Single Tone Page Messages
Control Character
The control character 9920 must be entered before the actual page code when
building a
Single-Tone Page Message . If several single-tone pages are to be
sent, control character 9920 must exist before each page code.
Format
The format for single-tone page message is as follows:
•
Enter the control character 9920.
•
Enter four digits representing the frequency of the page tone, taken from
the Tone Code Table on page A-20.
•
Enter two digits representing the duration of the page tone in tenths of
seconds.
•
The range of duration is 0.1 to 9.9 seconds.
•
You may end the message with the (*) character, or enter another control
character (99xx) and continue with another message type.
For example, the format of a single-tone page of 1050Hz of 8.0 seconds
(National Weather Service standard page) is 9920095280.
Delays
A 1-second Pre-Page Delay is created by the message handler for the first page
in a group. If additional pages follow, the pre-page delay is eliminated in
succeeding pages. A 3- second
Post-Page Delay is created by the message
handler for all single-tone pages.
