Every ONS 15454 requires a unique, valid IP address.  The CTC application utilizes TCP/IP to 
communicate with nodes in the ONS 15454 network, which requires each node to have a unique 
IP address.  The node’s IP address is equivalent to a terminal identification (TID) number. 
 
ONS 15454s can be connected in many different ways within an IP environment: 
 

    They can be connected to LANs through direct connections or a router. 

 
    IP subnetting can create ONS 15454 node groups, which allow you to provision non-data 

communications channel (DCC) connected nodes in a network. 

 
    Different IP functions and protocols can be used to achieve specific network goals.  For 

example, Proxy Address Resolution Protocol (ARP) enables one LAN-connected ONS 
15454 to serve as a gateway for ONS 15454s that are not connected to the LAN. 

 
    You can create static routes to enable connections among multiple CTC sessions with 

ONS 15454 nodes that reside on the same subnet but have different destination IP 
addresses.
