INTRODUCTION
 represents a block diagram example of CCIS Networking via IP [C-163] when an IPTRK circuit card
in Node A is connected to the IPTRKs of Node B and C (Point-to-Multipoint connection). For more detailed
information, see 
Figure 1-4   Block Diagram - CCIS Networking via IP [Point-to-Multipoint Connection]
Note:
As shown, an IPTRK circuit card, accommodated in a node, can be connected to the IPTRK circuit cards
of multiple nodes, thus achieving Point-to-Multipoint connection.
