IEEE 802.3

DESCRIPTION

•

TinyBridge-100 is a high performance,

remote, self-learning Ethernet/Fast Ethernet

bridge. Its small size and low cost make it

ideal for sensitive bridging applications, or

as a LAN extender over synchronous WAN.

LAN INTERFACE

• TinyBridge-100 is available with a

10/100BaseT interface. The interface

operates in full or half duplex Ethernet

topologies.

• TinyBridge-100 supports a packet length of

up to 1536 bytes.

• Automatic MDIX allows using straight or

crossed cables for the LAN connection.

• MAC addresses of the LAN to which the

unit is connected are automatically learnt.

Only those frames destined for the remote

LAN are forwarded. The LAN table stores

up to 2048 addresses and is updated

automatically.

• MAC address filtering can be disabled,

allowing all traffic to flow over the WAN link

• TinyBridge-100 has two queues for

handling priority, determined in the

following order:

 If the packet received is an Ethernet tag

frame, TinyBridge-100 marks the packet

according to the tag priority (0–7).

0–3: low priority queue

4–7: high priority queue

 Otherwise, Tiny

Bridge-100 marks the

packet according to IP-ToS priority (0–7).

0–3: low priority queue

4–7: high priority queue

 U

ntagged and non-IP frames enter the

low priority queue.

Frames egress from the queues with a 1:2

ratio, two frame

s with high priority, one

frame with low priority.

• Flow control for full duplex and

backpressure for half duplex are supported.

The buffer holds up to 120 frames.

WAN INTERFACE

• A selection of synchronous WAN interfaces

is available:

 V.24/RS

-232

 V.35

 V.36/RS

-449

 X.21

 RS-530.

• A fault on the WAN can be propagated if

fault propagation is enabled; the

TinyBridge-100 shuts down the link and

forces a router to trace another route.

• TinyBridge-100 operates over synchronous

links at data rates of up to 10 Mbps. An

external clock can be supplied for

operation at other bit rates.
