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.
NEs are networked with OSI-based NEs.
