Recommendation S.4

Add the following new items 13), 14) and 15) in § 1:

13)	. one or more combinations No. 10 in figure-case after the call is established could trigger the transmission of a "conversation impossible" "CI" sequence of signals and/or a pre-recorded message from distant terminal (It should be noted that the combination No. 10 in figure-case could also be used to attract the operator's attention.).

14)	MMMM during a broadcast call, to signal the desire of the calling party to know those parties who cleared prematurely. See Recommendations U.44 and S.20.

Note - This sequence is to be recognized in letter shift mode only. A minimum of 4 Ms would clear a telex broadcast call, usage of a 5th or more Ms is a national matter.

15)	LLLL to signal the desire of the calling party to terminate the present call and to make a follow-on call as described in Recommendation U.43. Usuage of a 5th or more Ls is a national matter.

This combination should be recognized in letter shift mode only.
