at stations that may be otherwise restricted from dialing. All 80 System Speed Dial bins
functionally override a station COS. This capability allows easy adaptation in applications
where restriction is required. The System Speed Dial Emergency Number function is
further partitioned by station COS. Stations assigned COS 0-5 have access to all 80 System
Speed Dial bins, Stations assigned COS 6 have access to System Speed Dial bin (20-39)
only, and COS 7 Stations have no access to System Speed Dial. In all cases, stations that
have access to System Speed Dial can override restrictions that have been established for
manually dialed calls for emergency numbers. Since the System Speed and Emergency
Numbers are controlled by the system administrator, via system programming, certain
stations may be allowed to use these pre-programmed numbers for business purposes
only, while restricting other unauthorized or personal calls.
