Introduction to Hotwire DSL
Routers 1
What is a Hotwire DSL Router?
The HotwirerDSL (Digital Subscriber Line) Router operates as an IP router
connecting a DSL link to an Ethernet network. This system provides high-speed
access to the Internet or a corporate network over a traditional twisted-pair
copper telephone line to the end user.
DSL Technologies Supported
Paradyne’s Hotwire DSL network supports the following types of technologies:
HHotwire IDSL (ISDN DSL) products provide IDSL multirate symmetric packet
transport and can operate over a connection with an ISDN repeater or digital
facilities. Data rates of 64 kbps, 128 kbps, or 144 kbps can be configured.
HHotwire RADSL (Rate Adaptive DSL) products are applicable for both
asymmetric and symmetric applications. The 1 Mbps symmetric operation is
ideal for traditional business applications while the 7 Mbps downstream with
1.1 Mbps upstream asymmetric operation provides added bandwidth for
corporate Internet access. RADSL products can also save line costs by
optionally supporting simultaneous data and voice over the same line.
HHotwire SDSL (Symmetric DSL) packet-based products provide high-speed
symmetric DSL services with bandwidth for business applications. These
products are configurable from 144 kbps up to 2.3 Mbps. This gives service
providers the opportunity to sell multiple services with a single product.

Typical DSL Router System
DSL is a local loop technology that uses standard twisted-pair copper wire to
support high-speed access over a single pair of twisted copper wires. DSL
applications are point-to-point, requiring DSL devices at the central site and at the
end-user site.
The Hotwire DSL routers interoperate with the following types of Hotwire IP DSL
cards (at the DSLAM/GranDSLAM chassis) to deliver applications at high speeds
in support of packet services over a DSL link:
HThe Hotwire 8303 or 8304 IP IDSL Cards interoperate with two Hotwire IDSL
Routers:
— Hotwire 6301 IDSL Router with one Ethernet port
— Hotwire 6302 IDSL Router with a 4-port Ethernet hub
HThe Hotwire 8343 or 8344 SDSL Cards interoperate with two Hotwire
Symmetric DSL Routers:
— Hotwire 6341 SDSL Router with one Ethernet port
— Hotwire 6342 SDSL Router with a 4-port Ethernet hub
HThe Hotwire 8510, 8373, and 8374 IP RADSL Cards interoperate with the
Hotwire 6371 RADSL Router with one Ethernet port
The following illustration shows a typical Hotwire system with a Hotwire DSL
Router. All Hotwire DSL routers transport data. The Hotwire 6371 RADSL Router
can transport data and POTS simultaneously.

Service Subscriber
The Service Subscriber is the user (or set of users) that has contracted to receive
networking services (e.g., Internet access, remote LAN access) for the end-user
system from an NSP (Network Service Provider). Service subscribers may be:
HResidential users connected to public network services (e.g., the Internet)
HWork-at-home users connected to their corporate intranet LAN
HCommercial users at corporate locations (e.g., branch offices) connected to
other corporate locations or connected to public network services
The Hotwire DSL Router must be installed at the customer premises to provide
the end user with access to any of the above services.
NOTE:
If you would like more information on DSL-based services, applications, and
network deployment, refer to Paradyne’s
The DSL Sourcebook. The book
may be downloaded or ordered through Paradyne’s World Wide Web site at
www.paradyne.com/library.

Accessing the DSL Router 2
Access Control to the DSL Router
The Hotwire DSL Router can be managed from an NMS using SNMP or from the
command line interface. There are two methods to access the command line
interface:
HLocal access at the DSL router through the Console port, or
HAccess by a Telnet session (controlled through the management interface at
the Hotwire chassis).
When a local console connection is first established, a login prompt appears. The
Hotwire DSL Router accepts only one login session at a time. The DSL Router is
configured at the factory with a default login ID and password. However, to
provide login security to the DSL system, configure a new login ID and password.
Levels of Access
There is one login ID and two levels of privileges on the Hotwire DSL system.
Your user account can be configured with one user name and different
passwords for:
HAdministrator. The Administrator has two levels of access to the DSL router.
— Administrator, non-configuration mode: Provides read-only capabilities.
This is the same level of access as Operator.
— Administrator, configuration mode: Provides complete write access to the
DSL router. However, MIB sets are done from the NMS vs. the command
line.
HOperator. The Operator has read-only access to display device information
with no modification permission and no access to management functions.
Refer to Appendix A,
Command Line Interface , for access level details for each
command line entry.

Changing Access Session Levels
HYou can change the Administrator access level by entering:
admin enable
This command provides Administrator access level privileges. The DSL
router will respond with a prompt to enter the password for Administrator
access.
HYou can end the Administrator access level by entering:
admin disable
This command results in ending the Administrator access level session. No
password is needed.
Entering exit has the same results. Refer to
Exiting from the System on
page 2-5 for further details on ending a session.
The Operator and Administrator have the same Login ID with different passwords
for their access level. To determine the level of access for a session, refer to
Determining the Current Access Level on page 2-4.
Local Console Access
The DSL router ships with the local console enabled. After login, the local console
can be disabled with the command console disable. After saving this change
and ending the session, there is no local access through the console port. Any
access must be through a Telnet session or the NMS.
NOTE:
Entering console disable results in NO local access to the DSL router.
If you attempt to log in, you will receive an error message.
To determine via a Telnet session if a console is enabled, enter:
show console
The display returned for the show console command will be:
Hconsole enabled – Command line management at the console is
available, or
Hconsole disabled – No command line management is available at the
console.
For steps to set up the new user’s login, refer to
Setting Up the New User’s Login
on page 2-3.

Setting Up the New User’s Login
The DSL router will provide the login prompt when the local console connection is
first established. When the login prompt appears, a locally connected console
defaults to Console Enabled with Operator access only.
"Procedure
For first-time access to the Hotwire DSL Router’s command line interface:
1. At the initial login> prompt, type the default login ID paradyne and press
Enter.
2. At the password> prompt (for Operator), type the default password abc123
and press Enter.
The login ID and password fields are validated together.
3. At the system identity of CUSTOMER> prompt, type admin enable and press
Enter.
4. At the password> prompt (for Administrator), type the default password
abc123 and press Enter.
5. The system identity will change to the Administrator display mode of
CUSTOMER#>. Type configure terminal and press Enter.
6. The system identity will change to the Administrator configuration mode of
CUSTOMER - CONFIG#>.
7. To change the login ID, enter text to replace the default of paradyne:
name
your new login ID
NOTE:
The Login ID and Password fields are NOT case-sensitive.
8. Enter a new password and specify the level:
password
level password
Example: type password operator 238clrd3 and press Enter.
Both the Login ID and the Password fields are 1–31 printable alphanumeric
ASCII characters in the ASCII hex range of 0x21–0x7E. No spaces are
allowed. The following table lists the invalid characters.
Invalid Characters Value ASCII Hex Translation
#Number sign 0x23
$Dollar sign 0x24

and press Enter
NOTE:
Any input during an Administrator configuration session must be saved
while still in configuration mode.
For more information regarding the system identity, refer to
Determining the
Current Access Level,
below.
If you are denied access during a Telnet session, the session stops and an error
is logged. If you accessing the DSL router locally and a Telnet session is active,
you will receive a message:
Local console disabled by conflict
Telnet Access
The Telnet access defaults to Administrator level. If the login is at the Operator
level, then Operator level access is available. Telnet access is always enabled.
Determining the Current Access Level
The command line prompt displays the access level. The factory default for
System identity is CUSTOMER>. You can set your own system identity name to
replace CUSTOMER. See the example below.
If the prompt format
appears as . . . Then the DSL router
access level is . . .
And if you entered a System
identity of PARADYNE, the
prompt displays . . .
CUSTOMER> Operator, display mode PARADYNE>
CUSTOMER #> Administrator, display
mode PARADYNE #>
CUSTOMER – CONFIG#> Administrator,
configuration mode PARADYNE – CONFIG#>
Determining the Available Commands
To determine the commands available at the current login access level, enter:
Hhelp or
H? (question mark)
Hthe command without any parameters

At the Local console and logged in at the
Administrator level, configuration mode You are placed at the Operator level and any configuration updates must be
saved or the updates will be lost.
At the Local console and logged in at the
Administrator level, non-configuration
mode
You are placed at the Operator level.
At the Local console and logged in at the
Operator level The Exit command responds exactly like the Logout command.
Via a Telnet session and logged in at any
access level Entering either of the following ends the Telnet session immediately:
HExit
HCtrl + ] (right bracket)
Automatically Logging Out
The DSL router has an automatic timeout feature that logs you out of the system
after five minutes of inactivity. Any input that is not saved is lost. You will need to
log back in.
At the console, press Enter to display the login> prompt to log back in. The
autologout {enable | disable} command default is enabled. Unsaved
configuration input is lost.
When autologout is:
HEnabled, the current configuration is retained through a power recycle.
