AutoCross jumper

The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X)
cables to be used when connecting to 10Base-T, 100Base-TX, or 1000Base-T
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.

The AutoCross jumper is located on the circuit board of the media converter (labeled
NA = No Autocross and A = AutoCross). See Jumper positions below.

Note: Use small, needle-nose pliers to set the jumper.

A Either straight-through or crossover cable can be

used for all twisted-pair copper links.

NA Straight-through or crossover twisted-pair cable,

depending on installed site devices, MUST be
installed at EACH twisted-pair copper link.

Note: Factory default is “A” enabled. Transition Networks recommends leaving

the device in the “enable” mode.

Hardware/software jumper

The hardware/software jumper is located on the circuit board (labeled H and S—
see figure to the right.)

Note: Use small needle-nose pliers to set the jumper.

Hardware The media converter mode is determined by the

6-position switch settings.

Software The media converter mode is determined by the

most-recently saved, on-board microprocessor
settings.

Product features

Auto-Negotiation

The Auto-Negotiation feature allows the CGFEB10xx-12x media converter to
automatically configure itself to achieve the best possible mode of operation over a
link. The media converter broadcasts its speed (10 Mbps, 100 Mbps, or 1000 Mbps)
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. No user intervention is required to
determine the best mode of operation.

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.
100 Mb/s, half-duplex). Disabling this feature gives the user the ability to force the
connection to the best mode of operation.

Note: The CGFEB10xx-12x and SGFEB10xx-12x also support 1000 Mbps fiber

Auto-Negotiation.

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.

Full-Duplex Network

In a full-duplex network, maximum cable lengths are determined by the type of
cables that are used. See pages 1 and 2 for the cable specifications for the different
CGFEB1xxx-1xx models.

The 512-Bit Rule does not apply in a full-duplex network.

Half-Duplex network (512-Bit Rule)

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.

For more information on the 512-Bit Rule, see the white paper titled “Collision
Domains” on the Transition Networks website at: www.transition.com.

Pause

The pause feature is used to suspend data transmission temporarily in order to
relieve buffer congestion. If a media converter needs some additional time to clear
network congestion, it will send a pause signal to the media converter at the other
end, that media converter will wait a predetermined amount of time before re­transmitting data. This feature reduces data bottlenecks, allowing for more efficient
use of the network devices while preventing the loss of valuable data.

In Software mode, the pause feature can be set to one of four settings:

• Disable (i.e., no pause)

• Symmetrical pause

• Asymmetric TX (transmit) pause

• Asymmetric RX (receive) pause

Note: Enable the pause feature if it is present on ALL network devices attached to

the media converter(s). Otherwise, disable the pause feature.

AutoCross™

The AutoCross feature allows either straight-through (MDI) or crossover (MDI-X)
cables to be used when connecting to 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.

Automatic link restoration

The converter will automatically restore the link between networked devices after a
fault condition has been corrected. In contrast, products from competitors require
the user to power down, then power up the converters after a fault condition has
been corrected.

IEEE802.1q VLAN tagging and double tagging (Q in Q)

The 802.1Q specification establishes a standard method for inserting virtual LAN
(VLAN) membership information called tagging Ethernet frames to break large
networks into smaller parts or to address security concerns. Q in Q support simply
adds another layer of IEEE 802.1Q tag to the 802.1Q tagged packets that enter the
network. The purpose is to expand the VLAN space by tagging the tagged packets,
thus producing a "double-tagged" frame.

VLAN tagging can be configured to one of the following settings:

• Normal = frames are unmodified when passing through the converter

• Untag = all tagged frames will have their tag removed when passing through
converter

• Tag = all untagged frames are tagged with the source port default VLAN ID

• Double Tag = all egress frames are double tagged using the source port default
VLAN ID for the extra tag. This also enables ingress double tag removal.

Ingress:

a. Frame does not contain a tag, frame is not modified
b. Frame contains one 802.3ac tag, tag is removed
c. Frame contains two 802.3ac tags, the first tag is removed

Egress:

a. Frame is untagged, tag is added
b. Frame contains one 802.3ac tag, tag is added before the current one

becomes the frames new 802.3ac tag

IEEE802.1p QoS, IPv4 ToS/Diffserv, IPv6 Traffic class

The 802.1p specification is an extension of the IEEE 802.1Q standard and works in
tandem to define the prioritization of the Ethernet frame for traffic class expediting
and dynamic multicast filtering. IEEE 802.1p establishes eight levels of priority (0
~ 7) with 7 being the highest priority. Each egress Ethernet frame can be prioritized
using IEEE 802.1p (MAC level) Traffic Class, or IPV4 TOS and/or DiffServ and/or
IPV6 Traffic Class.

Bandwidth allocation

It allows setting the bandwidth in varied increments, starting at 64 Kbps to full
bandwidth.

Rate limiting based on frame priorities can also be configured. Each higher priority
frame can be configured to get twice the bandwidth of lower priority frames; e.g.,
priority “3” frame configurations can get twice the bandwidth of priority “2”
frames.

Egress bandwidth allocation in 64Kbits/sec increments:

• Rate limit all frames

Ingress bandwidth allocation in 64Kbits/sec increments with four filter selections:

• Rate limit all frames

• Rate limit multicast, flooded unicast, and broadcast

• Rate limit multicast and broadcast

• Rate limit broadcast

Port-Based VLAN

Allows secure traffic forwarding in one direction only.

RMON Counter on each port

RMON statistics such as packet size counters, collision errors, and packet type are
kept for each port.

Switch selectable speed

On unshielded twisted pair (UTP) when Auto-Negotiation is disabled, the speed can
be set in either software or hardware mode.

Virtual cable test (VCT) on UPT port

The VCT feature utilizes Time Domain Reflectometry (TDR) technology to
remotely and non-evasively diagnose the quality and characteristics of the attached
cable plant. Using this technology, the devices detect and report potential cabling
issues such as cable opens, cable shorts or any impedance mismatch in the cable
and then accurately report (within one meter) the distance of the fault. In addition,
the VCT technology will detect pair swaps, pair polarity reversal, and excessive pair
skew.

DMI Tx Power Alarm Alarm status of measured transmit power.

Rx Power Intrusion
Threshold

Instructs the converter to stop passing traffic when the receive
power drops below the new threshold. This feature is
sometimes referred to as 'Intrusion Detection,' since tapping
into a fiber to intercept traffic leads to a reduction in receive
power. This value can be entered in microwatts or in decibels
relative to 1mW.

Note: This feature is not available on all devices.
