RAD TinyRouter RAD TinyRouter 4W

TinyRouter offers a choice of WAN interfaces, including V.24, V.35, V.36, X.21, RS-530 or a built-in fiber optic modem. The WAN link operates transparently in simplex, half duplex or full duplex modes. TinyRouter-4W extends the LAN over 4-wire to 1300m (4265 ft) when operating at 5 Mbps and up to 500m (1640 ft) when operating at 10 Mbps. Variable link speeds up to 10 Mbps are supported transparently. Link speeds may be adjusted “on-the-fly” without any effect on the TinyRouter or TinyRouter-4W. In addition, they provide hardware-based traffic throughput control.

TinyRouter and TinyRouter-4W are high performance, miniature IP routers. Their small size and low cost make them ideal for cost-sensitive routing applications or as LAN extenders or segmenters over bit-stream type infrastructures.

TinyRouter and TinyRouter-4W work by taking each Ethernet frame from the LAN and determining whether or not the IP packet is destined for the IP network on the Ethernet LAN. If not, they forward the packet to the WAN link. IP packets received on the WAN are automatically forwarded to the LAN if the IP network matches.

The devices include hardware filters that handle all filtering operations at wire speed from both LAN-to-WAN and WAN-to-LAN, without dropping a single packet. Routing is performed at the maximum rate of 30,000 frames per second (wire speed). The buffer can hold 256 full-sized frames with a throughput latency of one frame.

TinyRouter and TinyRouter-4W are available with 10Base5 (AUI) or 10BaseT (UTP) interfaces. The 10BaseT interface can also operate in full duplex Ethernet applications.
