ONS 15454 DCN communication is based on the TCP/IP protocol suite. However, ONS 15454s can also

be networked with equipment that uses the OSI protocol suite. While TCP/IP and OSI protocols are not

directly compatible, they do have the same objectives and occupy similar layers of the OSI reference

model. Table 13-7 shows the protocols and mediation processes that are involved when TCP/IP-based

NEs are networked with OSI-based NEs.
