Chapter 1  
Overview  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are the  
10/100Mbps fast switch single-mode fiber transceivers which can send and  
receive on two different wavelengths (1310nm and 1550nm) on a single-mode  
fiber cable.  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters include the  
following models:  
AT-FS238a/1  
AT-FS238a/2  
AT-FS238b/1  
AT-FS238b/2  
Below is how to differentiate between the models mentioned above:  
AT-FS238a/1 = (1310TX/1550RX) - 15 km range  
AT-FS238b/1 = (1550TX/1310RX) - 15 km range  
AT-FS238a/2 = (1310TX/1550RX) - 40 km range  
AT-FS238b/2 = (1550TX/1310RX) - 40 km range  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are designed  
to extend the distance of your network by converting Fast Ethernet data  
between twisted pair cabling and single-mode fiber optic cabling. These dual-  
port bridging converters can also be used to improve the performance of your  
network by dividing it into smaller, more manageable segments.  
Each bridging converter features a 100Base-FX fiber optic port and a 10Base-  
T/100Base-TX twisted pair port.The fiber optic port has a simplex SC  
(Subscriber Connector) connector and an operating distance of 15 kilometers  
(9.4 miles) or 40 kilometers (24.8 miles), depending on the model. The twisted  
pair port has an RJ-45 connector with a maximum operating distance of 100  
meters (328 feet).

Overview  
The fiber optic port operates at 100 Mbps, while the twisted pair port operates  
at 10 Mbps or 100 Mbps. Both ports feature half- and full-duplex operation.  
AT-FS238a/x and AT-FS238b/x Series Bridging Converters can be installed on  
a desktop or in an AT-MCR12 chassis. These bridging converters are easy to  
install and do not require software configuration or management.  
Note  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are  
designed to be used in pairs; therefore, the AT-FS238a/x fiber port must  
be connected to the AT-FS238b/x fiber port only.

AT-FS238a/x and AT-FS238b/x Series Installation Guide  
Twisted Pair Port  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters have one  
10Base-T/100Base-TX twisted pair port. The twisted pair port features a  
RJ-45 connector.  
Port Speed  
The twisted pair port is compliant with the 10Base-T and 100Base-TX  
standards and is capable of either 10 Mbps or 100 Mbps operation. You can set  
the port speed manually or, since the port is IEEE 802.3u auto-negotiation  
compliant, you can allow the bridging converter to set the port speed  
automatically. With auto-negotiation, the speed of the port is set  
automatically by the bridging converter after it determines the speed of the  
end-node connected to the port. Auto-negotiation is designed to ensure that  
the port on the bridging converter and the end-node are operating at the same  
speed and that they are communicating at the highest possible common speed  
of the devices.  
Duplex Mode  
Duplex mode refers to how an end-node receives and transmits data. If an  
end-node can receive or transmit data, but not both simultaneously, the end-  
node is operating in what is referred to as half-duplex mode. If an end-node  
can both receive and transmit data simultaneously, the end-node is said to be  
operating in full-duplex mode. Naturally, an end-node capable of operating in  
full-duplex can handle data much faster than an end-node that can only  
operate in half-duplex mode.  
The twisted pair ports on the AT-FS238a/x and AT-FS238b/x Series Bridging  
Converter can operate in either half-or full-duplex mode. They are IEEE  
802.3u-compliant and use Auto-Negotiation to set the duplex mode setting for  
you automatically.  
For Auto-Negotiation to operate properly on a bridging converter, the end-  
nodes connected to the converter should also use Auto-Negotiation. If an end-  
node does not have this feature and has a fixed duplex mode of full-duplex, the  
result will be a duplex mode mismatch between the end-node and a converter  
port. A port on the bridging converter connected to an end-node with a fixed  
duplex mode of full-duplex will operate at only half-duplex. This results in the  
end node using full-duplex and the switch port using half-duplex. This can  
produce network performance problems. Should you encounter this situation,  
you must configure the port on the end-node to use Auto-Negotiation or, if it  
lacks that feature, to half-duplex.

Overview  
Auto MDI/MDI-X  
An RJ-45 twisted pair port on a 10 Mbps or 100 Mbps Ethernet network  
device can have one of two possible wiring configurations: MDI or MDI-X. The  
RJ-45 port on a PC, router, or bridge is typically wired as MDI, while the  
twisted pair port on a bridging converter or hub is usually MDI-X.  
To connect two 10 Mbps or 100 Mbps network devices together that have  
dissimilar port wiring configurations, such as MDI to MDI-X, you would  
usually use a straight-through twisted pair cable. To connect two network  
devices that have the same wiring configuration, such as MDI to MDI, you  
would usually use a crossover cable.  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters feature  
automatic MDI/MDI-X. The RJ-45 port automatically determines the  
configuration of the port on the device to which it is connected and then  
configures itself appropriately. For example, if a port on a bridging converter  
is connected to a port on a bridge, which is typically wired as MDI, the port on  
the bridging converter automatically configures itself as MDI-X. This feature  
allows you to use either crossover cables or straight-through cable when  
connecting a device to the twisted pair port.  
Fiber Optic Port  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters have one  
100Base-FX fiber optic port. The single-mode fiber optic port features a  
simplex SC connector.  
Port Speed  
The fiber optic port is compliant with the 100Base-FX standard and has a  
fixed operating speed of 100 Mbps. The end-node connected to the fiber optic  
port on the bridging converter must also be able to operate at 100 Mbps. The  
AT-FS238a/x and AT-FS238b/x Series Bridging Converters can send and  
receive on the two different wavelengths (1310nm and 1550nm). The different  
wavelengths used by these bridging converters are as follow:  
AT-FS238a/x - TX=1310 and RX=1550  
AT-FS238b/x - TX=1550 and RX=1310  
Note  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters are  
designed to be used in pairs; therefore, the AT-FS238a/x fiber must be  
connected to the AT-FS238b/x fiber only.

AT-FS238a/x and AT-FS238b/x Series Installation Guide  
Duplex Mode  
The fiber optic port on the bridging converter can operate in half- or full-  
duplex mode. You must set the duplex mode manually using the DIP switches  
on the back of the unit.  
Mode Selection Button  
Link Test  
The link test is a fast and easy way for you to test the connections between the  
bridging converter ports and the end-nodes that are connected to the ports. If  
a network problem occurs, you can perform a link test to determine which port  
is experiencing a problem, and be able to focus your troubleshooting efforts on  
the cable and end-node where the problem resides.  
A link test is performed when the Mode Selection button is toggled until the  
LNK LED is green.  
Note  
Performing a link test does not interfere with a bridging converter’s  
ability to pass network traffic.  
MissingLink  
The MissingLink feature enables the fiber optic ports on the bridging  
converter to pass the “Link” status of their connections to each other. When  
the bridging converter detects a problem with one of the ports, such as the loss  
of connection to an end-node, the bridging converter shuts down the  
connection to the other port, thus notifying the end-node that the connection  
has been lost.  
For example, if the network twisted pair cable to the 10Base-T/100Base-TX  
port on the bridging converter were to fail, the unit would respond by dropping  
the link on the 100Base-FX fiber optic port. In this way, the bridging  
converter notifies the end-node connected to the fiber optic port that the  
connection on the twisted pair port has been lost. If the failure had started  
with the fiber optic cabling, the unit would drop the link to the twisted pair  
port.  
The value to this type of network monitoring and fault notification is that  
some devices can be configured to take a specific action in the event of the loss  
of connection on a port. In some cases, the unit can be configured to seek a  
redundant path to a disconnected end-node or send out a trap to a network  
management station, and so alert the network administrator of the problem.

Overview  
Note  
MissingLink or Smart MissingLink is disabled when you perform a link  
test. Consequently, to ensure that the MissingLink or Smart  
MissingLink is enabled on the bridging converter, always set the Mode  
Selection button so that the ML or SML LED is green during normal  
network operations.  
Smart MissingLink  
Like MissingLink, the Smart MissingLink feature terminates the link on the  
failed port thereby notifying you when a connection has been lost.  
Additionally, Smart MissingLink indicates on which port the connection has  
failed. This is shown by a blinking LNK LED on the good port.  
For example, if the network twisted pair cable to the 10Base-T/100Base-TX  
port on the bridging converter were to fail, the LNK LED on the 100Base-FX  
fiber optic port will blink, indicating a failed connection on the twisted pair  
port. The fiber optic port is still able to receive a signal.  
The bridging converter notifies the end-node connected to the fiber optic port  
that the connection on the twisted pair port has been lost. If the failure had  
started with the fiber optic cabling, the LNK LED on the twisted pair port  
would blink.  
The value to this type of network monitoring and fault notification is so that  
you can quickly see which port has failed and troubleshoot your network  
accordingly.  
Bridging Converter Performance  
The bridging converters perform at:  
148,800 pps for 100 Mbps and 14,880 pps for 10 Mbps for full wire  
speed forwarding and filtering  
200 Mbps maximum throughput in 100 Mbps, full-duplex mode  
20 Mbps maximum throughput in 10 Mbps, full-duplex mode  
Storage for up to 2k MAC addresses  
280 kB (per port) packet buffer  
Low latency 15.6 µs (64-byte packet, 100 Mbps full-duplex)

AT-FS238a/x and AT-FS238b/x Series Installation Guide  
DIP Switches  
The DIP switches are used to manually configure the operating characteristics  
of the ports. These characteristics include the port speed, duplex mode, and  
auto-negotiation.  
On the 100Base-FX fiber optic port, you can manually set the duplex mode to  
either half- or full-duplex.  
On the 10Base-T/100Base-TX twisted pair port, you can manually set the  
speed of the port to either 10 Mbps or 100 Mbps, set the duplex mode to either  
half- or full-duplex and enable or disable auto-negotiation. Enabling auto-  
negotiation will automatically set the port’s speed and duplex mode.  
MAC Address Table  
Up to 2,000 MAC addresses can be stored in the bridging converter’s MAC  
address table. The bridging converter’s self-learning feature will learn all new  
addresses in real-time after power-up. If the source address of an incoming  
packet is not found in the MAC address table, the bridging converter will  
update the table with the new address.  
The bridging converter also has an automatic address aging feature that will  
delete a source address from the table if it has not seen a frame from the end-  
node with that address within five minutes. This prevents the table from  
becoming filled with addresses of end-nodes that are no longer active.  
The bridging converter forwards all multicast, broadcast, and unicast packets  
when the MAC address table has exceeded its storage limit.  
Store and Forward  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters support store  
and forward switching at Fast Ethernet full-wire speed in 100 Mbps, half- or  
full-duplex mode. Packets entering each port are stored in buffers. Once the  
full packet is received, the bridging converter will forward or discard the  
packet, depending on its destination address and error status. This ensures  
that only error-free packets destined for another segment will be transferred  
across the bridging converter, reducing network load. For example, if the  
packet entering from Port 1 is destined for an end-node on Port 2, the bridging  
converter forwards the frame if the frame does not contain any errors. If the  
packet from Port 1 is destined for an end-node also connected to Port 1, the  
packet is discarded.  
11  
 
     
Overview  
The bridging converter will discard CRC errors, misaligned, runt, and under-  
oversized packets. When the packet has dribble bits at the end, the bridging  
converter will truncate to octet boundary and check for a good FCS before  
forwarding.

Installing the Bridging Converter  
Planning the Installation  
Be sure to observe the following guidelines when planning the installation of  
your bridging converter.  
The AT-FS238a/x and AT-FS238b/x Series Bridging Converters must  
be connected back-to-back; therefore, one AT-FS238a/x and one AT-  
FS238b/x Series converters are required.  
The end-node connected to the 10Base-T/100Base-TX twisted pair  
port can operate at either 10 Mbps or 100 Mbps.  
The end-node connected to the twisted pair port on the bridging  
converter can be a network adapter card, repeater, router, hub, or  
another bridging converter.  
The twisted pair cabling must be kept away from sources of electrical  
noise, such as radios, transmitters, power lines, broadband amplifiers,  
electrical motor, and fluorescent fixtures.
