9.3.6 Time slot use (6,5)
The mapping of time slots can be viewed and configured via this menu (see
Figure 63).
The format of the display showing the current use of the time slots is as follows:
• Time slots can be freely selected between the ports.
• Time slots can be reserved only if they are not in use. Otherwise, they must
be first removed from the time slot map.
Mapping is performed between the line and ports, that is, you can reserve time
slots required for each port from the line, and the number of time slots defines the
speed used at the port (see Figure 80, TS use in line). Time slots can be
reorganised using the G.704 adapter (see Figure 80, TS mapping in Port 1-3).
9.3.7 Default settings (6,6)
The default settings are stored in the EEPROM. When installing DNT2Mi, the
settings can be changed using the front panel menus or Q1 management (see
Figure 63). Refer to Section 6.9 for the default values.
The default settings can be set separately to each DNT2Mi port and line. Selecting
the option 9 (All) returns all default settings into use except for service options,
that is, the Q1 speed and address.
To activate the settings, you have to answer 99 (Yes) after receiving a request for
confirmation. It takes about 60 seconds to save the information. If the power is
switched off during this time, factory settings will be written into the EEPROM.
During the saving process, you can use the equipment normally.
If you answer 1 (Cancel), the default settings will not be taken into use.
9.3.8 Factory settings (6,7)
Factory settings can be loaded by using this menu (see Figure 63).
With this setting, it is possible to reset the EEPROM and to restore default
structures and settings into use. Refer to Sections 6.9 and 6.10 for the default and
factory values.
To activate the settings, you have to answer 99 (Yes) after receiving a request for
confirmation. It takes about 60 seconds to save the information.
If you answer 1 (Cancel), the factory settings will not be taken into use.
