Fast Select Request is a Public Packet Switched Network PPSN optional per-call 
feature that allows user data to be included in the originating call request

FEATURE OPERATION:
The Fast Select Request service permits the calling DTE to send up to 128 octets
of user data in X.25 call setup packets.  The service can be provided 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.
