2. NPIC PERSONNEL INVOLVED IN HANDLING SUCH TRAFFIC ARE
REGULARLY ON DUTY 24 HOURS DAILY, EXCEPT WEEKENDS. IF A MISSION
IS AIRBORNE OR THE TELEMETRY IS BEING PROCESSED, SELECTED PERSONNEL
ARE "ON CALL" ON WEEKENDS WITH A MINIMUM OF ADVANCED WARNING.

OVERTIME AT A MINIMUM, AND TO OBVIATE THE NEED FOR THE NPIC
STANDBY PERSONNEL TO WAIT FOR EXTENDED PERIODS OF TIME FOR
,dvancs C,'ry
ALERTMENT THAT THERE WILL BE A DATA LINK TRANSMISSION. THIS MAY
ALSO ELIMINATE MISUNDERSTANDINGS AND DELAYS OCCASIONED IN THE PAST
BY VIRTUE OF CURRENT OPERATING PROCEDURES. NPIC OBVIOUSLY IS
AWARE THAT EXTENUATING CIRCUMSTANCES MAY CALL FOR SCHEDULE
DEVIATIONS AS IT MAY BE IMPOSSIBLE FOR YOU TO PROCESS THE
INFORMATION MORE EXPEDITIOUSLY. ON THE OTHER HAND, WE WOULD HOPE
THAT YOU AND YOUR TERMINAL STATIONS WILL UNDERSTAND THAT THE CENTER
CAN HAVE MAINTENANCE PROBLEMS WHEN YOU ARE READY TO TRANSMIT TO THE
NPIC. WE WILL, HOWEVER, ENSURE THAT PERSONNEL ARE ON DUTY UNTIL ALL
REQUIRED TRAFFIC HAS BEEN TRANSMITTED.
4. AFTER YOU HAVE HAD AN OPPORTUNITY TO CONSIDER THIS
PROBLEM, IT MAY BE NECESSARY TO CALL FOR A MEETING, AT A MUTUALLY
CONVENIENT TIME, IN ORDER TO DEVELOP A MORE EFFECTIVE, EFFICIENT,
AND LESS COSTLY PROCEDURE.
