10.41.5.2. Key assignment 
OpenStage telephones have fixed keys. For this reason, the correct
standard key layouts must be assigned. The keys 1-8 must correspond to
the illustrated examples. The variable keys start from key 9 onwards.
Therefore, the appropriate key layout for every OpenStage terminal is
available in AMO TAPRO (parameter DIGTYP).
SHIFT key
A SHIFT key can also be configured on OpenStage terminals (previously
this was only possible on key modules). This is achieved with the AMO
TAPRO or via the Service menu on the terminal.
CHANGE-TAPRO:STNO=<station number>, KYxx=SHIFT;
IMPORTANT:
xx must be greater than 08 since the first 8 keys are fixed. Only key 9
and onwards can be freely assigned.
When the SHIFT key is pressed on an optiPoint key module, the same action is performed
on
all other key modules. In other words, the SHIFT level is also activated on the second
and
fourth key modules.
This is not the case on OpenStage telephones and key modules. In this case, the SHIFT
level
is only activated on the telephone/key module on which the SHIFT key was pressed.
