3. The sub-line of the two-line D

Conditions by PS
1. This feature does not support the CALL FORWARDING - DROPPED CALLS [C-161] / AUTOMATIC
ANNOUNCEMENT - DISCONNECTED PS OUT OF ZONE [A-128] / AUTOMATIC
ANNOUNCEMENT - CALLED PS OUT OF ZONE [A-129] feature. Accordingly, if a PS is once out of

data communication. Accordingly, if the communication is in progress, the third incoming call (including
that by another data terminal) is not forwarded to the target destination (i.e. disconnected).
5. CALL FORWARDING - DON’T ANSWER, assigned to a PS, does not function if the PS is just engaged
in data communication. Accordingly, if the communication is in progress, the third incoming call
(including that by another data terminal) is not forwarded to the target destination (i.e. disconnected after
a certain period of time).
6. CALL FORWARDING - ALL CALLS, assigned to a PS, does not function if the PS is just engaged in
data communication. Accordingly, if the communication is in progress, the third incoming call (including
that by another data terminal) is not forwarded to the target destination (i.e. disconnected).
