• For a protected Terminal link, the primary and secondary Terminals are
displayed on separate screens.
• For a protected Node link, the degree of synchronization between RACs for
frequency, modulation, Tx power and ATPC settings depends on the type of
protection selected. Where not synchronized, separate configuration of
relevant settings is prompted/required.
2. Capacity. Click Capacity to view and select an option from the submenu.
• The options shown are those permitted within the capabilities of the installed
RAC/ODU, or IDU/ODU combination.
• The options permitted are those which are not flagged with a warning icon.
Cross icons are displayed against capacities requiring a different backplane
bus setting.
For a Node, the selected capacity type (E1, DS1, E3, DS3 or STM1/OC3)
must have a matching backplane bus. When a selected capacity option does
not match with the bus, a 'cross' icon is displayed against it. For example, if
an NxSTM1 capacity option is selected, the bus must also be configured for
STM1 operation. This backplane configuration is selected in the Circuits
screen. E1 is the default backplane configuration.
The selected capacity must be supported by the licensed capacity. If the
configured capacity exceeds the licensed capacity a configuration not
supported alarm is raised. This is a major alarm.
• An enhanced system gain option is included for RAC 30v3 for 1xSTM1,
128QAM. This is in addition to the standard option provided for this
capacity/bandwidth.
• The enhanced system gain option, 1xSTM1+, improves Rx threshold
and system gain by 1.5dB compared to the standard 1xSTM1 option.
• For all protected configurations except Ring, the selected capacity is
common to both RACs.
• Both RACs in a protected pairing must have a valid license.
The Node backplane bus must be set to match the capacity type selected in the
plug-ins screen. The selection options are E1, DS1, E3, DS3 or STM1/OC3.
Configuration of the bus is made in the Circuits screen.
3. Bandwidth / Modulation. Select bandwidth / modulation from its submenu.
• The bandwidth / modulation options presented are only those permitted by
the selected capacity for the RAC/ODU or IDU/ODU type installed.
