Table 2-5.—R/T Message Showing All Possible Elements of the Address Components. FORMAT LINE 10 Format line 10 is identified by the proword GROUPS, followed by the number of groups, or “GROUP NO COUNT.” This line may contain an accounting symbol in addition to the group designation. Accounting symbols are seldom used on R/T circuits. However, they may appear on messages received for relay from circuits using other procedures. Accounting symbols are a combination of letters used to indicate the agency, service, or activity that assumes financial responsibility for the message. Since R/T messages are usually short, a group count is seldom used. However, if a group count is sent, the number of groups is preceded by the proword GROUPS and appears in the message prefix. When a message is transmitted before the group count is determined, the proword GROUP NO COUNT is used in lieu of the group count. The actual group count may then be transmitted in the final instructions and be inserted in the message prefix by the receiving operator. The proword GROUP NO COUNT is included in messages bearing an accounting symbol when groups are not counted. FORMAT LINES 11 THROUGH 16 Format line 11 contains the proword BREAK. This line separates the heading from the text. The use of this proword is not required except where confusion may be possible between the heading and text. Format line 12 is the text of the message and expresses the idea of the originator. The primary difference between R/T text and other types of communication is that R/T text must be spoken. Therefore, it is important that new operators thoroughly familiarize themselves with the proper phrases and prowords that are commonly used in communications texts. Format line 13 contains the proword BREAK. This line separates the text from the ending. Like format line 11, this proword should be used when confusion may occur between the text and the ending. Format line 14 is used only in abbreviated plaindress messages when a time group is transmitted here. When used, it takes the place of a DTG in format line 5. For example, a DTG may not be determined prior to transmission. In such cases, it may be omitted in format line 5 and be sent as a time group in format line 14. When used, format line 14 consists of the proword TIME, followed by the time group plus the zone suffix. For example, you are in time zone B and you are sending a time group of 310850 in format line 14. You would transmit the time group as: “TIME Three One Zero Eight Five Zero Bravo.” Format line 15 contains any final instructions. When used, this line may contain prowords (such as WAIT, CORRECTION, MORE TO FOLLOW, AUTHENTICATION IS), operating signals, address groups, call signs, and plain language designators. Format line 16 is identified by the proword OVER or OUT. Every transmission ends with either OVER or OUT. However, the proword OVER may be omitted when two stations are in continuous communication with each other on a circuit not shared with a third station. In transmissions where the proword DO NOT ANSWER is used, the transmissions must end with the Proword OUT. 2-13
