Calling Party Indication (Lamp Type)
A one station/one lamp type calling party indication panel
can be provided for certain specified stations (eight stations
or eight groups of statio ns)
The system can also be divided into a maximum of 8 groups
of stations (consecutive station numbers) so that each
group may have the calling party indication panels which
are common within the group. The party making the call is
indicated even if the call is made to any station in the group.
<Calling station memory>
It is also possible to equip the system with the "Calling

station Memory" function. Adopting this function

causes the calling party's lamp on the indication panel to
keep on lighting even if he cancels the call when the
called party is on other line or in Privacy mode.
