and Management which uses the optional AT-S9 Firmware Cassette
(Version 2.0).
This manual assumes that you, the user, are familiar with the fundamentals of
Asynchronous Transfer Mode (ATM) technology as well as the operation of
Ethernet switches.
If you are unsure about some of the features included in this document, we
refer you to the reference documentation noted in this preface under the
subheading “Related Documentation.”
As you are probably aware, the standards for electronic networks in general,
and ATM technology in particular, are in transition. They have changed. They
are presently changing. They will certainly change in the immediate future.
In short, while our criteria is valid as of the date of this publication, this arena
of technology is so dynamic that you are cautioned to seek other sources for
the latest standards.

Product Description
Overview
Welcome to Allied Telesyn International!
Allied Telesyn’s AT-4016TR Ethernet Switch With ATM Access, AT-4016F
Ethernet Switch With ATM Access and AT-TS95TR TurboStack Switch With
ATM Access and Management are all Ethernet-to-Ethernet and Ethernetto-ATM switches. All support 10 Mbps of dedicated bandwidth on 16
(AT-4016) or 8 (AT-TS95TR) IEEE 802.3 Ethernet ports. Further, all support
a 155 Mbps Asynchronous Transfer Mode (ATM) port for connectivity to an
ATM switch.
The release of system software Version 2.0 supports Ethernet and ATM
communication over Permanent Virtual Circuits (PVCs).
Your switch also provides an Emulated LAN (ELAN) capability by either
port or MAC address which, in turn, allows you to group all Ethernet ports —
as well as additional switches — as if you are in the same physical LAN.
As stated in the Preface, both switches are almost identical in form and
function. The differences are primarily physical. The following table, repeated
from the Preface, summarizes these differences.

ATI’s Solution
If your LAN is reaching the limit of its bandwidth capacity, then transition
your legacy, shared-media traffic, to a switched 10 Mbps network. Then, by
introducing ATM functionality to connect that same traffic to a server or
backbone (up to theoretically 155 Mbps in this case), bottlenecks will be
mitigated.
This value-effective approach enables you to only “upgrade” devices that
actually need the increased bandwidth (like the server).
Finally, ATI’s ATM switches are the first phase to meet both current and
future needs of your expanding networks. These services will enhance the
business environment for years to come.

Virtual Circuits
There are two types of Virtual Circuits:
1.
Permanent Virtual Circuits (PVCs) and
2.
Switched Virtual Circuits (SVCs).
A connection-oriented technology such as ATM, means that a call or virtual
connection needs to be established between at least two stations before data
can be transferred. This release presently supports Permanent Virtual
Circuits (PVCs). Switched Virtual Channels (SVCs) will be supported in a
later release.
Your switch supports up to 128 PVCs.
4
AT-S7/AT-S9 Operations Manual
Permanent Virtual
Circuits
If connections are established manually through either network management
or remote communications, the channels are called Permanent Virtual
Circuits (PVCs). PVCs are implemented through either a management
program termed Omega or a remote management station. With this release,
each switch must have a PVC connection between itself and every other
switch.
Analogous to a leased or dedicated real circuits found in packet-based
networks, PVCs must be physically configured by a network administrator
from the ATM switch to both establish and maintain ATM connectivity.
LAN Emulation
An Emulated LAN (ELAN) allows you to configure a network through
software instead of rearranging physical cables.
ELANs are created and managed using Omega software management
screens.
Figure 5 shows a typical ATM network topology.

Product Description
Ethernet Switching
There are two popular methods to forward information: store-and-forward
and cut-through. Although your switch employs store-and-forward as the
default, you can also choose cut-through.
Store-and-forward
Store-and-forward means that your switch stores the entire packet and then
forwards it.
Store-and-forward switching, performed at the MAC layer, allows your
switch to temporarily store packets until network resources, typically a
congested port, are available. Frames which are incorrect, an invalid CRC for
example, are discarded. Store-and-forward switching, therefore, ensures data
integrity, thus preventing network error conditions from being generated
throughout the network.
Store-and-forward mode is implemented when packets are converted to cells
on each ATM transmission.
Cut-through
In a cut-through system, the device starts to forward the incoming packet
while the packet is still being received on the inbound link.
Cut-through switching requires software that can both look at the start of the
packet and determine which outbound link is to be used to forward the
packet. Cut-through does not check for errors before forwarding a packet.
Bridging
Your switch operates as a transparent bridge to the Ethernet ports. As such,
it learns the source Media Access Control (MAC) addresses of all incoming
packets and ages out devices which have not been heard for a user or default
specified period of time.
The switch maintains a forwarding table with a maximum storage capacity of
2,048 MAC address. These Ethernet addresses are associated with all of the
devices that have been detected recently.
Your switch checks all incoming packets from each port for their destination
address against a Bridge Address Table. If a packet’s destination address is
not on the same network segment as the originating packet, the switch
forwards the packet to the network segment associated with that destination
address. However, if the packet’s source and destination address are on the
same network segment, known as local traffic, the packet is automatically
discarded (ignored) or filtered.
Bridge Address
Table
6
The switch creates and maintains a dynamic database of addresses which are
stored in a Bridge Address Table. Port information entries in the Bridge
Address Table are, in turn, used as a basis from which to compare and
examine every packet to determine its source address, segment origin and
port information.
AT-S7/AT-S9 Operations Manual
If a packet’s MAC address is not already stored in the Bridge Address Table,
the switch adds the learned address, the associated port number and a timer
value that indicates the age of the dynamic Bridge Address Table entry.
Consequently, the switch knows the address and associated port number the
next time it sees that address. By using the information stored in the Bridge
Address Table, the switch is able to quickly forward each packet to the
correct port.
The switch learns addresses from all packets. When devices are added to the
network, removed from it, or relocated, you do not have to reconfigure your
switch. Your switch automatically learns all addresses.
An address stored in the Bridge Address Table is discarded if there is no
activity from that address after a configured length of time (the default is five
minutes). This aging process ensures that the Bridge Address Table is not
only continually updated but only includes current entries.
Each entry which is automatically entered (a dynamic entry) includes:
❑
An Ethernet MAC address
❑
The port number of the LAN on which the address resides
❑
The age of the entry

Chapter 2
Getting Started
A completely functional ATM network requires the successful integration of
several disparate units:
An AT-4016TR or AT-4016F Ethernet-to-ATM switch, or
An AT-TS95TR Ethernet-to-ATM switch
ATI’s Omega management software
An optional ATM-to-ATM Switch
Getting started involves the following sequence:
1.
Omega management software.
Your switch is controlled by ATI’s Omega management software through
a terminal, a terminal emulator or a Telnet session.
2.
Unique information.
Each switch can be assigned a unique name, location and contact
administrator.
3.
Password.
Password protection is available if network security is required. The
default, of course, does not require a password.
4.
ATM configuration.
ATM connectivity requires ATM address coordination between the
switch’s ATM port and an ATM switch.
9
Getting Started
Getting Started — Omega
Your switch can operate either stand-alone when the backbone port is not
connected to an ATM network — or as an Ethernet switch/ATM Emulated
LAN when the backbone port is connected to an ATM network and
functioning.
To be an operational, stand-alone Ethernet switch, your switch does not
require management (ATI’s Omega, for example) — or any other network
management application. Simply attach your devices to the RJ45 ports, apply
power and you have a working switch.
Main Menu
ATI’s Omega management software is pre-installed and operational when
power is applied to the switch. Configuring Omega depends, however, upon
the requirements of your particular environment.
Omega management enables you to access and configure your ELANs and your
switch.
Omega’s Main menu enables you to access the submenus that are needed to
configure your Ethernet and ATM network.
The following menus are used to either view ATM statistics or configure your
ELAN:
❑
❑
❑
10
Cell statistics - This menu enables you to view ATM cell transmit and
receive statistics as well as Loss of Frame and Sync Events.
Virtual circuit information - This menu enables you to view active VCI
information and statistics. The VCI number, name and type are listed
in this menu. You can view specific VCI statistics in a submenu.
LAN emulation - The Lan emulation menu enables you to access four
ELAN configuration or definition submenus.
AT-S7/AT-S9 Operations Manual
The Main Menu of the AT-4016F switch is shown below. The AT-TS95TR
Main Menu would be identical except for the header.
NOTE
The use of the Port, Frame, and Error statistics submenus are specifically associated
with Ethernet functionality and discussed in Chapter 4, System Administration. Since
they are not used to actually configure an ELAN, they will not be presented here.
From the Main menu you may select any of the following submenus:
❑
Port status - refer to the section “Port Status” on page 45
❑
Frame statistics - refer to the section “Frame Statistics” on page 63
❑
Error statistics - refer to the section “Error Statistics” on page 67

AT-S7/AT-S9 Operations Manual
System Name
From the System Administration submenu, enter the letter S for
System name to access the following submenu. This menu can be used to
enter or change the name of your switch.
You may enter a new name, up to 20 characters in length, or press RETURN to
keep the existing symbolic name. To delete an existing name, enter one or
more space characters (blanks) and then press RETURN.
NOTE
For PVC configurations, it may be helpful to make the system name and ATM
address the same.
13
Getting Started
Password,
Timeout
To assign or change the password or timeout value, return to the System
Administration submenu and enter the letter P for the
Password, timeout submenu:
Password. Password protection restricts unauthorized access to Omega
management. This is a very different type of password protection than
“Download Password” which is found within the IP parameters
submenu which is discussed later. If you choose to use password protection,
the management agent prompts for the password when each new session
begins.
NOTE
The default does not have a password.
You may enter a new password, up to 32 characters in length, or just press
<RETURN> to keep the existing password if there is one. (The screen does not
display your password as you type it; a series of asterisks appears instead.)
To delete your current password, press the spacebar one or more times and
then press <RETURN>.
Timeout. Your switch allows one management session at a time. If a timeout
value is entered, then the Omega session will end when there has been no
activity on the system for the length of time specified.
Timeout may be useful to avoid connection problems due to multiple sessions
(for example, you may start a local session and not exit the system before
attempting a Telnet session later). Note that timeout will also affect the
activity monitor.
14
AT-S7/AT-S9 Operations Manual
The timeout option will automatically end the session if there is no activity
for the length of time specified (in minutes). That is, if a password timeout
value is entered the activity monitor will only run until the timeout time is
reached. The default Ø disables the timeout function.
Remember, if a switch is in session there is no access until the session is
terminated.
A session is terminated in any of three ways:
1.
Timeout
2.
Rebooting
3.
Normal session termination using the Quit option.
Press <RETURN> for the Timeout screen.
15
Getting Started
IP Parameters
Menu
From the Main menu, enter the letter S to reaccess the System
administration submenu:
Enter the letter I for IP parameters to access the following submenu:
16
AT-S7/AT-S9 Operations Manual
A complete discussion of the parameters on this screen is contained in
Chapter 3, Ethernet Administration, and will not, therefore, be presented
here. On the other hand, the following two parameters are required to initiate
a remote network or to download software to switches which have a password
initiated.
Setting an IP Address for Telnet. Telnet requires a configured IP
Address! That is, remote communications with the switch require the use of
the Transmission Control Protocol/Internet Protocol (TCP/IP) suite. Please
refer to Chapter 3 for a discussion of the IP configuration process.
Download Password. Download password is used with TFTP commands
to download software from your switch to other switches in your network.
Download password is not associated with the password used for Omega
management.
If you change the password, ensure that you configure the same download
password for all of the switches that are to be downloaded. That is, the switch
downloading the software and the switches receiving the software must use
the same password. In short, when you use TFTP, the file name for the switch
must be the same as the downloaded password.
The process is as follows: enter the password for the hubs to be downloaded.
For example, if the current download password is ATS7 (all uppercase) then,
upon entering the command H, you will be asked “Please enter a new string,
or <RETURN> to retain the existing one.”
Please refer to Appendix A for a discussion of TFTP and how the download
password is used.

Getting Started
Getting Started — ATM
As stated earlier, this release provides Ethernet to ATM connectivity
through ATM Permanent Virtual Circuits (PVCs). This means that each
switch must have a PVC link between itself and any other switch. Figure 6

every other one. Only units that have devices which need to communicate
need to be connected.

AT-S7/AT-S9 Operations Manual
ATM Parameters Menu
Access the Main menu from Omega management. As previously stated,
Omega’s Main menu enables you to access the submenus that are needed to
configure your Ethernet and ATM network.
Select the System Administration submenu by entering the letter S
from the Main Menu.
19
Getting Started
From the System Administration submenu enter the letters AT for ATM
parameters to access the following submenu:
This submenu enables you to determine the values that regulate your ATM
network. The top part of the display shows the current values.
The following variables can be configured:
Sonet/SDH
Two options are available for the Fiber Optic ATM interface: Synchronous
Optical Network (SONET) STS-3c-type framing (which is more common in
North America) and Synchronous Digital Hierarchy (SDH-1) framing (which
is more common in other countries). The default is SONET. Whichever option
you choose should remain consistent throughout the entire network.
Clocking
The options are either Internal or External. Since the clock signal is normally
supplied by the ATM switch itself, the default is External (loop). Only one
switch in the network should provide clocking.
Cells
20
The ATM specification requires the station to transmit null cells during
periods without traffic. This parameter determines whether these null cells
are either Idle or Unassigned. The default is Unassigned cells and will be
displayed within the Cell statistics submenu.
AT-S7/AT-S9 Operations Manual
ATM Address
ATM addresses are used as a means to identify devices and to communicate
between them.
This software release allows non-standard ATM addresses. This means that
an ATM address may consist of any user-determined arbitrary numerical
designation.
Normally, an ATM address consists of a network prefix, a MAC address and a
selector byte.
[network prefix] [MAC address] [selector byte]
VPI
Like traditional LAN packets, ATM cells contain addressing information.
Rather than addressing cells to specific destination devices, ATM cells are
addressed to Virtual Channels (VCs) and Virtual Paths (VPs).
Ensure that the VIP is set to zero (Ø) in the ATM parameters option within
the System Administration Menu. Ø is the only VPI that is supported at this
time.
Specifically, a Virtual Path Identifier (VPI) is a grouping of a number of
Virtual Channels. It consists of the 8-bit number in an ATM cell header which
identifies the specific virtual path that the cell is traversing in the current
physical circuit.
The switch’s connection management entity uses VCI and VPI to output
tables. Since the connections in the table are established manually through
network management or remote communications, the channels are called
Permanent Virtual Circuits (PVCs).
21
Getting Started
The VPI screen is shown below and is accessed, of course, from the System
Administration submenu.
To use the LAN emulation capabilities of ATM, you establish logical identities
for LANs, paths, channels, and MAC-addressed nodes on your network(s).
Virtual Path Identifier. The Virtual Path Identifier (VPI) for the
AT-TS95TR is set in the LAN Emulation menu (PVC definitions).
Virtual Channel Identifiers. Virtual Channel Identifiers (VCIs) are also
defined in the LAN Emulation menu (PVC definitions). There are 992 VCIs
available between 32 and 1,024 (VCIs between 1 and 31 have been reserved
for ATM management cell purposes). These are used by ATM in the cell
header to direct packets to their correct destinations. (You can also use the
LAN Emulation menu to assign ELAN membership to nodes.)
LAN Emulation Menu
This release implements multiple Emulated LANs. Although each switch can
support up to 64 Emulated LANs, each Emulated LAN requires its own PVC
between units.
Use the LAN Emulation menu to set up Emulated LANs as follows:
1.
Ensure that the VPI is set to zero (Ø) in the ATM parameters option
within the System Administration Menu (Ø is the only VPI that is
supported at this time).
Once the ATM parameters are established, you are ready to configure
Emulated LANs.
22
AT-S7/AT-S9 Operations Manual
Choose LAN Emulation from the Main Menu.
NOTE
You should plan which devices should be included in an ELAN since, as you
may recall, there is no communication between ELANs without ATM routing.
Emulated LAN
Definitions
Submenu
The Emulated LAN definitions option provides you with a list of ELAN names
that you have defined.
23
Getting Started
The Emulated LAN Definition menu provides the following information:
❑
❑
ELAN number - There are 64 possible ELAN numbers per switch.
ELAN Name - This is the ELAN name associated with the ELAN. The ELAN
name field may contain up to 32 characters.
Initially all users are on the default ELAN. In the above illustration, ELANs
2 through 6 have been modified from the default.
Select an ELAN by typing its number as shown on the left of the screen and
press <RETURN>. There are 64 potential ELANs. To see the next set of 16,
press n <RETURN>. To see the previous set, press <RETURN>.
Enter a name, (up to 32 characters in length) or delete the existing name (by
pressing the spacebar) for the selected ELAN.
NOTE
Entering a name for an ELAN activates the ELAN.
The following example shows ELAN Number 1, the default ELAN.
Port to ELAN Configuration Submenu AT-S7
The Port to ELAN Configuration option enables you view the ELAN name
and type of port configuration associated with each port on your switch.
This screen displays each of the sixteen (16) actual AT-4016TR UTP or
AT-4016F Fiber Optic ports as well as the logically defined management port
(Port #17).
24
AT-S7/AT-S9 Operations Manual
By default, all devices on a port are in the same ELAN, but you can override
membership assignments for individual devices on a port. See “MAC Address
to ELAN Configuration Submenu” on page 28.
NOTE
Ensure that the management workstation remains on the same ELAN as the
management client port, Port 17. Otherwise you will lose contact with the
switch via Telnet. If you lose contact, either Telnet in from a station on the
management port’s ELAN, or initiate an Omega local session and reassign the
management station’s port to be on the same ELAN as Port 17.
To make ELAN assignments by port:
Enter po to select the Port to ELAN Configuration submenu.
The Emulated LAN column lists the ELAN that is presently configured to each port.
The Type column contains a user defined keyword to configure the port.
There are normally two keywords used:
❑
❑
MAC - If you select MAC, the MAC address defined in the MAC
address to ELAN configuration menu is used to determine ELAN
membership for a device. This is the default method for assignment of
devices to ELANs. If a device’s MAC address is not explicitly
assigned to an ELAN, it is a member of the port’s ELAN.
FIXED - If you choose Fixed ELAN, all devices on the port join the
port’s designated ELAN regardless of individual device assignments.
The MAC address of the device is ignored.
25
Getting Started
Select a port by typing its number listed on the left of the screen. Port 1 was
selected in this example.
On the ELAN configuration screen for the selected port, you can change the
method the switch uses to assign ELAN membership to network devices.
Choose either M for “MAC address determines ELAN; default is port’s
ELAN” or F for “Fixed ELAN: all devices on this port forced to port’s
ELAN.”
26
AT-S7/AT-S9 Operations Manual
Port to ELAN Configuration Submenu AT-S9
The Port to ELAN Configuration option enables you view the ELAN name and type
of port configuration associated with each port on your switch.
This screen displays each of the eight (8) actual AT-TS95TR UTP ports as

selected in this example.
On the ELAN configuration screen for the selected port, you can change the
method the switch uses to assign ELAN membership to network devices.
Choose either M for “MAC address determines ELAN; default is port’s
ELAN” or F for “Fixed ELAN: all devices on this port forced to port’s
ELAN.”
MAC Address to ELAN Configuration Submenu
Once you have made port-to-ELAN membership assignments, you can assign
up to 128 MAC addresses to membership in an ELAN by selecting MAC
address to ELAN Configuration from the LAN Emulation Menu. If you do
not provide an entry for a given device in the MAC address to ELAN
configuration table, its ELAN membership is the same as the membership of
the port.
NOTE
Designating a port’s Type as Fixed on the Port to ELAN Configuration
menu overrides the individual device assignments in the MAC address to
ELAN Configuration.

PVC Definitions Submenu
The PVC definitions menu shows the current configuration of the
Permanent Virtual Connections (PVCs).
To Configure a PVC
You can add or modify PVC configurations by overwriting the entries in the
table. But first, there are four things you need to consider (and configure) in
order to set up your PVCs.
1.
Determine your ATM Addresses — First, you need to define the ATM
address of the AT-4016 or AT-TS95TR you are configuring. Next, you
must determine the ATM addresses of all devices which will be attached.
To set the address, access the ATM parameters option within the
System Administration submenu. The AT-4016/AT-TS-95TR
uses this address to identify itself when communicating with other
devices. You will need to know this address in order to enable other
devices to access your system. It can be any number.
2.
Define your ELAN — If you wish to use the Default ELAN (ELAN #1)
there is nothing for you to do. If, however, you are using more than one
ELAN, or you do not wish to use the Default ELAN, you must define all
new ELANs by assigning them a name.
31
Getting Started
If you need multiple ELANs, or do not use the default ELAN, you
must define an ELAN name and associate it with a number. To define
your ELAN, access the Emulated LAN Definition option within
the Main Menu. Choose the number and the name you wish to use.
3.
Decide which ports (or MAC addresses) will be assigned to which ELANs.
Access the Port to ELAN Configuration submenu within the
LAN Emulation Menu to set the ELANs you would like to be
enabled on each port. By default all ports belong to ELAN 1 which is
named the “Default ELAN”.
4.
Define your PVCs (up to 128 PVCs can be configured). Access the PVC
Definitions submenu within the LAN Emulation Menu.
VCI — Virtual Circuit Identifier. While you can use Virtual Circuit
Identifiers between 1 and 1,024, VCIs between 1 and 31 have been
reserved for ATM management cell purposes and are not available for
use. Further, the VCI number must be the same on each of the
switches which make up the point-to-point connection.
ATM Address — This is the ATM address of the device this PVC is
going to connect to.
VPI — Virtual Path Identifier. Accessed within the ATM
Parameters submenu within the System Administration
Menu, it must be 0 in this release.
ELAN Number — Pick the correct number of the ELAN you want
this PVC to be a member of, or use the default (Default ELAN).
The above processes can be shown in the following screens:
1.
32
Enter PV for PVC definitions from the LAN Emulation Menu.
AT-S7/AT-S9 Operations Manual
NOTE
It is best to record each configuration option. This will prevent mistakes when
you configure other device.
2.
Select a PVC by typing its number listed on the left of the screen. The
configuration screen for the selected PVC shows the options you must
specify in order to set up a PVC.
3.
Choose v for VCI, a for ATM Address, e for ELAN Number, or d to delete the
PVC definition.

NOTE
While you can use Virtual Circuit Identifiers (VCIs) between 1 and 1,024,
VCIs between 1 and 31 have been reserved for ATM management cell
purposes and are not available for use. Further, the VCI number must be the
same on each of the switches which make up the point-to-point connection.
34
AT-S7/AT-S9 Operations Manual
ATM Address. The ATM address entered here is the one for the remote
system (on the far end of this PVC). It must be unique within this AT-4016.
ELAN ID. If you choose ELAN ID from the PVC Configuration Menu, you can
specify or change which Emulated LAN is associated with the PVC.
35
Getting Started
Status And Statistical Menus
Status and statistical menus are accessible from the Main menu.
NOTE
The use of the Port, Frame, and Error statistics submenus are specifically associated
with Ethernet functionality and discussed in Chapter 3, System Administration. Since
they are not used to actually configure an ELAN, they will not be presented here.
The following additional menus are used to either view ELAN statistics or
configure your ELAN:
❑
❑

Chapter 3
Ethernet Administration
Accessing Omega
To start a session with the management agent, either:
1.
Press the <RETURN> key twice on a PC connected to the RS232 port, or
2.
If your switch has been assigned an IP address, use Telnet to access the
management agent.
A session begins when either of the above events occur. Once in session, the
management agent and the Statistical Database program are “locked” against
other session requests. This prevents unwanted simultaneous access to the
database.
If you have configured a password, the management agent will require it at
the beginning of the session. If you have misplaced the password, you can
unlock the management agent by inserting the optional AT-S7 PCMCIA card
into the PCMCIA port on the AT-4016 or by inserting the optional AT-S9
Firmware Cassette into the appropriate port on the AT-TS95TR.
Selecting Menu
Options
When in session, the management agent offers a series of menus. You may
select from a variety of options to view statistics or control switch activities.
❑
❑
If the options are numbered, type the appropriate number and press
the <RETURN> key
If the options are not numbered, type enough of the option name to
distinguish it from the other options (usually only the first letter).
That is, type the letter(s) which are capitalized; e.g., P (for Port
Status) or F (for Frame statistics).
Except for Quit, choosing a menu usually leads to a submenu which, in turn,
usually leads to yet another submenu.
You can make a choice from the present menu or return to the previous menu
by pressing RETURN or ESC.
41
Ethernet Administration
Some of the submenus cannot fit on a single screen. In this case follow the
instructions on the screen to obtain more information or to go to the next
page.
Password,
Timeout
To assign or change the password or timeout value, return to the System
Administration submenu and enter the letter P for the
Password, timeout submenu:
Password. Password protection restricts unauthorized access to Omega
management. By default, there is no password. If you choose to use password
protection, the management agent prompts for the password when each new
session begins.
You may enter a new password, up to 32 characters in length, or just press
<RETURN> to keep the existing password if there is one. (The screen does not
display your password as you type it; a series of asterisks appears instead.)
To delete your current password, press the spacebar one or more times and
then press <RETURN>.
Timeout. Your switch allows one management session at a time. If a timeout
value is entered, then the Omega session will end when there has been no
activity on the system for the length of time specified.
Timeout may be useful to avoid connection problems due to multiple sessions
(for example, you may start a local session and not exit the system before
attempting a Telnet session later). Note that timeout will also affect the
activity monitor.
42
AT-S7/AT-S9 Operations Manual
Press <RETURN> for the Timeout screen.
The default, “0”, disables the timeout function.
TCP/IP
You must choose a protocol for your network: Is it to be a TCP/IP or a
nonTCP/IP network?
If you have many geographically dispersed subnetworks, each connected to
its own department concentrator, you may want to manage these multiple
switches remotely in a central-site configuration. In this case, TCP/IP
network management may be optimum.
TCP/IP internet addresses consist of user assigned numbers which identify
members of the network. It normally has two fields: network number and
host number. TCP/IP addresses are expressed in the form of a.b.c.d., where
a,b,c and d are each in the 0-254 range. For example, it adheres to the
following notation: 192.136.118.3.
In a nonTCP/IP environment, all switches and devices can be identified by
either any name convention of your choice or by a Media Access Control
(MAC) address (also known as an Ethernet address) which is assigned and
integrated into each switch by the manufacturer. TCP/IP addresses are not
required for local switch management.
43
Ethernet Administration
To Configure a
TCP/IP Address
You can configure the IP Address of the switch by connecting to the serial
port of the switch and bringing up Omega or by using a BootP server. The
local installation of an IP address requires either a DOS terminal or a
Terminal Emulator Program and a serial cable.
Local Installation. Attach your terminal or PC to the RS232 serial port.
Enable Omega using either a DOS terminal or the terminal emulator program
in Windows. Then enter a TCP/IP address for each device.
The path for the appropriate TCP/IP configuration proceeds through Omega’s
Main menu and System administration submenu to the option IP
parameters. Enter the IP address as indicated.
Note that all switches have to be either configured with, or without, an IP
address. They cannot be mixed! A switch with an IP address will not respond
to a Connect remote system query from a switch which does not have an
IP address configured.
BootP
You may also use a BootP server to configure TCP/IP parameters.
At start-up, if an IP address has not been configured, then your switch will
transmit a BootP request packet to the server approximately every three
seconds until a response is received (up to a maximum of three request
attempts).
If a BootP response is not received, then the system will operate with a switch
name or MAC address.
If a BootP response is received, then the IP address, Subnet Mask, and/or
Gateway/Router address will be extracted from the response packet and used
to configure the system until the next power-on/reset.
BootP server file format differs from server to server. The switches expect a
packet containing an IP address, Subnet Mask, and Gateway address.
44
AT-S7/AT-S9 Operations Manual
Port Status
The Main menu of Omega is shown below.
Choose Port Status by entering the letter P. The system will then display the
AT-4016 screen shown below. Note that the AT-TS95TR screen would only
have eight (8) ports.
45
Ethernet Administration
This screen shows the status and configuration of each Ethernet port. At the
top of the screen, you see the system name (if any). Each port is identified by
number and name (if any).
The columns provide the following information:
Port. The Port column shows each port number and its user-assigned name,
if any.
Link. The Link column shows the status of each port’s Link Integrity Test:
either Online or Offline.
Online indicates that IEEE 10BASE-T standard Link Integrity
pulses have been detected on this port.
Offline indicates that Link Integrity pulses have not been detected.
Either the device is not operational (powered down, etc.), or there is a
physical problem with the wiring.
“- -” indicates that Link Integrity Tests are not to be performed on
this port — Link Test has been turned OFF by the management
agent.
Status. There are five possible states: Enabled (Blocking, Listening,
Learning, Forwarding) and Disabled
Enabled indicates a port that is currently forwarding frames — a ready (but
not necessarily currently active) — port. All received frames are discarded
and additional stations are not added to the filtering database.
A port enters the blocking state because it has received information that
another bridge is the designated bridge for the LAN to which the port is
attached.
Blocking indicates a port that is NOT PARTICIPATING in
forwarding frames thusly preventing the creation of multiple topology
paths. Received frames are discarded and frames are not submitted
for transmission. Station locations are not added to the database.
Listening A port in this state is PREPARING TO PARTICIPATE
in frame relay but is temporarily disabled to prevent temporary loops.
Learning is disabled since changes in the active topology may lead to
incorrect information when the active topology becomes stable.
Received frames are discarded and frames are not submitted for
transmission. Station location information is not added to the
database
Learning indicates a port is PREPARING TO PARTICIPATE in
frame relay but it is temporarily disabled in order to prevent
temporary loops. Learning is enabled to allow information to be
acquired prior to frame relay in order to reduce the number of frames
unnecessarily relayed.
Received frames are discarded and frames are not submitted for
transmission. Station location information is added to the database.
Forwarding indicates a port that is PARTICIPATING in frame
relay. It is both forwarding and submitting frames. The learning
process incorporates station location information into the filtering
database.
46
AT-S7/AT-S9 Operations Manual
Received BPDUs will be submitted for transmission. They will also be
processed as required by the STP algorithm.
Disabled indicates a port that is NOT PARTICIPATING in frame relay. Nor
is it participating in the operation of the STP algorithm and protocol.
Received frames are discarded. Submitted frames are not forwarded for
transmission.
Disabled is left when the port is enabled by management action and the
blocking state is entered.
Polarity. The Polarity column shows the state of each UTP port’s receive
pair polarity: either Normal or Reversed.
Normal indicates correct polarity.
Reversed indicates incorrect polarity — software has detected that
your wiring has been installed with reversed polarity. It has also
subsequently corrected it. Operator intervention is not required.
Port Configuration
To change port information, enter a port number from the Port Status menu.
The Port Configuration Menu appears. In this case, port #16 was selected.
The system and port name appear at the top of the screen. Below that is the
port’s status and configuration. And, below that, you see three menu options.
The following configuration options are available:
Enable/Disable. Selecting Enable changes the port’s state to allow it to
transmit or receive data. Selecting Disable turns the port logically off, thus
preventing port traffic.

Ethernet Parameters
The AT-4016 as well as the AT-TS95TR, offer the choice of store-and-forward
(the default) or cut-through switching strategies. In store-and-forward, the
AT-4016 stores the entire packet before it is forwarded.
Error packets which do not have a valid Ethernet length will be discarded
using store-and-forward but not with cut-through. Due to this software
implementation, there is a minimal latency difference between cut-through
and store-and-forward. The preferred method is store-and-forward.
Choose the System Administration submenu again and enter the letter E
for Ethernet parameters to access the following submenu:
NOTE
All changes to Ethernet parameters require a system reset to be activated.
The Ethernet parameters screen shows the current choices for
forwarding and for LED modes of operation. At the bottom you see a list of

52
AT-S7/AT-S9 Operations Manual
Terminal Configuration
Choose the System Administration submenu.
Enter the letter T for Terminal Configuration to access the following
submenu:
Presently configured (or default) options are highlighted with an arrowhead
(“>”).
Changes to the configured terminal characteristics (terminal type and
half/full duplex) take effect immediately. For example, changing from half
duplex to full duplex will cause the management agent to begin echoing your
input immediately. The management agent “remembers” all changes and
retains them in the event of a power failure.
Any changes to serial interface options (data bits, stop bits, parity, data rate)
are “remembered,” but do not take effect until the next management agent
session; i.e., you must select Quit from the Main Menu and then press RETURN
to begin a new session. When you are connected to the management agent
through a virtual circuit connection, these serial interface options have no
effect; they will, however, affect any later sessions with a directly connected
terminal.
ANSI—ANSI “auto configures” the management agent in accordance with the
requirements of an ANSI-standard terminal (essentially the same as a DEC
VT-100 or one of the multitude of terminals emulating the VT-100). ANSI is
also used if you want your screen to be continuously updated.
Generic—The Generic terminal option configures the management agent
for the lowest common denominator terminal. In this configuration, the
management agent makes very few assumptions about the terminal’s
capabilities and is compatible with almost all terminals.
53
Ethernet Administration
Custom Terminal Configuration—Custom terminal definition...
enables the same full-screen display characteristics as the ANSI option, but
with a non-ANSI terminal.
If you select the Custom terminal definition... option, you are led
through three screens to specify the control or escape sequences used by the
terminal. On each screen, you must enter the actual control character
sequence, either by typing control characters individually or by pressing the
terminal’s appropriate function key (if it has one). For example, if the
terminal’s sequence to “home” the cursor is ESC-H, you can either press the
ESC key followed by the H key or simply press the “Home Cursor” function
key on the terminal.
Control sequences may contain common character codes such as “backspace”
or “carriage return” that are also used for input editing. Your input,
therefore, for these screens is handled differently. You must first enter a
delimiter character (choose any character desired). The control sequence is
then entered—normal editing characters are ignored. Finally, to signal the
end of the sequence, and to terminate input, you must enter the same
delimiter character again.
Obviously the control sequence cannot contain the delimiter character itself—
you must choose a delimiter character that is known not to occur within the
terminal’s escape sequence. Also, the flow control characters XON (^Q) and
XOFF (^S) may not appear within any sequence.
If you configure a terminal with an Erase Screen capability, the management
agent will not scroll the screen but will instead erase and paint the screen
from the top. This is generally more pleasant than scrolling.
If the terminal has a Home Cursor capability, the management agent will not
erase or scroll the screen to update an existing display, but will instead
“home” the cursor and then display updated information. This feature avoids
the appearance of screen “flicker.”
The Erase End Of Line (EOL) capability provides an efficient method for the
management agent to erase old information when updating an existing
display. If Erase EOL is not configured, the management agent will use an
appropriate number of space characters to erase old information.
54

Update Software In Another System
There are two prerequisites before you can update software to another
system:
1.
Software cannot be upgraded if either an AT-S7 PCMCIA card or an
AT-S9 Firmware Cassette is installed in the remote device, and
2.
All systems should have the same downloaded password.
Return to the System Administration submenu.
Enter the letter U for Update software in another system. The
following submenu will be displayed.
Next, you are prompted to select a specific switch to download with new
software.
Enter the IP address of the target switch, the target switch name (if
configured), or the target switch’s MAC address. The MAC address can be
obtained from the Diagnostics screen. It may also be found on an external
label above the RS-232 port (or the console port, in some instances).
57
Ethernet Administration
Broadcast Updated Software To All Systems
Choose the System Administration submenu.
Enter the letter B for Broadcast updated software to all systems
to access the following submenu. Note that just the bottom of the scrolled
screen is shown:
A message is broadcast to all other Allied Telesyn switches informing them
that software is to be downloaded if they are not already running the current
software release (the software running on the switch from which you issued
this command is, by definition, the current software release).
Note that you can issue this request at any time without impacting your
switches since only those with ‘old’ software will respond. Also, if you have
many switches, they may not be upgraded with the first update request.
Therefore, to insure that all of your switches are upgraded, the command
should be repeated several times.
After this message is broadcast, the management agent switches to the
activity mode to enable you to monitor downloading.
Note that software cannot be upgraded to switches across routers (different
subnets).
To upgrade switches on a remote subnet:
58
1.
Upgrade one switch on the remote subnet with the AT-S7 PCMCIA card
or the AT-S9 Firmware Cassette.
2.
Connect to the remote upgraded switch and then update software in all
switches. One subnet can be upgraded at a time.

Activity Monitor
This option is used for troubleshooting purposes as well to show if
downloaded software is completed. When directed to a file, technical support
engineers will be able to retrieve this information and, subsequently, use it
towards the determination and resolution of failures.
Open the Main menu and enter the letters AC for the Activity monitor
submenu.
This option displays a variety of messages showing system activity as it
occurs.
59
Ethernet Administration
Diagnostics
Diagnostics enables you to run a limited set of diagnostic tests on currently
selected groups. The results for each test will indicate either Good or Failed.
Choose the System Administration submenu. Enter the letter D for
Diagnostics to access the following submenu:
AT-S7
2.0
The top of the screen shows the user-configured switch name and selected
group name. Below is the group’s product identifier. The group’s unique MAC
address is displayed as a hexadecimal string (this is actually the group’s
Ethernet address), followed by a version identifier for the group’s firmware
and current version of the software.
NOTE
This is the only screen that shows the MAC/Ethernet address and the only
place that you can automatically view the software version level unless, of
course, you have previously entered it manually.
60
AT-S7/AT-S9 Operations Manual
Connect to a Remote System
Select System Administration from the Main Menu. Next, select Connect to
a remote system. The following screen will be shown:
For IP Networks. Enter the IP address of the target switch, switch name,
or MAC address.
This option initiates a Telnet session to another ATI managed switch. This
option is useful when you are managing remote networks.
NOTE
If you are specifying the system by its system name, be sure to enclose the
name in single quotation marks (for example, ‘name’).
When the Telnet connection is established, you will see the remote system’s
Main Menu. Note that a thorough discussion of Telnet and remote
connectivity was discussed in Chapter 2 and you are referred to that
information.
Local switch management does not require TCP/IP addresses. If you are
NOT going to have a TCP/IP network then all switches and devices can be
identified by either a name convention of your choice or by a MAC address
which is assigned and integrated into each switch by the manufacturer).
The switch displays its name at the top of the screen in an Omega session.
This is particularly useful if you have more than one system. You can also use
the name when initiating an Omega session via Telnet from another switch.

❑
EPROM Cassette — through Allied Telesyn’s optional AT-S9
Firmware Cassette
❑
FTP Server
❑
TFTP — using Allied Telesyn’s on-line Omega Manager
TCP/IP family TFTP file transfer procedures
❑
24-hour On-line BBS
❑
Internet
❑
CompuServe
The procedures and telephone numbers for ATI’s BBS, Internet and
CompuServe were presented in the Preface to this document and you are,
therefore, referred to that material.
NOTE
During the downloading process to the AT-4016 or AT-TS95TR, the system
will not function. While the download is taking place, the user interface
becomes inoperable, SNMP requests will not be honored, and packet traffic
to or from the Ethernet ports is suspended. Normal system operation will
resume after the download is completed.
71
Software
PCMCIA
Allied Telesyn offers Omega management software for both the AT-4016
and the AT-TS95TR on, respectively, either a firmware PCMCIA card, the
AT-S7 (see Figure 7), or a Firmware Cassette the AT-S9.
AT-S7
Figure 7: AT-S7 PCMCIA Card
PCMCIA Port. AT-4016 agent software is easy to upgrade through the
PCMCIA port.
The PCMCIA card is a read-only interface used for restoring or updating
software. If a PCMCIA card is installed before a reset or power-up
sequence, the AT-4016TR boots from the PCMCIA card. Otherwise, it
boots from internal Flash RAM.
To update software through the PCMCIA port:
1.
Insert the PCMCIA card into the PCMCIA port. This port is located on
the front panel of the AT-4016 and identified as such.
2.
Reset the unit with either the reset button located on the front panel or
the reset option in Omega management software.
3.
When the LEDs return to normal operation, the update is complete.
During this process the red Alarm LED will display while the LEDs will
cycle through the Network Load LED.
4.
Remove the PCMCIA card.
5.
Reset the unit again. This will allow the system to boot from flash memory.
The new firmware will be copied to the switching system’s onboard
nonvolatile flash memory.

Firmware Cassette Port. AT-TS95TR agent software is easy to upgrade
through the Firmware Cassette port (see Figure 8).
The Firmware Cassette is a read-only interface used for restoring or
updating software. If a Firmware Cassette is installed before a reset or
power-up sequence, the AT-TS95TR boots from the Firmware Cassette.
Otherwise, it boots from internal Flash RAM.
To update software through the Firmware Cassette:
1.
Remove power from the switch.
2.
Insert the Firmware Cassette into the Firmware Cassette port. This port
is located on the rear panel of the AT-TS95TR and identified as such.
3.
Restore power to the switch.
4.
Reset the unit with either the reset button located on the front panel or
the reset option in Omega management software.
5.
When the LEDs return to normal operation, the update is complete.
During this process the red Alarm LED will display while the LEDs will
cycle through the Network Load LED.
6.
Remove power from the switch.
7.
Remove the Firmware Cassette.
8.
Restore power to the switch.
The new firmware will be copied to the switching system’s onboard
nonvolatile flash memory.
73
Software
NOTE
Your system must be reset before any software modifications will be
recognized. This can be accomplished by disrupting power to the switch.
FTP Server
Allied Telesyn has Internet access to an FTP Server in Bothell, WA., for
driver and Readme files on our adapter cards and managed products. The
server can be accessed through your Internet connection as follows (note
— use lower case letters):
Address
gateway.centre.com [lowercase letters]
Login
anonymous [lowercase letters]
Password
your e-mail address [requested by the server when you login]
The first thing you should do once you access the server is to read the
CONTENTS.TXT file. This is a directory of what files are available and
where they are located. All files are compressed and self-extracting; you
can open them by simply typing the file name (most self-extracting files
include multiple drivers, README and support files for specific operating
systems). A file called TECHSUPP.ORT lists the Technical Support
telephone numbers.
For example, the files as shown below are typical:
❑
ATHUB.MIB 154,469 07/14/94 | 3100 HUB MIB; RFC1368 &
MIB II
❑
DwnLds:33 Last DL: 07/14/94 | software.
❑
Omega.ZIP 165,427 08/24/92 | A stand-alone demo of the Omega
management DwnLds: 42 Last DL: 07/14/94 | software.
Once you obtain a new version of software from the Internet Server or
BBS, use TFTP (discussed next) to load the software.
TFTP
74
Software can also be downloaded using the Trivial File Transfer Protocol
(TFTP) and ATI’s image file. A complete discussion of TFTP procedures is
contained in Appendix A and you are referred to that information.
Appendix A
TFTP
Background
Software can be downloaded using the Trivial File Transfer Protocol (TFTP)
and ATI’s image file. ATI’s switches support the use of TFTP in ASCII mode
to both upload configuration parameters to a host and/or download
configuration parameters to a switch.
What this means is straightforward: you can save configuration data from
many switches to a single host. TFTP also allows you to change the
configuration parameters of all switches easily through the use of an editor
and a batch file. Switches can even be reset to the factory default
configuration, if needed. Finally, using defined keywords, any configured
parameter can be chained once the switch has a configured IP address.
To use TFTP, you will need the following:
❑
A TCP/IP stack and a copy of the TFTP utility on your workstation
❑
The download password
❑
The name of the file on the remote host
❑
The IP address of the remote host (the switch)
❑
The local filename (or image filename)
While TFTP utilities vary from vendor to vendor as does the TFTP syntax,
the general form of the command line is as follows:
tftp <direction> <localfile> <hostIP> <ATS7> <mode>
where:
tftp
direction
localfile
hostIP
hostfile
mode
invokes the utility
specifies which way the file is being transferred: get or put
specifies name of file on your workstation
specifies source or destination address
specifies name of file on the remote host (download password)
specifies the file transfer mode: ascii or octet
75
TFTP
TFTP To CIB Configuration Data Requirements
The following information lists the configuration field and the required
character string that precedes the user configuration value that has been
chosen. Each configuration field data text string entry must be separated
from the previous and the following by new line character sequence, i.e.,
carriage return (0x0D hex) or carriage return/linefeed (0x0D 0x0A hex)
character combination. Without this delineation, the configuration of the
fields will not occur. The general format of these configuration field strings is:
FIELD IDENTIFIER = VALUE
Where FIELD IDENTIFIER is specified to the left of the = (or: which is also
allowed) followed by the VALUE.
For example, if you wanted to change the baud rate to 9600:
BAUD = 9600
Text strings must be surrounded by double quotes! If the parameter is multioptional (multiple ports, for example), = must be followed by a designating
number, then a value.
For example if you want port 7 to be designated ‘computer room’ then:
PORT NAME = 7 “COMPUTER ROOM”
BAUD = 9600
If the FIELD is multi-dimensional such as PORT_NAME (which has up to 16
ports), the designating number followed by “=” and then the value.
For example:
PORT NAME [1] = “Port Number 1”
or
ELAN NAME [2] = “Elan Two”
One, or all, configuration fields can be used in a TFTP configuration file for
downloading purposes. When a given configuration file is not to be
downloaded, the default or previously entered configuration data for that field
will remain active.
Text strings require the double quote (“”) character. When a character string
is to be removed, enter a NULL STRING. A NULL STRING is defined as
two consecutive double quotes (“”) which will be interpreted as a string
length of zero.
In the configuration field examples that follow, there are numerous fields that
do not have double quotes around the value that is to be entered. These are
“defined” as constant fields. The allowable constant values are listed for each
field. The use of quotes around the constant value will cause this field setting
to be ignored.
76
AT-S7/AT-S9 Operations Manual
An image file uses a binary format. Configuration data uses an ASCII format.
The switch, however, has the ability to differentiate between the two formats
and, once differentiated, accepts and places this data in the correct place.
NOTE
Not all configuration fields apply to all products. This file includes
configuration data for AT-S7 (4016 with PVC’s), AT-S6 (3690), AT-S9 (TS95)
with PVC’s and AT-S13(4016 with SVC’s). Exceptions are noted.
Get
To obtain a current image for an AT-4016TR/AT-4016F or AT-TS95TR
respectively, enter either:
tftp get image.s7 123.0.0.5 ATS7 octet
tftp get image.s9 123.0.0.5 ATS9 octet
The switch will respond to a TFTP “get” request by transferring an image file
of the software currently executing in that unit to the requesting host. This
enables you to download the software onto another host system.
The switch will respond to a TFTP “get” request by transferring a binary
image of the software currently executing in that unit to the requesting host.
This enables you to upload the software onto the host system. The host
computer should then save the uploaded binary program image into a file
without otherwise modifying it in any way.
When you receive a “get” file from a device that has had its default
configuration values changed, you receive only those parameters, not the
entire configuration.
Put
A TFTP configuration field “put” file involves the use of any, or all,
configuration parameters.
To download the image file for an AT-4016 or AT-TS95TR respectively:
tftp put image.s7 123.0.0.5 ATS7 octet
tftp put image.s9 123.0.0.5 ATS9 octet
Once the file is placed on the switch, downloading procedures are initiated.
The switch responds to a TFTP ‘put’ request by accepting program data from
the sending host. The system will write the new program image into its nonvolatile memory. When the TFTP session is complete, the system will reboot
itself and begin executing the new program.
NOTE
The switch will not accept a TFTP “put” request if a PCMCIA card or
Firmware Cassette is installed.
77
TFTP
When you use TFTP, the file name for the switch must be the same as the
downloaded password. For example, if you had changed the default download
password to ALLIED, and the configuration file on your PC was
NEWCONF, your TFTP command line might look like the following:
TFTP PUT NEWCONF 135.24.35.122 ALLIED ASCII

Glossary
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 AMP connectors to a patch panel and runs at 10 MHz.
ADDRESS RESOLUTION PROTOCOL (ARP)—The procedures and messages in any
communications protocol which resolve local addresses to those of the network. In TCP/IP,
the protocols for translating between IP addresses and physical addresses.
ASYNCHRONOUS TRANSFER MODE (ATM)—A technology for LAN data transport
that packages the data in short fixed length cells for high-speed transport.
ATM FORUM—An international voluntary organization composed of ATM vendors,
manufacturers, service providers, research organizations and users. Purpose is to
“accelerate the use of ATM products and services through the rapid convergence of
interoperability specifications, promotion of industry cooperation and other activities.”
BIT RATE (BR)—The rate of data throughput on the medium in bits per second. Ethernet
specifies 10 million bits per second.

BROADCAST AND UNKNOWN SERVER (BUS)—BUS defines that set of functions
implemented in an ATM network that provide LAN-to-LAN transmission support while a
LAN connection is being established, It also supports LAN broadcast services.
CARRIER SENSE—In a LAN, an ongoing activity of a data station to detect 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.
COLLISION—An unwanted condition that results from concurrent transmissions on the
physical medium.
COLLISION PRESENCE—Provides the ability to detect simultaneous occurrence of
Manchester-encoded data on the DI and DO and to report such an occurrence as a collision
89
Glossary
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.
CYCLIC REDUNDANCY CODE (CRC)—An algorithm used to check for and correct bit
errors in data transmission.
DATA COMMUNICATION EQUIPMENT (DCE)—In RS232 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 RS232 specification a module typically at
the end of a segment. The DTE could be an Ethernet workstation, repeater or bridge.
EMULATED LOCAL AREA NETWORK (ELAN)—See LAN Emulation.
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.
HOT SWAPPING— The process of replacing a module without interrupting the network.
This process occurs by sliding an active module into a fully powered up unit, 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

AC and DC resistance and the appearance of that resistance to attached circuits.
INTERIM LAYER MANAGEMENT INTERFACE (ILMI)—Protocol defined by the
ATM Forum UNI standards for managing the UNI.
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 by the
repeater to all ports. The jam signal consists of 96 bits of alternating 1s and 0s. The purpose
is to extend a collision sufficiently so that all devices cease transmitting.
JITTER—The fluctuation of the data packet in respect to a standard clock cycle. Jitter is
undesirable and must be minimized.
LAN—See Local Area Network
LAN EMULATION—Methodology for mimicking the appearance of a LAN by rendering
the ATM switching fabric invisible to the user; enables user interface software to treat a
virtual LAN as if it were a physical LAN.

AT-S7/AT-S9 Operations Manual
LAN EMULATION CLIENT (LEC)—ATM Forum-defined specifications in support of
LAN-to-LAN connectivity, called LAN Emulation. LEC defines that set of functions
implemented in a LAN DTE to interface with an ATM network in support of LAN
Emulation.
LAN EMULATION SERVER (LES)—LES defines that set of functions implemented in
an ATM network in support of LAN-to-LAN connection establishment.
LAN EMULATION CONFIGURATION SERVER (LECS)—LECS defines that set of
functions implemented in an ATM network that provide LAN DTEs with information
regarding the location of the other LAN Emulation services.
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).
LOCAL AREA NETWORK (LAN)—A type of limited-area broadcast network in which
devices attached to a common transmission medium.
MEDIA ACCESS CONTROL (MAC)—IEEE specifications for the lower half of the data
link layer (layer 2) that defines topology-dependent access control protocols for IEEE LAN
specifications.
MANAGEMENT AGENT—Software that is used to view system activity and set system
variables.
MAU—See Medium Attachment Unit
MAU-TO-MAU, HUB-TO-HUB WIRING—10BASE-T MAU-to-MAU or hub-to-hub
wiring generally requires a crossover 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 the trunk cable medium and the MAU. MDI-X is another version of the interface
that enables like devices to connect using different pin-outs, thereby avoiding conflicts that
occur when receiving and transmitting packets use the same pin-out.
MANAGEMENT INFORMATION BASE (MIB)—A data base of network configuration
and performance information. The formal definition of a MIB includes the names of the
objects it contains and the type of information retained. Management protocols such as
SNMP and CMIP contain procedures for acquiring and exchanging MIB information.
MULTIMODE FIBER—Type of fiber optic cable used for transmitting data over relatively
short distances (maximum 2 km). The fiber contains two materials with different refractive
indices and uses reflection to propagate a relatively low-intensity signal (Class 3 or
equivalent).
NETWORK SERVICES ACCESS POINT (NSAP)—OSI generic standard for a network
address consisting of 20 octets. ATM has specified E.164 for public network addressing and
the NSAP address structure for private network addresses.
91
Glossary
NETWORK SERVICES ACCESS POINT (NSAP)—OSI generic standard for a network
address consisting of 20 octets. ATM has specified E.164 for public network addressing and
the NSAP address structure for private network addresses.
PATCH PANEL—A 10BASE-T patch panel may be used between a punch-down block and
UTP workstation. The patch panel generally has a female RJ45 connector on the front for
each workstation and a Telco (RJ21) connector on the back, which is wired to a punch-down
block. This provides a convenient way for the installer or network manager to connect the
hub 10BASE-T ports into the desired building locations.
PERMANENT VIRTUAL CIRCUIT (PVC)—A virtual circuit (x.25), virtual connection
(Frame Relay) or virtual channel connection (ATM) that has been established by manual or
semi-automated methods in advance of its need. Analogous to a leased/dedicated/
provisioned real circuit.
PHYSICAL MEDIUM ATTACHMENT (PMA)—The portion of the MAU that contains
the functional circuitry.
PHYSICAL SIGNALING (PLS)—That portion of the physical layer contained within the
DTE that provides the logical and functional coupling between MAU and data link layers.
POLARITY CORRECTION—Many 10BASE-T UTP ports have a polarity correction
function. If the UTP wiring has RD- and RD+ inadvertently crossed, the polarity correction
function will sample the signal and electrically swap the wires. If the TD- and TD+ wires are
crossed, the correction would occur at the MAU on the other end of the UTP link. This
occurs within a single pair and should not be confused with the crossover cable.
PROPAGATION DELAY—The time it takes a signal to travel from the input of a system
component to the output. Usually measured in nanoseconds. IEEE 802.3 has specific
propagation delay maxima for computing propagation budgets when designing 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.
SDH—See Synchronous Optical Network.
SIGNAL QUALITY ERROR (SQE) TEST—Signal indicates SQE function is active. The
SQE message is sent by the MAU to the DTE in the presence of a collision.
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.
SINGLE MODE FIBER—Type of fiber optic cable that uses wave propagation within a
homogenous medium to transmit signal over long-range distances (5 to 10 km). Requires
high-intensity laser light source (Class 1 emission).
SONET—See Synchronous Optical Network.
92
AT-S7/AT-S9 Operations Manual
STAND-ALONE—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 connect to the same pins of another connector. For example, pin 1 of one
connector connects to pin 1 of another connector.
STRAIGHT TIP (ST) CONNECTOR—A type of port connection where the pins
connect through a bayonet-style interface.
SUBSCRIBER CHANNEL (SC) CONNECTOR—A type of port connection where
the pins connect through a push-pull mating interface.
SUB MINIATURE ASSEMBLY (SMA) CONNECTOR —A type of port connection
where the pins connect through a threaded attachment interface. Also referred to
as an SM Connector.
SWITCH, ETHERNET—A type of Ethernet hub that filters traffic based on low-level
address. As over against a repeater, a switch does not necessarily broadcast, retime or
retransmit packets, depending on its configuration. A switch cuts down on traffic by placing
packets only on the receiver’s segment when known.
SWITCHED VIRTUAL CIRCUIT (SVC)—A virtual circuit (X.25), virtual connection
(Frame Relay) or virtual channel connection (ATM) that has been established dynamically
in response to a signaling request message.
SWITCHED LAN—Emerging technology that replaces the shared bus backplane of
Ethernet hubs and the shared ring backplane of token Ring hubs with a switching
backplane. Connectivity is provided by switching sender traffic directly to the port of the
addressed destination device. Provides potentially higher throughput, scalable capacity,
and simpler configuration support. Does not require any changes to access wiring or adapter
cards.
SYNCHRONOUS OPTICAL NETWORK (SONET)—A set of physical layer definitions
for data transmission across fiber-based high-speed links. Two options are available for the
Fiber Optic ATM interface: Synchronous Optical Network (SONET) STS-3c-type framing
(which is more common in North America) and Synchronous Digital Hierarchy (SDH-1)
framing (which is more common in other countries). Whichever option you choose should
remain consistent throughout the entire network.
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.
TIME DIVISION MULTIPLEXING (TDM) — This is a technique that combines several
channels onto one high-speed circuit by providing each channel a specific, regularly
recurring time slot sufficsient to carry the full transmission rate of that channel. The
transmixsion rate of the the high-speed circuit must be equal to, or greater than, the
aggregate speed of all of the channels.
TELCO CONNECTOR— A 50-pin receptacle that plugs into the front of the hub, enabling
cables from external devices to connect to the hub.
TRUNK CABLE—Coaxial cable used for distribution of signals over long distances
throughout a cable system.
UNSHIELDED TWISTED PAIR (UTP)—A cable used in 10BASE-T wiring that consists
of at least two twisted pairs of 22 to 26 AWG wire. The pairs should have at least 3 twists
per foot and have an impedance of 100 W. Level 3, Level 4 and Level 5 UTP cables fit these
criteria.
93
Glossary
USER-TO-NETWORK INTERFACE (UNI)—The interface between an end device and a
public or private ATM switch.
VIRTUAL CIRCUIT (VC)—A connection between end users that has defined end points
and route but does not have bandwidth dedicated to it. Bandwidth is allocated on demand
by the network as users have traffic to transmit.
VIRTUAL CHANNEL CONNECTION (VCC)—Virtual channels in two or more
sequential physical circuits can be concatenated to create an end-to-end connection called a
VCC. A VCC is a specific instance of a SVC or PVC. A VCC may traverse one end-to-end
VPC or several sequential VPCs.
VIRTUAL CIRCUIT IDENTIFIER (VCI)—Field in an ATM cell that maps the cell’s
route through the ATM network.
VIRTUAL LAN (VLAN)—A user-configured logical workgroup or collection of Ethernet
addresses, as opposed to a physical LAN defined entirely by wiring.
