Firmware Updates
Firmware can be updated by using XMODEM transfer protocol via the unit’s CRAFT port (see Figure 1) or by using TFTP from a network server. (See Appendix B on page 51 and Appendix C on page 54.)
Terminal Menu
The terminal menu is the access point to all other operations. Each terminal menu item has several functions and sub- menus that identify and provide access to specific operations and parameters. These menu selections are described later in this User Manual.
See Appendix D on page 57 for instructions about navigating the terminal menus.
2.VOICE OVER DSL OVERVIEW
Voice over DSL (VoDSL) refers to providing toll quality voice access to the Public Switched Telephone Network (PSTN) over twisted copper pair using DSL. Data can be combined with multiple voice lines over a single medium via DSL, thus yielding many advantages over traditional TDM technologies.
Traditional TDM technologies are limited by statically allocating bandwidth. DSL overcomes this by providing a large bandwidth and utilizing other technologies, such as ATM, to dynamically assign bandwidth as it is needed. Because of this, the user is able to add voice and data connections over a DSL line with flexibility and ease.
3.VOICE OVER ATM OVERVIEW
Voice over ATM is the technology used to transmit voice conversations over a data network using Asynchronous Transfer Mode (ATM). There are several potential benefits to moving voice over a data network using ATM. First, the
