Installation of extra key panel
DBY 419 01
DBC 422 can have maximum one extra key panel.
DBC 425 can have maximum four extra key panels.
The keys can be used as Dial-by-function keys and Monitoring keys. It is
also possible to assign functions (call back, free on second etc.) on these
keys but it is not recommended because when a user logs on to a phone
without the extra key panel, this function will not be available.
