About Hotwire 8775 and 8785 Termination Units

TDM SDSL Overview

Hotwire® Time Division Multiplexer Symmetric Digital Subscriber Line (TDM SDSL) products maximize customer service areas by varying the DSL line rate. This ensures symmetric DSL connectivity over a wide range of telephone line distances and transmission line qualities.

Hotwire TDM SDSL products support router, multiplexer and PBX connections with maximum loop reaches, as shown in Table 1-1, Maximum Loop Reach.

Table 1-1. Maximum Loop Reach

Transmission Rate

Model

8775 (over 2-wire loop) 8.8 km (29,000 ft) 4.5 km (14,700 ft) 8785 (over 4-wire loop) 10.7 km (35,000 ft) 6.0 km (19,600 ft)

Hotwire 8775 and 8785 Termination Units are equipped with an automatic configuration capability that reduces the installation process to a simple plug-and-play mode. Simply connecting the units to the line automatically configures the customer for the maximum data rate supported by the local loop. Units can also be configured at fixed line speeds to achieve maximum distances.

Using the Asynchronous Terminal Interface

User Interface Access

You can communicate with the asynchronous terminal interface (ATI) using one of the following methods:



Direct connection through the Management Serial port of the DSLAM (locally or via an external modem).



Telnet session using a Network Management System (NMS) connected to a LAN/WAN port on the DSLAM.



Telnet session through the Embedded Operations Channel (EOC).

NOTE:

Only one ATI 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. To enable the Inactivity Timeout option, refer to Table A-5, Telnet Session Options, in Appendix A,

Options

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:



Data rate set to 9.6 kbps.



Character length set to 8.



Parity set to None.



Stop Bits set to 1.

Refer to the installation document for your DS LAM.

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 card documentation for information about selecting the unit from the card selection screen.

Initiating an ATI Session

The Main Menu screen is displayed 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 and Telnet is used to access the terminal unit directly (you did

not log in through the MCC), the system prompts you for a login ID and password.

Procedure

To upload or download a configuration:

1. Position the cursor in the Image File Name field. Type the name of the file to

—

If the TFTP server is hosted by a DOS machine, then directory and filenames must consist of eight or less characters with an optional suffix of up to three characters. The system will automatically upload the configuration file and create directories and filenames as needed.

UNIX machine:

—

If your server is hosted by a UNIX machine, the configuration file you name must already exist. It will not be create d on the UNIX system by the TFTP server. It is critical that you work with your system administrator to plan the naming conventions for directories, filenames, and permissions so that anyone using the system has read and write permissions.

2. Positi on the cursor in the TFTP Se rver IP Address field. Enter the TFTP server IP address.

The first three digits of the IP address cannot be 000 or greater than 223.

3. Position the cursor in the TFTP Transfer Direction field. Use the spacebar to select Download from Server or Upload to Server.

4. Position the cursor in the Destination field. Use the spacebar to select a network destination for the TFTP server. Select DSL

if the TFTP server destination is the DSL link or IMC if the TFTP destination is the Management port of the management card. (Destination is not available and IMC is assumed if the DSL mode is LTU.)

Overview

The Hotwire Termination Unit provides several methods of limiting user access to the ATI through option settings. You can:



Enable the Telnet Login Required option.



Limit the access by setting a Session Access Level option of Operator for the Telnet Session.



Disable the access with the Telnet Session option.

See Table A-5, Telnet Session Options, in Appendix A,

ATI Access Levels

The unit has two access levels: Administrator and Operator. The access level determines what functions are accessible, as shown in Table 7-1, Access Levels.

Table 7-1. Access Levels

ATI Access to Menu Functions Administrator Operator

Access levels can be applied to Login IDs and Telnet sessions. When access is through Telnet and a login is required for Telnet, the effective access level is the more restrictive of the Telnet session access level or the login access level (see

IP Addressing

Selecting an IP Addressing Scheme

Your IP addressing scheme depends in part upon whether the management card 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 L TU's Network Interface menu.

All Configurations

Trap Options, in Appendix A,

The NTU obtains its IP address when the PPP link is established over the EOC. Use the ATI to assign:

Any legal host address is allowed for a given subnet. The address choice within the subnet is arbitrary.

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.
