Administration features
The DSL Terminator’s VT100 interface provides a wide variety of features for monitoring and
administering the unit’s activities.The initial display of the VT100 interface shows the Main
Edit Menu and a group of status windows. You configure several system administration
parameters from the Main Edit Menu. The status windows display a variety of information
about the operation of your DSL Terminator. You have access to DO commands, which enable
you to perform additional tasks. To perform any of the administrative tasks, you must activate
administrative permissions.
The VT100 interface provides access to the terminal-server command-line interface, which
features a large assortment of powerful commands. For example, you can view the DSL
Terminator’s routing tables and statistical information. You can access detailed information
about the unit’s IP routing table and Frame Relay connections. You can also use the
administrative commands Ping, Traceroute, and Telnet to establish and test connectivity. You
can manually add, delete, or change routes in your IP routing table. Descriptions of the
commands available through the terminal-server command-line interface form the major part
of this chapter.
Note: You can manage the DSL Terminator from your workstation by establishing a Telnet
session and logging in with sufficient administrative privileges. You can also use Telnet to
manage remote DSL Terminator units.

System Administration
Activating administrative permissions
Activating administrative permissions
Before you can use the administrative commands and profiles, you must log in as superuser by
activating a Security profile that has sufficient permissions (for example, the Full Access
profile.) Proceed as follows:
1
Press Ctrl-D. The DO menu appears:
DO...
>0=Esc
P=Password
C=Close TELNET
E=Termsrv
D=Diagnostics
2
Press P (or select P=Password).
3
In the list of Security profiles that opens, select Full Access.
The DSL Terminator prompts you for the Full Access password:
00-30p Security
Enter Password:
[]
Press > to accept
4
Type the password assigned to the profile, and press Enter. The default password for the
Full Access login is Ascend.
When you enter the correct password, the DSL Terminator displays a message informing
you that the password was accepted and that the DSL Terminator is using the new security
level:
Message #119
Password accepted.
Using new security level.
If the password you enter is incorrect, the DSL Terminator prompts you again for the
password.
Note: The first task you should perform after logging in as the superuser is to assign a new
password to the Full Access profile.

Understanding the administrative parameters
This section provides some background information about the administrative options. For
more details about the parameters, see the DSL Terminator Reference. For background
information about additional parameters that appear in the System profile, see the Network
Configuration Guide for your DSL Terminator.
Name
The Name parameter specifies the system name, which can consist of up to 16 characters.
Keeping the name simple (no special characters) is a good idea because it is used in negotiating
bridged PPP, AIM, and BONDING connections.
Location and Contact
The Location and Contact settings are SNMP readable and settable. The Location parameter
specifies the unit’s location, and the Contact parameter specifies the name of the person to
contact concerning any problems with the unit. You can enter up to 80 characters.
DSL Terminator Administration Guide
1-3
System Administration
System administration parameters
Date and Time
The Date and Time parameters set the system date and time. If you are using Simple Network
Time Protocol (SNTP), the DSL Terminator can maintain its date and time by accessing the
SNTP server. (For details, see the Network Configuration Guide for your DSL Terminator.)
Term rate and Console
The Term Rate parameter specifies the transmission rate for communications with your
terminal-emulation program. Any rate higher than 9600 can cause transmission errors.
Also verify that the data rate of your terminal-emulation program is set to 9600 bps or lower.
Remote Mgmt
You can set Remote Mgmt=Yes to enable management of the DSL Terminator from a WAN
link.
Log out parameters
The Auto Logout parameter specifies whether to log out and go back to default privileges upon
loss of DTR from the serial port. Idle Logout specifies the number of minutes an
administrative login can remain inactive before the DSL Terminator logs out and hangs up.
DS0 minimum and maximum resets
A DS0 minute is the online usage of a single 56-Kbps or 64-Kbps switched channel for one
minute. For example, a 5-minute, 6-channel call uses 30 DS0 minutes.
The DS0 Min Rst parameter specifies when the DSL Terminator should reset accumulated
DS0 minutes to 0 (zero). You can also use this parameter to specify that the DSL Terminator
should disable the timer altogether.
The Max DS0 Mins parameter specifies the maximum number of DS0 minutes a call can be
online. When the usage exceeds the maximum specified by the Max DS0 Mins parameter, the
DSL Terminator cannot place any more calls, and it takes any existing calls offline.
High-bit-error parameters
The High BER parameter specifies the maximum bit-error rate for any PRI line. The bit-error
rate consists of the number of bit errors that occur per second. The number that comes after the
double asterisks specifies the power of 10 for the current ratio of error bits to total bits.
The High BER Alarm parameter specifies whether the back-panel alarm relay closes when the
bit-error rate exceeds the value specified by the High BER parameter.

Terminal-server command-line interface
The terminal-server command-line interface provides commands for monitoring networks,
initiating sessions, and administering the system.
Accessing the interface
You can start a terminal-server command-line session if you have administrative privileges.
(For more information, see “Activating administrative permissions” on page 1-2). You can
start a session using one of the following methods:
•
From the main VT100 menu, select System > Sys Diag > Term Serv, and press Enter.
•
In the Main Edit Menu, press Ctrl-D to open the DO menu, and select E=Termsrv.
•
Enter the following keystroke sequence (Escape key, left bracket, Escape key, zero) in
rapid succession:
Esc [ Esc 0
If you have sufficient privileges to invoke the command line, the DSL Terminator displays a
command-line prompt. For example:

Commands for use by terminal-server users
The following commands must be enabled for use in Ethernet > Mod Config > TServ Options.
If they are enabled, login users can initiate a session by invoking the commands in the
terminal- server interface.
telnet
rlogin
telnet [ -a|-b|-t ] <host-name> [ <port-number> ]
rlogin [ -l user -ec ] <host-name> [ -l user ]
These commands initiate a session with a host or modem, or toggle to a different interface that
displays a menu selection of Telnet hosts.
Telnet
The Telnet command initiates a login session to a remote host. It uses the following format:
where telnet [-a|-b|–t] hostname [port-number]
•
–a | –b | –t are optional arguments specifying ASCII, Binary, or Transparent mode,
respectively. If one of the arguments is entered, it overrides the setting of the Telnet Mode
parameter.
In ASCII mode, the DSL Terminator uses standard 7-bit mode. In Binary mode, the DSL
Terminator tries to negotiate 8-bit mode with the server at the remote end of the
connection, so that the user can send and receive binary files by means of 8-bit file transfer
protocols. In transparent mode, either of the other modes can be used without specifying
the node.
•
hostname can be the remote system’s DNS name if you have configured DNS. If you
have not, you must specify the IP address of the remote system.
•
port-number is an optional argument specifying the port to use for the session. The
default is 23, which is the port number of the well-known port for Telnet.
For example, if your DNS table has an entry for myhost, you can open a telnet session with
that host as follows:
ascend% telnet myhost
If you do not configure DNS, you must specify the host’s IP address instead. There are also
several options in the Ethernet > Mod Config > TServ Options subprofile that affect Telnet; for
example, if you set Def Telnet to Yes, you can just type a hostname to open a Telnet session
with that host:
ascend% myhost
Another way to open a session is to invoke Telnet first, then enter the Open command at the
Telnet prompt. For example:
DSL Terminator Administration Guide
1-7
System Administration
Terminal-server command-line interface
ascend% telnet
telnet> open myhost
When your screen displays the telnet> prompt, you can enter any of the Telnet commands
described in “Telnet session commands” on page 1-8. You can quit the Telnet session at any
time by entering the Quit command at the Telnet prompt:
telnet> quit
Note: During an open Telnet connection, press Ctrl-] to display the telnet> prompt and
the Telnet command-line interface. Any valid Telnet command returns you to the open session.
Note that Ctrl-] does not function in binary mode Telnet. If you log into the DSL Terminator by
Telnet, you might want to change the escape sequence from Ctrl-] to a different setting.
Telnet session commands
The commands in this section can be entered at the Telnet prompt during an open session. To
display the Telnet prompt while logged in to a host, press Ctrl-] (hold down the Control key
and type a right bracket). To display information about Telnet session commands, use the Help
or ? command. For example:
telnet> ?
To open a Telnet connection after invoking Telnet, use the Open command. For example:
telnet> open myhost
To send standard Telnet commands such as Are You There or Suspend Process, use the Send
command. For example:
telnet> send susp
For a list of Send commands and their syntax, enter the Send command with a question mark:
telnet> send ?
To specify special characters for use during the Telnet session, use the Set command. For
example:
telnet> set eof ^D
To display current settings, enter the Set All command:
telnet> set all
To display a list of Set commands, enter the Set command with a question mark:
telnet> set ?
To quit the Telnet session and close the connection, enter the Close or Quit command. For
example:
telnet> close
Telnet error messages
The DSL Terminator generates an error message for any condition that causes the Telnet
session to fail or terminate abnormally. The following error messages can appear:
•
1-8
no connection: host reset—The destination host reset the connection.
DSL Terminator Administration Guide
System Administration
Terminal-server command-line interface
•
no connection: host unreachable—The destination host is unreachable.
•
no connection: net unreachable—The destination network is unreachable.
•
Unit busy. Try again later.—The host already has open the maximum number
of concurrent Telnet sessions.
Rlogin command
The Rlogin command initiates a login session to a remote host. The command has the
following format:
rlogin [-echar] hostname [-1username]
where:
•
-echar sets the escape character to char. For example:
rlogin -e$ 10.2.3.4
The default escape character is a tilde (~).
•
hostname can be the remote system’s DNS name if you have configured DNS. If oyu
have not, you must specify the IP address of the remote system.
•
-lusername specifies that you log into the remote host as username, rather than as
the name with which you logged into the terminal server. (If you logged in through
RADIUS or TACACS, you must be prompted for this option.) If you can specify this
option on the command line, you can enter it either before or after the hostname argument.
For example, the following two lines perform identical functions:
rlogin -l jim 10.2.3.4
rlogin 10.2.3.4 -l jim
To terminate the remote login, choose the Exit command at the remote system’s prompt. Or,
you can press the Enter key, then type the escape character followed by a period.
<CR><ESC-CHAR><PERIOD>
For example, to terminate a remote login that was initiated with the default escape character (a
tilde), press the Enter key, then the ~ key, then the . key.
TCP
The TCP command initiates a login session to a remote host. The command has the following
format:
tcp hostname [port-number]
where:
•
hostname can be the remote system’s DNS name if you have configured DNS. If oyu
have not, you must specify the IP address of the remote system.
•
port-number specifies the port to use for the session. The port number typically
indicates a custom application that runs on top of the TCP session. For example, port
number 23 starts a Telnet session. However, terminating the Telnet session does not
terminate the raw TCP session.
When the raw TCP session starts running, the DSL Terminator displays the word
connected. You can then use the TCP session to transport data by running an application on
DSL Terminator Administration Guide
1-9
System Administration
Terminal-server command-line interface
top of TCP. You can hang up the device at either end to terminate the raw TCP session. If you
are using a remote terminal-server session, ending the connection also terminates raw TCP.
If a raw TCP connection fails, the DSL Terminator returns one of the following error
messages:
•
Cannot open session: hostname port-number—You entered an invalid or
unknown value for hostname, you entered an invalid value for port-number, or a
port number was required and you failed to enter it.
•
no connection: host reset— The destination host reset the connection.
•
no connection: host unreachable— The destination host is unreachable.
•
no connection: net unreachable— The destination network is unreachable.
Administrative commands
The following commands (shown as they appear in the Help display) are useful for system
administration:
remote
remote <station>
set
Set various items. Type ’set ?’ for help
show
Show various tables. Type ’show ?’ for help
kill
terminate session
Remote
After an MP+ connection has been established with a remote station (for example, by using the
DO Dial command), you can start a remote management session with that station by entering
the Remote command in the following format:
remote station
For example:
ascend% remote lab17gw
During the remote management session, the user interface of the remote device replaces your
local user interface, as if you had opened a Telnet connection to the device. You can enter Ctrl-\
at any time to terminate the Remote session. Note that either end of an MP+ link can terminate
the session by hanging up all channels of the connection.
The argument to the Remote command is the name of the remote station. It must match the
value of a Station parameter in a Connection profile that allows outgoing MP+ calls, or the
user-id at the start of a RADIUS profile set up for outgoing calls.
Note: A remote management session can time out because the traffic it generates does not
reset the idle timer. Therefore, the Idle parameter in the Connection profile at both the calling
and answering ends of the connection should be disabled during a remote management session,
and restored just before exiting. Remote management works best at higher terminal speeds.
At the beginning of a remote management session, you have privileges set by the default
Security profile at the remote end of the connection. To activate administrative privileges on
1-10
DSL Terminator Administration Guide
System Administration

the remote station, activate the appropriate remote Security profile by using the DO Password
command (as described in “Activating administrative permissions” on page 1-2).
The DSL Terminator generates an error message for any condition that causes the test to
terminate before sending the full number of packets. The following error messages can appear:

System Administration
Terminal-server command-line interface
term = vt100
dynamic password serving = disabled
To specify a terminal type other than VT100, use the Set Term command.
The Set Password command puts the terminal server in password mode, in which a third-party
ACE or SAFEWORD server at a secure site can display password challenges dynamically in
the terminal-server interface. When the terminal server is in password mode, it passively waits
for password challenges from a remote ACE or SAFEWORD server. The Set Password
command applies only when using security card authentication. Enter the command as
follows:
ascend% set password
Entering Password Mode...
[^C to exit] Password Mode>
To return to normal terminal-server operations and thereby disable password mode, press
Ctrl-C.
Note that each channel of a connection to a secure site requires a separate password challenge,
so for multichannel connections to a secure site, you must leave the terminal server in
password mode until all channels have been established. The APP Server utility provides an
alternative way to allow users to respond to dynamic password challenges obtained from
hand-held security cards.
The Set FR commands enable you to bring down the nailed connection specified in the named
Frame Relay profile. The connection reestablished within a few seconds. The Set Circuit
commands let you activate or deactivate a Frame Relay circuit.

DO commands in alphabetic order
This section describes the DO commands in detail.
Close Telnet (DO C)
The DO Close Telnet command closes the current Telnet session. You must be running a Telnet
session from the DSL Terminator’s terminal-server interface.
Diagnostics (DO D)
The DO D command invokes diagnostics mode. The user must have sufficient privileges in the
active Security profile. In diagnostics mode, the VT100 interface displays a command-line
prompt:
>
Use the help ascend command to display a list of diagnostic commands:
> help ascend
To exit diagnostics mode and return to the VT100 interface, enter the Quit command:
> quit
Esc (DO 0)
The DO ESC command exits the DO menu.
Password (DO P)
The DO Password command enables you to log into the DSL Terminator. During login, you
select and activate a Security profile. The Security profile remains active until you log out or
replace it by activating a different Security profile, or until the DSL Terminator automatically
logs you out. The DSL Terminator can have several simultaneous user sessions and, therefore,
several simultaneous Security profiles.
To log into the DSL Terminator, use the DO P command. You can log in or log out from any
menu. Whenever you select the DO P command, a list of Security profiles appears. Select the
desired profile with the Enter or Right Arrow key, and enter its corresponding password when
prompted. If you enter the correct password for the profile, the security of the DSL Terminator
is reset to the Security profile you have selected.
If you select the first Security profile, Default, simply press Enter or Return when prompted for
a password. The password for this profile is always null.
If you are operating the DSL Terminator locally and you want to secure the DSL Terminator
against the next user, use the DO P command and select the first profile, Default. Typically, the
Default profile has been edited to disable all operations you wish to secure.
The DSL Terminator logs you out to the Default profile if any one of the following situations
occurs:

VT100 Interface DO Commands
DO commands in alphabetic order
•
You end a console session.
•
You exceed the time set by the Idle Logout parameter in the System profile.
Auto Logout=Yes in the System profile and you are connected to
the VT100 control port.
A single Security profile can be used simultaneously by any number of users. If both you and
another user enter the same password, you both get the same Security profile and can perform
the same operations. If each of you uses a different password to log in, each of you gets a
separate Security profile with separate lists of privileges.
If you edit a Security profile, the changes do not affect anyone who is logged in and using that
profile. However, the next time someone logs in and uses that profile, security for the user will
be limited according to the changes you have made.
For related information, see the Auto Logout and Idle Logout parameters in the DSL
Terminator Reference.
Termserv (DO E)
The DO Termserv command invokes the terminal-server command-line interface. The user
must have sufficient privileges in the active Security profile. In terminal-server mode, the
VT100 interface displays a command-line prompt. By default the prompt is:
ascend%
Enter the Help command to display a list of terminal-server commands:
ascend% help ascend

Administering DS3-ATM cards
Important information about DS3 card operation can be obtained from the status window. A
number of diagnostic commands are available to assist in troublshooting DS3 problems.
Interpreting status windows for the DS3 card
Use status profiles on the VT100 interface to perform diagnositcs on the DS3-ATM card. you
can view available lines, each line’s status, and any error on each line. The DSL Terminator
displays available lines in the Main Edit Menu:
Main Edit Menu
00-000 System
10-000 Net/DS3-ATM
20-000 Net/DS3-ATM

The DSL Terminator dislays the status of the available lines in the Line Status profile:
10-000 Net/DS3-ATM
10-100 Line Status
10-200 Line Errors
When you select Line Status, the DSL Terminator displays the current status of that
Net/DS3-ATM line. An asterik (*) character in any column indicates that the state applies. A
hyphen (- ) character in any column indicates that the state does not apply. The following table
describes the possible states for Net/DS3-ATM Line Status:
State
Description
ACT
On indicates multipoint established.
OOF
On indicates the near end is in an out-of-frame condition.
RED
On indicates the line is not connected, improperly
configured, experiencing a very high error rate, or
supplying inadequate synchronization.
YEL
On indicates the card is receiving a yellow-alarm from far
end.
AIS

Using diagnostic commands
The DO menu is a context-sensitive list of commands that appears when you press Ctrl-D. The
commands in the DO menu vary, depending on the context in which you invoke it. For
example, if you press Ctrl-D in a Connection profile, the DO menu looks similar to the
following:
DO…
>0=ESC
1=Dial
P=Password
S=Save
E=Termserv
D=Diagnostics
To execute a DO command, press and release the Ctrl-D on a VT100 system, and then press
and release the next key in the sequence (such as 1 to invoke the Dial command.) On a VT100
terminal, the PF1 function key is equivalent to Ctrl-D.
In Diagnostics, you may use the following supported command:
> atmframer slot-[ t | d | l | r | s | c ]
Here are the options and effects for each of the atmframer slot commands:
Option
Effect
-t
Toggles debug output.
-d
Dump ATM framer chip status information. The information this
option displays is also available from the status lights on the card and
in the DS3-ATM-Stat profile.

Looping back the DS3-ATM line
For diagnostics, you might want to loopback the DS3 interface by using the Loopback
parameter in the DS3-ATM profile. While the interface is looped back, normal data traffic is
interrupted. The Loopback parameter in the DS3-ATM profile supports the following settings:
Value
Description
No-Loopback
The default, specifies that the DS3 line is operating normally
Facility-Loopback
During a facility loopback, the DS3 card returns the signal it
receives on the DS3 line.
Local-Loopback
During a local loopback, the DS3 receive path is connected to
the DS3 transmit path at the D3 multiplexer. The transmitted
DS3 signal is still sent to the network as well.

Looping back the OC3-ATM line
For diagnostics, you might want to loopback the OC3 interface by using the Loopback
parameter in the Net/OC3-SMF-ATM (Net/OC3-UTP-ATM)> Line Diag profile. As long as
the interface is looped back, normal data traffic is interrupted. The Loopback parameters
supports the following options:
Value
Description
None
The default, specifies that the OC3 line is operating normally.
Remote
During a facility loopback, the OC3 card returns the signal it
receives on the OC3 line.
Local
During a local loopback, the OC3 receive path is connected to
the OC3 transmit path at the D3 multiplexer. The transmitted
OC3 signal is still sent to the network as well.
You can view the line statistics by using the OC3Framer command. For information about this
command, see “Using the OC3Framer command” on page 3-11.

ASCII file.
8
Turn off the autotype feature.
Sys Reset
The Sys Reset command restarts the DSL Terminator and clears all calls without disconnecting
the device from its power source. The DSL Terminator logs out all users and returns user
security to its default state. In addition, the DSL Terminator performs Power-On Self Tests
(POSTs) when it restarts. The POSTs are diagnostic tests.
A system reset of an DSL Terminator causes momentary loss of T1 framing (that is, the
data-encapsulation format), and the T1 line might shut down. The feedback from the DSL
Terminator to the switch will be incorrect until T1 framing is reestablished.
To perform a system reset, proceed as follows:
4-2
DSL Terminator Administration Guide
Diagnostic Commands
System diagnostic command reference

The DSL Terminator checks system memory, configuration, installed modules, and T1
connections. The alarm relay remains closed while the POST is running and opens upon
successful completion of the test, at which time the following message appears:
Power-On Self Test PASSED
Press any key...
3
Press any key to display the Main Edit Menu.
Term Serv
The Term Serv command starts a terminal-server session. The system displays the terminalserver command-line prompt (by default, ascend%). For information about the terminalserver commands, enter a question mark at the prompt. For more details about the terminalserver interface, see the Network Configuration Guide or Reference for your DSL Terminator.
Upd Rem Cfg
The Upd Rem Cfg (Upload Remote Configuration) command opens a connection to a
RADIUS server to upload the DSL Terminator terminal-server banner, list of Telnet hosts, IP
static routes, IP address pool, and other configuration information from the RADIUS user file.
The DSL Terminator retrieves configuration from RADIUS at system startup or by use of this
command.
When you highlight Upd Rem Cfg and press Enter, the DSL Terminator opens a connection to
the RADIUS server and uploads the configuration information.
When you upload this remote configuration information, note the following:
•
The DSL Terminator reads Dialout-Framed-User entries with the password ascend.
•
The Upd Rem Cfg command does not update the terminal-server banner or list of Telnet
hosts if the Remote Conf parameter is set to No.
•
If the Ascend-Authen-Alias attribute is defined in RADIUS, the Upd Rem Cfg command
also updates the DSL Terminator system name used when establishing PPP calls.

Navigating the status windows
To make a status window active, press the Tab key until that window is highlighted by a thick
border. The Tab key moves the active window in sequence from left to right, top to bottom, and
then returns to the Main Edit window (the menu).
To scroll the selections within a status window, Tab to the window, then use the Up Arrow or
the Down Arrow key to scroll the window. To access a submenu, use the Right Arrow key, and
to return to the original menu use the Left Arrow key.
Some of the status windows contain more information than can be displayed in the small
window. A lowercase v in the lower-right corner of a window, indicates that more information
is available. You can scroll through additional information if you make the window active.
Default status window displays
You can set the Status parameters in the System profile to specify which status windows are
displayed when the DSL Terminator powers up. For descriptions of all of the codes and
information that can be displayed in each window, see “Status-window reference in alphabetic
order” on page 5-5.
Note: Depending on your DSL Terminator configuration, some of these status windows will
appear by default and some may not. If a status window does not appear by a default, each of
the descriptions below instruct you how to display the menu from any status window. If the
status window described is already displayed on your VT100 interface, all you may want to do
is scroll through the submenus to view its contents.

The Sessions window shows the number of active bridging/routing and modem (terminal
server) sessions. When this window is active, you can scroll down to see the name, address, or
Calling Line ID (CLID) of each connected device. Each line starts with a one-character
session-status indicator. For example, O means online. For terminal-server sessions, the
modem number is identified.
You can also display the Sessions window, by tabbing to any status window, and using the
arrow keys to access the Ethernet > Sessions window.
The system message log provides a log of up to 32 of the most recent system events. To display
the System Message Log window, tab to any status window, then use the arrow keys to access
the System > Message Log window.
Use an arrow key to scroll up (previous messages) or down (later messages). The Delete key
clears all the messages in the log. The message log window is organized as follows:
•
The first line shows the menu number and the time the most recently logged event
occurred.

seconds to show the number of days, hours, minutes, and seconds the DSL Terminator has
been operating. For example:
Up: 12:17:18:26
When the Sys Options window is active, you can use the arrow keys to scroll down and display
the list of system options. For example, some system options that can appear are the software
load name, various installed-software options (such as Frame Relay, AIM, and BONDING),
and the AuthServer and AcctServer options, which specify the IP addresses of the RADIUS (or
TACACS) authentication server and the RADIUS accounting server.
You can also display the System Options window, by tabbing to any status window, then using
the arrow keys to access the System > Sys Option window.
The last status window contains the Main Status Menu, a hierarchical menu that contains an
entry for each line or installed card in the DSL Terminator. The structure of the Main Status
Menu exactly follows the Main Edit Menu (the top-level configuration menu).
When the window that displays the Main Status Menu is active, the menu works like the Main
Edit Menu. Use the arrow keys to scroll to a particular status menu. Then press the Enter key to
open that menu and the Escape key to close it.
Specifying which status windows appear
You can specify which status windows the VT100 interface displays. The total number of
status window that can be displayed is limited to eight. You can use the system configuration
profile to choose which status windows are displayed in the eight available positions.For
details about the windows you can choose to display and the information in each one, see
“Status-window reference in alphabetic order” on page 5-5.
To specify which status windows appear on the VT100 interface, proceed as follows:
1
From the Main Edit Menu, select System > Sys Config.
2
Using the down arrow key, navigate to the list of eight status window parameters Status
1 through Status 8 and select the desired status parameter.
3
Press the right arrow key and enter the number of the status window that you wish to
display in that position.
Note: Every menu and submenu has an identifying number, for example, 20-100, or
20-200. You can scroll through the Main Status Menu to get the identifying status
numbers.
4
Save and close the System profile.
When the DSL Terminator resets, the status windows appear with the new selections.

VT100 Interface Status Windows
Status-window reference in alphabetic order
CDR window
Call Detail Reporting (CDR) provides a database of information about each call, including
date, time, duration, called number, calling number, call direction, service type, associated
inverse-multiplexing session, and port. Because the network carrier bills for bandwidth on an
as-used basis, and bills each connection in an inverse multiplexed call separately, you might
want to use CDR to understand and manage bandwidth usage and the cost of each inversemultiplexed session.
You can arrange the information to create a wide variety of reports, which can be based on
factors such as individual call costs, inverse-multiplexed WAN-session costs, costs on an
application-by-application basis and bandwidth usage patterns over specified time periods.
With a better understanding of your bandwidth usage patterns, you can make any necessary
adjustments to the ratio of switched to nailed bandwidth between network sites.
Like the DSL Terminator message logs, CDR shows the most recent session event. The DSL
Terminator generates new CDR messages as events occur. However, unlike a log, the DSL
Terminator does not store past CDR events. The CDR window is primarily a source of data
captured by external devices.
To display the CDR window, tab to any status window, then use the arrow keys to access the
System > CDR window.
Following is a sample four-line CDR display:
00-400 CDR
93:05:28:10:33:52
OR 025 384KR 02-01
15105551212
The first line displays the status-window number and title.
The second line displays the time at which the event occurred, in the following format:
year:month:day:hour:minute:second
The third line displays the following items of information about the CDR event in the order
shown:
Item

•
OR—Originated (outgoing call)
•
AN—Answered (incoming call)
•
AP—Assigned to Port or module (incoming call)
•
CL—Cleared
•
OF—Overflowed
All events except OF are associated with calls. OF indicates that the
CDR buffer overflowed because events occurred faster than the DSL
Terminator could report them.

Description
CDR event ID
The DSL Terminator creates a new event ID for every DS0 channel
originating a connection. The event ID number, range, from 0 to 255.
Events after 255 start the count again at 0. In addition, CDR creates a
new event ID for every change in a channel’s status. Because a DSL
Terminator call can consist of several channels, the DSL Terminator
can generate multiple CDRs for every change in call status.
Data service in use
Indicates the data service, using values nearly identical to those
available to the Data Svc parameter in the Call profile. The only
difference is that the Data Svc values 384K/H0 and 1536K correspond
to the CDR data service values 384K and 1536KR, respectively.
Slot-port address
The address at which event occurred. For example, if the event
occurred on the first port of a Host/6 card installed in slot 3, the
slot-port address is 03-01.
The fourth line displays either the dialed or called-party phone number. If the event description
on line 3 is OR (outgoing call), the number dialed appears. If the event description on line 3 is
AN (incoming call), the called-party number appears. To get the called-party number on
incoming calls, you must have DNIS service from your WAN provider. In some cases, the
called-party number is not delivered, (for example, when the DSL Terminator is behind some
types of PBX).
For related information, see the Data Svc parameter in the DSL Terminator Reference.
Dyn Stat window (dynamic status)
The Dynamic Status (Dyn Stat) window shows the name, quality, bandwidth, and bandwidth
utilization of each online, multichannel, PPP connection with dynamic bandwidth
management. To display the Dyn Stat window, tab to any status window, then use the arrow
keys to access the Ethernet > Dyn Stat window.
Following is the Dyn Stat display for an Ethernet module in slot 9:

ALU 23%
Note: Press the Down Arrow key to see additional online multichannel PPP connections.
The first line of the Dyn Stat window shows the window number and the name of the current
Connection profile. If no connection is currently active, the window name appears instead.
The second line lists the quality of the link and the amount of time the link has been active.
When a link is online more than 96 hours, the DSL Terminator reports the duration in number
of days. The link quality can have one of the following values:
•
Good—The current rate of CRC errors is less than 1%.
•
Fair—The current rate of CRC errors is between 1% and 5%.
•
Marg—The current rate of CRC errors is between 5% and 10%.
•
Poor—The current rate of CRC errors is more than 10%.
DSL Terminator Administration Guide

VT100 Interface Status Windows
Status-window reference in alphabetic order
•
N/A—The link is not online.
The third line of the Dyn Stat window shows the current data rate in Kbps, and how many
channels this data rate represents.
The fourth line displays the following values:
•
CLU—Current Line Utilization. The percentage of bandwidth currently being used by the
call for transmitted data, divided by the total amount of bandwidth available.
•
ALU—Average Line Utilization. ALU is the average amount of available bandwidth used
by the call for transmitted data during the current history period as specified by the Sec
History and Dyn Alg parameters.
Ether Opt window
The Ethernet Options (Ether Opt) window lists the type of Ethernet interface specified in the
Ethernet I/F parameter, and its MAC address. To display the Ether Opt window, tab to any
status window, then use the arrow keys to access the Ethernet > Ether Opt window.
Following is an example of an Ether Opt display for an Ethernet module in slot 9:
90-600 Ether Opt
>I/F: COAX
Adrs: 00c07b322bd8
The interface type may be AUI, UTP, or COAX. The MAC address is a 6-byte hexadecimal
address assigned to the Ethernet controller by the manufacturer. For related information, see
the entry for the Ethernet I/F parameter in the DSL Terminator Reference.
Ether Stat window
The Ethernet Status (Ether Stat) window shows the number of Ethernet frames received and
transmitted and the number of collisions at the Ethernet interface. To display the Ether Stat
window, tab to any status window, then use the arrow keys to access the Ethernet > Ether Stat
window.
For example, the following screen shows the Ether Stat display for an Ethernet module in slot
9:
90-400 Ether Stat
>Rx Pkt:
106
Col:
0
Tx Pkt:
118
The screen shows the following fields:
•
Rx Pkt—Number of Ethernet frames received on the Ethernet interface
•
Col—Number of collisions detected at the Ethernet interface
•
Tx Pkt—Number of Ethernet frames transmitted over the Ethernet interface
The counts return to 0 (zero) when the DSL Terminator is switched off or reset. Otherwise, the
counts continuously increase, up to the maximum allowed by the display.

Table 5-4. Warning log messages (continued)
Message
Description
Call Disconnected
The call has ended unexpectedly.
Call Refused
An incoming call could not be connected to the specified AIM port,
digital modem, packet-handling module, or terminal server because
the resource was busy or otherwise unavailable.
Dual Port req’d
The call could not be placed because one or both ports of the
dual-port pair were not available.
Far End Hung Up
The remote end terminated the call normally.
Incoming Glare
The DSL Terminator could not place a call because it saw an
incoming glare signal from the switch. Glare occurs when you
attempt to place an outgoing call and answer an incoming call
simultaneously. If you receive this error message, you have probably
selected incorrect settings in the Line N profile.
Internal Error
Call setup failed because of a lack of system resources. If this type of
error occurs, notify Lucent Customer Service.
LAN security error
Appears after Incoming Call but before Call Terminated if a PPP,
MP+, terminal-server, or Combinet session has failed authentication,
another session by the same name already exists, or the time-out
period for RADIUS/TACACS authentication has been exceeded. For
details, see the entry for the Auth Timeout parameter in the DSL
Terminator Reference.
Network Problem
The call setup was faulty because of problems within the WAN or in
the Line N profile configuration. The telco might be experiencing a
problem.
No Chan Other
End
No channel was available on the remote end to establish the call.
No Channel Avail
No channel was available to dial the initial call.

Message
Description
Not FT1-B&O
The local DSL Terminator attempted to connect an FT1-B&O call to
the remote end, but the call failed because the call type at the remote
end was not FT1-B&O.
Remote Mgmt
Denied
The DSL Terminator rejected a request to run the remote DSL
Terminator by AIM remote management because the Remote Mgmt
parameter in the System profile at the remote end is set to No.
Request Ignored
The DSL Terminator denied a request to manually change bandwidth
during a call because the Call Mgm parameter in the Call profile is
set to Dynamic. With this setting, the DSL Terminator allows only
automatic bandwidth changes.
Wrong Sys Version
The remote-end product version was incompatible with the version
of the local DSL Terminator. The software version appears in the Sys
Options status window.

line 4 displays the phone number for the first connection. Only the
phone number appears. The parameter name, Phone Number, does
not.
Name
When the message in line 3 is either LAN session up or LAN
session down, line 4 displays the remote end’s name. If the
session is a Combinet bridging link, the MAC address is displayed. If
the session is a PPP link, either the remote end’s system name (as
specified by the Name parameter in the System profile) or IP address
(as specified by the IP Adrs parameter in the Ethernet profile) is
displayed. The IP address is displayed only if the system’s name is
not known.

Sessions window
The Sessions status window indicates the number of active bridging/routing links or remote
terminal-server sessions. An online link, as configured in the Connection profile, constitutes a
single active session. A session can be PPP or Combinet-encapsulated. The DSL Terminator
treats each multichannel MP+ or MP link as a single session. The following screen shows the
display when the Ethernet module is installed in Slot 5:
50-100 Sessions

Note: For remote terminal-server sessions, the third and following lines of the Sessions
window appear in the format Modem slot:position, where slot specifies the slot of the
active digital modem, and position is a number indicating the position of the modem in that
slot.
Syslog window
Syslog is not a DSL Terminator status display, but an IP protocol that sends system-status
messages to a host computer, known as the Syslog host. The Log Host parameter in the
Ethernet profile specifies the Syslog host, which saves the system-status messages in a log file.
The messages are derived from two sources—the Message Log display and the CDR display.
Note: See the UNIX man pages about logger(1), syslog(3), syslog.conf(5),
and syslogd(8) for details of the syslog daemon. The Syslog function requires UDP port
514.
Level 4 and Level 6 syslog messages
The data for Level 4 (warning) and Level 6 Syslog messages is derived from the Message Log
displays. Level 4 and Level 6 messages are presented in the following format:
ASCEND: slot-n port-n | line-n, channel-n, text-1
ASCEND: slot-n port-n | line-n, channel-n, text-2
The device address (slot, port or line, and channel) is followed by two lines of text, which are
displayed on lines 3 and 4 of the Message Log window. The device address is suppressed when
it is not applicable or unknown.

not applicable or is unknown.
ata-svcK
The data service in use.
phone-N
The phone number.
Example
Because the date, type, and name of a syslog message are added by the Syslog host, the DSL
Terminator does not include that data in the message format. Following are sample Syslog
entries from a Syslog host:
Oct 21 11:18:07 marcsDSL Terminator ASCEND: slot 0\ port 0, line
1, channel 1, \
No Connection
Oct 21 11:18:07 marcsDSL Terminator ASCEND: slot 4\ port 1, Call
Terminated
Oct 21 11:19:07 marcsDSL Terminator ASCEND: slot 4\ port 1, Outgoing Call, 123
In this example, three messages are displayed for the system marcsAscend. Notice that the
back-slash (\) indicates the continuation of a log entry onto the next line.
Disconnect codes and Progress codes
If the Syslog option is set, a Call-Close (CL) message is sent to the Syslog daemon whenever
a connection is closed. Additional information about the user name, Disconnect code, Progress
code, and login host is appended to each CL message. The CL message uses the following
format:

The backoff queue error message in the Syslog file
The DSL Terminator keeps accounting records until the accounting server acknowledges them.
The backoff queue stores up to 100 unacknowledged records. If the unit never receives an
acknowledgment to an accounting request, it eventually runs out of memory. To prevent this
situation, the DSL Terminator might delete an accounting record and send the following error
message to the Syslog file:
Backoff Q full, discarding user username
This error generally occurs for one of the following reasons:
•
You enabled RADIUS accounting on the DSL Terminator but not on the RADIUS server.
•
The Accounting Port or Accounting Key value is incorrect. The Accounting Key value
must match the value assigned in the RADIUS clients file or in the TACACS+
configuration file.
•
You are using the Livingston server instead of the Lucent server.
Syslog messages initiated by a SecureConnect Manger firewall
Depending on the settings specified in SecureConnect Manager (SCM), the DSL Terminator
might generate Syslog messages about packets detected by a firewall. By default, SCM
DSL Terminator Administration Guide
5-23
VT100 Interface Status Windows

Description
Date
The date the message was logged by Syslog
Time
The time the message was logged by Syslog.
Router name
The router this message was sent from.
Interface
The name of the interface (ie0, wan0, and so on) unless a call filter logs
the packet as it brings up the link, in which case the word call appears.
Message
The message format has a number of fields, one or more of which may be
present. See Table 5-8 for field definitions.
The message fields appear in the following order:
protocol local direction remote length frag log tag
Table 5-8. Syslog message fields for SecureConnect firewalls
5-24
Field
Description
protocol
The four-character (hexadecimal) Ether Type or one of the following
network protocol names: ARP, RARP. For IP protocols, the field
contains either the IP protocol number (up to three decimal digits) or
one of the following names: IP-IN-IP, TCP, ICMP, UDP, ESP, AH.
In the special case of ICMP, the field also includes the ICMP Code
and Type ([Code]/[Type]/icmp).
local
For non-IP packets, local is the source Ethernet MAC address of
transmitted packets and the destination Ethernet MAC address of
received packets. For a nonbridged WAN connection, the two MAC
addresses are all zeros. For IP protocols, local is the IP source
address of transmitted packets and the IP destination address of
received packets. In the case of TCP or UDP, it also includes the
TCP or UDP port number ([IP-address];[port]).
direction
An arrow (<- or ->) indicating the direction in which the packet was
traveling (receive and send, respectively).
remote
For non-IP protocols, remote has the same format that local has
for non-IP packets, but shows the destination Ethernet MAC address
of transmitted packets and the source Ethernet MAC address of
received packets. For IP protocols, remote has the same format as
local but shows the IP destination address of transmitted packets
and the IP source address of received packets.
length
The length of the packet in octets (8-bit bytes).

frag
Indicates that the packet has a nonzero IP offset or that the IP
More-Fragments bit is set in the IP header.
log
Reports one or more messages based on the packet status or packet
header flags. The packet status messages include:
tag
•
corrupt—the packet is internally inconsistent
•
unreach—the packet was generated by an “unreach=” rule in
the firewall
•
!pass—the packet was blocked by the data firewall
•
bringup—the packet matches the call firewall
•
!bringup—the packet did not match the call firewall
•
syn, fin, rst—TCP flag bits. The syn bit is only
displayed for the initial packet, which has the syn flag set
instead of the ack flag set.

Managing IP routes and sessions
This section describes how to monitor TCP/IP/UDP and related information using the
terminal-server command-line interface. Using various IP route commands you can display
and change the routing table, display routing statistics and display information about the
operation of various routing protocols.
To invoke the terminal-server interface, select System > Sys Diag > Term Serv and press Enter.
The terminal-server command-line prompt appears: ascend%.
Working with the IP routing table
The terminal-server IProute commands display the routing table and enable you to add or
delete routes. The changes you make to the routing table by using the IProute command last
only until the DSL Terminator is reset. To display the IProute commands, enter the IP route
command with a question mark:
ascend% iproute ?

Display help information
iproute add <destination/size> <gateway> [ pref ] [ m
iproute delete <destination/size> <gateway> [ proto ]

Displaying the routing table
You can use either the IProute Show command or the Show IP Routes command to display the
IP routing table: For example:

The private loopback route shown is a host route with the Ethernet address. It is private, so it is
not be advertised. The private route to the broadcast address is used in cases in which the
router must to broadcast a packet, but the route is otherwise unconfigured. It is typically used
when the DSL Terminator is trying to locate a server on a client machine to handle challenges
for a token security card.
Adding an IP route
To add a static route that will be lost when the DSL Terminator resets enter the IProute Add
command in the following format:
iproute add destination gateway [metric]
where destination is the destination network address, gateway is the IP address of the
router that can forward packets to that network, and metric is the virtual hop count to the
destination network (default 8). For example, to add a route to the 10.1.2.0 network and all of
DSL Terminator Administration Guide
6-3
Network Administration
Managing IP routes and sessions
its subnets through the IP router located at 10.0.0.3/24 with a metric of 1 (the router is one hop
away), enter the following command:
ascend% iproute add 10.1.2.0 10.0.0.3/24 1
If you try to add a route to a destination that already exists in the routing table, the DSL
Terminator replaces the existing route, but only if it has a higher metric than the new route. If
you get the message Warning: a better route appears to exist, the DSL
Terminator has rejected your attempt to add a route because the routing table already contained
a route, to the same destination, with a lower metric. Note that RIP updates can change the
metric for the route.
Deleting an IP route
To remove a route from the DSL Terminator’s routing table, enter the IProute Delete command
in the following format:
iproute delete destination gateway
For example:
ascend% iproute delete 10.1.2.0 10.0.0.3/24
Note: RIP updates can add back any route you remove with IProute Delete. Also, after a
system reset, the DSL Terminator restores all routes listed in the Static Route profile.
Displaying route statistics
The Traceroute command is useful for locating slow routers or diagnosing IP routing
problems. It traces the route an IP packet follows by launching UDP probe packets with a low
Time-To-Live (TTL) value and then listening for an ICMP time exceeded reply from a router.
The Traceroute command uses the following syntax:
traceroute [-n] [-v] [-m max_ttl][-p port] [-q nqueries]
[-w waittime] host [datasize]
All flags are optional. The only required parameter is the destination hostname or IP address.
The elements of the syntax are as follows:
6-4
Syntax element
Description
-n
Print hop addresses numerically rather than symbolically and
numerically (this eliminates a name server address-to-name lookup for
each gateway found on the path).
-v
Verbose output. Lists all received ICMP packets other than Time
Exceeded and ICMP Port Unreachable are listed.
-m max_ttl
Sets the maximum time-to-live (maximum number of hops) for
outgoing probe packets. The default is 30 hops.
-p port
Set the base UDP port number used in probes. Traceroute depends on
having nothing listening on any of the UDP ports from the source to
the destination host (so that an ICMP Port Unreachable message will
be returned to terminate the route tracing). If something is listening on
a port in the default range, you can set the -p option to specify an
unused port range. The default is 33434.
DSL Terminator Administration Guide
Network Administration
Managing IP routes and sessions
-q nqueries
Set the maximum number of queries for each hop. The default is 3.
-w waittime
Set the time to wait for a response to a query. The default is 3 seconds.
host
The destination host by name or IP address.
datasize
Sets the size of the data field of the UDP probe datagram sent by
Traceroute. The default is 0. This results in a datagram size of 38 bytes
(a UDP packet carrying no data).
For example, to trace the route to the host techpubs:
ascend% traceroute techpubs
traceroute to techpubs (10.65.212.19), 30 hops, 0 byte packets
1 techpubs.eng.ascend.com (10.65.212.19) 0 ms 0 ms 0 ms
Probes start with a TTL of 1 and increase by one until one of the following conditions occurs:
•
The DSL Terminator receives an ICMP Port Unreachable message.
The UDP port in the probe packets is set to an unlikely value, such as 33434, because the
target host is not intended to process the packets. A “port unreachable” message indicates
that the packets reached the target host and were rejected.
•
The TTL value reaches the maximum value.
By default, the maximum TTL is set to 30. You can specify a different TTL by using the
–m option. For example:
ascend% traceroute -m 60 techpubs
traceroute to techpubs (10.65.212.19), 60 hops, 0 byte packets
1 techpubs.eng.abc.com (10.65.212.19) 0 ms 0 ms 0 ms
Three probes are sent at each TTL setting. The second line of command output shows the
address of the router and round-trip time of each probe. If the probe answers come from
different gateways, the address of each responding system is shown. If there is no response
within a 3 second time-out interval, the command output is an asterisk. The following
annotations can appear after the time field in a response:
•
!H—Host reached.
•
!N—Network unreachable.
•
!P—Protocol unreachable.
•
!S—Source route failed. Might indicate a problem with the associated device.
•
!F—Fragmentation needed. Might indicate a problem with the associated device.
•
!h—Communication with the host is prohibited by filtering.
•
!n—Communication with the network is prohibited by filtering.
•
!c—Communication is otherwise prohibited by filtering.
•
!?—ICMP subcode detected. This event should not occur.
•
!??—Reply received with inappropriate type. This event should not occur.
Pinging other IP hosts
The terminal-server Ping command is useful for verifying that the transmission path is open
between the DSL Terminator and another station. It sends an ICMP echo-request packet to the
DSL Terminator Administration Guide
6-5
Network Administration
Managing IP routes and sessions
specified station. If the station receives the packet, it returns an ICMP echo-response packet.
The Ping command has the following syntax:
ping [-q] [-v] [-c count] [-i sec | -I msec] [-s packetsize]
[-x src_address] host
All flags are optional. The only required parameter is the destination hostname or IP address.
The elements of the syntax are as follows:
Syntax element
Description
-q
Quiet mode. The DSL Terminator displays only the summary of all
Ping responses it has received.
-v
Verbose output. The DSL Terminator displays information from each
ping response that it receives as well as the summary of all Ping
responses. This is the default.
-c count
Specifies the number of Ping requests that the DSL Terminator sends
to the host. By default, the DSL Terminator sends continual Ping
requests until you press Ctrl-C.
-i sec
Specifies the length of time, in seconds, between Ping requests. You
can specify seconds, using the -i option, or milliseconds, using the
-I option, but not both. The default is one second.
-I msec
Specifies the length of time, in milliseconds, between Ping requests.
You can specify milliseconds, using the -I option, or seconds, using
the -i option, but not both.
-s packetsize
Specifies the size of each Ping request packet that the DSL Terminator
sends to the host. The default is 64 bytes.
-x srcaddress
Specifies a source IP address that overwrites the default source
address.
host
The destination host by name or IP address.
For example, to Ping the host techpubs:
ascend% ping techpubs
PING techpubs (10.65.212.19): 56 data bytes
64 bytes from 10.65.212.19: icmp_seq=0 ttl=255 time=0 ms
64 bytes from 10.65.212.19: icmp_seq=3 ttl=255 time=0 ms
^C
--- techpubs ping statistics --2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/DSL MAX= 0/0/0 ms
You can terminate the Ping exchange at any time by pressing Ctrl-C. When you press Ctrl-C,
the command reports the number of packets sent and received, the percentage of packet loss,
any duplicate or damaged echo-response packets, and round-trip statistics. In some cases,
round-trip times cannot be calculated.
6-6
DSL Terminator Administration Guide
Network Administration
Managing IP routes and sessions
During the Ping exchange, the DSL Terminator displays information about the packet
exchange, including the Time-To-Live (TTL) of each ICMP echo-response packet.
Note: Because the maximum TTL for ICMP Ping is 255 and the maximum TTL for TCP is
often 60 or lower, you might be able to Ping a host but be unable to run a TCP application
(such as Telnet or FTP) to that station. If you Ping a host running a version of Berkeley UNIX
earlier than 4.3BSD-Tahoe, the TTL report is 255 minus the number of routers in the
round-trip path. If you Ping a host running the current version of Berkeley UNIX, the TTL
report is 255 minus the number of routers in the path from the remote system to the station
performing the Ping.
The Ping command sends an ICMP mandatory echo-request datagram, which asks the remote
station “Are you there?” If the echo-request reaches the remote station, the station sends back
an ICMP echo-response datagram, which tells the sender “Yes, I am alive.” This exchange
verifies that the transmission path is open between the DSL Terminator and a remote station.
Configuring the DNS fallback table
The local DNS table provides a list of IP addresses for a specific host name when the remote
DNS server fails to resolve the host name. If the local DNS table contains the host name for the
attempted connection, it provides the list of IP addresses.
You create the DNS table from the Ethernet > Mod Config > DNS menu by entering up to
eight host names. Enter the IP addresses for each host through the terminal-server interface.
You can configure a maximum of 35 IP addresses for each host. If you specify automatic
updating, you only have to enter the first IP address of each host. Additional IP addresses are
added automatically.
Automatic updating replaces the existing address list for a host each time the remote DNS
server succeeds in resolving a connection to a host that is in the table. You specify how many
of the addresses returned by the remote server can be included in the new list.
On the DSL Terminator, the table, which you display from the terminal-server interface,
provides additional information for each table entry. The information is in the following two
fields, which are updated when the system matches the table entry with a host name that was
not found by the remote server:
•
# Reads (the number of reads since entry was created). This field is updated each time a
local name query match is found in the local DNS table.
•
Time of Last Read

DSL Terminator configurations control which classes of events will generate traps to be sent to
an SNMP manager, and which managers have SNMP access to the unit. A configuration
includes community strings to prevent unauthorized access. This chapter shows you how to set
up the unit to work with SNMP.
Configuring SNMP
The DSL Terminator supports Simple Network Management Tool (SNMP) on a TCP/IP
network. An SNMP management station that uses the Ascend Enterprise MIB can query the
DSL Terminator, set some parameters, sound alarms when certain conditions appear in the
DSL Terminator, and so forth. An SNMP manager must be running on a host on the local IP
network, and the DSL Terminator must be able to find that host, through either a static route or
RIP.
The DSL Terminator supports the Ascend Enterprise MIB, MIB II, and some ancillary SNMP
features. The DSL Terminator can send management information to an SNMP manager
without being polled. SNMP security uses a community name sent with each request. The DSL
Terminator supports two community names, one with read-only access, and the other with
read/write access to the MIB.
SNMP has its own password security. Lucent recommends that you set up SNMP password
security to prevent reconfiguration of the DSL Terminator from an SNMP station.
Configuring SNMP access security
There are two levels of SNMP security: community strings, which must be known by a
community of SNMP managers to access the box, and address security, which excludes SNMP
access unless it is initiated from a specified IP address. Following are the relevant parameters
(shown with sample settings):
Ethernet
Mod Config
SNMP options...
Read Comm=Ascend
R/W Comm Enable=No
DSL Terminator Administration Guide

R/W Comm=Secret
Security=Yes
RD Mgr1=10.0.0.1
RD Mgr2=10.0.0.2

WR Mgr2=10.0.0.12
WR Mgr3=10.0.0.13
WR Mgr4=10.0.0.14
WR Mgr5=10.0.0.15
For complete information about each parameter, see the DSL Terminator Reference.
Enabling SNMP Set commands
The R/W Comm Enable parameter disables SNMP set commands by default. Before you can
use an SNMP Set command, you must set R/W Comm Enable to Yes.
Note: Even if you enable R/W Comm, you must still know the read-write community string
to use a Set command.
Setting community strings
The Read Comm parameter specifies the SNMP community name for read access (up to 32
characters), and the R/W Comm parameter specifies the SNMP community name for
read/write access.
Setting up and enforcing address security
If the Security parameter is set to No (its default value), any SNMP manager that presents the
right community name will be allowed access. If you set this parameter to Yes, the DSL
Terminator checks the source IP address of the SNMP manager and allows access only to those
IP addresses listed in the RD MgrN and WR MgrN parameters, each of which specifies up to
five host addresses.
Resetting and verifying reset
You can use SNMP (sysReset object) to reset a DSL Terminator from an SNMP manager.
After the Reset command is issued, a one-minute time-out (not modifiable) permits the DSL
Terminator to confirm the request before the unit is reset.
Information held in the Ascend Events Group is erased and its values are initialized when the
DSL Terminator is reset by software or by toggling the power off and on. The SNMP object
sysAbsoluteStartupTime is the time in seconds since January 1, 1990, and is not
modified. To determine whether the DSL Terminator has actually reset, you can retrieve
sysAbsoluteStartupTime and compare its value against the previous poll’s value for
Ascend Events Group variables.

Example of SNMP security configuration
The following procedure sets the community strings, enforces address security, and prevents
write access:
1
Open Ethernet > Mod Config > SNMP Options.
2
Set R/W Comm Enable to Yes.
3
Specify the Read Comm and R/W Comm parameter strings.
4
Set Security to Yes.
5
Specify up to five host addresses in the RD MgrN parameters. Leave the WR MgrN
parameters set to zero to prevent write access.
6
Close the Ethernet profile.
Following is an example of a profile configured with the preceding procedure.

WR Mgr2=0.0.0.0
WR Mgr3=0.0.0.0
WR Mgr4=0.0.0.0
WR Mgr5=0.0.0.0
Setting SNMP traps
A trap is a mechanism for reporting system change in real time (for example, reporting an
incoming call to a serial host port). When a trap is generated by some condition, a traps-PDU
(Protocol Data Unit) is sent across the Ethernet to the SNMP manager.
Following are the parameters related to setting SNMP traps (shown with sample settings):

parameter to the community name associated with the SNMP PDU.
The Alarm, Port, and Security fields specify whether the DSL Terminator traps respectively
alarm events, port events, and/or security events, and sends a trap-PDU to the SNMP manager.
The Dest field specifies the destination address for the trap-status report. If DNS or YP/NIS is
supported, the Dest field can contain the hostname of a system running an SNMP manager. If
the DNS or YP/NIS is not supported, the Dest field must contain the host’s address.
Note: To turn off SNMP traps, set Dest to 0.0.0.0 and delete the value for Comm.
Example SNMP trap configuration
The following procedure creates a profile that specifies a community name, all the trap types,
and the host’s IP address in the Dest parameter.
1
Open an SNMP Traps profile and assign it a name.
2
Specify the community name (for example, Ascend).
3
Set the trap types to Yes.
4
Specify the IP address of the host to which the trap-PDUs will be sent.
5
Close the SNMP Traps profile.
Following is an example of a profile configured with this procedure:

Ascend enterprise traps
This section provides a brief summary of the traps generated by alarm, port, and security
events. For more details, see the Ascend Enterprise MIB. To obtain the Ascend MIB, see
“Supported MIBs” on page 7-7.
Alarm events
Alarm events (also called error events) use trap types defined in RFC 1215 and RFC 1315, as
well as an Ascend enterprise trap type. The DSL Terminator provides the following trap types:
Alarm event
Signifies that the DSL Terminator sending the trap
coldStart (RFC-1215 Is reinitializing itself and that the configuration of the SNMP manager
trap-type 0)
or the unit might be altered.
warmStart (RFC1215 trap-type 1)
Is reinitializing itself but neither the configuration of the SNMP
manager nor that of the unit will be altered.
linkDown (RFC-1215 Recognizes a failure in one of the communication links represented in
trap-type 2)
the SNMP manager’s configuration.
linkUp (RFC-1215
trap-type 3)
Recognizes that one of the communication links represented in the
SNMP manager's configuration has come up.
frDLCIStatusChange Recognizes that one of the virtual circuits (to which a DLCI number
(RFC-1315 trap-type has been assigned) has changed state. That is, the link has either been
1)
created or invalidated, or has toggled between the active and inactive
states.
eventTableOverwrite Detects that a new event has overwritten an unread event. This trap is
(ascend trap-type 16) sent only for systems that support Ascend's accounting MIB. Once
sent, new overwrites will not cause another trap to be sent until at least
one table’s worth of new events has occurred.
Port state change events
Port state change event traps are effective on a port-by-port basis for each port pointed to by
ifIndex. The hostPort objects are used to associate a change with ifIndex objects.
The following trap types signify a change in the state of the Ascend Inverse Multiplexer (AIM)
port associated with the passed index.
Trap type
Indicates that the indexed AIM port
portInactive (ascend
trap-type 0)
Has become inactive.
portDualDelay
(ascend trap-type 1)
Is delaying the dialing of a second to avoid overloading devices that
cannot handle two calls in close succession.
portWaitSerial
(ascend trap-type 2)
Detects DTR and is waiting for an HDLC controller to come online.
CTS is off (V.25 bis dialing only).
portHaveSerial
(ascend trap-type 3)
Is waiting for V.25 bis commands. CTS is on.
DSL Terminator Administration Guide

SNMP and Syslog Configuration
Configuring SNMP
Trap type
Indicates that the indexed AIM port
portRinging (ascend
trap-type 4)
Has been notified of an incoming call.
portCollectDigits
(ascend trap-type 5)
Is receiving digits from an RS366 interface (RS-366 dialing only).
portWaiting (ascend
trap-type 6)
Is waiting for connect notification from the WAN after dialing or
answer notification has been issued.
portConnected
(ascend trap-type 7)
Has changed state. This change of state can be from connected to
unconnected or vice versa. If connected to the far end, end-to-end data
can flow but has not yet been enabled.
The following trap report sequence shows that a link is up:
portWaiting (6)
portConnected (7)
portCarrier (8)
The following trap report sequence shows that a link is down:
portConnected (7)
portInactive (0)
portCarrier (ascend
trap-type 8)
Has end-to-end data flow enabled.
portLoopback (ascend Has been placed in local loopback mode.
trap-type 9)
portAcrPending
Has set ACR on the RS366 interface, and is waiting for the host device
(ascend trap-type 10) (RS-366 dialing only).
portDTENotReady
Is waiting for DTE to signal a ready condition when performing X.21
(ascend trap-type 11) dialing.
Security events
Security events are used to notify users of security problems and track access to the unit from
the console. The MIB-II event authenticationError is a security event. The other security
events are Ascend-specific. The include:
Security event
Signifies
authenticationFailure The DSL Terminator sending the trap is the addressee of a protocol
(RFC-1215 trap-type message that is not properly authenticated.
4)
consoleStateChange The console associated with the passed console index has changed
(ascend trap-type 12) state. To read the console’s state, get ConsoleEntry from the
Ascend enterprise MIB.
portUseExceeded
The serial host port’s use exceeds the maximum set by the Max DS0
(ascend trap-type 13) Mins Port parameter associated with the passed index (namely, the
interface number).
systemUseExceeded The serial host port’s use exceeds the maximum set by the Max DS0
(ascend trap-type 14) Mins System parameter associated with the passed index (namely, the
interface number).

Supported MIBs
You can download the most up-to-date version of the Ascend Enterprise MIB by logging in as
anonymous to ftp.ascend.com. (No password is required.) In addition to the Ascend
MIB, the DSL Terminator also supports objects related to Ascend functionality in the
following Internet standard MIBs:
•
MIB-II implementation (RFC 1213)
•
DS1 MIB implementation (RFC 1406)
•
RS232 MIB implementation (RFC-1317)
•
Frame Relay MIB implementation (RFC-1315)
•
DS3 and E3 management MIB implementation (RFC 1407)
•
Bridge MIB implementation (RFC1493)
•
Modem MIB implementation (RFC 1696)
You can download the most recent version of these RFCs by logging in as anonymous to
ftp.ds.internic.net. (No password is required.)
Configuring Syslog
You can configure the DSL Terminator to send messages containing call and system events to
an IP host running a syslog daemon.
To configure Syslog support, you must set parameters specifying the IP address of the host
running the Syslog daemon. In addition, there are optional parameters you can set to customize
the way the DSL Terminator sends its Syslog messages.
The IP host running the Syslog daemon is typically a UNIX host, but can be a Microsoft
Windows workstation or server. If the DSL Terminator is on a different network than the IP
host, you must configure the routers so that the DSL Terminator can successfully communicate
with the IP host.
Note: Do not configure the DSL Terminator to send reports to a IP host that can be reached
only by means of a dial-up connection.
Configuring to send Syslog messages
To configure the DSL Terminator to send messages to a Syslog daemon:
1
Open the Ethernet > Mod Config > Log menu.
2
Set the Syslog parameter to Yes.
3
Set Log Host to the IP address of the host running the syslog daemon.
4
Set Log Port to the port at which the syslog daemon listens for Syslog messages from the
DSL Terminator. The default is 514.
DSL Terminator Administration Guide
7-7
SNMP and Syslog Configuration
LAN security error, Modem x:y
5
Set the Log Facility value to be attached to each Syslog message.
The syslog daemon can receive messages from several devices, and it groups the
messages. If the daemon receives messages from devices that specify the same log facility,
it stores them in the same file.
6
Exit and save the changes.
To configure the syslog daemon on a UNIX host, you need to modify the host’s
/etc/syslog.conf file. This file specifies a specific action the daemon performs when it
receives messages with a particular Log Facility number. For example, if you set Log Facility
to Local5 in the DSL Terminator, and the syslog daemon should store messages from the
DSL Terminator in the file /var/log/DSL Terminator, add the following line to the
/etc/syslog.conf file:
local5.info tab /var/log/DSL Terminator
Note: After making changes to the /etc/syslog.conf file, you must direct the UNIX host to
reread the file.
Syslog message format
DSL Terminator units generate Syslog messages in the following format:
date time router_name ASCEND: message
where:
Field
Description
date
The date the message was logged by the syslog daemon. The DSL
Terminator does not datestamp the Syslog messages.
time
The time the message was logged by the syslog daemon. The DSL
Terminator does not timestamp the syslog messages.
router_name The name of the DSL Terminator sending the message.
message
The specific activity that caused the DSL Terminator to send the Syslog
packet.
Syslog messages and their meanings
Syslog messages are recorded during establishment of a connection, during graceful or
unexpected disconnection and during various other events.
In a Syslog message, slot x port y indicates that action occurred in a session with the
module (slot card) located in slot x. Because slot cards support multiple simultaneous sessions,
the DSL Terminator assigns the session to a specific port. For digital connections, port
typically indicates an HDLC channel on an Ethernet card or Ether-Data card, although port can
indicate a port on a slot card supporting inverse multiplexing.
LAN security error, Modem x:y—The DSL Terminator received a call on modem y in
the module in slot x. The call has failed either because authentication failed, or because the IP
address of the user did not match the IP address configured in the user’s profile.
7-8
DSL Terminator Administration Guide
SNMP and Syslog Configuration
No connection
No connection—There was no response from the far end unit when the DSL Terminator
attempted to connect.
No Channel Avail—All channels on the DSL Terminator are either supporting active
connections or are disabled.
No Chan Other End—The unit that DSL Terminator is attempting to connect with did not
have an available channel on which to answer the call.
Network Problem—The network has reported a protocol error.
Far End Hung Up—The network notified the DSL Terminator that the calling unit has
disconnected the call.
Remote Mgmt Denied—A user attempted to initiate a remote management session, which
was denied by the far end unit.
Incoming Net-2-Net—The DSL Terminator received an incoming Net-2-Net call.
Sys user exceeded—The DSL Terminator dropped the call because the call had exceeded
the configured maximum system DS0 minutes.
Port use exceeded—The DSL Terminator dropped the call because the call had exceeded
the maximum port DS0 minutes specified in the Port profile.
High Bit Errors—During a Bit Error Rate Test (BERT), the DSL Terminator detected a high
number of bit errors.
Normal Bit Errors—During a Bit Error Rate Test (BERT), the DSL Terminator detected a
normal number of bit errors.
No Trunk Available—The DSL Terminator has no active WAN links.
Trunk Down—A WAN link has gone down.
Trunk Up—A WAN link has become active.
Ethernet Up—The Ethernet interface of the DSL Terminator has become active or been re
initialized. This message is logged when the Ethernet interface first comes up, or on the basis
of a change to the Ethernet interface.
IP address 0.0.0.0 not valid for login service—A user attempted to initiate a login
service with an invalid IP address.
TACACS+:No more TCP sockets—The DSL Terminator could not initiate a TACACS+
session.
TACACS+:Unexpected TCP close event. Server down?—The DSL Terminator
received a TCP Close packet before the TACACS+ TCP session was established.
TACACS+:Resource shortage—The DSL Terminator experienced a low memory
condition while processing TACACS+ session.
DSL Terminator Administration Guide
7-9
SNMP and Syslog Configuration
TACACS+:Shutdown in read
TACACS+:Shutdown in read—The DSL Terminator experienced an unexpected end to a
TACACS+ session.
TACACS+:Server timeout—The DSL Terminator timed out while waiting to connect to the
TACACS+ server.
TACACS+:Table exhausted—The DSL Terminator has no available entries in its
TACACS+ entry table.
TACACS+:Illegal server response—The DSL Terminator received an illegal response
from the TACACS+ server.
Backoff Q full, discarding user 10.10.10.1[250725066]—Backoff-queue overflow has
resulted in silent discarding of the oldest entry. When a RADIUS accounting event occurs, the
DSL Terminator (the NAS) sends an Accounting-Request message to the RADIUS
Accounting server, which sends back an Accounting-Response message to acknowledge
receipt. The NAS is required to buffer the event until it receives an acknowledgment. The
NAS employs a simple exponential backoff algorithm between reattempts. The backoff
algorithm is:
backoff_time = 3 * backoff_time
where backoff_time = [1..N]
Once the NAS sends an accounting request, if no response is received from the Accounting
server, the NAS enters backoff mode.
If the backoff queue is not empty when an accounting event occurs (a new user logs in or an
existing user logs out), the event goes directly onto the backoff queue.
A maximum of 100 entries is allowed on the backoff queue. If the queue overflows. the oldest
entry is silently discarded, and the DSL Terminator sends the Syslog message.
The backoff queue can be cleared by setting Acct = None on the DSL Terminator or by
resetting the DSL Terminator.
When you see this Syslog message, your Accounting Server is not functioning properly. If
Acct = RADIUS on the DSL Terminator, verify that you are using the correct Port number
(e.g. 1646) and that the Acct Key matches the password in the clients file on the RADIUS
server. Also, be aware that the default location for your accounting records is
/usr/adm/radacct. You have to create the radacct directory. RADIUS will
automatically create a subdirectory with the name or IP address of the DSL Terminator
(depending on your entry in the clients file) and will then write to the detail file. You can
redirect your accounting output by starting RADIUS with the -a option (for example,
radiusd -a /usr/adm/ascendlog).
Disconnect codes and progress codes

Common problems and their solutions
General problems
When the list of DO commands appears, many operations might not be not available if the
right profile has not been selected. Because the DSL Terminator can manage a number of calls
simultaneously, you might need to select a specific Connection profile, Port profile, or Call
profile in order to see certain DO commands. For example, to dial from a Call profile or a
Connection profile, you must move to the Call profile (Host/6 > Port N Menu > Directory) or
the Connection profile and press Ctrl-D 1.
Note that you cannot dial if Operations=No for the control port. If a call is already active,
DO 2 (Hang Up) appears instead of DO 1 (Dial). If the T1 or E1 line is not available, Trunk
Down appears in the message log and you cannot dial.
Configuration problems
The most common problems result from improperly configured profiles.
The DSL Terminator cannot dial out on a T1 or E1 line
To verify that the configured profile is correctly configured:
1
Make certain that you have entered the correct phone number to dial.
2
Verify that the Data Svc parameter specifies a WAN service available on your line.
If you request a WAN service that is not available on your line, the WAN rejects your
request to place a call.
3
Check whether the channels using the requested WAN service are busy.
If these channels are busy, an outgoing call might be routed to channels for which you did
not request the specified WAN service. Check the Data Svc, Call-by-Call, and PRI # Type
parameter values in the profile.
4
Determine whether you have correctly set the parameters controlling Dynamic Bandwidth
Allocation.
For detailed information, see the Network Configuration Guide for your DSL Terminator.
Restored configuration has incorrect RADIUS parameters
On earlier RADIUS Servers, the submenu consisted of three clients (specific host addresses)
and one Server Key for all three clients. If the DSL Terminator supports the new RADIUS
Server, the restoration of the DSL Terminator configuration will cause a problem, because the
new RADIUS Server allows up to nine addresses (host or net) and a Server Key for each
address. When you restore configurations with the old Client Address list, the subnet mask
assigned to the clients will be the default subnet mask of the address type given (for example,
128.50.1.1 will get a subnet mask of 16) and not the previous 32-bit (single host) address. In
addition, the Server Key will not automatically be set. You must set the Server Key manually
for each client in the RADIUS Server submenu.
Hardware configuration problems
If you cannot communicate with the DSL Terminator through the VT100 control terminal, you
might have a problem with terminal configuration, the control port cable, or the DSL
Terminator hardware.

DSL Terminator Administration Guide
Troubleshooting
Common problems and their solutions
Cannot access the VT100 interface
If no data is displayed on the VT100 interface, verify that the unit completes all of the
Power-On Self Tests (POST).
For information, see the Hardware Installation Guide for your DSL Terminator.
Random characters appear in the VT100 interface
If random or illegible characters appear on your display, you probably have a communications
settings problem. Specify the following settings:
•
9600 bps data rate
•
8 data bits
•
1 stop bit
•
No flow control
•
No parity
If you have changed the data rate through the Port profile, make certain that your VT100
terminal matches that rate.
A Power-On Self Test fails
If the start-up display indicates a failure in any part of the POST, an internal hardware failure
has occurred with the unit. In this case, contact Lucent Customer Service.
Bridge/router problems
Problems with a bridge or router can include the uncertainty of link quality and the DSL
Terminator hanging up after answering an IP call.
The link is of uncertain quality
When running File Transfer Protocol (FTP), the data transfer rate appears in bytes per second.
Multiply this rate times 8 to get the bits per second. For example, suppose that you are
connected to Detroit on a 56-Kbps B channel and that FTP indicates a 5.8 Kbyte/s data rate. In
this case, the link is running at 5.8x8=46.8 Kbps, or approximately 83% efficiency. Many
factors can affect efficiency, including the load on the FTP server, the round-trip delay, the
overall traffic between endpoints, and the link quality.
You can check link quality in the WAN Stat status window, or by running a Ping between the
same endpoints. Dropped packets hurt the link’s efficiency, as does round-trip delay. Random
round-trip delay indicates heavy traffic, a condition that also drops the efficiency of the link.
The DSL Terminator hangs up after answering an IP call
If the DSL Terminator hangs up after answering an IP call, proceed as follows:
1
If you are running PPP, verify that you have entered the proper passwords.
2
Verify that Auth is set to PAP or CHAP.
3
If you are routing IP over PPP, verify that the calling device gives its IP address
DSL Terminator Administration Guide
A-5
Troubleshooting
Common problems and their solutions
Some calling devices supply their names, but not their IP addresses. However, you can
derive an IP address if the calling device is listed in a local Connection profile or on a
RADIUS authentication server. Try enabling PAP or CHAP for the Recv Auth parameter
so that the DSL Terminator matches the caller’s name to the Station parameter in a
Connection profile and gets the corresponding LAN Adrs.

The diagnostic commands usually provide information about the unit, the interface or its
connections. This information can help you determine where the problems are. Under most
circumstances, diagnostic commands are not required for correct operation of the DSL
Terminator. In some circumstances, using these commands might produce undesirable results.
All available information about the DSL Terminator diagnostic commands is listed here. It is
organized alphabetically for quick reference, and does not include tutorials. Use the following
information with caution. Contact Lucent Technical Support with any questions or concerns.
This guide provides
Note: Every attempt has been made to confirm that this chapter correctly describes the
functionality and output of the DSL Terminator diagnostic commands. But while diagnostic
mode can be a very valuable troubleshooting tool for anyone, its primary focus is on the
requirements of Lucent’s development engineers. For this reason, Lucent does not guarantee
the completeness of the list of commands or of the cataloging of functionality from release to
release.
Using diagnostic commands
To be allowed access to diagnostic mode, you must set the Field Service privilege to Yes in
the active Security profile.
Use one of the following two methods to access diagnostic mode:
•
From the DSL Terminator VT100 interface, display the DO menu by pressing Ctrl-D.
Then press D or select D=Diagnostics.
•
From the DSL Terminator VT100 interface, type the following key sequence in rapid
succession:
Esc [ Esc =
(Press the Escape key, followed by the Left Bracket key, then the Escape key again,
followed by the = key.)
You must press all four keys within one second for the DSL Terminator to recognize the
escape sequence.

Command reference
To display an abbreviated list of the most commonly used commands in diagnostic mode, enter
a question mark:
>?
To display a complete listing, append ascend to the question mark:
>? ascend
To exit diagnostic mode, enter quit.
Because most diagnostic commands are designed to give a developer information about
specific aspects of DSL Terminator functionality, you might find it helpful to use commands in
combination to troubleshoot different problems.
For example, when troubleshooting modem-related issues, you might want to use
ModemDrvState, ModemDiag, and MDialout (if modem dial-out is supported on your DSL
Terminator) to get all modem-related information for your calls.
Using several commands simultaneously not only gives you a clearer picture of what is
happening, but also shows you a chronological timeline of the events.

Description
Unnamed first column indicates how the address was learned,
dynamically (DYN) or by specification of a Bridge Address (STA).
ip address
Network address contained in ARP requests.
ether addr
Media Access Control (MAC) address of the host identified by ip
address. Also referred to as the hardware address.

rts
Routes pointing to the address.
pkt
Number of packets queued.
ref
Number of times that the address was used.
insert
Time at which this entry was inserted into the ARP table.
Callback
Description: Displays messages related to the callback functionality of the DSL Terminator.
You can use the command to display, for example, sessions queued for callback. The command
is a toggle that alternately enables and disables the debug display.
With the callback feature enabled, the DSL Terminator hangs up after receiving an incoming
call that matches the specifications in the Connection profile. The DSL Terminator then uses
the Dial # parameter specified in the Connection profile to call back the device at the remote
end of the link.
You can use the callback command to tighten security by ensuring that the DSL Terminator
connects to known destinations only. The command can also help you troubleshoot detailed
areas of the callback process.
Usage: callback
Example: Following are several examples of output displayed by the Callback command.
> callback
CALLBACK debug is now ON
The following message appears as the DSL Terminator prepares to call back the remote end:
CALLBACK: processing entry topeka
The DSL Terminator then dials the remote end:
CALLBACK: initiate call to topeka
When the call has been made and is being negotiated:
CALLBACK: new state WAITING
If callback failed and will be retried:
CALLBACK: new state FAILED
B-4
DSL Terminator Administration Guide
Diagnostic Command Reference
Clr-History
If callback is never successful, the call is marked for removal from the callback list and the
following message appears:
CALLBACK-FAILED: topeka marked as failed
After the remote end is called back, its entry is removed from the Callback list so that the DSL
Terminator can reallocate and use the resources. The following message appears:
CALLBACK: deleting entry topeka
To terminate the display:
> callback
CALLBACK debug is now OFF
Clr-History
Description: Clears the fatal-error history log.
Usage: clr-history
To display the log before clearing it, enter the Fatal-History command.

Ether-Display
Description: Displays the contents of Ethernet packets.
If you enter the command while traffic through your DSL Terminator is heavy, the resulting
amount of output can make it tedious to find the information you are looking for. The screen
might even display the message ----- data lost -----, which just means that not all
the output can be displayed on the screen. You might prefer to use the Ether-Display command
during a period of low activity.

ETHER message display terminated
Fatal-History
Description: Displays the fatal-error log. Each time the DSL Terminator reboots, it logs a
fatal-error message to the fatal-error history log. The fatal-error log also includes Warnings, for
which the DSL Terminator did not reset. Development engineers use Warnings for
troubleshooting purposes. A Warning indicates that the DSL Terminator detected an error
condition but recovered from it. The number of entries in this log is limited by available flash
space, and the errors rotate on a First-In, First-Out (FIFO) basis. You can use the Clr-History
command to clear the log.
Note: If your DSL Terminator experiences a fatal-error reset or Warning, contact Lucent
Technical Support immediately.

FClear
FClear
Description: Clears Flash memory on the DSL Terminator. When the DSL Terminator boots,
it loads the code and configuration from Flash memory into Dynamic Random Access
Memory (DRAM). If you want to return your DSL Terminator to its factory-set defaults, you
need to perform an FClear.
Usage: fclear
Example:
> fclear
FRestore
Description: Restores a configuration from Flash memory and loads it into DRAM on the
DSL Terminator.
Note: The DSL Terminator performs an FRestore when it boots. You need to execute the
command if you have made changes to the current configuration and want to restore the
configuration stored in Flash memory.
Usage: frestore
FSave
Description: Stores the current configuration into Flash memory.
Note: When you load code with the TloadCode command, an FSave is performed
automatically before the code is uploaded. When the box boots after the upload, the DSL
Terminator will load the configuration stored in Flash rather than be reset to factory default
settings.
Usage: fsave .

NSLookup
Description: Similar to the UNIX nslookup command. When you specify a host name, a DNS
request is forwarded. If the host is found, the corresponding IP address is displayed.
Usage: nslookup host_name
DSL Terminator Administration Guide
B-11
Diagnostic Command Reference
NVRAMClear
Example:
> nslookup host1
Resolving host host1.
IP address for host drawbridge is 1.1.1.1.
> nslookup 198.4.92.1
Resolving host 198.4.92.1.
> nslookup
Missing host name.
> nslookup nohost
Resolving host nohost.
Unable to resolve nohost!
NVRAMClear
Description: Clears Nonvolatile Random Access Memory (NVRAM). The current system
configuration is stored in NVRAM.
Note: A copy of the configuration may also be stored in Flash memory. If you clear NVRAM,
the DSL Terminator resets and initializes itself with the configuration it detects in Flash
memory. To return your DSL Terminator to its factory default settings, you must first use the
FClear command to clear the configuration in Flash then use NVRAMClear.
Usage: nvramclear .
See Also: FClear
PPPDump
Description: Very similar to the WANDisplay diagnostic command. But PPPDump strips out
escape characters that are present for asynchronous PPP users (who are dialing in with
modems). The escape characters are necessary because of the asynchronous nature of the data
stream. Stripping them out simply clarifies the presentation of the data.
If you enter the command while traffic through your DSL Terminator is heavy, the resulting
amount of output can make it tedious to find the information you are looking for. The screen
might even display the message ----- data lost -----, which just means that not all
the output can be displayed on the screen. You might prefer to use the PPPDump command
during a period of low throughput.
Usage: pppdump n
where n is the number of octets to display per frame. Specifying a value of 0 (zero) disables
the logging of data.
Example:
Consider the following frames, which were logged by the WANDisplay 64 command:
7E

DSL Terminator Administration Guide
Diagnostic Command Reference
PPPFSM
To get the data stream without escape characters, the 0x7D bytes need to be stripped, and the
byte following each 0x7D byte needs to be decremented by 0x20.
With PPPDump, the DSL Terminator automatically convert and displays the data as follows:
7E FF 03 C0 21 01 01 00 17 02 06 00 0A 00 00 2D 03 06 3A AA 7E 7E

See Also: WANDisplay, WANNext, WANOpen
PPPFSM
Displays changes to the PPP state machine as PPP users connect. The command is a toggle that
alternately enables and disables the diagnostics display.
Usage: pppfsm .
Example: The following display shows the complete establishment of a PPP session.
> pppfsm

RadAcct
Description: Displays RADIUS accounting information. The RadAcct command displays
very few messages if RADIUS Accounting is functioning correctly. The command is a toggle
that alternately enables and disables the diagnostic display.
(For troubleshooting RADIUS-related issues, the RADIF command displays more detailed
information.)
Usage: radacct .
Example:
> radacct
RADACCT debug display is ON
A user hangs up and a stop record is generated:
RADACCT-147:stopRadAcct
The following message indicates that there is some load on the network and the sending of a
stop record is delayed. This does not necessarily indicate a problem:
RADACCT-147:_endRadAcct: STOP was delayed
RadIF
Description: Displays RADIUS-related messages. RadIF is a powerful diagnostic command,
because it displays RADIUS messages the DSL Terminator receives as well as messages that it
sends. Output from RadIF, in conjunction with running your RADIUS daemon in diagnostic
mode (using the -x option), gives you virtually all the information you need to clarify issues
relating to user authentication.
B-16
DSL Terminator Administration Guide
Diagnostic Command Reference
RadIF
You can also validate the IP port that you have configured (or think you have configured), and
the user name that is being sent by the client.
The command is a toggle that alternately enables and disables the diagnostic display.
Usage: radif .
Example: Following are messages you might see for a successful RADIUS authentication:
RADIF: authenticating <8:my_name> with PAP
RADIF: _radiusRequest: id 41, user name <9:my_name>
RADIF: _radiusRequest: challenge len = <0>
The RADIUS daemon IP address and authentication port appear:
RADIF: _radiusRequest: socket 5 len 89 ipaddr 01010101 port
65534->1645
RADIF: _radCallback
RADIF: _radCallback, buf = B05BBFA0
The response is sent back from RADIUS. In this case, the user my_name has passed
authentication. Following is a list of the most common responses:
1 - Authentication Request
2 - Positive Acknowledgement
3 - Rejection
4 - Accounting Request
5 - Accounting Response
7 - Password Change Request
8 - Password Change Positive Acknowledgement
9 - Password Change Rejection
11 - Access Challenge
29 - Password - next code
30 - Password New PIN
31 - Password Terminate Session
32 - Password Expired
RADIF: _radCallback, authcode = 2
RADIF: Authentication Ack
After authenticating a user, the RADIUS daemon sends the attributes from the user profile to
the DSL Terminator. The DSL Terminator creates the user’s Connection profile from these
attributes, and RadIF displays them. For a complete list of attribute numbers, see the TAOS
RADIUS Guide and Reference.

Reset
Description: Resets the DSL Terminator, which terminates all active connections and restarts.
All users are logged out and the default security level is reactivated. All active WAN lines are
temporarily shut down because of the loss of signaling or framing information. As the DSL
Terminator boots, it runs its Power-On Self Tests (POST).
Usage: reset .
Example: To reset the unit:
> reset
See Also: NVRAM
TRestore
Description: Restores a saved configuration from a TFTP host to Flash memory on the DSL
Terminator. You need to manually reboot the DSL Terminator to load the restored
configuration from Flash memory into dynamic RAM.
Usage: trestore name_or_ip_address_of_tftp_server filename
Example:
> trestore 1.1.1.1 config.txt
restoring configuration from 1.1.1.1:69
file config.txt...
TSave
Description: Saves the DSL Terminator configuration that is stored in flash memory to a
TFTP server. You need to perform the FSave command if you want to save your currently
running configuration. FSave saves the currently running configuration to flash memory.
Usage: tsave name_or_ip_address_of_tftp_server filename
Example:
B-18
DSL Terminator Administration Guide
Diagnostic Command Reference
Update
> tsave 1.1.1.1 config.txt
saving configuration to 1.1.1.1:69
file config.txt...
Update
Description: Modifies optional functionality of the DSL Terminator. To enable some options,
you must obtain a set of hash codes (supplied by an Lucent representative) that will enable the
functionality in your DSL Terminator. After each string is entered, the word complete appears,
indicating that the DSL Terminator accepted the hash code.
If you enter the update command without a text string modifier, the DSL Terminator displays a
list of current configuration information.
Usage: update [text_string]
Example:
> update
Host interfaces: 4
Net interfaces: 4
Port 1 channels: 255
Port 2 channels: 255
Port 3 channels: 255
Port 4 channels: 255
Field features 1: 182
Field features 2: 33
Field features 3: 54
Protocols: 1
> update 5 1023 12321312312312321
The following two messages indicate that the text strings were entered incorrectly:
update command: invalid arg 3!
update command: disallowed
The following message indicates that the DSL Terminator accepted the update string:
update command: command complete.
WANDisplay
Description: Displays all packets received from or sent to any of the WAN interfaces.
Because WANDisplay ouput shows the raw data the DSL Terminator is receiving from and
sending to the remote device, the information can be very helpful in PPP negotiation problems.
If you enter the command while traffic through your DSL Terminator is heavy, the resulting
amount of output can make it tedious to find the information you are looking for. The screen
might even display the message ----- data lost -----, which just means that not all
the output can be displayed on the screen.
You might prefer to use the WANDisplay command during a period of low activity.
Alternatively, depending on the types of information you need to gather, you might use
WANDSess, WANOpen, or WANNext to focus the display.
DSL Terminator Administration Guide

WANDSess
Usage: wandisplay number_of_octets_to display_from_each_packet
Enter wandisplay 0 to disable the logging of this information.
Example: Following are several examples of WANDisplay output. Note that the bytes are
displayed in hexadecimal format.

WAN message display terminated
See Also: WANDSess, WANOpening, WANNext
WANDSess
Description: Similar to WANDisplay, but WANDSess displays only incoming and outgoing
packets for a specific user. WANDSess is particularly helpful for troubleshooting a DSL
Terminator with several simultaneous active connections. The volume of output from
commands such as WANDisplay make them not as effective for troubleshooting issues for
particular users. WANDSess is a filter to let you focus your troubleshooting.
Even though WANDSess does act as a filter, if you enter the command while traffic through
your DSL Terminator is heavy, the resulting amount of output can make it tedious to find the
information you are looking for. The screen might even display the message ----- data
lost -----, which just means that not all the output can be displayed on the screen. You
might prefer to use the WANDSess command during a period of low activity.
Usage: wandsess user_name_or_profile_name number_of
octets_to_display_from each_packet
Enter wandsess user_name_or_profile_name 0 to disable the logging of this
information.
Example:
> wandsess gzoller 24
RECV-gzoller:300:: 1 octets @ 3E13403C
[0000]: 7E 21 45 00 00 3E 15 00 00 00 20 7D 31 C2 D2
RECV-gzoller:300:: 15 octets @ 3E133A24
[0000]: D0 7D B3 7D B1 B3 D0 7D B3 90 02 04 03 00 35
XMIT-gzoller:300:: 84 octets @ 3E12D28C
[0000]: 7E 21 45 00 00 4E C4 63 00 00 1C 7D 31 17 5F D0
[0010]: 93 90 02 D0 93 91 B3 00
Notice that thedifference in output between WANDSess and WANDisplay is that WANDSess
limtis the output to one session and the name of the user is displayed in a message. The data is
identical in content, but WANDSess displays no data from any other sessions.
B-20
DSL Terminator Administration Guide
Diagnostic Command Reference
WANNext
> wandsess gzoller 0
See Also: WANDisplay, WANNext, WANOpening
WANNext
Description: Similar to WANDisplay, but WANNext displays only incoming and outgoing
packets for the next successfully authenticated user. As with WANDSess, the output is the
same as for WANDisplay but is filtered to include only data from a single user.
Even though WANNext asct as an output filter, if you enter the command while traffic through
your DSL Terminator is heavy, the resulting amount of output can make it tedious to find the
information you are looking for. The screen might even display the message ----- data
lost -----, which just means that not all the output can be displayed on the screen. You
might prefer to use the WANNext command during a period of low activity.
Usage: wannext number_of_octets_to_display_from_each_packet
Enter WANNext 0 to disable the logging of this information.
WANOpening
Description: Similar to WANDisplay, but WANOpening displays only the opening incoming
and outgoing packets for all users during the establishment of their PPP sessions. This
command is particularly helpful if you are troubleshooting connection problems in which users
seem to connect to the DSL Terminator but are disconnected within a few seconds. Again, the
output from WANOpening is very similar to WANDisplay but WANOpening displays packets
for sessions only until the connection has been completely negotiated.
Even though WANOpening limits the output seen on the screen, if you enter the command
while traffic through your DSL Terminator is heavy, the resulting amount of output can make it
tedious to find the information you are looking for. The screen might even display the message
----- data lost -----, which just means that not all the output can be displayed on
the screen. You might prefer to use the WANOpening command during a period of low
activity.
Usage: wanopening number_of_octets_to_display_from_each_packet
Enter WANOpening 0 to disable the logging of this information.
WANToggle
Description: Displays messages from the WAN drivers on the DSL Terminator, including the
state of calls that have been processed by the DSL Terminator’s calling routines but not yet
sent to the Ethernet drivers.
If you enter the command while traffic through your DSL Terminator is heavy, the resulting
amount of output can make it tedious to find the information you are looking for. The screen
might even display the message ----- data lost -----, which just means that not all
the output can be displayed on the screen. You might prefer to use the WANToggle command
during a period of low activity.
DSL Terminator Administration Guide
B-21
Diagnostic Command Reference
WDDialout
The command is a toggle that alternately enables and disables the diagnostic display.
Usage: wantoggle .
Example: Typical output produced by a modem call into the DSL Terminator is similar to that
found below. After the incoming call is determined to be an analog call, a modem is directed to
answer it.
WAN-389:
WAN-389:
WAN-389:
WAN-389:
WAN-389:
WAN-389:
wanOpenAnswer

wanRegisterData, I/F 58
The next two messages appear when the call is cleared. The second message does not indicate
a problem. It appears because the modem clears the call a split second before the software
releases its resources. The software does a check on the modem, which has already been
released.
WAN-389: wanCloseSession, I/F 58
WAN-??: no modem assoc w WanInfo
WDDialout
Description: Displays the specific packet that caused the DSL Terminator to dial out. The
command is particularly helpful if the DSL Terminator is dialing out when it should not. You
can use WDDialout information to design a filter to keep the DSL Terminator from dialing out
because of a particular packet.
The command is a toggle that alternately enables and disables the diagnostic display.
Usage: wddialout .
Example: The following message includes a date/time stamp, the phone number being dialed,
and the packet that caused the DSL Terminator to dial out:
Date: 01/01/1990.
Time: 00:51:56
Cause an attempt to place call to 18185551234

PPP decoding primer
Many of the diagnostic commands display raw data. This section to assists you in decoding
PPP, MP, MP+ and BACP negotiations. The negotiations can be logged with the PPPDump,
B-22
DSL Terminator Administration Guide
Diagnostic Command Reference
PPP decoding primer
WANDisplay, WANDSess, WANNext, or WANOpen diagnostic commands. For more detailed
information than this appendix provides, see specific RFCs. A partial list of pertinent RFCs
appears at the end of this appendix.
Breaking down the raw data
An important concept to keep in mind is that each device negotiates PPP independently, so the
options might be identical for each direction of the session. During PPP negotiation, frame
formats in the various protocols are very similar. They share the following characteristics:
•
FF 03 which indicates a PPP frame
•
A two-byte Protocol Identifier
•
A one-byte Packet Format ID number
•
A one-byte ID number
•
A two-byte length
•
Options for the protocol
Following are the most common protocols you will see in Lucent diagnostic traces:

Annotated Traces
Following are sample traces you can use as guides to help you decode other traces.
Example of a PPP connection attempt
LCP Configure Request—MP+, MRU of 1524, MRRU of 1524 and End Point Discriminator
using the device’s MAC address:
XMIT-3:: 29 octets @ 2C2E94
[0000]: ff 03 c0 21 01 01 00 19 00 04 00 00 01 04 05 f4
[0010]: 11 04 05 f4 13 09 03 00 c0 7b 4c e0 4c
Following is a second LCP Configure Request from the same device. Everything in the packet
is identical to the previous packet, except the ID number has incremented from 01 to 02:
XMIT-3:: 29 octets @ 2C2E94
[0000]: ff 03 c0 21 01 02 00 19 00 04 00 00 01 04 05 f4
[0010]: 11 04 05 f4 13 09 03 00 c0 7b 4c e0 4c

[0010]: 36 c9 05
LCP Configure Acknowledgment—The device in the following trace will be authenticated
with CHAP. The Magic number is also acknowledged:

XMIT-3:: 19 octets @ 2C2E94
[0000]: ff 03 c0 21 02 60 00 0f 03 05 c2 23 05 05 06 4e
[0010]: 36 c9 05
LCP Configure Reject—MP+, MRU of 1524, MRRU of 1524 and End Point Discriminator.
This rejection shows two things. First, the remote side does not support MP+ or MP, since
MP+ and the MRRU were rejected. This will have to be a PPP connection. Second, since the
MRU of 1524 was rejected, the default of 1500 is assumed. There must be an MRU, so a
rejection of a given value only calls for use of the default value.
After the trace, the device will need to transmit another LCP Configure Request, removing all
the rejected options:
RECV-3:: 29 octets @ 2BF1A4
[0000]: ff 03 c0 21 04 02 00 19 00 04 00 00 01 04 05 f4
[0010]: 11 04 05 f4 13 09 03 00 c0 7b 4c e0 4c
LCP Configure Request—Note that all values that were previously rejected are no longer in
the packet:
XMIT-3:: 8 octets @ 2C2E94

At this point, since both sides have transmitted LCP Configure Acknowledgments, LCP is up
and the negotiation moves to the authentication phase. The device receives a CHAP challenge
from the remote end:

The remote device sends a CHAP Acknowledgment:
RECV-3:: 8 octets @ 2C03EC
[0000]: ff 03 c2 23 03 01 00 04
At this point, the negotiation moves from authentication to negotiation of Network Control
Protocols (NCPs). Lucent supports Bridging Control Protocol (BCP), IPCP, and ATCP.

At this point, LCP is up. Next is the authentication phase. The local device agreed to PAP
authentication, so it should transmit its user name and password. Note that they are not
encrypted and can be decoded very easily.

Authentication is successful. Final negotiation determines protocols to be supported over the
link.
Note: MP+ was negotiated, and both devices begin sending MP+ packets from this point. The
data portion of the packet is identical to PPP, but there is an eight-byte MP+ header instead of
the two-byte PPP header:

This appendix explains how to change your system software by either upgrading or
downgrading it. Before you upgrade or downgrade your software, review the related terms and
definitions in the following list and review the guidelines for upgrading and downgrading in
the sections “Guidelines for upgrading system software” on page C-1 and “Downgrading
system software” on page C-7
For the names of all the software builds and the features they provide, see
fttp://ftp.ascend.com/pub/Software-Releases/Terminator/ on the
FTP server. .
Guidelines for upgrading system software
!
Caution: Before upgrading, consider the following very important guidelines:
•
Use TFTP to upgrade if possible. TFTP is more reliable and saves the DSL Terminator unit
configuration when you upgrade.
•
If you are using TFTP to upgrade your software, use the fsave command immediately
after executing the tload command. Failure to do so might cause your DSL Terminator
to lose its configuration.
•
If possible, always stay with the same build of software when you upgrade. If you load a
different version, your DSL Terminator may lose its configuration. If this happens, you
must restore your configuration from a backup.
DSL Terminator Administration Guide
C-1
Upgrading System Software
Preparing to upgrade your software
Preparing to upgrade your software
Make sure you perform all the tasks explained in Table C-1 before upgrading your software.
Table C-1. Before upgrading
Task
Description
If necessary, activate a Security
Profile that allows for field upgrade.
If you are not sure how, see the section about Security Profiles in your
documentation.
Record all of the passwords you want
to retain, and save your unit’s current
configuration to your computer’s hard
disk.
For security reasons, passwords are not written to configuration files
created through the serial console. A configuration file created using the
Tsave command, however, does contain the system passwords. You can
restore the Tsave configuration file using the serial console. If you
chose to save your configuration using the serial console, you have to
restore your passwords manually. Restoring passwords is explained in
“Restoring passwords” on page C-6.
Obtain the correct file, either by
downloading it from the FTP server or
by requesting it from Lucent technical
support.
To ensure that you load the correct software binary, check the load
currently installed on your unit. To do so:
1
Tab over to the 00-100 Sys Options window.
2
Press Enter to open the Sys Options menu.
3
Using the Down-Arrow key (or Ctrl- N), scroll down until you see a
line similar to the following:
Load: tl.dm2
4
When upgrading, obtain the file with same name from the Ascend
FTP site.
If your unit does not display the current load or you are unsure about
which load to use, contact technical support.
If you are using TFTP, make sure you
load the correct binaries into the TFTP
home directory on the TFTP server.
TFTP is the preferred method of upgrading your unit.
If you are using the serial port, make
sure you have a reliable terminal
emulation program, such as Procomm
Plus.
Upgrading through the serial port is generally not recommended.
If you use a Windows-based terminal emulator such as Windows
Terminal or HyperTerminal, disable any screen savers or other programs
or applications that could interrupt the file transfer. Failure to do so
might cause the software upload to halt, and can render the DSL
Terminator unusable.
Upgrading system software
To upgrade system software with a standard load you can use either the serial port or TFTP.
TFTP is the recommended method because it preserves your DSL Terminator unit’s
configuration. If you want to use the serial port to upgrade, see “Using the serial port to
upgrade” on page C-3.
C-2
DSL Terminator Administration Guide
Upgrading System Software
Upgrading system software
Using TFTP to upgrade
To upgrade using TFTP, you must enter a few commands in the correct sequence. If you do not
enter them in the correct sequence, you could lose the DSL Terminator unit’s configuration.
1
Obtain the software version you want to upgrade to and place it in the TFTP server home
directory.
2
From the DSL Terminator unit’s VT100 interface, access the diagnostics monitor by
typing the following characters in rapid succession:
Esc [ Esc =
Or, press Ctrl-D to invoke the DO menu and select D=Diagnostics.
3
At the > prompt, use the Tsave command to save your configuration. For example, the
following command restores the configuration named router1.cfg from the TFTP
home directory of the server named tftp-server. The file must exist and be readable.
> tsave -a tftp-server router1.cfg
Normally, TFTP upgrades save the configuration. Tsave is a precaution.
Caution: The file you save with the Tsave command contains all the passwords in
clear text. You should move this file from the TFTP directory to a secure location after the
upgrade procedure is complete.
!
4
Enter the following command:
tloadcode hostname filename
replace hostname with the name or IP address of your TFTP server, and filename
with the name of the system software on the server (relative to the TFTP home directory).
For example, the following command loads t.m40 into flash from the machine named
tftp-server:
tloadcode tftp-server tl.dm2
Caution: You must use the Fsave command immediately after executing the Tload
command. Failure to do so can cause your DSL Terminator to lose its configuration.
!
5
Enter the following command to save your configuration to flash memory:
6
Enter the following command:
> fsave
> nvramclear
After the DSL Terminator clears NVRAM memory, it automatically resets.
This completes the upgrade.
Using the serial port to upgrade
!
Caution: Uploading system software via the serial console overwrites all existing profiles.
Save your current profiles settings to your hard disk before you begin upgrading system
software. After the upgrade, restore your profiles from the backup file you created. The backup
file is readable text, so you can reenter the settings through the DSL Terminator unit’s user
interface. To avoid having existing profiles overwritten, use TFTP to upgrade your unit.
DSL Terminator Administration Guide
C-3
Upgrading System Software
Upgrading system software
Upgrading through the serial port consists of the following general steps:
•
Saving your configuration
•
Uploading the software
•
Restoring the configuration
Before you begin
Before upgrading your system through the serial port, make sure you have the following
equipment and software:
!
•
An IBM compatible PC or Macintosh with a serial port capable of connecting to the DSL
Terminator unit’s Console port.
•
A straight-through serial cable.
•
Data communications software for your PC or Mac with XModem CRC/1K support (for
example, Procomm Plus, HyperTerminal for PCs, or ZTerm for the Mac).
Caution: If you use a Windows-based terminal emulator such as Windows Terminal or
HyperTerminal, disable any screen savers or other programs or applications that could
interrupt the file transfer. Failure to do so might cause the software upload to halt, and can
render the DSL Terminator unusable.
Saving your configuration
Before you start, verify that your terminal emulation program has a disk capture feature. Disk
capture allows your emulator to capture to disk the ASCII characters it receives at its serial
port. You must also verify that the data rate of your terminal emulation program is set to the
same rate as the Term Rate parameter in the System Profile (Sys Config menu).
You can cancel the backup process at any time by pressing Ctrl-C.
To save theDSL Terminator configuration (except passwords) to disk:
1
Open the Sys Diag menu.
2
Select Save Config, and press Enter.
The following message appears:
Ready to download - type any key to start....
3
Turn on the Capture feature of your communications program, and supply a filename for
the saved profiles. (Consult the documentation for your communications program if you
have any questions about how to turn on the Capture feature.)
4
Press any key to start saving your configured profiles.
Rows of configuration information appear on the screen as the configuration file is
downloaded to your hard disk. When the file has been saved, your communications
program displays a message indicating the download is complete.
5
Turn off the Capture feature of your communications program.
6
Print a copy of your configured profiles for later reference.
Examine the saved configuration file. Notice that some of the lines begin with START= and
other lines begin with END=. A pair of these START/STOP lines and the block of data between
them constitute a profile. If a parameter in a profile is set to its default value, it does not appear.
C-4
DSL Terminator Administration Guide
Upgrading System Software
Upgrading system software
In fact, you can have profiles with all parameters at their defaults, in which case the
corresponding START/STOP blocks are empty. Make sure that no extra lines of text or
characters either before START= or after END=. If there are, delete them. They could cause
problems when you try to upload the file to the DSL Terminator.
Uploading the software
To upload the software:
1
Type the following four-key sequence in rapid succession by pressing each key in the
sequence shown, one after the other, as quickly as possible:
Esc [ Esc (Press the Escape key, the Left Bracket key, the Escape key, and the Minus key, in that
order, in rapid succession.) The following string of Xmodem control characters appears:
CKCKCKCK
If you do not see these characters, you probably did not press the four-key sequence
quickly enough. Try again. Most people use both hands and keep one finger on the Escape
key.
2
Use the Xmodem file-transfer protocol to send the system file to the DSL Terminator.
Your communications program normally takes anywhere from 5 to 15 minutes to send the
file to your DSL Terminator. The time displayed on the screen does not represent real
time. Do not worry if your communication program displays several “bad batch”
messages. This is normal.
After the upload, the DSL Terminator resets. Upon completion of the self-test, the DSL
Terminator unit’s initial menu appears in the Edit window with all parameters set to default
values. This completes the upgrade.
If the upload fails during the transfer, try downloading another copy of the binary image from
the Lucent FTP server and reloading the code to the DSL Terminator. If you still have
problems, contact Lucent technical support for assistance.
Restoring the configuration
Under certain circumstances, the serial-port method might not completely restore your
configuration. For best results, therefore, verify that your configuration was properly restored
every time you use this method. If you have many profiles and passwords, consider using
TFTP to upgrade your software. (See “Using TFTP to upgrade” on page C-3.)
To restore the configuration, you must have administrative privileges that include Field Service
(such as the Full Access Profile, for example). You use the Restore Cfg command to
restore a full configuration that you saved by using the Save Cfg command, or to upload
more specific configuration information obtained from Lucent (for example, a single filter
stored in a special configuration file).
To load configuration information through the serial port, perform the following steps:
1
From the DSL Terminator unit’s VT100 interface, access the diagnostics monitor by
typing the following characters in rapid succession:
Esc [ Esc =
Or, press Ctrl-D to invoke the DO menu, and select D=Diagnostics.
2
At the > prompt, enter the Fclear command:
DSL Terminator Administration Guide
C-5
Upgrading System Software
Upgrading system software
> fclear
3
At the > prompt, enter the NVRAMClear command:
> nvramclear
This causes the system to reset. When it comes back up, proceed with restoring your
configuration.
4
Enter quit to exit the Diagnostic interface.
5
Open the Sys Diag menu.
6
Select Restore Cfg, and press Enter.
The following message appears:
Waiting for upload data...
7
Use the Send ASCII File feature of the communications software to send the configuration
file to the unit. (If you have any questions about how to send an ASCII file, consult the
documentation for your communications program.)
When the restore has been completed, the following message appears:
Restore complete - type any key to return to menu
8
Press any key to return to the configuration menus.
9
Reset the DSL Terminator, by selecting System > Sys Diag > Sys Reset and confirming
the reset.
Restoring passwords
For security, passwords are not written to configuration files created through the serial console.
A configuration file created using the Tsave command, however, does contain the system
passwords. You can restore the Tsave configuration file using the serial console.
After upgrading you may have to reenter all the passwords on your system. If you edit your
saved configuration file, however, and enter passwords in the appropriate fields (by replacing
the word *SECURE* in each instance), these passwords will be restored. But note that if you
do choose to edit your configuration file, you must save it as text only or you will not be able to
load it into your unit.
If you restored a complete configuration, the passwords used in your Security profiles have
been wiped out. To reset them:
C-6
1
Press Ctrl-D to invoke the DO menu, select Password, and choose the Full Access
profile.
2
When you are prompted to enter the password, press Enter (the null password).
After you have restored your privileges by entering the null password, immediately open
the Connection profiles, Security profiles, and Ethernet profile (Mod Config menu), and
reset the passwords to their previous values.

Use ‘tloadcode -f’
Indicates you are attempting to load a version of code
onto a platform for which it is not intended (for
example, loading MAX 6000 software onto a DSL
Terminator). This is not recommended.
Downgrading system software
The DSL Terminator expects a specific organization of the parameters in a configuration file.
When you upgrade, you can restore a configuration that was saved on an older release. The
DSL Terminator enters default values for parameters if the unit supports a parameter that is not
included in the configuration file.
When you downgrade to older versions of software, the configuration might not upload
completely, because older software does not support the parameters that might be in
configuration files from newer releases.
You must upload a configuration that was saved from the same version of software to make
sure that the unit receives a complete configuration. If you upload a configuration from a
newer version of software, you must check all parameter values to verify they are configured
accurately.
If you are downgrading system software, make sure that you have a configuration saved from a
DSL Terminator running with the older software and that you have console access to the unit.
Then, proceed as follows:
1
Use TFTP to load the system software.
2
Enter FCLEAR to clear the unit’s flash memory.
3
Enter NVRAMCLEAR to clear the unit’s main configuration and reset the DSL Terminator.
The DSL Terminator restarts and loads the older version of system software.
4
When the DSL Terminator is up, manually enter basic information, including IP address,
subnet mask, and default gateway to the Ethernet interface.
After entering you must be able to use Telnet to access the DSL Terminator.
5
From the DSL Terminator unit’s VT100 interface, access the diagnostics monitor by
