4.4.1.4.1.1 When the receiving station detects that one or
more channel-sequence numbers are missing, it shall send a
complete service message (see 4.4.1.1.9) to the previous
station rejecting receipt of any message that may have been
transmitted with such missing number(s). The text of this
service message shall comprise the signal QTA, the procedure
signal MIS followed by one or more missing transmission
identification (see 4.4.2.1.1.3 and 4.4.15.1.1.4) and the endof-
text signal (see 4.4.5.6 and 4.4.15.3.12).

above-mentioned procedure. In example 2) the hyphen (-)
separator is understood to mean "through" in plain language.

4.4.1.4.2 Misrouted messages
N o t e . A message is considered to have been misrouted
when it contains no relaying instructions, expressed or
implied, on which the receiving station can take action.
4.4.1.4.2.1 When the receiving station detects that a
message has been misrouted to it, it shall either:
1) send a service message (see 4.4.1.1.9) to the previous
station rejecting receipt of the misrouted message; or
2) itself assume responsibility for transmission of the
message to all addressee indicators.
N o t e . The procedure of I ) is preferable at stations using
"torn-tape" relay methodLs or a semi-automatic relay
technique with continuous tape. The procedure of 2) may be
preferred at stations using,fully automatic relay methods or a
semi-automatic relay technique without continuous tape.
