RT-9000 B
In this example, NCXXSUN1 H XX = The RT-9000 B Network Number in which the Initiating
station’s CALL ID, SUN1 is contained.
Figure 7.3.4.29 ALE ‘NET CALL’ – Receiving Station Display
After listening for responses from Network stations, the Initiating station will broadcast a “Net
Acknowledgement” (‘NA’) message to all Network stations. After general traffic has been passed, the RT-
9000 B -equipped station will continue to listen. If no additional traffic is heard for approximately 30 seconds,
the RT-9000 B -equipped station will automatically resume Receive scanning.
Figure 7.3.4.30 shows the “Net Acknowledgement” message received and displayed by the RT-9000 B -
equipped station. The RT-9000 B will append the RT-9000 B ’s local ALE Network Number where the Initiating
station’s SELF ID resides to the “NA” Operation Indicator.
After the NET CALL process is finished, the RT-9000 B will resume Receiver scanning but continue to display
the last NET CALL transmission information until more recent ALE activity overwrites it or the operator leaves
ALE mode.
In this example, NAXXSUN1 H XX = The RT-9000 B Network Number in which the Initiating
station’s CALL ID, SUN1 is contained.

7.3.4.7 ALL CALL
The ALL CALL calling method calls all Network Stations on a single frequency (or Channel) during the same
call. An ALL CALL does not expect a response.
The ALL CALL calling method can be used to broadcast a message, usually an Automatic Message Display
(AMD) message to all stations. Using the AMD capability requires use of an external terminal for message
composition and reception. Refer to Section VI of the RT-9000A Operation and Maintenance manual for
details.
