4.2.6    C̲C̲I̲S̲ ̲L̲o̲w̲ ̲L̲e̲v̲e̲l̲ ̲P̲r̲o̲t̲o̲c̲o̲l̲s̲ ̲(̲C̲L̲P̲)̲



4.2.6.1  F̲u̲n̲c̲t̲i̲o̲n̲a̲l̲ ̲S̲p̲e̲c̲i̲f̲i̲c̲a̲t̲i̲o̲n̲

         The CLP package is responsible for data communication
         between the CR80 and the GRTS software in the DN355DN6678
         front-end processor on the CCIS side.

         CLP is implemented in the CR80 LTU and the CLP SW therefore
         has to be down-line loaded from the CR80 memory during
         initialization of the LTU.

         CLP communicates with the GRTS using the following
         three ypes of subsegments:

         - S̲e̲r̲v̲i̲c̲e̲ ̲M̲e̲s̲s̲a̲g̲e̲s̲  for opening and closing the line

         - C̲o̲n̲t̲r̲o̲l̲ ̲M̲e̲s̲s̲a̲g̲e̲s̲  for delivery of passwords and other
         
           control data.

         - I̲n̲f̲o̲r̲m̲a̲t̲i̲o̲n̲ ̲M̲e̲s̲s̲a̲g̲e̲s̲  used during the transmission
           of data segments 

         In this context th term "messages" means the various
         subsegment types sent between the CLP and GRTS including
         header and trailer characters.

         Due to the half-duplex nature of the communication
         link the sets of messages sent from the two sides are
         not symmetrical. Terefore, a description of the possible
         messages sent from either side of the link is given
         in Figure 4.2.6.1-1 and 4.2.6.1-2.
