UAT Schedule adjustment• All sites are affected due to this change.• SFC needs some measurement before parameter

change,so that all SFC carrier will stop 1 day.

• Basic policy– Ku-Band and C-Band UAT goes independently.– Both C and Ku band changes takes a day.– When stopping the carrier and UAT , please call to YSCC.

• I will prepare the table including frequency, symbol rate and carrier type information, then I will send the web location of it to you using “ai3-ix@ai3.net”.

Ku-Band UAT Time Schedule• Related Site

– NAIST, ITB, AIT• Procedure Outline

• AIT -> NAIST and NAIST->AIT changes• ITB -> NAIST and NAIST receive change in parallel.

• Let’s fix the changing date (10/10)– 10/10 11:00~13:00 JST (9:00~11:00 @AIT)

• AIT will stop and start to transmit after parameter change.• NAIST will confirm the receiving carriers.• NAIST will stop and start to transmit after parameter change.• AIT will confirm the receiving carriers.

– 10/10 16:00~18:00 JST (14:00~16:00@ITB)• ITB will stop and start to transmit after parameter change.• NAIST will confirm the receiving carriers.

C-Band UAT Time Schedule• Related Site

– SFC , PH , Laos , All UDL RO site , MY , VN , SG• Procedure Outline

• PH->SFC,SFC->PH and Laos->SFC, SFC->Laos change. (Step-1)• All SFC carriers stop and do some measurement. (Step-2)• All SFC carriers start to transmit after parameter changes. (Step-3)

• Let’s fix the SFC measurement date (11/14)– 11/14 10:00~12:00 JST (8:00~10:00@Laos ; 9:00~11:00@PH)

• PH->SFC and Laos->SFC will stop and start to transmit after parameters change.• SFC confirm the receiving carriers.• SFC->PH and SFC->Laos will stop and start to transmit after parameters change.• PH, Laos will confirm the receiving carriers.

– 11/14 13:00~17:00 JST (11:00~15:00@Laos,VN ; 12:00~16:00@SG,MY,PH)

• SFC will stop all carriers, and do some measurement and transmit carriers after parameter change.

– 11/14 18:00~ JST (16:00~@Laos,VN ; 17:00~@SG,MY,PH)PH,Laos, MY, VN, SG, all RO site will confirm the receiving SFC carriers.
