9.2.1.1. HFA Logon 
Enter the DAR for mobile HFA logon.
Then the user is asked to enter his home number (terminate with #)
and his PIN (terminate with #).
Display says “MOBILE HFA LOGON STARTED”. If all checks run ok
soon his own display on the home phone is displayed. As it he was really
at home.
If the checks do not run OK (wrong password, wrong home number, missing
attributes, ...) the rejection is shown on display.
- Mobility session (home phone physical extended)
-
The home phone displays “Forced Logoff - Cancel mobility?” and is not usable, even not for fire brigade or other emergency calls. The only possible action is to cancel the mobility. But this action is protected by password (phone password - not the same as mobility password).
- Shared Desk Area (No physical home phone)
-
If the home phone does not exist physically nothing can be displayed on the home. No cancellation from home phone is possible.
