addresses
  • Data rate up to 10 Mbit/sec
  • Automatic protocol detection and adaptation
  • Cisco compatibility

It forms a high-performance self-learning Ethernet Remote Bridge intended for expansion and interconnection of LANs over infrastructures of solid bit flow type.

The bridge automatically memorizes MAC addresses of the LAN it connects to, and it uses wide-area network links to forward those frames only destined for the outside of the LAN. The address table can store up to 15,000 LAN addresses providing automatic update capabilities. The buffer can contain up to 256 frames.

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
