• If RETRY_DELAY_s[001] or RETRY_DELAY_s[101] is not set to 0:

• 
  The mobile station shall not send any Origination Message containing a packet data service option¹ or Reconnect Message (with ORIG_IND set to ‘1’) for connecting a packet data service option until the maximum of the system time stored in RETRY_DELAY_s[001] and RETRY_DELAY_s[101].
  
• 
  At the system time stored in RETRY_DELAY_s[001], the mobile station shall reset RETRY_DELAY_s[001] to 0.
  
• 
  At the system time stored in RETRY_DELAY_s[101], the mobile station shall reset RETRY_DELAY_s[101] to 0.
  

– PACA_CANCEL is equal to ‘1’; or

– The mobile station is directed by the user to cancel the PACA call.

• If the PACA state timer expires, the mobile station shall perform the following:

– The mobile station should enter the Update Overhead Information Substate of the System Access State (see 2.6.3) with an origination indication within T_33m seconds to re-originate the PACA call.

– Otherwise, the mobile station shall perform the Mobile Station PACA Cancel Operation as specified in 2.6.2.8.

• If the mobile station supports Data Burst Message transmission, it shall perform the Mobile Station Message Transmission Operation as specified in 2.6.2.6 if directed by the user to transmit a message.

• If the mobile station supports BCMC operation, it shall perform the procedures as specified in 2.6.13.

• If RETRY_DELAY_s[100] or RETRY_DELAY_s[101] is not set to 0:

• 
  The mobile station shall not send any Short Data Burst (see [30], [42]) until the maximum of the system time stored in RETRY_DELAY_s[100] and RETRY_DELAY_s[101].
  
• 
  At the system time stored in RETRY_DELAY_s[100], the mobile station shall reset RETRY_DELAY_s[100] to 0.
  
• 
  At the system time stored in RETRY_DELAY_s[101], the mobile station shall reset RETRY_DELAY_s[101] to 0.
