Key Functions
When a featurephone is converted to a key telephone one of the keys becomes
an internal key, a number of keys become line keys, and the remaining keys can
be freely configured in the same way as on the featurephone.
The internal key allows the key telephone to be addressed and used in the same
way as an ordinary internal subscriber, in accordance with the settings in the sub-
scriber configuration.
The maximum number of line keys possible depends on the terminal type.
The key telephone can be set in such a way that an incoming or outgoing call on
a line key is either automatically allocated a KT line or automatically answered, as
the case may be. Depending on the type of terminal the line keys can be provided
with up to 9 priority levels (see the system terminal's Operating Instructions).
Signalling
A call on a KT line is signalled both acoustically and visually. The status of the KT
lines is indicated by LED signalling.
