Selectable Calling Tone
Tie-line
The duration of the calling tone can be set for either 0.2
second (single note tone) or 0.3 second (warble tone).
It is also possible to have the station without any calling
tone.
Note.
1. The duration of the continuous calling tone is im-
possible to change.
2. Different modes of the duration of the calling tone
may not be employed in each station within the same
system.
Selectable Paging Pre-Announcement Tone Duration
The duration of the all-call and zone paging tones can be
set for either 2 seconds ("long") or 1 second ("short").
It is also possible to have the system without any paging
pre-announcement tone.
Time-Out of Conversation
It is possible to limit the conversation duration to one
through ninty-nine minutes in the unit of one minute in
order to improve speech path availability. A hurry-up
tone is sounded in both the calling and called stations
approximately 10 seconds before the busy stations are
automatically disconnected from the speech path.
Time-Out of Paging Call
This function is employed to prevent the unnecessary
line occupation as a result of a paging party's failure to
depress the
key after a paging call establishment. The
paging call is automatically cancelled after a certain
period of time, which may be set at one through ninty-
nine minutes in the unit of one minute, with a hurry-up
tone transmitted to the paging station approximately 10
seconds prior to the automatic disconnection. When the
paged party responds, the conversation is automatically
cut off after the duration set by the Time-out of con-
versation function.
