Product Features

Rate Conversion

The media converter allows connection of 10Mb/s terminal devices on a
10Base-T legacy Ethernet copper network to 100Mb/s terminal devices on a
100Base-TX fast Ethernet copper network.

Auto-Negotiation

The Auto-Negotiation feature allows the CBFTF10xx-10x media converter to
automatically configure itself to achieve the best possible mode of operation
over a link. The media converter broadcasts its speed (10 Mb/s or 100 Mb/s)
and duplex capabilities (full or half) to the other devices and negotiates the
best mode of operation. Auto-Negotiation allows quick and easy installation
because the optimal link is established automatically.

A scenario where the media converter is linked to a non-negotiating device is
a case where the user may want to disable Auto-Negotiation. In this instance,
the mode of operation will drop to the least common denominator between
the two devices (e.g.: 10 Mb/s, half-duplex). Disabling this feature gives the
user the ability to force the connection to the best mode of operation.

AutoCross™

When the AutoCross feature is activated, it allows either straight-through
(MDI) or crossover (MDI-X) copper cables to be used when connecting to
10Base-T or 100Base-TX devices. AutoCross determines the characteristics of
the connection and automatically configures the unit to link up, regardless if
the copper cable is MDI or MDI-X configuration. (Transition networks
recommends leaving the device in the default “enable” mode.)

Link Pass-Through

The Link Pass-Through feature allows the media converter to monitor both the
fiber and copper RX (receive) ports for loss of signal. In the event of a loss of
an RX signal (1), the media converter will automatically disable the TX
(transmit) signal (2), thus, “passing through” the link loss (3). The far-end
device is automatically notified of the link loss (4), which prevents the loss of
valuable data unknowingly transmitted over an invalid link.

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 fast Ethernet environment, the CBFTF10xx-10x
media converter extends network distances by segmenting collision domains
so that the 5-Segment Rule (see page 10) or the 512-Bit Rule (see pages 9 and

10) applies separately to each collision domain.

In a full-duplex Ethernet or fast Ethernet environment, the CBFTF10xx-10x
media converter extends network distances to the physical cable limitations
imposed by the selected copper and fiber cables (see pages 1 and 2).

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 media converter filters packets
destined for local devices, also reducing network congestion.

SNMP

See the on-line documentation that comes with Transition Networks
FocalPoint™ software for applicable commands and usage.

Use SNMP at an attached terminal or at a remote location to monitor the
media converter by monitoring:

• Media converter power

• Fiber link status

• Copper link status

• Copper port speed

• Hardware switch settings.

Also, use SNMP to enter network commands that:

• Enable/disable Auto-Negotiation on copper

• Force 10Mb/s or 100Mb/s on copper

• Force full-duplex or half-duplex on copper

• Force full-duplex or half-duplex on fiber

• Select advertised modes (when Auto-Negotiation is enabled)

• Enable/disable pause

• Enable/disable Link Pass-Through

• Enable/disable Far End Fault

• Group control string

• Source address change

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.

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 -- Continued

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 CBFTF10xx-10x
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.
