FEATURES
- 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
SPECIFICATIONS

- Link interfaces: V.24, V.35, V.36, RS-530, X.21;
internal fiber optic or 4-wire modems
- Transparent simplex, half duplex or full duplex
support on the WAN interface
- WAN link rate of up to 10 Mbps sync or up to 115.2
kbps async
- 15,000 frames per second filtering and forwarding
rate
- 256-frame buffer
- 10,000 MAC address LAN table
- Automatic learning and aging
- Enhanced TinyGram compression
- No external power supply needed for AUI option

- 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.
