When Controlled Restriction is activated through the PMS, the PMS sends a message to Communication Manager to assign one of the following restrictions to the phone in a guest/patient room:
No restriction
Outward restriction
Total restriction
Station-to-station restriction
Termination restriction
Combined outward and termination restriction
Combined outward and station-to-station restriction
Combined termination and station-to-station restriction
The attendant can still set Controlled Restriction for a telephone whether the PMS link is up or down.
