Miniature Remote Ethernet Bridge Extender

RAD's TinyBridge-100 miniature remote Ethernet bridge is a remote, self-learning Ethernet bridge used in cost sensitive bridging applications or as a LAN extender over bitstream-type infrastructures. The TinyBridge-100 miniature remote Ethernet bridge is available with a variety of WAN interfaces, including V.24, V.35, V.36, RS-530, and X.21.

• Small size, high performance; provides 10/100BaseT Ethernet connectivity in a palm-sized package

• Simple, plug-and-play installation

• Fault propagation feature minimizes downtime, enabling fast reroute

• Fast return on investment

TinyBridge-100 is a high performance, remote, self-learning Ethernet bridge. Its small size and low cost make it ideal for cost-sensitive bridging applications or as a LAN extender over bitstream-type infrastructures. TinyBridge-100 is available with a variety of WAN interfaces, including V.24, V.35, V.36, RS-530, and X.21.

The device automatically learns MAC addresses on the LAN to which it is connected and forwards only those frames destined for another LAN. Filtering and forwarding are performed at wire speed.

The TinyBridge-100 4-wire option extends the LAN over four wires to 1,300 meters (4,265 ft) when operating at 5 Mbps, and up to 500 meters (1,640 ft) when operating at 10 Mbps. The device can support rates up to 10 Mbps over synchronous links.

The TinyBridge-100 is available with a 10/100BaseT interface and with support of frames up to 1,536 bytes, enabling transparent forwarding of VLAN frames.

The TinyBridge-100 device uses HDLC framing for high utilization of the WAN link. The device does not perform any negotiation over the link. This feature eliminates waste of valuable bandwidth. It also makes the device especially useful for satellite and other wireless broadcast applications. Any variable speed up to 10 Mbps on the link is supported transparently. The link speed may be adjusted “on-the-fly.”

In cases of error conditions on the TinyBridge-100 WAN port, a fault propagation feature will tear down the link integrity on the Fast Ethernet port. This will indicate the error conditions to the Ethernet device connected to the TinyBridge-100 and will enable automatic rerouting of the traffic if required.
