Trunk keys (on multi-line phones only)
Some of the programmable keys on multi-line phones can be set up as trunk keys. Each key that
is assigned the function "line" is handled as a line. This means up to three lines can be configured.
A distinction is drawn here between primary, secondary and phantom lines. Each of these line
types can be used on a private or shared basis.
Primary line
All multi-line telephones have a primary line. This line can be reached in the usual manner via your
public phone number. Incoming calls are signalled on this line.
Secondary line
The secondary line on your phone is used as a primary line by another subscriber of the line trunk
group. Your primary line, which is configured on another telephone in the line trunk group, simul-
taneously functions as the secondary line on that telephone.
Phantom line
Phantom lines are not used as primary lines by any telephones in the line trunk group. Phantom
lines are established when the number of lines provided by a communications system exceeds the
number of available telephones.

To avoid conflict between individual multi-line phones, the functions "Do not disturb" and
"Call forwarding" can only be used for the primary line.
