• Synchronous WAN interfaces: V.24,

V.35, V.36, RS-530, X.21, or 4-wire
modem

• Two priority queues according to

802.1p or IP ToS bits

• Fault propagation of WAN error

conditions to LAN port

• Automatic MDIX support

• Compatible with applicable parts of

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, TinyBridge-100 marks the

packet according to IP-ToS priority (0–7).
0–3: low priority queue
4–7: high priority queue

 Untagged and non-IP frames enter the

low priority queue.
Frames egress from the queues with a 1:2
ratio, two frames 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.

Connecting the LAN Interface

• Connect the user LAN to the RJ-45

connector of TinyBridge-100. Automatic
MDIX allows using straight or crossed
cables for the LAN connection.

Connecting the WAN Interface

• Connect the 25-pin female connector

of the unit to DCE equipment, using the
supplied adapter cables (see Table 3,
Table 4, or Table 5 for pinout details)

Connecting the 4-Wire Interface

Warning: Do not apply power to the TinyBridge-100
until the 4-wire terminal block is connected as
described below.

1. Remove the protective cover from the
terminal block.

2. Unplug the terminal block from the
TinyBridge-100.

3. Feed the 4-wire cable through the protective
cover and connect the Tx and Rx wires to
their respective terminals, as illustrated in
Figure 7. If the cable is shielded, connect the
shield to the GND terminal.

4. Check that the wires are secure and
reconnect the terminal block to its socket.

5. Place the protective cover in position over
the terminal block.

IMPORTANT: When two 4-wire
TinyBridge-100 units are to be connected
directly, the terminal blocks should be wired
so that the Rx terminals of each
TinyBridge-100 connect to the Tx terminals
of the other unit.
