Talk:16-line message format

Sample Messages
Here are some sample messages I wrote. RI=Routing indicator PLAD=Plain language address. ACP 126 ACP 127

ACP 127 Supl.

These are correct as used on US Army circuits. Jbh (talk) 18:59, 22 April 2015 (UTC)

All 16 line definitions
Here are the message line definitions I pulled from the [//www.state.gov/documents/organization/89289.pdf DOS reference] I mentioned on my talk page. Line 10, group count, is not from the reference but is documented elsewhere. Line 12 is where much inter-agency/inter-service variation occurs. I never realized a lot of the formatting I am used to is not actually part of the standard but is just variant line 12 formatting. Learn something every day! Cheers.

Would something like this help you make sense of the DOS material?
I tried extracting material from the DOS publication based on what I know. If a 'translation' like I have done below would be of help to you please let me know and I will work through all of the lines of the format in the same way I started or if you have particular lines which are an issue I can just do them. Format lines 1 through 10 specify the header of an ACP-127 standard message. These lines consist of both printing and non-printing characters that provide information both to human operators and automated message terminals (AMT).
 * Line 1 Is the Transmission Identifier it provides Start-of-Message (SOM) information to the AMT consisting of two characters followed bt five spaces, two carrage returns and a line feed. Following this is infromation visible to the operator consisting of a single letter Start-of-Transmision (SOT) indicator and a four character Start-of-Message (SOM) indicator. These letters stay the same for all transmissions. Following the SOM is an alphabetic trigraph followed by three digits. These can vary from message to message as defined by the agency operating the communications system. Often these are used to identify the transmissin channel and message number. A properly formatted Line 1 would look like this: VZCZCAAA123
 * Line 2 Consists of a digraph indicating message presidence followed by a space and then the routing indicator or call sign of either the next relay station or the final addressee. There are typically four levels of precidence. From lowest to highest they are
 * Routine indicated by RR
 * Priority indicated by PP
 * Immediate sometimes referred to as Operational Immediate is indicated by OO
 * Flash indicated by ZZ
 * A properly formatted Line 2 for a routine message would look like this: RR BA9HQM
