About the TDM SHDSL Endpoint 1 TDM SHDSL Overview Hotwire® Time Division Multiplexer Symmetric High-bit-rate Digital Subscriber Line (TDM SHDSL) 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 products support autorate.
1. About the TDM SHDSL Endpoint TDM SHDSL Endpoint Features Hotwire TDM SHDSL Models 7995/7996 are endpoints for the chassis-mounted Hotwire 8799 Line Card that is housed in the Hotwire 8600 or 8800 Series Digital Subscriber Line Access Multiplexer (DSLAM). Two Hotwire TDM SHDSL endpoints can also be configured to operate in a central office SHDSL Transceiver Unit, Central Site (STU-C)-to-customer premises SHDSL Transceiver Unit, Remote Terminal Site (STU-R) environment.
1. About the TDM SHDSL Endpoint Network Configuration Figure 1-1, Sample Configurations, shows a network application using a DSLAM in a central office (CO). In this configuration, a frame relay switch and router are connected through the endpoint to partner units supporting a host or router and frame relay encapsulated or unframed data. The figure also shows a standalone-to-standalone configuration.

1. About the TDM SHDSL Endpoint SNMP Management Capabilities Hotwire Model 7995/7996 endpoints support SNMP Version 1, and can be managed by any industry-standard SNMP manager and accessed by external SNMP managers using SNMP. Management Information Base (MIB) Support For a detailed description of the supported MIBs, visit Paradyne’s Web site at www.paradyne.com. Select Technical Support → Online Support → MIBs.
1. About the TDM SHDSL Endpoint SNMP Trap Support The Hotwire Model 7995/7996 Endpoint supports traps as defined in RFC 1215. Figure 1-6, DSL SNMP Configuration, illustrates a typical DSL SNMP configuration. Figure 1-7, DSL Local SNMP Configuration, shows a DSL SNMP configuration where the NMS is connected directly to the endpoint’s Communications Port. Figure 1-8, Peer IP Address Assignment, shows an example of an IP addressing scheme.
1.
Using the Asynchronous Terminal Interface 2 User Interface Access You can communicate with the Hotwire TDM SHDSL endpoint with an asynchronous terminal interface (ATI) using one of the following methods: Direct connection through the COM port of the endpoint or through the serial port of the DSLAM management card. Telnet session through the Embedded Operations Channel (EOC). NOTE: Only one terminal interface session can be active at a time, and another user’s session cannot be forced to end.
2. Using the Asynchronous Terminal Interface 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, you will see: A connection refused or connection failed message (if you are using a Telnet session), or The IP address of the other user (if you are using the Management Serial port).
2. Using the Asynchronous Terminal Interface After you enter a valid login ID and password, the Main Menu appears. If you enter an invalid login ID and password after three attempts, the Telnet session closes or the terminal connection returns to an idle state. Refer to Chapter 5, Security.

Security 5 Overview Security on the Hotwire TDM SHDSL endpoint is implemented by limiting user access to the ATI through option settings. You can: Enable the Telnet Login Required option. Enable the COM port Login Required option. Limit access by setting a Session Access Level option of Operator for the Telnet session. Limit access by setting a Session Access Level option of Operator for the COM port. Disable Telnet access with the Telnet Session option.
5. Security ATI Access Levels The unit has two access levels: Administrator and Operator. The access level determines what functions are accessible, as shown in Table 5-1, Access Levels. Table 5-1. Access Levels ATI Access to Menu Functions Administrator Operator Status Read-Only Read-Only Test Full Access No Access Configuration Full Access Read-Only Control Full Access No Access Access levels can be applied to Login IDs, the COM port, and Telnet sessions.
5. Security Creating a Login Logins apply to the terminal directory connected to the communication port or Telnet access directly to the ATI of the unit. Six login ID/password combinations are available. Each Login ID and Password must be unique and include an access level. Procedure 1.
5. Security 3. Create the login by entering the following fields. Login IDs and passwords are case-sensitive. On the Login Entry screen, for the . . . Enter . . . Login ID 1 to 10 ASCII printable characters (hex21 through 7E). Blanks are not allowed. Password 1 to 10 ASCII printable characters that can consist of 0–9, a–z, A–Z, # (pound), . (period), – (dash), and / (slash). Re-enter Password 1 to 10 ASCII printable characters that can consist of 0–9, a–z, A–Z, # (pound), .
5. Security Resetting the Unit's COM Port or Factory Defaults The user interface can be rendered inaccessible with a faulty configuration. Two methods can be used to restore it: Reset COM Port – Allows you to reset the configuration options related to COM port usage. It also causes a device reset, where the TDM SHDSL endpoint performs a Device Self-Test. No security-related configuration options are changed.
5. Security Controlling SNMP Access There are three methods for limiting SNMP access: Disable the SNMP management option. Refer to Table A-10, 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.
