13.7 TCP/IP and OSI Networking
ONS 15454 DCN communication is based on the TCP/IP protocol suite. However, ONS 15454 SDH
nodes 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 13-10 shows the protocols and mediation processes that are involved when
TCP/IP-based NEs are networked with OSI-based NEs.
