Chapter 1

Overview

Slave Hub Features

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.

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 backplane s. 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.

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.

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.

Hub status LEDs

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.

Overview

Chassis Configuration

Chassis

Model

Options

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.


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.

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.

Standard

Backplane


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.

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.

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.

Master

Module

Backup

Module

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.)

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.

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.



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

7-slot chassis model. You can configure up to six TurboStack hubs in these rackmount models.

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)

Overview

Module

Functions

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.

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.

Further Information

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

Location

Ventilation

Power

Attention

Before installing TurboStack hubs, read the Electrical Safety and

Installation Requirements starting on page i.

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 40 o

C with a department concentrator chassis.

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



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.

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


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 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

Micro Transceivers

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.

Different media connections can be accommodated through the use of an

ATI micro transceiver.

Hub Back Panel Features

As shown in Figure 12, the back panel features of the AT-TS12FS series hubs include:

❑ 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 of each hub

Note

TurboStack hubs without management do not have a firmware cassette port. In a department concentrator configuration, management is provided by the Master module through the chassis backplane.

Hub Status

Indicators

TurboStack hubs have two types of LED displays:

❑ Hub status indicators show the overall condition of the module.

❑ Port indicators show the condition of each port connection. They vary with module type; later chapters of this manual give specifics.

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.

The hub status LEDs shown in Figure 13 appear on both the front and the back panels of every TurboStack hub.

Faceplate

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 Application-

Specific Integrated Circuit (ASIC) developed by ATI for maximum functionality and reliability.

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:








25


Controllers

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.

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

Fiber Optic Ports

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.


ATI micro transceiver. For a list of the ATI micro transceivers available for network connections, see Table 3 on page 19 of this manual.

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.

26



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

Fiber Optic Connectors

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 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.

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.

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:


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.


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.


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



Back Panel Features

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.

The AT-TS12FS/SM, SC, ST hubs have the following back panel layout and features:


❑ 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


The AT-TS24TS hub is based on an Application-Specific Integrated Circuit

32



The AT-TS24TS module repeats 10BASE-T signals according to IEEE

802.3 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-TS24TS or AT-TS24TRS 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-TS24TS hubs through the backplane connector, making a single logical hub.

Controllers

The AT-TS24TS module uses 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-TS24TS Port Configurations

Network Port

The AT-TS24TS hub has a fixed AUI port, located on the back panel. You can use the AUI port to connect the hub to the network in a standalone configuration. In a managed hub, the Master’s front panel 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.



Station Ports

For wiring flexibility, ATI offers 10BASE-T hubs with both individual port connectors and composite connectors for 25-pair cable. The AT-TS24TS has two 50-pin Telco (RJ21) connectors.

50-Pin Telco Receptacle (For Model AT-TS24TS). The 50-pin Telco receptacle on the AT-TS24TS hubs is shown in Figure 23.

When purchasing an octopus cable, make sure that it is wired for 10BASE-T

50-Pin Telco-to-RJ45 Harmonica (For Model AT-TS24TS). ATI offers a harmonica adapter, model AT-ADAPT-2. The harmonica-style adapter for the AT-TS24TS, shown below, allows direct conversion from the 50-pin

Telco-to-RJ45 receptacles. Since 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

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.

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.

LED Displays

Hub Indicators

LED indicators appear on each AT-TS24TS hub, as shown in Figure 25.


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:




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.

The AT-TS24TS has the following back panel layout and features:

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.



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.

LED Displays

Hub Indicators

Port Indicators

The LEDs intentionally do not reflect real-time activity on the AT-TS24TRS 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.

Hub LED indicators for the AT-TS24TRS hub are described below:




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 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.

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.

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.

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.

50-Pin Telco-to-RJ45

Harmonica

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.

53


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

µ s,

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.

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.

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.

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.



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.

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.
