Chapter 1
Overview
This manual describes the hardware features and installation
procedures for ATI’s set of TurboStack™ (TS) hubs that are not
manageable as standalone devices. These “Slave” devices include the
AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS models. For
information on the software installation and network management
aspects of TurboStack hubs, refer to the separate TurboStack™ AT-S10
Firmware Module for TurboStack Hubs Operations Manual.
Slave Hub Features
The TurboStack AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS
are multiple port hubs that offer maximum flexibility and redundancy for
department needs. These “Slave” hubs can operate as non-managed
standalone hubs or are manageable in an ATI department concentrator
chassis.
Note
This manual refers to two or more chassis-mounted hubs, at least one of
which is manageable, as a department concentrator. The term hub refers to
either a standalone device (i.e., a single manageable hub) or as part of a
department concentrator configuration.
Each hub is manageable by the Master as a single building block for
TurboStack chassis (department concentrator) configurations with
segmented backplanes. ATI’s TurboStack rackmount department
concentrator chassis can hold up to six hubs in combination with either an
AT-TS90TR or an AT-TS95TR switch module in the bottom slot of the
chassis. Installation of a switch module is optional and requires use of a
segmented backplane instead of the standard backplane used for nonsegmented hubs.
The TurboStack department concentrator chassis can also be configured to
connect up to eight hubs across a standard shared backplane. In this
configuration, a fully populated department concentrator behaves as a
single hub in the network topology. This enables you to build and
reconfigure networks easily, efficiently and at minimum expense.

Overview
Note
For a detailed explanation of ATI’s TurboStack chassis/backplane
offerings, refer to the TurboStack™ Chassis and Backplanes Installation
Manual. This manual describes the physical features and installation
procedures for the chassis models. See your ATI sales representative for
further details.
Data Port
Connectors
TurboStack hubs are based on ATI’s proprietary Application-Specific
Integrated Circuit (ASIC) developed for maximum functionality and
reliability. The AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS
hubs have multiple ports, each with different connectors to provide
flexibility.
Each AT-TS12FS series model has 12 fiber optic (10BASE-FL) ports and is
available with a choice of port connectors as follows:
❑
The ST (Straight Tip) model, which has attachment points with
two pins to connect bayonet-style
❑
The SC (Subscriber Channel) model, which has a square push-pull
mating interface
❑
The SMA (Sub Miniature Assembly) model, which has a threaded
attachment
Note
References in this manual to SMA and SM are interchangeable, both being
acronyms for Sub Miniature Assembly.

TurboStack Series Hubs
The AT-TS24TS and AT-TS24TRS model hubs differ from the AT-TS12FS/
SM, SC, and ST hub models primarily because each AT-TS12FS series
model has 12 paired fiber optic (10BASE-FL) ports on the front panel of
the unit. Also, unlike the AT-TS24TS and AT-TS24TRS model hubs, the
AUI backbone port is mounted on the front panel of AT-TS12FS/ST, SC,
and SM hubs.
Figure 2 shows the AT-TS24TS faceplate with two 50-pin Telco data port
connectors.

The primary physical difference between the AT-TS24TS and AT-TS24TRS
modules is that the AT-TS24TS uses two 50-pin Telco connectors while the
AT-TS24TRS uses 24 RJ45 connectors. However, you can connect an
AT-ADAPT-2 harmonica or an octopus cable to the AT-TS24Ts, enabling
you to use RJ45 connectors.

Hubs with
Management
All three of the TurboStack Slave hubs use an ATI proprietary multiple
port repeater controller to retime and regenerate signals and
communicate with the network management software. The port status for
each of the ports is indicated by an LED display.
For any of these three hubs to be manageable, another hub with
management must perform as a Master in the chassis. Table 2 lists the
TurboStack hubs that can function as Master.

Wiring
Configuration
Rules
Depending on the medium you choose, there are certain wiring practices
you should follow to ensure the reliability of communication throughout
the network. TurboStack hubs comply with IEEE standards for 802.3
Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
Ethernet; you should refer to these standards when implementing your
network. Some important guidelines for ensuring integrity in network
wiring appear in later chapters and the appendices of this manual.

Overview
Chassis Configuration
Commonly called “Slave” hubs because of their dependence on a “Master”
repeater for management, the AT-TS12FS/ST, SC, SM; AT-TS24TRS; and
AT-TS24TS models can function in any of the following four
configurations:
❑
As a standalone repeating device without management: A
standalone Slave hub performs simple regeneration and retiming
tasks in a variety of network configurations. This configuration can
use the hub’s AUI port to connect to a network backbone.
❑
As a hub module in a chassis: Up to 8 Slave modules can be
mounted in a single 8-slot chassis with standard backplane to act
collectively as a single logical hub without a Master.
❑
As a managed module in a department concentrator chassis with
standard backplane and a Master.
❑
As a managed module in a department concentrator chassis with
segmented backplane and a Master.
You can use a single Slave in standalone mode or as part of a department
concentrator housed in a chassis. Each department concentrator chassis
must contain at least one management-capable hub module, or Master, to
enable network management. This module must occupy the uppermost
slot in the chassis because it performs all management reporting
activities.
Chassis
Model
Options
Various chassis models are available for desktop or rackmount
configurations. These include 1-, 2-, 3-, 4-, 7-, and 8-module combinations
for desktop or 19-inch rackmount installations with standard or
segmented backplanes.
You can combine TurboStack and AT-3600 Series Slaves in the same
department concentrator when running AT-S4 firmware. In this hybrid
configuration, however, the management features of the TurboStack hubs
running AT-S10 firmware do not apply. To benefit from the full range of
TurboStack features, you must install only TurboStack hubs in the same
department concentrator.
6
TurboStack Series Hubs
Note
Not all slots have to be populated, and populated slots do not have to be
contiguous. The Master is the top-most module. Any Slave above the
Master will not be managed.
Standard
Backplane
An 8-slot ATI chassis equipped with a standard backplane can hold a
maximum of eight TurboStack hubs connected through the standard
backplane mounted in the inside back wall of the chassis.
Figure 4 shows ATI’s 8-slot chassis with fans and standard backplane.

Overview
Segmented
Backplane
In a 7-slot chassis with a segmented backplane, you can install up to six
TurboStack hubs (i.e., one Master and five manageable modules). The
seventh slot is available for a switch.
As shown in Figure 5, the 7-slot TurboStack department concentrator
chassis incorporates a factory-installed segmented backplane.

Figure 5: Segmented
Backplane (detail)
In a department concentrator configuration with segmented backplane,
the Master unit provides management through the management bus. The
flow of data to/from each port on an installed hub module and the network
backbone is governed by the switch module in the bottom chassis slot. (As
shown in Figure 5, the backplane receptacle for the switch module is offset
from the other backplane receptacles.)
8
Master
Module
TurboStack chassis slots are numbered from 1 through 7, top to bottom.
The Master is defined as the module in the lowest-numbered (physically
topmost) occupied chassis slot. Typically this is slot 1, but it could be any
one of slots 2 through 6 if the slot(s) above are vacant.
Backup
Module
A second management-capable hub may be installed in the slot directly
below the Master (except slot 7) to serve as a Backup management unit.
This special module always occupies the next higher-numbered slot
position below the Master so it can immediately take over the Master’s
functions if necessary.
TurboStack Series Hubs
Slave
Module
Slave modules (AT-TS12FS/ST, SC, SM; AT-TS24TRS; and AT-TS24TS)
may occupy any other higher-numbered slot position in the chassis except
Slot 7 (the bottom slot). They do not need to be adjacent or contiguous. In
other words, Slave units may be separated by empty chassis slots.
TurboStack Department Concentrator
Figure 6 shows a sample TurboStack department concentrator using the

In the seven-slot department concentrator shown in Figure 6, up to 90
ports can be monitored:
❑
One Master containing eight 10BASE2 station ports
❑
Two hubs with management containing a total of twelve (RJ21)
10BASE-T station ports, twenty-four (RJ45) station ports, and two
AUI ports
❑
Two hubs with management containing a total of six (SC) 10BASE-FL
station ports, twelve (ST) 10BASE-FL station ports, and two AUI
ports
❑
One Slave hub containing twenty-four RJ45 station ports for UTP
(The AUI port is not available because of its backplane location)
9
Overview
Note
Depending on the model used, the AUI network port on some Slave
modules cannot be used in a seven-slot department concentrator because
they reside on the back panel of the repeater and are blocked by the
backplane.
Module
Functions
In the department concentrator configuration, the modules perform
different functions:
❑
The top module becomes the Master. It downloads software to and
serves as the reporting unit for other units in the concentrator. It
also controls the management functions.
❑
The module in the slot directly below the Master becomes the
Backup. It assumes management functions if the Master is
removed.
Note
In a department concentrator configuration, both the Master and the
Backup modules must have management capability.
❑
All hub modules between the Master or Backup and the AT-TS90TR
or AT-TS95TR switch in the bottom chassis slot function as Slaves.
They report management information to the Master but do not
perform any control functions.
❑
The bottom slot of the 7-slot chassis may be occupied by either an
AT-TS90TR switch or an AT-TS95TR switch.
Note
The bottom slot of the 7-slot chassis may be left empty with no effect on the
operation of the individual Master, Backup, or Slave modules mounted in
the top six chassis slots. With no switch installed, however, there is no
communication among the units.
Note
Chassis equipped with fans have variable voltage settings—either 120V or
240V. When installing multiple ATI hubs in a chassis with power, setting
the chassis voltage switch too high (at 240V when 120V is required) will
cause overheating of the fans. Setting the voltage too low (at 120V when
240V is required) will reduce the effectiveness of the fans and thus cause
overheating of the installed repeater modules. Check the specific chassis
model to determine the correct voltage setting.
A variety of department concentrator chassis models is available for
TurboStack products. These include chassis with standard or segmented
backplanes. These chassis address a range of needs for different sized
networks and uses. Call your ATI sales representative for details.

Network Management
Network
Management
Planning
Before installing and connecting manageable TurboStack hubs at various
site locations (such as in closets in a single building or in closets on
different floors or in different buildings), you need to decide on the number
of hubs in your network and where each hub is to be located. This
advanced planning will facilitate the assignment of hub names, MAC and/
or IP addresses. It will also maximize the efficiency of network
management once your hubs are fully installed and operational.
If you have a limited number of workgroup terminals and/or devices
collocated on the same floor, for example, you may decide to manage each
hub locally in a standalone configuration. In this scenario, a non-TCP
network may be appropriate.
If you have many geographically dispersed subnetworks, each connected
to its own department concentrator, management of these multiple hubs
remotely in a central-site configuration may require TCP/IP network
management.
Any manageable TurboStack hub can be configured for local or central-site
management. The Omega agent allows local hub management through
the front console serial port connected directly to a terminal or PC.
Note
None of the three TurboStack Slave hubs has network management
capability. However, they can function as part of a department
concentrator configuration, where all the hubs share a common chassis and
backplane and are controlled by the management agent software in a
TurboStack Master module.
Agent Software
ATI provides every manageable TurboStack hub with a pre-installed
software program called Omega. Omega enables network management
either locally through an RS232 terminal port or remotely through a
Telnet session. The Omega agent also supports industry-standard SNMP
Network Management Stations.
Should the Master (or top unit in the chassis) be removed or fail, the
Backup (or second from the top unit) takes over the Master functions
automatically. You can hot swap any module without interrupting hub
management functions.
The TurboStack agent software is easy to upgrade through the firmware
cassette port. When you insert an optional AT-S10 firmware cassette into
this port, at power-up the new firmware providing enhanced security
features is copied to the hub’s onboard non-volatile flash memory.

For further information on AT-S10 capabilities and installation, see
TurboStack™ AT-S10 Firmware Module for TurboStack Hubs Operations
Manual.

Chapter 2
Hardware Installation
Installing the TurboStack hubs without management capability simply
involves plugging the hub into a power source. Additional specific
information on installing the hub in a department concentrator chassis is
in the manual included with the chassis.
Additional specific information about installing TurboStack hubs in a
department concentrator chassis is contained in the TurboStack™ AT-S10
Firmware Module for TurboStack Hubs Operations Manual available
through your ATI sales representative.
Site Preparation
Attention
Before installing TurboStack hubs, read the Electrical Safety and
Installation Requirements starting on page i.
Location
Ventilation
Each of the TurboStack hubs without management can operate as a
standalone product, or installed in a rackmount or desktop chassis.
Multiple hubs can be combined in an ATI chassis.
The site must have adequate ventilation to provide an operating
environment consistent with TurboStack specifications. Chassis models
also are equipped with fans to aid in cooling. For the fans to function
correctly, you must not block the ventilation openings located on the sides
of the chassis.
Note
Maximum ambient temperature is 40o C with a department concentrator
chassis.
Power
Power connections for each hub should be able to provide 50 watts at 120
VAC, for U.S.A. versions; and 100-120/200-240 VAC, 50/60Hz for
international versions. It is not uncommon to use dedicated power circuits
or power conditioners to supply power to the network devices. This aids in
isolating the network equipment from electrical power “noise.”

Hardware Installation
Installing Hubs
This section contains two separate procedures for installing TurboStack
Slave hubs:
❑
Standalone installation
❑
Installation in a managed hub configuration in a concentrator
chassis
Installing a standalone repeater
The following procedure details how to install a TurboStack hub in a
standalone configuration:
1. Plug one end of the power cord into the hub’s power receptacle and the
other end into a power outlet.
2. Check to see that the front panel Power and Master indicators
illuminate. If only the power indicator illuminates, the hub will have
no management. You should also note a soft, humming sound made by
the internal hub fans.
3. Plug your data cables into the hub and the network device. The Link
indicator for each connected port will illuminate.
4. If one or more of the ports are transferring data, the Receive indicator
will illuminate.
5. The hub is now ready to function as an unmanaged repeater unit.
Note
If you power up a Slave module in a standalone configuration, its port
activity LEDs continuously illuminate in sequence until either
management software is downloaded from a Master or a device is
connected to one of the ports on the Slave’s front panel.
Installing a module in a chassis
Attention
Improper installation of the chassis can expose personnel to high voltages,
risking the possibility of injury or death.
Attention
The Master unit must be installed in the uppermost slot of a department
concentrator chassis and must be powered up in order to enable
management of all units installed in the chassis slots below the Master.
14
TurboStack Series Hubs
Attention
Improper installation may expose the repeaters to debris and block vents,
causing damage because of insufficient cooling. When installing multiple ATI
hubs in a chassis with power, setting the chassis voltage switch too high (at
240V when 120V is required) will cause overheating of the fans. Setting the
voltage too low (at 120V when 240V is required) will reduce the effectiveness
of the fans and thus cause overheating of the installed repeater modules.
Check the specific chassis model to determine the correct voltage setting.
Attention
You should always quit the Omega management program at the end of
each session. Otherwise, you might encounter such problems as not being
able to exchange management hubs in a chassis.
Attention
If a fault light and/or the port activity (link) LEDs on the Master illuminate
when you first power-up a hub in a chassis, there may be a problem with
the unit. The recommended sequence of corrective steps is as follows: a)
turn off the power and power-up a second time; b) insert a firmware
cassette in the back panel of the unit; c) initiate a Return Material
Authorization (RMA) to ATI.
Note
If you need to reinstall or update the network management software in a
hub module, refer to the TurboStack™ AT-S10 Firmware Module for
TurboStack Hubs Operations Manual.
The following procedure details how to install a TurboStack Slave module in
a chassis. This procedure is based on the assumption that another module
with management capability is already functioning in the chassis as the
Master unit.
15
Hardware Installation
1. Every ATI hub is shipped with a dust cover on the interrepeater bus
port, located on the back of the module, to prevent static discharge and/
or damage to the connector pins. Before the module is installed in a
multi-module chassis, the dust cover must be removed, as shown in
Figure 7.

5. Align the guide rails on either side of the module with the grooves in
the chassis slot, also shown in Figure 10. Then, slide the module into
the chassis without seating it in the backplane connector.
Note
The segmented backplane is designed with the bottom (slot 7) connector
offset from the other backplane connectors. This is done to accommodate
installation of the AT-TS90TR or AT-TS95TR switch module. If you use a
chassis with a segmented backplane, hubs may be installed only in slots 1
through 6, with slot 7 reserved for a switch module. If you use a chassis
with a standard backplane, hubs may be installed in any of the chassis
slots.
6. Plug in the module’s power cord.
Note
When inserting or removing repeater modules (using the hot swapping
method), you must be sure that the power cord is plugged in. To enable hot
swapping, you must disconnect the module from the backplane before you
unplug the power cord.
7. Check to see that the Power indicator illuminates.
17
Hardware Installation
Attention
Upon initial power-up, the LEDs (including the red fault lights) on all units
connected through a chassis backplane will activate. This is a normal
cycling function and is not any indication of a problem.
Note
When you power-up a Slave module, its port activity LEDs continuously
illuminate in sequence until either management software is downloaded
from a Master or a device is connected to one of the ports on the Slave’s
front panel.
8. Seat the module carefully and firmly in the backplane.
9. Secure the module in the chassis slot by snapping open the plastic
doors on either side of the module faceplate and screwing the module
in place, as shown in Figure 10 above. Then, snap closed the plastic
doors on the faceplate of the module.
10. Connect your data cables to the hub and the network. Check the Link
indicators.
11. If one or more of the ports on the module are transferring data, the
Receive indicator will illuminate.
12. The module is now active in the chassis as a component of a network
concentrator.
For confirmation, you can obtain hub and port status information via
network management from the Master. For details on this topic, refer to
the TurboStack™ AT-S10 Firmware Module for TurboStack Hubs
Operations Manual.
Note
If you have configured your chassis with both AT-3600 and TurboStack
hubs, you will need to refer to the CentreCOM AT-3600 Series and AT-S4
Firmware Cassette User Manual. AT-S10 software will not run on a chassis
configuration that includes both AT-3600 and TurboStack modules. AT-S4,
Release 3.0 or greater, is required when you combine AT-3600 series hubs
with TurboStack hubs. See your ATI sales representative for further
details.
For a detailed explanation of ATI’s TurboStack chassis offerings, refer to
the TurboStack™ Chassis and Backplanes Installation Manual.

TurboStack Series Hubs
TurboStack Port Configurations
AUI Port
TurboStack hubs without management have a fixed AUI port, located on
the front panels of the AT-TS12FS/ST, SC, SM models and on the back
panels of the AT-TS24TRS and AT-TS24TS models. Figure 11 shows the
front panel location of this port on the AT-TS12FS/SC module.
Permanent AUI port
Figure 11: AT-TS12FS/SC AUI
Port
Note
The permanent AUI port is located on the back panels of the AT-TS24TRS
and AT-TS24TS models.
You can use the AUI port to connect the hub to the network in a
standalone configuration. In a managed hub, the Master module’s front
panel AUI port can be used for the network connection. In a non-managed
hub configuration, if you are using a two- or three-slot chassis, one
module’s AUI port can be used for the network connection and the
remaining AUI port(s) may be used for station connections.
Micro Transceivers
Different media connections can be accommodated through the use of an
ATI micro transceiver.

Chapter 3
AT-TS12FS/ST, SC, SM
The AT-TS12FS/ST, SC, SM models are multiport hubs designed to offer
maximum flexibility for both workgroup and department needs.
Specifically, this series of hubs includes three hub module designs, each
with 12 fiber optic (10BASE-FL) ports and an AUI port located on the
front panel.
Note
This manual refers to two or more chassis-mounted hubs, at least one of
which is manageable, as a department concentrator. The term hub refers to
either a standalone hub (i.e., a single manageable hub) or a department
concentrator configuration.
The AT-TS12FS/ST, SC, SM series of hubs are based on an ApplicationSpecific Integrated Circuit (ASIC) developed by ATI for maximum
functionality and reliability.

Since these models do not incorporate management agent software, they
can operate only as part of a non-managed hub or as Slave modules in an
ATI department concentrator chassis.

The AT-TS12FS/ST, SC, SM series of hubs are IEEE802.3 compliant and
Ethernet compatible. When used in conjunction with a TurboStack Master
in a department concentrator chassis, these fiber models can support ATI’s
Omega Agent, Simple Network Management Protocol (SNMP), the second
version of the Management Information Base (MIB-II), and hub MIB.
For the AT-TS12FS/ST, SC, SM series of hubs to be manageable, another
hub must perform as a Master in the chassis.TurboStack hub models that
can function as a Master are listed in Chapter 1 of this manual.
Each manageable TurboStack hub is a single building block for both
standalone and chassis (department concentrator) configurations. ATI
supplies desktop and rackmount department concentrator chassis that
can hold up to eight TurboStack hubs.
Configurations
The AT-TS12FS/ST, SC, SM series of hubs are commonly called a Slaves
because they depend on a Master hub for management. Each of the
AT-TS12FS/ST, SC, SM series of hubs can function in any of the following
four configurations:
❑
As a standalone repeating device without management: A
standalone Slave hub performs simple regeneration and retiming
tasks in a variety of network configurations. This configuration can
use the hub’s AUI port to connect to a network backbone.
❑
As a hub module in a chassis: Up to 8 Slave modules can be
mounted in a single 8-slot chassis with standard backplane to act
collectively as a single logical hub without a Master.
❑
As a managed module in a department concentrator chassis with
standard backplane and a Master.
❑
As a managed module in a department concentrator chassis with
segmented backplane and a Master.
25
AT-TS12FS/ST, SC, SM
There are desktop and rackmount department concentrator chassis
available to hold from two to eight TurboStack hubs. Since the department
concentrator chassis connects hub modules across a backplane, a fully
populated department concentrator behaves as a single hub in the
network topology. This enables you to build and reconfigure networks
easily, efficiently and at minimum expense.
An AT-TS12FS series module repeats 10BASE-FL signals according to
IEEE 802.3 specifications. In an eight-slot department concentrator, up to
97 ports may be monitored (seven Slaves containing 12 10BASE-FL
station ports each and one Master containing 12 10BASE-FL station ports
and one AUI network port).
Note
The AUI network ports on multiple fiber hubs in an eight-slot department
concentrator can be used because they reside on the front panel of the hub
and are, therefore, not blocked by the backplane.
You can expand the number of ports by stacking multiple AT-TS12FS/ST,
SC, SM hubs through the backplane connector, making a single logical
hub.
Controllers
The AT-TS12FS series of hubs use an ATI proprietary multi-port hub
controller to retime and regenerate signals and communicate with the
network management software. The port status for each of the ports is
indicated by an LED display.
AT-TS12FS/ST, SC, SM Port Configurations
Network Port
As shown in Figures 14 through Figure16, the fixed AUI port on the front
panel of each AT-TS12FS series hub may be used to connect a TurboStack
hub without management to the network in a standalone configuration. In
a managed hub, the Master’s AUI port may be used for the network
connection. In a non-managed hub configuration, if you are using a two- or
three-slot chassis, one AUI port is used for the network connection and the
remaining AUI port(s) can be used for station connections.
Different media connections can be accommodated through the use of an
ATI micro transceiver. For a list of the ATI micro transceivers available for
network connections, see Table 3 on page 19 of this manual.
Fiber Optic Ports
26
As also shown in Figures 14 through Figure 16, each of the three
AT-TS12FS series hubs has 12 fiber optic ports. The only differences
among the three models is in the type of connector attachment.
TurboStack Series Hubs
Fiber Optic (10BASE-FL) Wiring Specifications
The IEEE FOIRL standard limits a fiber segment length to 1 km (3,280
ft.). That is, the fiber optic cable that connects two hubs is limited to 1 km
(3,280 ft.). On the other hand, the more recent IEEE 10BASE-FL standard
limits a fiber segment length to 2 km (6,560 ft.). Note, however, that this
only applies to topologies in which one 10BASE-FL node connects to
another 10BASE-FL node. You can intermix 10BASE-FL and FOIRL
nodes, but if the cable connects a 10BASE-FL node at one end and a
FOIRL node at the other, the limitation would revert to the lesser distance
of 1 km (3,280 ft.).
AT-TS12FS/ST, SC, and SM hubs support 62.5/125 micron and 50/125
micron duplex optical fiber cable (duplex refers to fiber optic cable pairs).
Normally, duplex fiber optic cable is labeled TX or TD (transmit) and RX or
RD (receive). This means it has a dedicated transmit cable and a dedicated
receive cable. You must connect the receiving port (RX or RD) on one
device to the transmitting (TX or TD) port on a second device for proper
connectivity.
Connecting a network device to one of the fiber optic ports on the
AT-TS12FS/ST, SC, SM models
1. Attach both connectors at one end of the cable to the TX and RX ports
on the network device.
2. Connect one of the paired connectors at the other end of the cable to the
RX port on the hub.
3. Check for the Link indicator to illuminate. If it does, connect the other
of the pair to TX. If Link indicator stays off, unplug the connector from
RX and use the other of the pair.
Fiber Optic Connectors
Fiber optic hubs use one pair of ST, one pair of SC, or one pair of SM type
connectors per port.
If your existing network uses ST and SMA systems, an ST-SMA, ST-SC, or
an SMA-SC hybrid cable is commercially available. This cable is a
one-meter duplex fiber optic cable with an ST, SC, or SMA connector on
one end and a different one of the three connector types on the other. It
therefore allows easy conversion from one type of connector to the other.
Figure 17 shows the ST (Straight Tip) model whose attachment points
connect bayonet-style.
Figure 17: ST Connector for
Fiber Optic Cabling
27
AT-TS12FS/ST, SC, SM
Attention
The ST connector is keyed. Gently rotate the connector to ensure proper
mating of the ST plug receptacle. Be careful not to force the connector
mating or you might damage the hub’s connector.
Figure 18 shows the square push-pull SC connector. Also shown is the
optional duplexing clip.
Duplexing
Clip

Attention
The SC connector may be installed with an optional duplexing clip, as
shown in Figure 19 above. This clip helps prevent confusion between the
transmit/receive (TX/RX) left-right sequence when an SC connector is
plugged into an SC plug receptacle.
Figure 19 shows the threaded SM connectors.

TurboStack Series Hubs
LED Displays
Hub Indicators
LED indicators appear on each AT-TS12FS/ST, SC, SM hub. The LEDs
intentionally do not reflect real-time activity, because a data packet is too
fast for the human eye to distinguish on the LED indicator; therefore, the
hub artificially stretches the LED ON time for observation. LED
indicators for the AT-TS12FS hub series are described below:
POWER—Green whenever power is applied.
FAULT (OFF under normal operational conditions)—Stays red for a very
short time at power-up; remains solid red if a malfunction is detected
during the diagnostics.
ACTIVITY—The Activity indicator will flash when Ethernet packets are
being transmitted to all hub ports.
Port Indicators
The port indicators on the AT-TS12FS/ST, SC, SM hub front panels
provide visual diagnostic and activity information for network analysis.
Figure 20, for example, shows the port indicators appearing on the front
panel of the AT-TS12FS/ST module.
Port activity LEDs
Figure 20: AT-TS12FS/ST
Port Indicators
Each fiber optic port supports the following indicator functions with one
front panel LED per port:
STEADY GREEN—This indicates that the port has a valid link and is
not partitioned.
FLASHING GREEN—This indicates that the port has a valid link, is not
partitioned, and is receiving data.
STEADY AMBER—This indicates that the port has a valid link and is
partitioned.
29
AT-TS12FS/ST, SC, SM
FLASHING AMBER—This indicates that the port has a valid link and
that there are collisions on the port.
NO LIGHT—This indicates that the port is not functioning.
If you fail to get a Link light at a particular port, one or more of the
following conditions may be occurring:
1. Network device at other end is turned OFF (transmitter is inactive).
2. Cable is damaged or broken, or attenuation is too high (i.e., too little
light is being received because the cable is too long).
3. RX Port has failed.
4. The cabling is incorrect. The RX Port is not connected to TX at the other
end, and you need to reverse the connectors.
Back Panel Features
The AT-TS12FS/SM, SC, ST hubs have the following back panel layout
and features:
❑
Interrepeater bus connector that attaches the TurboStack module
to the backplane bus in a concentrator chassis
❑
Status indicators providing information on the hub as a whole; for
convenience, these LEDs appear on both the front and back panels
Note
The AUI network port is located on the front panel of each of the
AT-TS12FS/SM, SC, ST model hubs.

AT-TS24TS
The AT-TS24TS is a multiport hub designed to offer maximum flexibility
for both workgroup and department needs. Specifically, the AT-TS24TS
uses two 50-pin Telco connectors. In addition, you can connect an
AT-ADAPT-2, or an octopus cable, to the AT-TS24TS, enabling you to use
RJ45 connectors.
Note
This manual refers to two or more chassis-mounted hubs, at least one of
which is manageable, as a department concentrator. The term hub refers to
either a standalone hub (i.e., a single manageable hub) or a department
concentrator configuration.
The AT-TS24TS hub is based on an Application-Specific Integrated Circuit

ports may be monitored (seven Slaves containing 24 10BASE-T station
ports each and one Master containing 12 10BASE-T station ports and one
AUI network port).
Note
The AUI network ports on multiple AT-TS24TS or AT-TS24TRS hubs in an

Appendix B for the pin-out of the Telco connectors for the AT-TS24TS hub
when ordering 10BASE-T harmonica adapters from your wiring vendor.
Alternatively, you may order model AT-ADAPT-2 from your ATI
representative. Figure 24 shows the harmonica-style adapter.

50-Pin Telco-to-Punch-Down Block (For Model AT-TS24TS). Connecting the
AT-TS24TS directly to a punch-down block may be accomplished with a
Telco-connector-to-25-pair-UTP-cable bundle. Refer to Appendix B for the
direct wiring pin-out. Adapter patch panels have a built in punch-down
block for maximum flexibility. Patch panels allow for easy configuration
and reconfiguration of house wiring requirements.
UTP Hub-to-MAU Wiring
For a 10BASE-T link between a hub and a Media Access Unit (MAU)
transceiver or Network Interface Controller (NIC), the cable is wired
straight-through. That is, an RJ45 receptacle at the hub would wire pinto-pin to the RJ45 receptacle at the MAU. The AT-TS24TS follows IEEE’s
10BASE-T hub standard for an embedded cross-over function. Each port
is an MDI-X interface with the receive and transmit pairs crossed
internally.
Note
For information on UTP cabling, refer to the 10BASE-T section in
Appendix A.

TurboStack Series Hubs
LED Displays
Hub Indicators
LED indicators appear on each AT-TS24TS hub, as shown in Figure 25.
Port activity LEDs
Hub status LEDs
Figure 25: AT-TS24TS LEDs
The LEDs on the AT-TS24TS hub intentionally do not reflect real-time
activity, because a data packet is too fast for the human eye to distinguish
on the LED indicator; therefore, the hub artificially stretches the LED
“ON” time for observation. LED indicators for the AT-TS24TS hub are
described below:
POWER—Green whenever power is applied.
FAULT (OFF under normal operational conditions)—Stays red for a very
short time at power-up; remains solid red if a malfunction is detected
during the diagnostics.
ACTIVITY—The Activity indicator will flash when Ethernet packets are
being transmitted to all hub ports.
Port Indicators
The AT-TS24TS port indicators are located on the hubs’ front panel. They
provide visual diagnostic and activity information for network analysis.
Each 10BASE-T port supports the following indicator functions with one
two-color front panel LED per port:
LINK (Solid Green)—This indicates that the particular port has a valid
link and is not partitioned.
RECEIVING (Flashing Green)—When a port’s LED is blinking, the port
is receiving Ethernet packets.
PARTITIONED (Solid Amber)—A solid amber port indicator means the
port is partitioned or segmented from the rest of the ports. This may occur
by a management function or by an error condition on the link.
35
AT-TS24TS
COLLISION (Flashing Amber)—A momentary amber flash occurs when
a collision is detected on the port.
NO LINK (No Light)—If the link test function is not met by the 10BASE-T
device at the opposite end of the UTP segment, this LED will not
illuminate. This may occur if the workstation at the end of the segment is
turned OFF or if the UTP segment is disrupted or damaged.
SELF-TEST (Sequential Flashing Green)—This indicates the hub is
conducting a power-ON self-test. The test continues until one port is
connected (valid link) or the module is connected to the chassis backplane.
Back Panel Features
The AT-TS24TS has the following back panel layout and features:
❑
Interrepeater bus connector that attaches the TurboStack module
to the backplane bus in a concentrator chassis
❑
Status indicators providing information on the hub as a whole; for
convenience, these LEDs appear on both the front and back panels
❑

AT-TS24TRS
The AT-TS24TRS is a multiport hub designed to offer maximum flexibility
for both workgroup and department needs. Specifically, the AT-TS24TRS
has 24 shielded RJ45 connectors for UTP cable. Since the AT-TS24TRS
model does not incorporate management agent software, it can operate
only as part of a non-managed hub or as a Slave module in an ATI
department concentrator chassis.
Note
This manual refers to two or more chassis-mounted hubs, at least one of
which is manageable, as a department concentrator. The term hub refers to
either a standalone hub (i.e., a single manageable hub) or a department
concentrator configuration.
The AT-TS24TRS is based on as Application-Specific Integrated Circuit
(ASIC) ATI developed for maximum functionality and reliability.
Figure 27 shows the faceplate of the AT-TS24TRS model hub.

AT-TS24TRS
As shown in the above figure, the AT-TS24TRS uses 24 RJ45 connectors
for UTP. Since the AT-TS24TRS model does not incorporate management
agent software, it can operate only as part of a non-managed hub or as a
Slave module in an ATI department concentrator chassis.
Features
Table 6 summarizes the features of the AT-TS24TRS hub, including model
number, port count, and media/connector type for each Slave hub.

RJ45 Connectors
The AT-TS24TRS is IEEE 802.3 compliant and Ethernet compatible.
When used in conjunction with an AT-TS00 Master in a department
concentrator chassis, the AT-TS24TRS supports ATI’s Omega Agent,
Simple Network Management Protocol (SNMP), the second version of the
Management Information Base (MIB-II) and Hub MIB.
For the AT-TS24TRS hub to be manageable, another hub must perform as
a Master in the chassis. TurboStack hub models that can function as a
Master are listed in Table 2 on page 5 of this manual.
Each manageable TurboStack hub is a single building block for both
standalone and chassis (department concentrator) configurations. ATI
supplies desktop and rackmount department concentrator chassis that
can hold up to eight TurboStack hubs.
Configurations
The AT-TS24TRS is what is commonly called a Slave hub because it
depends on a Master hub for management, the AT-TS24TRS hub can
function in any of the following four configurations:
❑
As a standalone repeating device without management: A
standalone Slave hub performs simple regeneration and retiming
tasks in a variety of network configurations. This configuration can
use the hub’s AUI port to connect to a network backbone.
❑
As a hub module in a chassis: Up to 8 Slave modules can be
mounted in a single 8-slot chassis with standard backplane to act
collectively as a single logical hub without a Master.
❑
As a managed module in a department concentrator chassis with
standard backplane and a Master.
❑
As a managed module in a department concentrator chassis with
segmented backplane and a Master.
There are desktop and rackmount department concentrator chassis
available to hold from two to eight TurboStack hubs. Since the department
concentrator chassis connects hub modules across a backplane, a fully
populated department concentrator behaves as a single hub in the
network topology. This enables you to build and reconfigure networks
easily, efficiently and at minimum expense.
38
TurboStack Series Hubs
The AT-TS24TRS repeats 10BASE-T signals according to IEEE 802.3 hub
specifications. In an eight-slot department concentrator, up to 181 ports
may be monitored (seven Slaves containing 24 10BASE-T station ports
each and one Master containing 12 10BASE-T station ports and one AUI
network port).
Note
The AUI network ports on multiple AT-TS24TRS or AT-TR24TS hubs in an
eight-slot department concentrator cannot be used because they reside on
the back panel of the hub and are blocked by the backplane.
You can expand the number of ports by stacking multiple AT-TS24TRS
hubs through the backplane connector, making a single logical hub.
Controllers
The AT-TS24TRS hub uses an ATI proprietary multiple port hub
controller to retime and regenerate signals and communicate with the
network management software. The port status for each of the ports is
indicated by an LED display.
AT-TS24TRS Port Configurations
Network Port
The AUI port on the AT-TS24TRS resides on the back panel and is used to
connect the hub to the network only in a standalone configuration. In a
managed hub, the Master’s AUI port may be used for the network
connection. In a non-managed hub configuration, if you are using a two- or
three-slot chassis, one AUI port is used for the network connection and the
remaining AUI port(s) can be used for station connections.
Different media connections can be accommodated through the use of an
ATI micro transceiver. For a list of the ATI micro transceivers available for
network connections, see Table 3 on page 19 of this manual.
Station Ports
The AT-TS24TRS hub is factory built with 24 RJ45 connectors.
UTP Hub-to-MAU Wiring
For a 10BASE-T link between a hub and a Media Access Unit (MAU)
transceiver or Network Interface Controller (NIC), the cable is wired
straight-through. That is, an RJ45 receptacle at the hub would wire pinto-pin to the RJ45 receptacle at the MAU. The AT-TS24TRS follows IEEE’s
10BASE-T hub standard for an embedded crossover function. Each port is
an MDI-X interface with the receive and transmit pairs crossed internally.
Note
For information on UTP cabling, refer to the 10BASE-T section in
Appendix A.

Port Indicators
The AT-TS24TRS port indicators on the hubs’ front panels provide visual
diagnostic and activity information for network analysis. Each 10BASE-T
port supports the following indicator functions with one two-color front
panel LED per port:
LINK (Solid Green)—This indicates that the particular port has a valid

NO LINK (No Light)—If the link test function is not met by the 10BASE-T
device at the opposite end of the UTP segment, this LED will not
illuminate. This may occur if the workstation at the end of the segment is
turned OFF or if the UTP segment is disrupted or damaged.
SELF-TEST (Sequential Flashing Green)—This indicates the hub is
conducting a power-ON self-test. The test continues until one port is
connected (valid link) or the module is connected to the chassis backplane.

Troubleshooting
This section provides a checklist for resolving problems associated with
your hub and cabling. The first rule of troubleshooting is to isolate the
problem. As you experiment, only vary one factor at a time. Substitute
known good equipment to see if the problem persists or is eliminated.
As a preliminary check, perform the following steps
1. Do not overlook the obvious—check diagnostic LEDs and make
sure the cables and connectors are securely attached.
2. If there is no power indication, check to be sure the power plug is
properly seated at the repeater and at the AC receptacle.
3. (UTP models only) If the UTP Link indicator does not illuminate,
make sure the cabling is intact and connected to a functioning port on
the network. Check the cable configuration to make sure the
connectors are wired correctly and a cross-over cable is not necessary
(see Appendix A for details).
4. Use only UTP cable designed for use in 10BASE-T applications.
10BASE-T wiring lengths should not exceed 100 meters (328 ft.). The
wiring should be routed away from devices known to emit
electromagnetic interference, such as fluorescent lights, photocopiers,
power transformers and relay equipment.
5. If the Link indicator illuminates on a 10BASE-T segment, but
data transfer is slow, collision-prone or non-existent, verify that
your UTP cable is of Level 3, 4 or 5. Level 1 and 2 voice-quality cable
will not work properly. If the cable is more or less round in section, you
probably have data-grade cable. If, however, the cable appears flat
(such as “Silver Satin” telephone-type cable), you probably have voicegrade cable which may cause transmission problems. If it looks like
telephone cable, double check it. Also, if the wire pairing is incorrect,
you may get a Link indication but have high data error rates.
6. If the Link indicator does not illuminate on a fiber optic
segment, check to be sure the connectors are properly seated and that
Receive connects to Transmit on the network device and vice versa.
Check to be sure the cable conforms to specification and that the
distance has not been exceeded.
43
Troubleshooting
7. If too many collisions are present on an AUI connection, check
to ensure that the external Ethernet transceiver connected to the AUI
port has the SQE Test (Heartbeat) function disabled. Excessive
network loading can also cause excessive collisions.
8. If a fault occurs (fault light stays ON), disengage the repeater module
from the backplane, unplug and replug the power cord, and reseat the
module.
44
Appendix A
UTP Wiring Specifications
10BASE-T requires UTP wiring capable of supporting 10 Megabit data
rates. Use Level 3 or better UTP wiring throughout the 10BASE-T wiring
system. The wire should be 22 to 26 AWG, 100 Ω impedance with 3 to 8
twists per foot. Typically, if a cable is flat, the pairs are untwisted and will
cause problems. A cable more or less round in section is likely to be
twisted.
The specifications of 6 common modular cables and their applicability to
10BASE-T network use are shown in Table 7. The maximum length for
10BASE-T UTP segments is 100 meters (328 ft.).

50-Pin Telco-to-RJ45
Octopus Cables
The 10BASE-T ‘octopus’ cable breaks out the AT-TS12T or AT-TS24T Hub
50-pin Telco connector to individual RJ45 connectors. This is an ideal
method for connecting into a patch panel in the wiring closet. Patch panels
allow for easy configuration and reconfiguration of house wiring
requirements.
When you purchase an octopus cable, ensure that it is wired for 10BASE-T
and that Level 3 UTP is used. This will help maintain 10 megabit data
integrity throughout the wiring system. “Silver Satin” flat cable is out of
specification and should not be used.

Allied Telesyn offers a harmonica adapter, Model AT-ADAPT-2. The
harmonica-style adapter shown in Figure 34 allows direct conversion from
the 50-pin Telco connector to RJ45 receptacles. There are many different
standards for the pin-out of the harmonica adapter. Make sure that the
pin-out of the adapter you use complies with the 10BASE-T wiring
specification. Refer to Table 8 on page 50 for the pin-out of the Telco
connector for the AT-TS12T if you order a 10BASE-T harmonica adapter
from a wiring vendor other than ATI.
Appendix C
IEEE 802.3 Quick Primer
10BASE-T
10BASE-T UTP media were implemented to reduce Ethernet wiring costs.
UTP wiring is installed in most buildings for telephone systems. Make
sure the UTP wiring used for 10BASE-T is able to carry the high Ethernet
data rates before you implement a 10BASE-T network solution.
Unlike coaxial Ethernet, 10BASE2 and 10BASE5, 10BASE-T UTP is
point-to-point wiring. Typically, one end is connected to an Ethernet
10BASE-T 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 MAU-to-MAU connections are
allowed when you use a UTP cable with a crossover 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 at least 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.
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 (such
as fiber) have no MAU attachments. If all segments are coax segments
with MAU attachments, a maximum of two repeater units and three
segments is allowed.
10BASE-FL/FOIRL Ethernet
The IEEE 802.3 10BASE-FL standard supports up to 2,000 meters (6,560
ft.) of multimode duplex fiber optic cable in a point-to-point link which
directly attaches two devices. FL is compatible with FOIRL, but FOIRL
only supports connections of 1,000 meters (3,280 ft.). Duplex refers to
support for fiber optic cable pairs, enabling a two-cable fiber optic
connection with transmit mode dedicated to one cable and receive mode to
the other. The wide dynamic range of a fiber optic interface facilitates
installation. When connecting fiber optic cable, you must connect the
receiving pin (RD) to the transmitting pin (TD) and vice versa.

IEEE 802.3 Quick Primer
10BASE2 (Thin) Ethernet
When configuring thin coax segments, IEEE 802.3 specifications allow up
to 30 MAU attachments per cable segment, spaced at no less than 0.5
meters (1.64 ft.). The 10BASE2 cable length cannot exceed 185 meters
(606 ft.) per 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 earth grounded at only one
point on the cable.
10BASE5 (Thick) Ethernet
When configuring 10BASE5 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 10BASE5 cable segment cannot exceed 500 meters (1640 ft.) in
length. Worst-case end-to-end propagation delay of a 10BASE5 coax
segment is 2165 ns. Propagation delay of 10BASE5 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 at only one point on the
cable.
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.
Internally, this cable consists of four shielded twisted-pair wires with an
overall shield and drain wire; there is 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 with a DTE (workstation).
Propagation
Propagation delay is the time it takes a signal to travel from the input of a
system component to the output; it is usually measured in nanoseconds.
IEEE 802.3 has specific propagation delay maximums for the Ethernet
components. Cable length plays a major role; i.e., a 50 meters (164 ft.) AUI
cable has a maximum propagation delay of 257 ns. The propagation delay
of cable depends on the length and velocity factor of the cable type.
Round-trip propagation delay throughout the entire cable system, from
farthest ends, may not exceed 51.7 µs, ± 4 µs.

Appendix D
Glossary
10BASE2—Also called thin Ethernet, thinnet or CheaperNet, a 10 MHz
baseband specification. Cable impedance is 50 Ω and maximum coaxial
segment length is 185 meters (607 ft.).
10BASE5—Also called thick Ethernet, a 10 MHz baseband specification. Cable
impedance is 50 Ω and maximum coaxial segment is 500 meters (1,640 ft.). The
cable is commonly referred to as yellow cable. Thick Ethernet cable is typically
used as a trunk or backbone path for the network.
10BASE-FL—IEEE 802.3 Fiber Optic Ethernet. A fiber optic standard that
allows up to 2,000 meters (6,560 ft.) of multimode duplex fiber optic cable in a
point-to-point link.
10BASE-T—IEEE 802.3 UTP Ethernet. Low-cost Level 3 or better UTP wiring
affords 100 meters (328 ft.) of point-to-point link segments. UTP uses RJ45
connectors and sometimes 50-pin Telco connectors to a patch panel and runs at
10 MHz.
50-PIN TELCO (RJ21)—This connector is very common in 10BASE-T wiring.
Unlike the RJ45 connector, the 50-pin Telco connector concentrates up to 12
UTP connections onto one connection. This concentration of UTP ports is then
broken out for connection to a punch-down block inside a building’s wiring
closet. 50-pin Telco connections provide a very clean, uncluttered interface to
the building’s wiring.
AT-ADAPT-2— A harmonica-style adapter that allows direct conversion from
a 50-pin Telco connector to RJ45 receptacles.
ATTACHMENT UNIT INTERFACE (AUI)—Connection between a MAU
(transceiver) and a DTE (typically a workstation). Includes a 15-pin D-sub
connector and sometimes a 15-conductor twisted pair cable. Maximum length
is 50 meters (164 ft.).
BACKUP MODULE— A repeater that behaves as the management module
when the Master fails in a department concentrator.
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.
55
Glossary
BAYONET NUT COUPLE (BNC) CONNECTOR—A 10BASE2 thin coax
connector with push-on BNC locking lug. This lug quickly locks into place with
a half twist.
BIT RATE (BR)—The rate of data throughput on the medium in bits per
second. Ethernet specifies 10 million bits per second.
BIT TIME—The duration of one bit symbol (1/BR). Ethernet specifies a bit
time of 100 ns.
CARRIER SENSE—In a LAN, an ongoing activity of a data station that
detects whether another station is transmitting.
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. It provides for a level of
error detection should that transmission be corrupted or impeded by
contention for the transmission medium.
COAX SEGMENT—A segment of Ethernet cable that contains MAUs.
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, terminated at each end in its characteristic impedance.
COLLISION—An unwanted condition that results from concurrent
transmissions on the physical 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 with the baseband transmission system.
CROSSOVER—Wiring 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 has 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
and no receiver. As a solution, the crossover cable crosses the TD pair with the
RD pair, to connect 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 RS-232 specification,
a module, such as a modem, for connecting a DTE to other equipment. A
repeater connected to a terminal or workstation for Omega management use is
wired as a DCE.
DATA TERMINAL EQUIPMENT (DTE)—In RS-232 specification, a module
typically at the end of a segment (i.e., uninterrupted length of Ethernet cable).
The DTE could be an Ethernet workstation, repeater or bridge.
56
TurboStack Series Hubs
DEPARTMENT CONCENTRATOR—Hub that provides a large number of
workstation connections. The term department concentrator refers to multiple
repeaters housed in an AT-CTS 7-slot or AT-C36C 8-slot chassis. See Hub/
Repeater, Repeater.
DIX CONNECTOR—See D-Sub Connector
FOIRL — A fiber optic standard that allows up to 1,000 meters (3,280 ft.) of
multimode duplex fiber optic cable in a point-to-point link.
HARMONICA ADAPTER—This adapter provides a simple way to convert
the 50-pin Telco connection to RJ45 connections. See AT-Adapt-2.
HEARTBEAT—See SQE
HOT SWAPPING— The process of replacing a hub module without bringing
down the network. This process occurs when you slide an active module into a
fully powered-up concentrator, replacing a failed module.
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
be tested with a 10BASE-T signal/wire tester.
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.
HUB-to-HUB WIRING—See MAU-to-MAU Wiring
HUB-to-MAU WIRING—UTP cables for 10BASE-T hub-to-MAU or NIC
cards are wired straight-through. An RJ45 receptacle at the hub would wire
pin-to-pin to the RJ45 receptacle at the MAU.
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 exceeds a
specified duration. This duration is in the range of 20 ms to 150 ms. Jabber
lock-up 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
sent by the repeater to all ports. The jam signal consists of 96 bits of alternating
1s and 0s. Its purpose is to extend a collision sufficiently so that all devices
cease transmitting.
JITTER—The shift of the data bit 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 that has no
MAU devices, but links together two LAN devices such as repeaters.
57
Glossary
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 that is 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).
MANAGED MODULE— An intelligent repeater in a department
concentrator chassis that makes management data available to the Master.
MANAGEMENT AGENT—Software that is used to view hub activity and set
hub variables.
MASTER—A repeater in the topmost position in a department concentrator
chassis that contains and downloads the management agent software to
Backup and Slave modules. The Master contains the only active image of the
management agent and controls the management functions of the Backup and
Slaves.
MAU—See Medium Attachment Unit
MAU-to-MAU, HUB-to-HUB WIRING—10BASE-T MAU-to-MAU or hub-tohub 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 device.
MDI/MDI-X—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 a hub and a transceiver (MAU). MDI-X is another
version of the interface that enables hubs to connect using different pin-outs,
thereby avoiding conflicts that occur when receiving and transmitting packets
use the same pin-out.
MODULE—A single repeater when it is mounted with other repeaters in a
department concentrator chassis.
N-SERIES—A barrel-shaped, threaded connector used on 10BASE5 (thick
Ethernet) coaxial cable.
PATCH PANEL—A 10BASE-T patch panel may be used between a punchdown block and a 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; through the RJ21 connector, the patch panel is wired to a punchdown block. This provides a convenient way for the installer or network
manager to connect the hub 10BASE-T ports into the desired building
locations.
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.
58
TurboStack Series Hubs
PROPAGATION DELAY—The time required for a signal to travel from the
input of a system component to the output. Usually measured in nanoseconds.
IEEE 802.3 stipulates specific propagation delay maximums for computing
propagation budgets when you design a LAN. Cable length plays a major role
in propagation delay; for example, a 50-meter (164-foot) AUI cable has a
maximum allowable propagation delay of 257 ns. The propagation delay of
cable depends on the 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. It
is 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. All ATI transceivers test for SQE.
SIMPLE NETWORK MANAGEMENT PROTOCOL (SNMP)— SNMP is a
TCP/IP protocol that generally uses the User Datagram Protocol (UDP) to
exchange messages between a management information base and a
management client residing on a network. Since SNMP does not rely on the
underlying communication protocols, it can be made available over other
protocols, such as XNS or DECnet.
SLAVE— A repeater that behaves as a “dumb” module managed by a Master
in a department concentrator chassis. Slaves operating standalone perform
only simple regeneration and retiming tasks associated with repeating and are
not manageable.
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 the SQE Test.
STANDALONE—Repeater operating as a hub on its own; i.e., not a module
among other modules in a department concentrator chassis.
STRAIGHT-THROUGH—A type of wiring connection where the pins of one
connector interface with the same pins of another connector. For example, pin
1 of one connector connects to pin 1 of another connector.
SUBSCRIBER CHANNEL (SC) CONNECTOR—A type of port connection
where the pins connect through a square push-pull mating interface.
SUB MINATURE ASSEMBLY (SMA) CONNECTOR—A type of port
connection where the pins connect through a threaded attachment interface.
(Also referred to as an SM Connector.)
STRAIGHT TIP (ST) CONNECTOR—A type of port connection where the
pins connect through a bayonet-style interface.
59
Glossary
TCP/IP PROTOCOLS—A set of protocols for intercomputer communication,
including network level (Internet Protocol), transport level (Transmission
Control Protocol or TCP) and application level protocols (for example, Telnet
terminal emulation). TCP/IP has been used for many years in two country-wide
networks, the ARPANET and MILNET. Recently, TCP/IP has become very
popular with users of a variety of multi-user computer systems and
engineering workstations. Most UNIX computers use TCP/IP over Ethernet as
the main intercomputer networking technology. TCP/IP is also popular among
PC users, particularly as a means of communication with large multi-user
computers.
TELCO CONNECTOR— A 50-pin receptacle that plugs into the front of the
hub, enabling cables from external devices to connect to the hub.
THICK ETHERNET—See 10BASE5
THIN ETHERNET—See 10BASE2
TRUNK CABLE—The coaxial cable used to distribute signals over long
distances throughout a cable system.
UNMANAGED MODULE— A repeater that behaves as a “dumb” repeater in
a department concentrator chassis (i.e., without a Master). It performs simple
repeating tasks like packet retiming and regeneration, but is not managed.
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,
Level 4 and Level 5 UTP cables fit these criteria.
