  • TinyBridge is a high performance, remote, self-learning Ethernet bridge. Its small size and low cost make it ideal for sensitive bridging applications or as a LAN extender or segmenter over bit stream type infrastructures.
  • TinyBridge is available with one of two Ethernet interfaces: 10Base5 (AUI) or 10BaseT (UTP). The 10BaseT interface can also operate in full duplex Ethernet topologies. No external power supply is required for the AUI interface.
  • A choice of WAN interfaces is available
  • TinyBridge supports operation of up to 10 Mbps synchronous links or 115.2 kbps asynchronous links. In asynchronous mode, an internal baud rate generator can be used to generate seven standard bit rates within the range of 9.6 kbps to 115.2 kbps. An external clock can be supplied for operation at other bit rates. HDLC-like framing is used in accordance with RFC 1662. See the Installation and Operation documentation for configuration and operation details at different asynchronous link speeds.
  • TinyBridge automatically learns MAC addresses on the LAN to which it is connected and forwards only those frames destined for another LAN. Its LAN table stores up to 10,000 addresses and is automatically updated.
  • Filtering and forwarding is performed at the maximum theoretical rate of 15,000 frames per second (wire speed). The buffer can hold 256 frames with a throughput latency of one frame. Filtering can be disabled for extender or segmenter applications, allowing all traffic to flow over the WAN link.
  • Enhanced TinyGram compression increases data throughput by stripping the padding bits in 64-byte frames. When disabled, frames are transmitted as is
