Product Features

RATE CONVERSION

The CBFTF10xx-10x 2-port Ethernet™/Fast Ethernet™ bridging Media
Converter allows connection of 10Mb/s terminal devices on a 10Base-T
legacy Ethernet™ copper network to 100Mb/s terminal devices on a 100Base­TX Fast Ethernet™ copper network and/or to 100Mb/s terminal devices on a
100Base-FX Fast Ethernet™ fiber network.

AUTO-NEGOTIATION

The Auto-Negotiation feature allows the Media Converter to be used with
10Base-T and 100Base-TX twisted-pair ports. Using Auto-Negotiation, the
Media Converter brings up the copper links in the highest speed and mode
possible for all the attached network devices.

If selected, Auto-Negotiation allows a twisted-pair link to become operational
only after the Auto-Negotiation function matches network speed capabilities
at both ends of the twisted-pair copper segment.

AUTOCROSS

The AutoCross™ feature, when selected, allows either straight-through (MDI)
or crossover (MDI-X) cables to be used when connecting to 10Base-TX or
100Base-TX devices, such as hubs, transceivers, or network interface cards
(NICs). AutoCross determines the characteristics of the cable connection and
automatically configures the unit to link up, regardless of the cable
configuration.

DISTANCE EXTENSION

The CBFTF10xx-10x Media Converter segments 10Base-T copper Ethernet
and/or 100Base-TX copper Fast Ethernet and 100Base-FX fiber Fast Ethernet
collision domains.

In a half-duplex Ethernet™ or half-duplex Fast Ethernet™ environment, the
CBFTF10xx-10x Media Converter extends network distances by segmenting
collision domains so that the 10Base-T 5-Segment Rule (see page 12) or the
100Base-TX/ 100Base-FX 512-Bit Rule (see pages 11 and 12) applies
separately to each collision domain.

In a full-duplex Ethernet™ or full-duplex Fast Ethernet™ environment, the
CBFTF10xx-10x Media Converter extends network distances to the physical
cable limitations imposed by the selected twisted-pair copper fiber cables (see
pages 9 and 10).

CONGESTION REDUCTION

The CBFTF10xx-10x Media Converter does not forward collision signals or
error packets from one collision domain to another, improving baseline
network performance. In addition, the bridging Media Converter filters
packets destined for local devices, also reducing network congestion.

LINK PASS-THROUGH

When the Link Pass-Through feature is activated, a fault on one side of the
Media Converter stops the signal and data transmission on the other side of
the Media Converter. If the Media Converter does not detect a good link on
the copper side, the Media Converter disables all transmission (including
active-idle) on the fiber side.

INSTALLATION

Set the DIP Switches

The DIP switches are located on the circuit board of the Media Converter. Use a
small, flatblade screwdriver or a similar device to set each DIP switch.

NOTE: DIP switch numbers 1, 2, 3, and 5 apply to the twisted-pair copper
connector. DIP switch number 4 applies to the fiber connector. DIP switch
number 6 applies to the Media Converter.

1. Twisted-Pair Auto-Negotiation

UP (Enabled) - The Media Converter
“advertises” ALL rate and mode capabilities to
the network:

• 100Mb/s full-duplex,

• 100Mb/s half-duplex,

• 10Mb/s full-duplex, and

• 10Mb/s half-duplex.

DOWN (Disabled) - The bridging Media Converter does not “advertise” the rate
and mode capabilities to the network. Switch #2 and switch #3 are then used to
set the twisted-pair rate and mode.

2. Twisted-Pair Rate

UP - Sets the twisted-pair rate to 100Base-TX.

DOWN - Sets the twisted-pair rate to 10Base-T.

3. Twisted-Pair Mode

UP (Full-Duplex):

The twisted-pair cable distances are constrained
by the cable requirements (see page 10).

DOWN (Half-Duplex):

At the 100Base-TX rate, the twisted-pair cable
distances are constrained by the 512-Bit Rule
(see page 11).

At the 10Base-T rate, the twisted-pair cable distances are constrained by the 5­Segment Rule (see page 12).

HALF-DUPLEX NETWORK

512-Bit Rule - 100Base-TX or 100Base-FX

Use the 512-Bit Rule to calculate the 100Base-TX or 100Base-FX half-duplex
collision domain.

In a half-duplex network, the maximum cable lengths are determined by the
round trip delay limitations of each Fast Ethernet™ collision domain. (A
collision domain is the longest path between any two terminal devices, e.g. a
terminal, switch, or router.)

The 512-Bit Rule determines the maximum length of cable permitted by
calculating the round-trip delay in bit-times (BT) of a particular collision
domain. If the result is less than or equal to 512 BT, the path is good.

To calculate the round-trip delay for a collision domain:

1. Find the collision domain, i.e. the longest
path between any two terminal devices
(e.g., terminal, switch, and/or router).

2. Calculate the round-trip delay in bit-times
for each length of cable.

4. Determine the bit-time values for each
device (see table to the right).

3. Add the bit-time values for each length of
cable and the bit-times for each device.

NOTE: The 512-Bit Rule applies separately to each collision domain.

100BASE-TX TWISTED-PAIR EXAMPLE

In the example below, the CBFTF10xx-10x 2-Port Bridging Media Converter
acts as a switch. In this case, the collision domain bound by the Media
Converter on one end and a terminal on the other.

Since the total of the bit-times in this example is less than 512 (see chart
below), the path is good.

100 meters TP

Class II Hub

Sum of the bit-times for the example collision domain:

Media Converter = 50.0 BT
100 m TP cable (100m x 1.11 BT/m) = 111.0 BT
Two Class II hubs (2 x 92) = 184.0 BT
Two 10 m TP cables (2 x 10m x 1.11 BT/m) = 22.2 BT
Terminal = 50.0 BT

Total = 417.2 BT

Class I hub 140 BT
Class II hub 92 BT
terminal/router 50 BT
1 meter TP cable 1.11 BT
1 meter fiber cable 1 BT
Fast Ethernet switch 50 BT

CBFTF10xx-10x 50 BT

HALF-DUPLEX NETWORK

100BASE-TX FIBER EXAMPLE

The drawing to the right
illustrates a collision domain
where two Media Converters
are connected via fiber cable.

Since the total of the bit-times
in this example is less than
512 (50BT + 400BT + 50BT =
500BT) the path is good.

5-Segment Rule - 10Base-T

Use the 5-Segment Rule to calculate the 10Base-T half-duplex collision
domain.

The 5-Segment rule states that a transmission path of a collision domain can
consist of no more than 5 segments. A “collision domain” and a “segment”
are defined as follows:

A collision domain is the longest path in a 10Base-T network between any
two terminal devices, e.g. a terminal, switch, or router. The SPBFT10xx-10x
2-Port Bridging Media Converter is also a terminal device.

A segment is a cable connection
between any two network interfaces
within a collision domain.

10BASE-T TWISTED-PAIR EXAMPLE

The example to the right illustrates
applying the 5-Segment Rule. The cable
between each network device (Media
Converter, Hub, or Terminal) is
numbered as a “segment”.

Note that the longest transmission path
(from the Media Converter at the top to
the terminal at the bottom) is 5 segments.
Therefore, the network in this example
complies with the 5-Segment rule.

NOTE: The 5-Segment Rule must be
applied separately to each 10Base-T
collision domain.

FAULT ISOLATION AND RECOVERY

If the Media Converter fails, isolate and correct the failure by determining the
answers to the following questions and then taking the indicated action:

1. Is the power LED on the Media Converter illuminated?
NO

• Is the media converter inserted properly into the chassis?

• Is the power cord properly installed in the chassis and at the external

power source and does the external power source provide power?

• Contact Technical Support: US/Canada: 1-800-260-1312,

International: 00-1-952-941-7600.

YES

• Proceed to step 2.

2. Is the Link LED illuminated on a port with twisted-pair installed?
NO

• Check the copper cables for proper connection and pin assignment.

• Contact Technical Support: US/Canada: 1-800-260-1312,

International: 00-1-952-941-7600.

YES

• Proceed to step 3.

3. Is the Link LED illuminated on a port with fiber installed?
NO

• Check the fiber cables for proper connection.

• Verify that the TX and RX cables are connected to the RX and TX

ports, respectively, on the 100Base-FX device.

• Contact Technical Support: US/Canada: 1-800-260-1312,

International: 00-1-952-941-7600.

YES

• Contact Technical Support: US/Canada: 1-800-260-1312,

International: 00-1-952-941-7600.

4. Is the Link in the proper position?
NO

• In LPT mode, forced 10/100 Mb mode, the link “flaps” (link up -->

link down) when the link is lost.

• In Software mode if FEF is disabled, the converter is in forced 10/100

mode, and LPT is enabled, "flapping" may occur during loss of link.
To remedy the situation enable FEF.

• (In Hardware mode FEF is enabled by default.)

• Refer to Tech Tips available at: http://www.transition.com

YES
