Overview
CentreCOM AT-810SL Multiport Transceiver Fanout
AT-810SL 8 Port
Fanout, Slim-line
Chassis
The CentreCOM Multiport Transceiver Fanouts are part of a family of
multiport transceivers for use with Ethernet Local Area Networks (LANs).
These units can provide network managers with either small standalone
networks or they can act as a concentrator, grouping several devices onto a
single tap on an Ethernet network.
The CentreCOM Multiport Transceiver Fanouts connect up to 8 Data
Terminal Equipment (DTE) workstations, using standard Attachment Unit
Interface (AUI) “Drop” cables in one of 3 switch-selectable configurations.
When “Remote” operation is selected, the unit can attach to an existing
transceiver using an AUI cable up to 50 meters (164 ft.) in length. In “Local”
operation, the network manager has a choice between operation with or
without Signal Quality Error (SQE)/Heartbeat Test. With the flip of a switch,
the network manager can choose to support or not support SQE Test, or
segment the attached nodes from the main network while still allowing local
communication between workstations.
The CentreCOM Multiport Transceiver Fanout interface is compliant with
the IEEE 802.3 specification and compatible with Ethernet Version 1.0 and
2.0.
When used in Remote Mode, the electrical characteristics of the transceiver
are passed transparently through these multiport transceiver fanouts to the
attached nodes as if each unit was attached with its own transceiver. When in
Remote Mode, SQE should be OFF.
Up to 64 stations can be cascaded together through the AT-810SL. This
permits the workstations to be up to 150 meters (492 ft.) from the backbone
cable and up to 200 meters (656 ft.) apart. By cascading the CentreCOM
Multiport Transceiver Fanouts, over a thousand nodes can be attached to a
single backbone cable without requiring repeaters or additional
internetworking devices.

Overview
The AT-810SL has front panel status and diagnostic indicators that provide
“On Line” and “Transmit” status for each port. Figure 1 shows the front
panel. Packet “Receive” and “Collision” indicators are available for the
Transceiver Ports as well as the Station Port. The front panel “System
Power” LED indicates when power is applied to the AT-810SL and the
“Station Power” LED indicates when power is applied to any of the
Transceiver Ports. On the back of the AT-810SL are redundant LEDs
indicating the application of “Station Power” for each Transceiver Port, and
one redundant LED indicating “System Power.”

Installation
Requirements
Attention Before installing AT-810SL Multiport Transceiver Fanouts, read the
!
electrical safety and installation requirements starting on page i.
Before installing the AT-810SL Multiport Transceiver Fanout, ensure that
the following requirements are met:
❑
❑
❑
❑
❑
The network cabling is properly configured.
Power connections are made at the back panel. The AT-810SL
repeater has a universal power supply that will accept either 110 or
220 VAC at 50-60 Hz.
The appropriate IEEE 802.3 AUI standard transceiver cables are
available.
To prevent equipment damage from overheated components,
adequate air flow must be maintained. Before turning on the power,
verify that both the air intake vents on each side of the chassis are free
of obstructions.
For Remote Mode operation, a CentreCOM 100, 200, 150, 250, 270, or
470 Series external transceiver or other IEEE 802.3 Media
Attachment Unit (MAU) may be required. Contact your supplier for
the appropriate model number.
Procedure
IEEE 802.3 10BASE5 (IEC/ISO 8802-3) conventions and standards place
certain limitations on network configurations. Careful planning before
tapping onto the network will help avoid unnecessary problems. The most
important consideration is the transceiver cable length. When operating in
Remote Mode, please ensure that the AT-810SL is within 50 meters (164 ft.)
of the MAU. In either Local or Remote Mode, DTEs must also be located
within 50 meters (164 ft.) of the AT-810SL.

Installation
Once all the cables have been laid and the AT-810SL is placed in the location
of your choice, you are ready to begin the actual connections. (Except for
monitoring the LEDs, there is no benefit in being able to physically see the
AT-810SL during routine operation; the unit may therefore be installed in any
location with adequate ventilation, temperature control and power
connections.)
Power
The CentreCOM AT-810SL Multiport Transceiver Fanout is designed for
desktop or rackmount installation with optional Rack Mount Kits AT-RKMT2 and AT-RKMT-3.
AT-810SL requires a 100-240 VAC power source with a line frequency range
from 50 Hz-60 Hz.
The AT-810SL is equipped with an IEC-320/CEE-22 standard power input
connector on its back panel. One end of the power cord should have a
receptacle to fit this type of connector. The other end should be fitted with the
standard power cord plug for the country in which the unit will be operated.
No power cord is provided for European style AC outlets. Obtain the
appropriate cord from your equipment vendor.

Chapter 3
Operation
Station Port Configuration
The AT-810SL is designed to require a minimum of operator attention during
routine operation. The station port configuration allows access, via an AUI
cable and transceiver, to an Ethernet coaxial cable or fiber optic cable. This
port is only used when the AT-810SL is set in Remote Mode. Once the unit
has been installed and set for your particular configuration, it will be
transparent to the users and to the network.
Two switches are provided on the back panel, allowing selection of Local or
Remote Mode and SQE Test ON or OFF. Local Mode allows operation of the
equipment linked to the AT-810SL as a standalone “mini-network” giving the
option to have the SQE Test ON or OFF, depending on the application. In the
Local Mode the Station Port is disconnected from the Transceiver Ports. In
the Remote Mode (i.e., access to an external transceiver attached to an
Ethernet coaxial or fiber optic cable), the AT-810SL is a “pass-through” unit
with the SQE Test provided by the transceiver connected to the Ethernet
cable. Figure 2 shows the Station Port configuration.
Note
When used in Remote Mode, the SQE Test switch should be OFF.

Operation
LED Status Indicators
The AT-810SL has many LEDs to aid in installation and troubleshooting
should any problems occur. They also serve to verify correct transceiver
operation at a glance. Below is a description of their location, grouping and
functionality. Refer to Figure 3 for location of the System Power and Station
Power.
Front Panel
System Power—When lit, this LED indicates correct AC voltage applied
and internal power supply is operational.
Station Power— When lit, this LED indicates that power (+12 volts) is
applied to Pin-13 of the Station Ports DB15 connector by the MAU backbone
transceiver via the AUI cable.

STATION POWER
Refer to Figure 4 for location of Station Port indicators.
Note
This group of LEDs is associated only with the Station Port and as such are
only active when the AT-810SL is configured for Remote operation via the
two-position Station Port configuration switch.
On Line —When lit, this LED indicates that the Mode Selection switch is in
the Remote position. This is for configuration status only.
Transmit —When lit, this LED indicates a packet is being received into any
of the eight Transceiver Ports and transmitted out through the Station Port.
Receive— When lit, this LED indicates a packet is being received into the
Station Port and is being routed to the eight Transceiver Ports.
Collision—When lit, this LED indicates a Collision or SQE occurrence on
the segment to which the Station Port is connected.

Figure 4: Station Ports
Refer to Figure 5 for the location of the Transceiver Ports.
On Line—When lit, these LEDs indicate that the corresponding
Transceivers Port is connected through an AUI cable to a DTE device, and
that the DTE is powered-up and On Line.
Transmit—When lit, these LEDs indicate that the corresponding
Transceivers Port is receiving a packet and transmitting it to the other seven
Transceiver Ports. If in Remote Mode, this packet will also be sent out
through the Station Port.
Receive—When lit, this LED indicates that each of the Transceiver Ports is
presenting a packet to its associated DTE. Only one LED is required to
represent this function, as all of the Transceiver Ports are effectively parallel
for this function.
Collision—When lit, this LED indicates that a Collision or SQE has
occurred on or between one or more of the Transceiver Ports. This is not a
latched condition, so if this LED is steadily lit, a hard failure or a
configuration problem with one of the DTE’s is occurring, or an inordinate
number of Collisions are occurring, indicating overload and warranting
further attention. Collisions between the Transceiver Ports themselves will
not be propagated through to the Station Port, and thus will not impede
network activity on the Remote Segment.

On Line(s)—Each Transceiver Port has an associated On Line LED. When
lit, these LEDs indicate that the DTE, connected to the related port through
the AUI cable, has power applied to it. These will be lit/unlit regardless of the
AT-810SL’s operational status and are provided so a DTE’s “in use” status can
be ascertained before disconnection of its cable.
System Power—When lit, this LED indicates AC power is correctly
applied and the internal power supply is operational. This indicator is
redundant with the System Power LED on the front panel, it is provided for
ease of viewing from the back in rack mount applications.

Configuration
The CentreCOM Multiport Transceiver Fanout can be used to expand the
number of allowable stations per transceiver in an Ethernet LAN in the
following ways:
❑
❑
❑
❑
Cascading
Additional stations can be attached to an Ethernet coaxial cable
segment which may have limited taps (MAUs) available.
Where numerous stations are in close proximity, the number of
transceivers connected to an Ethernet coaxial cable segment can be
reduced.
The number of stations per Ethernet coaxial cable segment can be
increased, which can reduce the number of segments required.
One AT-810SL can be used to operate as an independent network of
up to eight DTEs (workstations).
The AT-810SL can be configured in a cascaded mode. Utilizing nine multiport
transceivers in this configuration allows a maximum of 64 DTE
(workstations). A cascaded series of multiport transceivers can be operated
as an independent network, or it can be connected to coaxial cable segment
through a CentreCOM 100, 200, 150, 250, 270, or 470 Series transceiver.

IEEE 802.3 Quick Primer
AUI Drop Cables
AUI or Drop cables can be no longer than 50 meters (164 ft.) each.
Attachments may be made only to the cable ends at the 15-pin D-shell
connector. AUI Drop cables may have a maximum 257 ns propagation delay,
as used for computing the worst case propagation delay of a cable system.
AUI cable propagation delay is approximately 5.13 ns/meter. This cable
internally consists of four shielded twisted pair wires with an overall shield
and drain wire; a 15-pin D-shell male connector at one end and a 15-pin
D-shell female connector at the other end. Cable impedance is nominally 78 Ω.
The AUI cable typically connects a transceiver attached to a coaxial segment
to a DTE (workstation).
10BASE-T
10BASE-T UTP media was implemented to reduce Ethernet wiring costs.
UTP wiring is installed in most buildings for telephone systems. Care must
be taken to ensure the UTP wiring used for 10BASE-T is able to carry the
high Ethernet data rates before a 10BASE-T network solution is
implemented. Unlike coaxial Ethernet, 10BASE2 and 10BASE5, 10BASE-T
UTP is point-to-point wiring. Typically, one end is connected to an Ethernet
10BASE-T Network Interface Controller (NIC) or transceiver (MAU) and
the other end is connected to a 10BASE-T hub (repeater). Straight-through
cabling pin-out is used for hub-to-MAU connections. Hub-to-hub and MAUto-MAU connections are allowed using a UTP cable with a cross-over
function crossing TD+ and TD- with RD+ and RD- signals. No other
attachments are allowed along the length of the UTP wire; however, wiring
patch panels and punch-down blocks are allowed for interconnecting
segments. The cable should be Level 3 UTP, 100 Ω impedance, 22 to 26 AWG,
and should not exceed 100 meters (328 ft.) in length from one end to the other.
13
IEEE 802.3 Quick Primer
Thin (10BASE2) Ethernet
When configuring thin coax segments, IEEE 802.3 specifications allow 30 or
fewer MAU attachments per cable segment spaced at no less than 0.5 meters
(1.64 ft.) between each attachment. The thin (10BASE2) cable length can not
exceed 185 meters (606 ft.) per thin (10BASE2) cable segment. The worst
case propagation delay for a 185 meter (606 ft.) thin Ethernet segment is
950.9 ns. The propagation delay for thin (10BASE2) Ethernet cable is 5.14 ns/
meter. Both ends of the segment must be terminated with a 50 Ω termination
with a power rating of 0.5 watts or greater. The segment shield must be
grounded only at one point on the cable.
Thick (10BASE5) Ethernet
When configuring thick coax segments, IEEE 802.3 specifications allow 100
MAU attachments or less, spaced at multiples of 2.5 meters (8.2 ft.) measured
accurately from the cable end (50 Ω terminator included). The thick cable
segment cannot exceed 500 meters (1640 ft.) in length. Worst case end to end
propagation delay of a thick coax segment is 2165 ns. Propagation delay of
thick Ethernet coax is calculated at 4.33 ns/meter. Both ends of the segment
must be terminated with a 50 Ω termination with a power rating of 0.5 watts
or greater. Earth grounding of the segment shield must take place only at one
point on the cable.
Propagation
Propagation delay is the time it takes a signal to travel from the input of a
system component to the output. Propagation delay is usually measured in
nanoseconds. IEEE 802.3 has specific propagation delay maximums for the
Ethernet components. Cable length plays a major role in propagation delay.
i.e, a 50 meters (164 ft.) AUI cable has a maximum propagation delay of 257
ns. The propagation delay of cable is dependent on length and velocity factor
of the cable type.
Round-trip propagation delay through-out the entire cable system, from
farthest ends, may not exceed 51.7 µs, ± 4 µs.
Four Repeater Rule
Up to four repeater units may be connected for a total of five segments
provided that two of the segments are link segments. Link segments have no
MAU attachments. If all segments are coax segments, having MAU
attachments, then a maximum of two repeater units and three segments are
allowed.

Appendix B
Pin Assignments
Notes
Control In Shield (CI-S) is tied internally to the connector shell's Protective
Ground (PG) and is capacitively coupled to ground through a .01 µFD capacitor.
Control In pair [(CI-A) and (CI-B)] are sometimes referred to as “Collision.” This
signal pair carries messages from the MAU to the DTE in a Manchester encoded
format to inform the DTE of the following:
Message
Description
mau_available
Mau is ready to output data to coaxial cable
mau_not_available
MAU is not ready to output data to coaxial cable
signal_quality_error
MAU has detected an error on data input
(collision or self-test of error detection circuitry)
Data Out pair [(DO-A) and (DO-B)], from the DTE to the MAU, carries the actual
data to be transmitted to the network. It is in the form of two messages “output,”
and “output_idle.” The message “output” carries a Manchester encoded logic 1 or
logic 0 bit, and the “output_idle” message informs the MAU that no more data will
be output.
Data In pair [(DI-A) and (DI-B)], from the MAU to the DTE, carries the actual
data received from the network. It is in the form of two messages “input” and
“input_idle.” The message “input” carries an Manchester encoded logic 1 or a logic
0 bit, and the “input_idle” message informs the DTE there is no more input data.
Control Out pair [(CO-A) and (CO-B)], and the Control Out Shield (CO-S) are
optional under the IEEE 802.3 specification and as such are uncommon in the real
world. These signals are not required by any standard products on the market, and
are not implemented in the AT-810SL.
Conductive Shield, no internal connection by AT-810SL, will be grounded
internally by DTE device.
15
Pin Assignments
Voltage Common (Vc) is the ground return path for the Voltage Plus (Vp) supply
voltage (12v-15v 6%) sourced by the DTE to power the MAU. Voltage Plus is
optional under the IEEE 802.3 specification but is typically provided by the
majority of DTE devices, and as such is used to light the “On Line” LED status
indicators on the back panels.

Appendix C
Glossary
10BASE2—Also called thinnet or CheaperNet, 10BASE2 is a 10 MHz,
baseband, 185 meters (606 ft.) maximum coaxial segment. Cable impedance is
50 Ω.
10BASE5—Also called thick Ethernet, 10BASE5 is a 10 MHz, baseband, 500
meters (1639 ft.) maximum coaxial segment. The cable is commonly referred
to as yellow cable. Cable impedance is 50 Ω. Thick Ethernet cable is typically
used as a trunk or backbone path of the network.
10BASE-T—IEEE 802.3 UTP Ethernet. Using low cost Level 3 or better
UTP wiring, 100 meters (328 ft.) of point-to-point link segments are possible.
Uses RJ45 connectors and sometimes 50-pin AMP connectors to a patch
panel.
50-PIN TELCO (RJ21)—This connector is very common in 10BASE-T
wiring. As opposed to the RJ45 connector, the 50-pin Telco connector
concentrates up to 12 UTP connections onto one connection. This
concentration of UTP ports is later broken out for connection to a punchdown block inside a building’s wiring closet. 50-pin Telco connections provide
a very clean, uncluttered interface to the building’s wiring.
ATTACHMENT UNIT INTERFACE (AUI)—This is the cable connection
from a MAU (transceiver) to a DTE (typically a workstation) consisting of a
15 conductor twisted pair cable of 50 meters (164 ft.) maximum length.
BASEBAND COAXIAL SYSTEM—A system whereby information is
directly encoded and impressed on the coaxial transmission medium. At any
point on the medium, only one information signal at a time can be present
without disruption.
BAYONET NUT COUPLE (BNC) CONNECTOR—A 10BASE2 thin
coax connector with push-on BNC locking lug that quickly locks into place
with a half twist.
BIT RATE (BR)—This is the rate of data throughput on the medium in bits
per second. Ethernet specifies 10 million bits per second.
BRANCH CABLE—The AUI cable interconnecting the DTE and MAU
system components also known as a Drop cable.
17
Glossary
BIT TIME—The duration of one bit symbol (1/BR). Ethernet specifies a bit
time of 100 ns.
COAX SEGMENT—A segment of Ethernet cable that contains MAU.
CARRIER SENSE MULTIPLE ACCESS with COLLISION DETECT
(CSMA/CD)—This is the access method employed by IEEE 802.3 LAN
transceivers, by which multiple stations compete for use of the transmission
medium (coax cable) for data packet transmission, and provides for a level of
error detection should that transmission be corrupted or impeded by
contention for the transmission medium.
CARRIER SENSE—In a LAN, an ongoing activity of a data station to
detect whether another station is transmitting.
COAXIAL CABLE—A two conductor (center conductor, shield system),
concentric, constant impedance transmission line used as the trunk medium in
the baseband system.
COAXIAL CABLE SEGMENT—A length of coaxial cable sections and
coaxial connectors, and terminated at each end in its characteristic
impedance.
COLLISION—An unwanted condition that results from concurrent
transmissions on the physical medium.
COLLISION PRESENCE—A signal provided by the PLS to the PMA
sublayer (within the physical layer) to indicate that multiple stations are
contending for access to the transmission medium.
COMPATIBILITY INTERFACE—The MDI coaxial cable interface and
the AUI branch cable interface, the two points at which hardware
compatibility is defined to allow connection of independently designed and
manufactured components to the baseband transmission system.
CROSS-OVER—Wiring is used when connecting a 10BASE-T MAU to
another 10BASE-T MAU or a 10BASE-T hub to another 10BASE-T hub. For
example, one 10BASE-T MAU would have the TD pair on the same pins as
another 10BASE-T MAU. If pins were wired straight, there would be two
transmitters on one pair with no receiver. Therefore, the cross-over cable
crosses the TD pair with the RD pair of UTP cable connecting the TD pins on
one end to the RD pins at the other end.
D-SUB CONNECTOR—The AUI cable uses 15-pin D-sub connectors. “D”
refers to the shape of the connector shell. Also called miniature D, DB15, or
DIX connectors.
DATA COMMUNICATION EQUIPMENT (DCE)—In RS232
specification a unit, such as a modem, for connecting a DTE to other
equipment. A repeater connected to a terminal or workstation for OMEGA
LOCAL management use is wired as a DCE.
DATA TERMINAL EQUIPMENT (DTE)—In RS232 specification a unit
typically at the end of a segment. The DTE could be an Ethernet workstation,
repeater, or bridge.

DEPARTMENT CONCENTRATOR—Hub which provides a large
number of workstation connections. The term, department concentrator,
refers to multiple repeaters housed in an AT-36C8 chassis. See Hub/Repeater,
Repeater.
DIX CONNECTOR—See D-Sub Connector
HARMONICA ADAPTER—This adapter provides a simple way to convert
the 50-pin Telco connection to RJ45 connections.
HEARTBEAT—See SQE
HUB to HUB WIRING—See Hub to MAU Wiring
HUB to MAU WIRING—UTP cables for 10BASE-T hub-to-MAU or
Network Interface Controller (NIC) cards are wired straight-through. An
RJ45 receptacle at the hub would wire pin to pin to the RJ45 receptacle at the
MAU.
HUB/REPEATER—A hub is a central signal distributor. It is used in a
wiring topology consisting of several point-to-point segments originating
from a central point. The term hub is often used interchangeably with the
term repeater. Multiport 10BASE-T, 10BASE2 and fiber optic (10BASE-FL,
FOIRL) repeaters are considered hubs. See Repeater.
HOUSE WIRING—House wiring is the existing wiring inside a building.
This wiring generally originates from one or more wiring closets such as a
telephone room. Some older buildings may have wiring unsuitable for 10
Megabit data rates. In these circumstances, it is recommended that the
wiring is tested with a 10BASE-T signal/wire tester.
IMPEDANCE—An electrical characteristic of a circuit dealing with the
combination of the AC and DC resistance and the appearance of that
resistance to attached circuits.
JABBER LOCK-UP—The MAU’s ability to automatically inhibit the
transmit data from reaching the medium if the transmit data time length
exceeds 150 ms duration. This protects the medium from being overrun with
data packets from a possibly defective device.
JAM—This is a term used to describe the collision reinforcement signal
output by the MAU onto the transmission medium if the transmit data time
length exceeds 150 µs duration. This protects the medium from being overrun
with data packets from a possibly defective device.
JITTER—The fluctuation of the data packet in respect to a standard clock
cycle. Jitter is undesirable and must be minimized.
LINK SEGMENT—The link segment of coaxial cable is a segment which
has no MAU devices but links two LAN devices together such as repeaters.
LINK TEST—In 10BASE-T Ethernet there is a link test function that
validates the UTP link. This consists of a pulse transmitted from point A on
one pair and validated at point B. Point B also transmits a pulse on the second
pair to be validated by point A. These pulses occur during media idle states
(in between packets).

Glossary
MANAGEMENT AGENT—Software that is used to view hub activity and
set hub variables.
MAU—See Medium Attachment Unit
MAU to MAU, HUB to HUB WIRING—10BASE-T MAU to MAU or hub
to hub wiring generally requires a cross-over cable located somewhere along
the UTP cable run. This may commonly occur at the punch-down block or
between the RJ45 wall receptacle and the workstation.
MAU/TRANSCEIVER—An Ethernet transceiver is a MAU. A 10BASE-T
MAU interfaces the UTP media to an AUI port on a workstation, repeater,
bridge, or other Ethernet devices.
MDI—See Medium Dependent Interface
MEDIUM ATTACHMENT UNIT (MAU)—In a LAN, a device used in a
data station to couple the DTE to the transmission medium.
MEDIUM DEPENDENT INTERFACE (MDI)—The mechanical and
electrical interface between the trunk cable medium and the MAU.
N-SERIES—A barrel shaped, threaded connector used on 10BASE5 (thick
Ethernet) coaxial cable.
PATCH PANEL—A 10BASE-T patch panel may be between a punch-down
block and UTP workstation. The patch panel generally has a female RJ45
connector on the front for each workstation and a Telco (RJ21) connector on
the back, which are wired to a punch-down block. This provides a convenient
way for the installer or network manager to connect the hub 10BASE-T ports
into the desired building locations.
PHYSICAL MEDIUM ATTACHMENT (PMA)—The portion of the MAU
that contains the functional circuitry.
PHYSICAL SIGNALING (PLS)—That portion of the physical layer
contained within the DTE that provides the logical and functional coupling
between MAU and data link layers.
POLARITY CORRECTION—Many 10BASE-T UTP ports have a Polarity
Correction function. If the UTP wiring has RD- and RD+ inadvertently
crossed, the polarity correction function will sample the signal and electrically
swap the wires. If the TD- and TD+ wires are crossed, the correction would
occur at the MAU on the other end of the UTP link. This occurs within a
single pair and should not be confused with the cross-over cable.
PROPAGATION DELAY—The time it takes a signal to travel from the
input of a system component to the output. Usually measured in nanoseconds.
IEEE 802.3 has specific propagation delay maximums for computing
propagation budgets when designing a LAN. Cable length plays a major role
in propagation delay. [i.e, a 50 meters (164 ft.) AUI cable has a maximum
allowable propagation delay of 257 ns.] The propagation delay of cable is
dependent on length and velocity factor of the cable type. There are also
propagation delays associated with electronics attached to the system.

PUNCH-DOWN BLOCK—The punch-down block is the wiring panel
where the house wiring from the building’s offices terminates. This is where
many 10BASE-T hubs would be located. Wiring installers use a special
punch-down tool to insert the UTP wire for data and voice applications.
REPEATER—A device used to extend the length, topology, or
interconnectivity of the physical medium beyond that imposed by a single
segment, up to the maximum allowable end-to-end trunk transmission line
length. Repeaters perform the basic actions of restoring signal amplitude,
waveform and timing applied to normal data and collision signals.
RJ45—This connector is a 10BASE-T standard for connecting UTP cabling.
They are inexpensive and easy to install onto UTP cable.
SIGNAL QUALITY ERROR (SQE)—Also referred to as Collision or
Collision Presence. This occurs when two devices attempt to transmit at the
same time which is an illegal condition.
SQE TEST—Commonly referred to as Heartbeat, is a special 802.3 signal
sent by the MAU to the DTE to test the collision detection function. Some
DTE want SQE and others do not. Repeaters do not want SQE Test.
THICK ETHERNET—See 10BASE5
THIN ETHERNET—See 10BASE2
TRUNK CABLE—The trunk coaxial cable system.
UNSHIELDED TWISTED PAIR (UTP)—A cable used in 10BASE-T
wiring that consists of at least two twisted pairs of 22 to 26 AWG wire. The
pairs should have at least 3 twists per foot and have an impedance of 100 Ω.
Level 3 and Level 4 UTP cable generally fits these criteria.
