ABSTRACT:
The present administration arrangement disables any idle system apparatus which would be affected by the administration changes being made. In the station administration mode once the selected station is idle it is held in a forced idle state until administration is completed. During the system administration mode all idle stations are held in the forced idle state and all idle central office lines are placed in a forced busy state until system administration is completed. Station visual and audible signals indicate the administration status to system users. At the conclusion of administration, any forced idle stations and forced busy central office lines are returned to the normal state.
