1014 Reverse Charge Acceptance - Packet

Reverse Charge Acceptance is an optional per-call Public Packet Switched Network
(PPSN) subscription feature that allows a call from an originating Data Terminal
Equipment (DTE) to be charged to the terminating DTE.  Upon receiving a reverse
charge indication the incoming DTE may accept or reject the call.

FEATURE OPERATION:
The PPSN Data Circuit Terminating Equipment (DCE) and the ISDN Packet Handling 
Function (PHF) should deliver the reverse charging call request to the called 
DTE/DCE or CPE/PHF only when the interface is configured for reverse charging, 
otherwise the call is cleared.  A Network User Identification (NUI) parameter 
may be signaled in the call accept packet.

TECHNOLOGICAL AND FEATURE INTERACTION CONSIDERATIONS:
1. Reverse billing for the packet charges is allowed by assigning the packet
   feature "Reverse Charge Acceptance" to the ESP's voice grade line circuit
   switched termination on the Packet Switch.

2. The reverse charging acceptance allows the X.25 ESP to accept their end
   users' applicable packet charges on calls that their customers initiate
   with a billing designation of the terminating Data Terminal Equipment
   (DTE).  During the call setup, the originating DTE signals that reverse
   charging is being requested by setting the reverse charging facility field 
   in the call request packet.  This is done on a per call basis.  If the
   terminating DTE subscribes to the reverse charge acceptance service,
   then the terminating DTE will receive the associated call packet with
   the reverse charging field set.  If the terminating customer does not
   subscribe to the reverse charging acceptance service, the call will be
   cleared and the originating DTE will receive a response indicating that
   the reverse charge acceptance is not an acceptable option.
