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 2-wire TDM SDSL products  
transmit data over 14,000 feet (4.6 km) at rates up to 2.048 Mbps.  
Hotwire products support autorate. Units first synchronize to the highest line rate  
that the 2-wire loop supports, then automatically configures the unit to the highest  
multiple of 64 Kbps supported by that line rate. Eight line rates are available. At all  
rates, an 8 Kbps management channel is available, which enables functions such  
as firmware downloads to remote units. Units can also be configured manually to  
full or fractional T1 or E1 rates.

— Network Management System (NMS) via the Management MCC port of  
the DSLAM through the port card’s 10BaseT port  
Remote Management. Provides remote management:  
— Out-of-band, using an external modem through the Management Serial  
port of the DSLAM  
— Inband using one of the DS0 channels as the management channel to  
transport SNMP traffic to the MCC card (Model 8779 only).  
— Via Telnet over the EOC  
Alarm Indication. Activates front panel LEDs.  
Diagnostics. Provides the capability to diagnose device and network  
problems and perform tests, including digital loopbacks, pattern tests, and

industry-standard SNMP manager and accessed using SNMP by external SNMP  
managers.  
Management Information Base (MIB) Support  
For a detailed description of supported MIBs, visit Paradyne’s Web site at  
www.paradyne.com. The following MIBs are supported:  
MIB II (RFC 1213 and RFC 2863 (was 1573)) – Defines the general objects  
for use with a network management protocol in TCP/IP internets and provides  
general information about the unit. MIB II is backward-compatible with MIB I.  
DS1/E1 MIB (RFC 2495 (was 1406)) – Reports the performance status of the  
DSX-1 or G.703 interface and supports the features found on the DSX-1 or  
G.703 Performance Statistics screen.  
Entity MIB (RFC 2037) – Supports all DSLAM cards.  
Enterprise MIBs – Supports configuration, status, statistics, and tests.  
SNMP Trap Support  
The Hotwire 8777 or 8779 TDM SDSL Termination Unit supports SNMP traps as  
shown in Appendix B, Standards Compliance for SNMP Traps.

Using the Asynchronous Terminal  
Interface  
2
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 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-12,  
Telnet Session Options, in Appendix A, Configuration Options).  
Security can limit ATI access in several ways. To set up security or a login ID, refer  
to Chapter 6, 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 DSLAM. See Product-Related  
Documents in About This Guide.

2. 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 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 security is enabled on the termination unit and Telnet is used to access the unit  
directly (you did not log in through the MCC), the system prompts you for a login  
ID and password.  
Login  
Slot: 4  
Model: 87xx

Login ID:  
Enter Password:  
--------------------------------------------------------------------------------  
Ctrl-a to access these functions Exit  
If you enter an invalid login ID and password three times, the Telnet session closes  
or the terminal connection returns to an idle state. Refer to Chapter 6, Security.  
If the ATI is already in use, the message connection refused is sent to a  
terminal attempting Telnet access.

Procedure  
To upload or download a configuration:  
1. Position the cursor in the Image File Name field. Type the name of the file to  
be downloaded, or the name to be used for the file to be uploaded.  
The filename may be a regular path name expression of directory names  
separated by a forward slash (/) ending with the filename. The total path name  
length can be up to 128 characters.  
— DOS machine: 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 created 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.  
— MCP FFS: When uploading configuration files to the MCP FFS, the  
directory and filename must be entered, otherwise the download will fail.

Cross-Connecting Ports  
4
Overview  
Configuration of the cross-connections consists of the following steps:  
❑ Determine how the ports will be connected and configured.  
❑ On the Network Interface Options screen, enable the DSL ports that will be in  
the cross-connection if necessary. The ports are enabled by default.  
❑ On the DSX-1 or G.703 Interface Options screen, enable the DSX-1 or G.703  
ports that will be in the cross-connection.  
For G.703, specify whether Time Slot 16 is used for signaling (voice mode).  
❑ On the System Clock screen, configure the system clock.  
❑ On the Cross-Connect Mode screen:  
— Define all DS1 Bypass ports.  
— Define all DS1 Cross-Connect ports.  
— Define all DS0 Cross-Connect ports.  
❑ On the Assign Time Slots screen, configure the DS0 cross-connections.  
This chapter describes the use of the Cross-Connect Mode and Assign Time Slots  
screens. See Appendix A, Configuration Options, for information about  
configuration options presented on the other screens.  
Examples in this chapter show screens for DSX-1 models. The principles of  
cross-connection are the same for G.703 models.  
IMPORTANT:  
All DSL time slots are available for cross-connect regardless of DSL line  
rate, but all time slots are available for data transport only if the DSL line  
rate is the full rate (1552 for DSX-1 or 2064 for G.703). Configure only the  
time slots intended for use.

4. Cross-Connecting Ports  
Determining the Configuration  
The Hotwire cross-connect system allows you to connect the DSX-1 or G.703  
ports to the DSL ports in a variety of ways:  
DS1 Bypass mode – The entire DSX-1 or G.703 interface is connected to the  
DSL interface.  
DS1 Cross-Connect mode (8777) – The entire DSX-1 interface is connected  
to the DSL interface through cross-connect circuitry. Ports can be switched  
through software.  
DS1 Cross-Connect mode (8779) – The entire G.703 interface can be  
connected to any DSL or G.703 interface. The entire DSL interface can be  
connected to any DSL or G.703 interface through cross-connect circuitry.  
Ports can be switched through software.  
DS0 Cross-Connect mode (8777) – Any time slot of any DSX-1 interface can  
be connected to any time slot of any DSL interface. Time slots can be  
individually allocated for voice or data.  
DS0 Cross-Connect mode (8779) – Any time slot of any DSL interface can  
be connected to any time slot of any G.703 or DSL interface. Any time slot of  
any G.703 interface can be connected to any time slot of any G.703 or DSL  
interface. Time slots can be individually allocated for voice or data.  
The example below shows a DS0 cross-connection between DSX-1  
Ports 1 and 2. DSX-1 Port 1 is dedicated to voice and Port 2 to data.

NOTES:  
— Although the example shows ports dedicated to voice or data, a port can  
be configured for both voice and data.  
— For G.703 ports using Common Channel Signaling (CCS) that are in DS0  
Cross-Connect mode, you must explicitly configure the cross-connections  
for Time Slot 16 and related time slots.  
You may find it useful to diagram your configuration. Appendix E,  
Cross-Connection Worksheets, contains a skeleton diagram for this purpose.  
It also contains worksheets for documenting your time slot cross-connections  
before you begin to configure them.

IP Addressing  
5
Selecting an IP Addressing Scheme  
Your IP addressing scheme depends in part 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 LTU’s Network  
Interface menu.  
The termination unit is assigned an IP address and subnet through the DSLAM’s  
Configuration → DSL Cards → Set IP Address menu. Once the address is  
assigned, you can use the ATI to assign:  
Peer IP addresses to the DSL ports. These addresses are used as the IP  
addresses of the remote units, and must be in the same subnet as the DSLAM  
management card. See Table A-1, Network Interface Options, in Appendix A,  
Configuration Options.  
An IP address for each NMS to act as a trap manager. See Table A-15, SNMP  
Traps Options, in Appendix A, Configuration Options.

5. IP Addressing  
All Configurations  
The NTU obtains its IP address when the PPP link is established over the EOC.  
Use the ATI to assign:  
An IP address for each NMS. See Table A-14, SNMP NMS Security Options,  
in Appendix A, Configuration Options.  
An IP address for the TFTP server you wish to use to upload and download  
configurations. See Configuration Loader in Chapter 9, Transferring Firmware  
and Configurations Using TFTP, and the documentation for your TFTP server.  
Review the following information in preparation for selecting an IP addressing  
scheme.  
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.  
IP Addressing Example  
Figure 5-1, Peer IP Address Assignments, shows IP addressing in a typical  
network. Note that the Peer IP Address:  
Refers to the IP address of the unit configured as an NTU.  
Is assigned by the LTU.

Overview  
The Hotwire Termination Unit in IP Complex mode 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-12, Telnet Session Options, in Appendix A, Configuration Options.

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  
Table A-12, Telnet Session Options, in Appendix A, Configuration Options.)  
When an access level of Operator is applied to Telnet sessions, a Login ID  
with Administrator authority is effectively reduced to Operator. It is no longer  
possible to change configuration options, and full access can be restored only by  
reloading factory defaults. (See Restoring Access to the User Interface in  
Chapter 3, Initial Startup and Configuration.)

Controlling SNMP Access  
There are three methods for limiting SNMP access.  
Disable the SNMP management option. Refer to Table A-13, General SNMP  
Management Options, in Appendix A, Configuration Options.  
Assign SNMP community names and access types.  
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→ Current Configuration→  
Management and Communication→ General SNMP Management  
Refer to Table A-13, General SNMP Management Options, in Appendix A,  
Configuration Options, to:  
Enable SNMP Management.  
Assign the SNMP community names of the SNMP Managers that are allowed  
to access the unit’s Management Information Base (MIB).  
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→ Current Configuration →  
Management and Communication→ SNMP NMS Security  
Refer to Table A-14, SNMP NMS Security Options, in Appendix A, Configuration  
Options. The SNMP access can be limited by:  
Enabling NMS IP address checking.  
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 the table.

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.

Procedure  
To upload or download a configuration:  
1. Position the cursor in the Image File Name field. Type the name of the file to  
be downloaded, or the name to be used for the file to be uploaded.  
The file name may be a regular path name expression of directory names  
separated by a forward slash (/) ending with the file name. The total path  
name length can be up to 128 characters.  
— DOS machine: 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 created 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.  
— MCP FFS: When uploading configuration files to the MCP FFS, the  
directory and filename must be entered, otherwise the download will fail.

A. Configuration Options  
System Clock  
The Primary and Secondary System Clock References determine the clock used  
by ports in a cross-connect configuration. For System Clock configuration options,  
refer to Table A-8, System Clock Options. To access the System Clock screen,  
follow this menu selection sequence:  
Main Menu→ Configuration→ Current Configuration→ System Clock  
main/config/system_clock  
Slot: 18  
Model: 87xx

MainMenu  
Exit  
All ports configured as system clock sources must be traceable to the same clock  
reference. Ports in a cross-connect configuration that are not providing timing  
themselves receive their timing from the system clock reference. All ports in a  
cross-connect configuration are therefore synchronized to the system clock  
reference.  
On an LTU, the system clocks may be sourced from the DSX-1/G.703 interface  
which is generating timing, or from the internal oscillator on the card (providing a  
Stratum 4 reference). Typically, the primary clock source is a DSX-1/G.703 port  
which is being used in a cross-connection. The LTU secondary clock sources are  
restricted to G.703 ports configured for Bypass mode. On an LTU when the  
system clock is configured for something other than internal, DSX-1/G.703 ports  
configured for Bypass mode and internal timing will use the user-specified clock as  
their reference.  
On an NTU, the system clock may only be sourced from DSL ports being used in a  
cross-connection. If all ports on an NTU are configured for Bypass mode, no  
configuration for system clock is required (primary and secondary clock should  
remain set to their default values).

A. Configuration Options  
When a system clock source fails or is misconfigured, an alarm is reported.  
Secondary clock failures are not reported unless the primary clock has also failed.  
When the primary clock fails, clocking is switched to the secondary clock source, if  
available. If a secondary clock is not available, the clock switches to secondary  
holdover mode. In holdover mode, the system attempts to generate timing which is  
consistent with the last clock reference. A switch is made back to the primary clock  
when it becomes available. Holdover mode is meant to be used for short durations  
while network synchronization is temporarily disrupted. The switch back to  
primary/secondary clock is made when they become available again.

Procedure  
To test the inband management configuration:  
1. Connect the G.703 port to the MUX/DCAS to be used in the test.  
2. Configure the upstream router for PPP mode. The router’s WAN port should  
be configured on the same IP address segment as the MCP card.

15–22  
39–46  
For a unit defined as an LTU running IP Conservative software or a unit not  
running IP Conservative software, all traps have at a minimum a variable binding  
of the Overloaded ifIndex (OI). The formula for the OI is:  
((LTU Slot Number) * 1,000)  
+ ifIndex.

Using the Worksheets  
The following worksheets are designed to help plan, visualize, and configure a  
cross-connection. Time slot assignment worksheets are supplied to represent a  
connection from the viewpoint of the DSX-1 or G.703 ports, or the associated DSL  
ports. The unit can be configured using either viewpoint, so it may not be  
necessary or useful to fill in all the worksheets.  
Use the completed port connection diagram and time slot assignment worksheets  
to configure the cross-connection using the Cross-Connect Mode and Assign Time  
Slots screens. See Chapter 4, Cross-Connecting Ports, for an example of  
cross-connection.
