Using the Asynchronous Terminal
Interface

User Interface Access
You can communicate with the asynchronous terminal interface (ATI) using one
of the following methods:
H
Direct connection through the Management Serial port of the DSLAM (locally
or via an external modem).
H
Telnet session using a Network Management System (NMS) connected to a
LAN/WAN port on the DSLAM.
H
Telnet session through the Embedded Operations Channel (EOC).
NOTE:
Only one asynchronous terminal interface session can be active at a time,
and another user’s session cannot be forced to end. To automatically log out
a user due to inactivity, enable the Inactivity Timeout option (see Table A-5,
Telnet Session Options, in Appendix A, Configuration Option Tables).
Security can limit ATI access several ways. To set up security or a login ID, refer
to Chapter 7, Security.
Management Serial Port Settings
Ensure that the device you connect communicates using these settings:
H
Data rate set to 9.6 kbps.
H
Character length set to 8.
H
Parity set to None.
H
Stop Bits set to 1.
Refer to the installation document for your DSLAM.

Using the Asynchronous Terminal Interface
Logging In to the Hotwire DSLAM
You can log in to the Hotwire DSLAM system using either a local
VT100-compatible terminal or a remote Telnet connection.
After you enter your user ID and password, the system displays the Hotwire
Chassis Main Menu. See your Management Communications Controller (MCC)
documentation for information about selecting the unit from the MCC card
selection screen.
Initiating an ATI Session
The Main Menu screen is displayed on the screen unless a login ID and
password is required or the ATI is already in use.
If the ATI is already in use, the message connection refused is sent to a
terminal attempting Telnet access.
If security is enabled on the Hotwire 8774 Termination Unit and you used Telnet
to access it directly (you did not log in through the MCC), the system prompts you
for a login ID and password.

Remote Send Line Loopback
The local unit initiates this test by sending a line loopback Up or Down command
to the remote unit for 10 seconds. When the remote unit detects the loopback Up
command, it puts itself in line loopback and lights the front panel Test LED. The
remote unit remains in loopback until it receives a loopback Down command or
the remote unit’s test timeout value is exceeded. The Send Line Loopback tests
both units. External equipment can be used to verify the link.

Ending an Active Test
Except for the Remote Send Line Loopback and Remote DCLB, a test initiated by
the user can be ended by the user. Tests can also be terminated automatically by
enabling the Test Timeout option from the System Options Menu.
H
A Test Timeout option is available to automatically terminate a user-initiated
Loopback or Pattern test (as opposed to manually terminating a test) after it
has been running a specified period of time. The default is 10 minutes.
Refer to Table A-4, System Options.
H
On each test screen is a Command column. To manually stop a test, press
Enter when the cursor is on the Stop command.
H
Use the Abort All Tests selection from the Test menu to stop all tests running
on all interfaces, with the exception of network-initiated loopbacks. Command
Complete appears when all tests on all interfaces have been terminated.
An aborted test may continue to run for a few seconds as the abort command
is sent to the remote end and processed.

Controlling SNMP Access
There are three methods for limiting SNMP access:
H
Disable the SNMP management option. Refer to Table A-6, General SNMP
Management Options.
H
Assign SNMP community names and access types.
H
Limit SNMP access through validation of the IP address of each allowed
SNMP manager.
Assigning SNMP Community Names and Access Types
The unit can be managed by an SNMP manager supporting SNMP. The
community name must be supplied by an external SNMP manager accessing an
object in the MIB.
To define SNMP community names, follow this menu selection sequence:
Main Menu → Configuration → Load Configuration From → Edit →
SNMP → General SNMP Management
Refer to Table A-6, General SNMP Management Options, to:
H
Enable SNMP Management.
H
Assign the SNMP community names of the SNMP Managers that are allowed
to access the units Management Information Base (MIB).
H
Specify Read or Read/Write access for each SNMP community name.
Limiting SNMP Access through the IP Addresses of the Managers
The unit provides an additional level of security through validation of the IP
addresses.
The SNMP Management option must be enabled. To control SNMP access with
IP addresses, follow this menu selection sequence:
Main Menu → Configuration → Management → Security Menu
Refer to Table A-7, SNMP NMS Security Options. The SNMP access can be
limited by:
H
Enabling NMS IP address checking.
H
Add each IP address and access level.
NOTE:
Do not change or delete the IP address or access level of the NMS
performing the sets or enable IP address checking prior to adding the NMS to

Selecting an IP Addressing Scheme
Your IP addressing scheme depends in part whether the MCC controlling the
chassis is running IP Conservative software.
Configurations Not Running IP Conservative Software
In a configuration not running IP Conservative software, the NTU’s network
interface IP address is assigned through the peer IP address of the LTU’s
Network Interface menu.
The termination unit is assigned an IP address and subnet through the DSLAM
Configuration→ DSL Cards→ Set IP Address menu. Once the address is
assigned, you can use the ATI to assign:
H
Peer IP addresses to the four M/SDSL ports. These addresses are used as
the IP addresses of the remote units. See Table A-1, Network Interface
Options, in Appendix A, Configuration Option Tables.
H
An IP address for each NMS to act as a trap manager. See Table A-8,
SNMP Traps Options, in Appendix A, Configuration Option Tables.
All Configurations
The NTU obtains its IP address when the PPP link is established over the EOC.
Use the ATI to assign:
8774-A2-GB20-30
H
An IP address for each NMS. See Table A-7, SNMP NMS Security Options,
in Appendix A, Configuration Option Tables.
H
An IP address for the TFTP server you wish to use to upload and download
configurations. See Configuration Loader in Chapter 3, Initial Startup and
Configuration, and the documentation for your TFTP server.
July 1999
8-1
IP Addressing
Review the following information in preparation for selecting an IP addressing
scheme.
H
Any legal host address is allowed for a given subnet. The address choice
within the subnet is arbitrary.
H
A single route to a subnet is all that is needed to reach every device on a
subnet. The unit’s routing table supports a maximum of 20 routes.
