1007 Fast Select Acceptance - Packet

Fast Select Acceptance is an optional feature which works in conjunction with 
the Fast Select Request facility.  This capability allows the called Data 
Terminal Equipment (DTE) to receive user data in the call setup packet.  The 
terminating (called) DTE must be subscribed to the Fast Select Acceptance 
facility to receive Fast Select call.  If the terminating DTE does not 
subscribe to Fast Select Acceptance, the Data Circuit Terminal Equipment (DCE) 
would respond to the Fast Select Request call of the origination DTE with a 
clear indication packet, indicating that Fast Select Acceptance is not 
subscribed to.

FEATURE OPERATION:
The Fast Select Acceptance feature permits the calling DTE to send up to 128 
octets of user data in the call setup packet to a called DTE subscribed to the 
Fast Select Acceptance feature.  The service is available in a restricted and 
unrestricted mode.  In the unrestricted mode the called DTE has an option to 
accept the call request and exchange data packets.  In the restricted mode the 
call request is cleared and only data associated with call setup and clearing is
exchanged.

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:
1. This feature is defined in the CCITT X.25, X.75 and X.75' utilities
   as always required.

2. The PPSN Access Concentrator (AC) should support X.25 direct access and
   dial-in interfaces.

3. The ISDN Packet Handling Facility should support the X.25 direct
   access interface to the user and the X.75' interface to the PPSN.

4. References:
