2.2.2.  Credit Control Response Message

   Credit Control Response Messages are sent by routers to report the
   current credit window for a destination.  A Credit Control Response
   Message sent by a router MUST contain one or more Credit Window
   Status Data Items as defined in Section 2.3.4.  Specific receive
   processing associated with the Credit Window Status Data Item is
   provided in Section 2.3.4.

   Credit Control Response Messages sent by modems MUST contain one or
   more Credit Window Grant Data Items.  A Data Item for every Credit
   Window Request Data Item contained in the corresponding Credit
   Control Message received by the modem MUST be included.  Each Credit
   Window Grant Data Item MAY provide zero or more additional credits
   based on the modem's transmission or local queue availability.
   Specific receive processing associated with each Credit Window Grant
   Data Item is provided in Section 2.3.3.

   The Message Type value in the DLEP Message Header is set to 18.
