INTRODUCTION

1.4 FDSE TECHNOLOGY OVERVIEW

1.4.1 Why Full-Duplex Switched Ethernet?

The E2200 Series adapters can operate in both Standard Ethernet
mode, and Full-Duplex Switched Ethernet mode. There are many
benefits to be gained from operating in Full-Duplex Switched
Ethernet (FDSE) mode. Full-Duplex Ethernet operation can double
the throughput of an existing system while eliminating rewiring
costs, as it doubles network speed from 10 Mbps to 20 Mbps.

Full-Duplex operation is a prerequisite to the interactive,
multimedia network applications of the future. In pursuit of this
goal, Cabletron Systems is participating in the standards process
with the Full-Duplex Switched Ethernet Consortium (FDSEC), to
create an industry standard that will allow various manufacturer’s
products to coexist in twisted pair and fiber optic networks which
will have an aggregate bandwidth of 20 Mbps.

When increased bandwidth is required, users with E2200 Series
adapters will be able to simply upgrade their shared-access
10BASE-T hubs to Full-Duplex Switched Ethernet hubs. No other
hardware changes will be required at the Network Interface
Controller (NIC) end of the Ethernet links to operate in Full
Duplex Switched Ethernet mode.

In order to provide a full-duplex service based on existing IEEE

802.3 architecture, these prerequisites must be met:

• The network fabric must be a switched-access medium.

• The physical media must provide two channels (Transmit and
Receive).

• The full-duplex 802.3 network must be run over shielded
twisted pair (STP), unshielded twisted pair (UTP), or fiber
optic cable. A switching hub must be used (for three or more
nodes) to interconnect the full-duplex segments.

Page 1 - 6

INTRODUCTION

In order to implement FDSE, we must define three key
components: the operation of the MAC layer entity, the operation
of the MAU, or transceiver, and the operation of an Auto-Detection
mechanism (for Auto-Detect of FDSE).

The most important, and fundamental requirement for FDSE is
that FDSE technology be backward-compatible with standard

802.3 Ethernet technology.

1.4.2 MAC Layer

The Full Duplex Switched Ethernet MAC layer allows for the
simultaneous reception and transmission of 802.3 Ethernet frames.
The entire MAC layer provides separate processing paths for the
transmitter and receiver, including separate CRC generation and
checking. The decision to operate in full-duplex mode will be
made by the FDSE Auto-Detect mechanism.

1.4.3 MAU Operation

The MAU, or transceiver, will signal the MAC layer that FDSE
mode of operation is desired when either of two events occurs: a
“Hardware” register is set on the MAU, or an FDSE Auto-Detect
mechanism indicates that FDSE operation is desired, and switches
hardware to FDSE mode.

When the MAU detects that FDSE operation is desired, it will do
three things: disable the standard Ethernet Collision detector and
the collision LED, disable the loopback signal, and disable the SQE
signal.

These changes are required for the following reasons: collision is
impossible within FDSE, and future AUI transceivers will have
support for FDSE.

Page 1 - 7

INTRODUCTION

1.4.4 FDSE Cabling

FDSE will run on existing category 3 and category 4 UTP cabling.
There is no need to change cable media to upgrade to FDSE
technology.

However, for new wiring plant designs, category 5 cabling will
allow upgrading to 100 Mbps Ethernet operation in the future.

Category 5 UTP cable is specified for desktop wiring distances up
to 100 meters and data rates up to 100Mbps.

Two Technical System Bulletins (TSB) were issued by EIA/TIA
after ANSI EIA/TIA 586.

• TSB-36 classifies UTP cables into categories 3, 4, and 5, and
provides characteristic and performance values at particular
data rates.

• TSB-40 classifies connector hardware (punch-down blocks,
patch panels, wall jacks, etc.) into categories 3, 4, and 5, and
also provides characteristic and performance values at
particular data rates.

Anyone considering installing a new cable plant should consult all
three documents. They are available through your local EIA
publications office - call 1-800-854-7179.

Cabletron Systems is committed to delivering FDSE products in
strict conformance with industry standards and Cabletron’s
Integrated Network Architecture (INA).

2.5.1 Using LANVIEW LEDs

The E2200 series network adapters employ four LANVIEW LEDs.
The functions of these LEDs are explained below:

Transmit Data (green)

The Transmit Data LED flashes when Ethernet packets are being
transmitted by the adapter onto the network.

Receive Data (yellow)

The Receive Data LED flashes when Ethernet packets are being
received from the network.

Collision Present (red)
The Collision Present LED flashes (in Standard Ethernet Mode
only!) when collisions are being detected on the network. This

LED does not function when the E2200 series adapter is in Full­Duplex Switched Ethernet mode.

Link OK (green)

This LED illuminates to indicate that a link has been established
with another Ethernet device on the network segment. This LED
remains lit as long as the link is maintained on the network.

INSTALLATION

2.6 LOADING NETWORK SOFTWARE

You must install the proper network software in order to use your
PC, with the E2200 series adapter, to communicate on the Ethernet
network. Network operating system software drivers are supplied
on the Cabletron software diskette that accompanied the adapter.

The drivers are grouped in subdirectories that contain readme files
to explain recent changes in procedure, etc. The Network Software
Installation Guide, included with the Cabletron software
diskette(s), contains detailed instructions for installing network
drivers.

The E2200 series adapters contain configuration information,
stored in EEPROM. The adapters are shipped with a set of default
parameters already installed. Table 2-1, on the following page, lists
the default parameters.

If these parameters are acceptable, no further configuration of the
adapter is necessary and you may proceed to install network
drivers (see the Network Software Installation Guide for
instructions on installing drivers.

If you wish to change the default parameters in your

NOTE

adapter, you MUST configure it before loading network
drivers. See Section 2.6.1, QuickSet™ Configuration
Utility.

2.6.1 The QuickSet™ Configuration Utility

The E2200 series Ethernet adapters do not have configuration
switches or jumpers; the configuration information is written into
the adapter at the factory. You can use the Cabletron QuickSet
configuration utility to change the default configuration
parameters.

QuickSet is a user-friendly, menu-driven application that lets you
customize the configuration of I/O port address, DMA channel,
media port, hardware interrupt level, boot ROM address, and
memory access speed, for the E2200 series adapters. The following
section contains a brief description of the operation of the QuickSet
utility.

CHAPTER 3

SECONDARY MEDIA

This section contains instructions for connecting your adapter’s
secondary media port to an Ethernet network. The adapter’s
secondary media port can be connected to the Ethernet network
via any of the following means: a second 10BASE-T link, a Thin­Net coaxial connection, a fiber optic link, a wireless hub, or an AUI
port and an external Ethernet transceiver.

You should have selected the port to use during the configuration
procedures. If you did not, run the QuickSet configuration utility
on the Cabletron Software diskette. See Section 2.6.1, The
QuickSet Configuration Utility, for more detailed instructions.

We recommend that you run the diagnostic program before
connecting your PC to a network segment. You can run the
diagnostic program from your backup copy of the Cabletron
Software diskette.

If you wish to run the diagnostic program, you
must make sure that no E22XX network drivers are

!

CAUTION

3.1 CONNECTING TO A THIN-NET SEGMENT

To connect a thin coaxial 10BASE-2 segment to an adapter with a
BNC port, attach a BNC tee-connector (see Figure 3-1, on the
following page) to the adapter’s BNC port.

loaded. Make sure drivers are not being autoloaded
by your system.

If you encounter problems running diagnostics,
power cycle your computer. You may load E22XX
drivers when diagnostics are completed.

Slip the female end of the BNC tee connector over the (male) BNC
port. Then, line up the tee connector slots with the pins on the port
connector.

Page 3 - 1

SECONDARY MEDIA

Push the tee connector in until you engage the pins and rotate the
tee connector clockwise until it locks.

Next, attach the thin-net segment (see Figure 3-1) to one of the
male connections on the BNC tee-connector. Rotate and lock the
collar on the Thin-Net segment, as above.

Each segment attached to the tee-connector must be terminated (at
an end point). If a segment is not attached to (the other) of the male
connections on the tee-connector, then a terminator (see
Figure 3-1,View A) must be placed on that connection.

Attach another thin-net segment (see View B) or a terminator
(View A) to the other male connection on the tee-connector.

HAZARD WARNING

For safety, only one end of a thin-net segment
should be connected to earth ground. Connection
to earth ground at more than one point on the
segment can allow the occurrence of dangerous
ground currents.

3.2 CONNECTING TO AN EXTERNAL TRANSCEIVER

3.2.1 AUI Port

Any adapter with an AUI port can be connected to the network via
an external transceiver and an AUI cable. The AUI port should
have been selected during adapter configuration procedures.

Figure 3-2. Connecting an AUI Cable

Page 3 - 3

SECONDARY MEDIA

To connect an AUI cable to your adapter, attach an external
transceiver to the network segment to which the adapter is going
to be attached. Refer to the applicable transceiver manual. Attach
the female end of an AUI cable, no more than 50 meters in length,
to the transceiver.

Attach the male connector on the AUI cable to the adapter’s AUI
port and tighten the securing screws.

3.3 CONNECTING TO A FIBER OPTIC LINK

The physical communication link consists of two fiber optic
strands between the adapter and the other Ethernet fiber optic
device on the link: Transmit (TX) and Receive (RX).

The adapter Tx connects to the Rx of the Ethernet device. The
adapter Rx connects to Tx of the Ethernet device.

Page 3 - 4

SECONDARY MEDIA

We recommend that you label the fiber optic cable to indicate
which fiber is Receive and which is Transmit. When you buy fiber
optic cable from Cabletron Systems, it is labeled so that at one end
of the cable the fiber is labeled 1, and the other fiber is labeled 2.
This pattern is repeated at the other end of the cable.

ST type fiber optic connectors attach to ST ports in the same way
that BNC connectors attach to BNC ports. You slide the connector
into the port with the alignment key on the connector inserted into
the alignment slot on the port. Then turn the connector until it is
locked in place (see Figure 3-3, below).

Do not touch the ends of the fiber optic strands and do not let
the ends come in contact with dust, dirt, or other
contaminants. Contamination of the ends can cause data
transmission problems. If the ends become contaminated,
clean them with denatured alcohol using a soft, clean, lint
free cloth. If this does not work, use a fiber optic polishing kit
to polish the end of the strand.

Page 3 - 5

SECONDARY MEDIA

To connect a fiber optic segment, attach the fiber labeled 2 to the
adapter’s Transmit port (light gray). Attach the fiber labeled 1 to
the adapter’s Receive port (dark gray).

At the other end of the fiber optic cable, attach the fiber labeled 1 to
the Transmit port of the applicable device. Attach the fiber labeled
2 to the Receive port of the applicable device. At this time you
should check to see that the adapter’s Link LED is lit. If the LED is
not lit, verify that power is on for the PC, and check that the power
is on for the device at the end of the fiber optic cable.

Verify that the fiber optic strands are “crossed over” at the far end
device, Transmit to Receive by checking the labeling on each
strand. Verify that the fiber connection meets the dB loss
specifications outlined in Appendix A, Technical Specifications. If
a link still has not been established, contact Cabletron Systems
Technical Support (see Section 1.2, Getting Help).

A.1.2 Twisted Pair Requirements

Length

10BASE-T transceivers must be able to transmit over a 100
meter link (328 feet) using 24 AWG unshielded twisted pair
wire. 10BASE-T specifies no maximum link length.

Due to cable delay, the maximum link length is always

NOTE

limited to about 200 meters (656 feet), regardless of the type
of cable.

Generally, you can achieve links of up to 150 meters (492 feet)
for unshielded and shielded twisted pair cable. For each
connector or patch panel, subtract 12 meters (39.4 feet).

Page A - 2

TECHNICAL SPECIFICATIONS

This allows links of up to 126 meters (413.4 feet) using standard
24 AWG UTP wire and two patch panels. Higher quality, low
attenuation cables may be required if you want to use links
greater than 126 meters.

Insertion loss

The insertion loss is 11.5 dB maximum for 10BASE-T links at all
frequencies between 5.0 and 10.0 MHz. This includes
attenuation of cables, connectors, patch panels, and reflection
losses due to impedance mismatches.

Impedance

Unshielded twisted pair cable is typically between 85 and
110 ohms. Shielded cable, such as type 1 cable, is typically
150 ohms which can increase the signal reflection. Cabletron
Systems 10BASE-T twisted pair products will work on
shielded twisted pair cable with 75 to 165 ohms impedance.

Jitter

Not more than 5.0 nanoseconds for a 10BASE-T link.

Delay

Must not exceed 100 nanoseconds for a 10BASE-T link.

Crosstalk

Crosstalk is caused by signal coupling between cable pairs
within a multi-pair cable bundle. Crosstalk should not be a
problem if the cable meets all other requirements.

Noise

Noise can be caused by either crosstalk or externally induced
impulses. Impulse noise can cause data errors if the impulses
occur at very specific times during data transmission. If you
suspect noise-related data errors, it may be necessary for you to
reroute the cable or eliminate the source of the impulse.

Temperature

Multi-pair, PVC 24AWG telephone cables have an attenuation

of approximately 8 to 10 dB/100 meters at 20°C.

Page A - 3

TECHNICAL SPECIFICATIONS

The attenuation of PVC insulated cable varies significantly

with temperature. At temperatures greater than 40°C, we

strongly recommend that you use plenum rated cables to
ensure that cable attenuation remains within specification.

A.1.3 Thin-Net Requirements

Cable

Must be 50 ohm RG-58A type coaxial cable.

Length

Must be no longer than 185 meters (607 feet).

Termination

A 50 ohm terminator must be installed at the far end of each
Thin-Net segment.

Connections

A maximum of 30 connections can be used throughout a thin
coaxial segment for host connections. If an excessive number of
barrel connections are used within the cable segment, i.e.,
finished wall plates with BNC feed-throughs, then a reduced
number of host connections may be required.

A.1.4 AUI Cable Requirements

Type

The AUI cable must be Ethernet Version 1, Version 2, or IEEE

802.3, 10BASE-5 type cable that matches the Ethernet device

attached to the AUI port.

Length

The AUI cable must not exceed 50 meters (164 feet) if 24 AWG
AUI cable is used. If 28 AWG AUI cable is used, then the
maximum cable length is 16 meters (52 feet).

Page A - 4

TECHNICAL SPECIFICATIONS

A.1.5 Fiber Optic Requirements

Cable

The fiber optic link segments should consist of either 50/125
micrometer, 62.5/125 micrometer, or 100/140 micrometer fiber
optic cabling.

Attenuation

Cable must be tested with a fiber optic attenuation test set
adjusted for 850 nanometer wavelength. This test verifies that
the signal loss in the cable is acceptable. Attenuation limits for
various cable types are listed below:

-3.0 dB or less for a 50/125 micrometer fiber cable segment

-16.0 dB or less for a 62.5/125 micrometer fiber cable segment

-19.0 dB or less for a 100/140 micrometer fiber cable segment

Fiber Optic Budget

The fiber optic budget and total network propagation delay
should be calculated before fiber runs are incorporated in any
network design.

Fiber optic budget is the combination of optical loss of the fiber
optic cable, in-line splices, and fiber optic connectors.
Propagation delay is the time it takes a packet to travel from
the sending device to the receiving device.

Length

The maximum fiber optic cable length is 2Km (6558 feet), if
system budgets are met. However, IEEE 802.3 FOIRL (Fiber
Optic Inter-Repeater Link) specifications specify a maximum of
1 Km (3279 feet).
