5.04 Intercom-Busy Station Signaling
(BSS)
Description
When the called extension user is busy talking on
a DN or CO button, and the ICM button is idle,
Intercom-Busy Station Signaling informs the
other extension user that he or she is called by
another extension through Intercom Calling with
the flashing ICM button.
The called extension user's telephone must be
off-hook.
To activate this function, assign "System-Class of
Service", BSS/OHCA to "Yes."
If the called extension user's telephone is PITS
KX-T123230D, KX-T123235 or KX-T7130, Busy
Station Signaling turns into Intercom Off-Hook
Call Announcement (OHCA).
Refer to the next page for further information.
BSS feature is available between the extension
