or as a result of a voted signal being present while T/T is on.
(b). ‘ Talk Thru ’ – lit Yellow when the channel has T/T switched on either by an input signal to a
Central NI or a setting of the TM Setup.
(c). ‘ Voted Site ’ – the number of the site currently selected as offering the best incoming signal is
displayed. The number is that of the station panel for that site.

The status window for Central NI #N (where N is the number of the NI) is selected by clicking on

Figure 20. Central NI #1 Status Panel.
The Central NI Status Panel tab gains a Green highlight when selected as does the Channel ‘Chn:’
#N tab to which the Central NI has been assigned. All the Station Interface Panels that are
members of the Channel will also gain the Green highlight. The example in Figure 20 shows
Central NI #1 selected, which operates Channel #1.
The facility accessed using the Network button is covered in Section 4.4.4 – Allocating a Central
NI . The button (no legend) in the ‘Central’ area provides access to the remote view of the Central
NI for engineering purposes.
3.4.3.1 Central Indicators
(a). ‘ Status ’ – lit Green when network communications with the Central NI is established and
Red if it fails. This may be assigned ‘Alarm’ status – see Section 12 – Alarms .
(b). ‘ Tx Key ’ – lit Yellow when the Central NI has a PTT applied from a control or console input.
(c). ‘ Talk Thru ’ – lit Yellow when the Central NI has the T/T input signal applied. The indicator
and text will be disabled (greyed out) if the Central NI is not configured for control of T/T –
see Figure 28 as an example and Section 5.2.2.4 – Isolated Inputs for details on
