c) the message-separation signal, consisting of a LETTER SHIFT [↓] transmitted 12 times in uninterrupted sequence. Note 1.— Nothing but letter shifts are to be transmitted in message traffic between the end-of-message signal of one message and the start-of-message signal of the next. Note 2.— The following illustrates the procedures specified in 4.4.2 to 4.4.6.1 inclusive for a message in page-copy form: (Heading) *ZCZC LPA183 (Address) GG LGGGZRZX LGATKLMW (Origin) 201838 EGLLKLMW (Text) As required (Ending) (Page feed) NNNN** *Note 2A.— If this message had been one of a series and there had been no manual paper-feed action between messages by the operator attending the receiving page teletypewriter, the “NNNN” of the preceding message would have appeared here. **Note 2B.— In the circumstances described in Note 2A, the heading of the next message received would be printed on page-copy at this position. Note 2C.— In actual station practice, messages would be separated on page-copy by tearing through the page-feed sequence. The end-of-message signal would then appear to have become a component part of the next message. This apparent misplacement is, however, unlikely to give rise to any misunderstanding on the part of communicators or addressees since, in practice, the end-of-message signal has no significance on page-copy. 4.4.6.2 AFTN messages entered by the AFTN origin station shall not exceed 2 100 characters in length. Note.— The character count includes all printing and non-printing characters in the message from and including the start-of-message signal (ZCZC) to and including the end-ofmessage signal (NNNN). 4.4.7 Tape feed 4.4.7.1 Recommendation.— In “torn-tape” installations, and in “semi-automatic” installations using continuous tape technique, when signals additional to those prescribed in 4.4.6.1 are required to ensure that the tape is 27/11/03 No. 78 Chapter 4 Annex 10 — Aeronautical Telecommunications 4-21 1/11/01 4.4.15 Message format — International Alphabet No. 5 (IA-5) When it has been agreed between the Administrations concerned to use International Alphabet No. 5 (IA-5) the format described in 4.4.15 through 4.4.15.3 shall be used. It shall be the responsibility of Administrations using IA-5 to accommodate adjacent AFTN stations employing ITA-2 code in the format described in 4.4.2. All messages, other than those prescribed in 4.4.1.8 and 4.4.9.3 shall comprise the components specified in 4.4.15.1 to 4.4.15.6 inclusive. Note 1.— An illustration of the IA-5 message format is given in Figure 4-4. Note 2.— In the subsequent standards relative to message format the following symbols have been used in making reference to the functions assigned to certain signals in IA-5. (See Volume III, Part I, 8.6.1 and Tables 8-2 and 8-3.) Symbol Signification < CARRIAGE RETURN (character position 0/13) ≡ LINE FEED (character position 0/10) → SPACE (character position 2/0). 4.4.15.1 Heading 4.4.15.1.1 The heading shall comprise:
