ADTRAN 3060 specifications Menus, Screen Abbreviations

Many portable personal computers use power-saving programs that are known to interfere with applications running on the personal computer. If using a portable personal computer with terminal emulation capability, communication between the computer and the HDSL unit may be periodically disrupted if power-saving programs are being used on the personal computer. The symptoms may include misplaced characters appearing on the screen and/or the occurrence of screen timeouts. These symptoms are not disruptive to the operation of the circuit and are avoidable if the power-saving options are disabled or removed.

For abbreviations used in the screen diagrams, see Table 2.

The screens illustrated in Figure 6 through Figure 18 are for an HDSL circuit deployed with ADTRAN’s Low Voltage HDSL technology. The circuit includes an LTU, NTU, and two REG. This scenario was chosen for inclusiveness of functionality. However, other configurations are possible, such as one REGs, and the display will vary slightly from those shown in this section.
