You can lock stations using a Time of Day (TOD) schedule.

To engage the TOD station lock or unlock, you do not have to dial the station lock or unlock FAC.

When the TOD feature activates the automatic station lock, the station uses the COR assigned to the station lock feature for call processing. The COR used is the same for manual station locks.

The TOD lock or unlock feature does not update displays automatically because the system would have to scan through all stations to find the ones to update.

The TOD Station Lock feature works as follows:

• If the station is equipped with a display and the station invokes a transaction which is denied by the Station Lock COR, the system displays Time of Day Station Locked. Whenever the station is within a TOD Lock interval and the special dial tone is administered, the user hears a special dial tone instead of the normal dial tone.

• For analog stations or without a display, the user hears a special dial tone. The special dial tone has to be administered, and the user hears the special dial tone when the station is off hook.

After a station is locked by TOD, it can be unlocked from any other station if the Feature Access Code (FAC) or button is used. You have to also know the Station Security Code, and that the Manual-unlock allowed? field on the Time of Day Station Lock Table screen is set to y.

Once a station has been unlocked during a TOD lock interval, the station remains unlocked until next station lock interval becomes effective.

If the station was locked by TOD and by Manual Lock, an unlock procedure will unlock the Manual Lock as well as the TOD Lock (“Manual-unlock allowed?” field on the Time of Day Station Lock Table screen is set to y).

The TOD feature does not unlock a manually locked station.
