ONS 15310-MA SDH DCN communication is based on the TCP/IP protocol suite. However,

ONS 15310-MA 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 8-7 shows the protocols that are involved when

TCP/IP-based NEs are networked with OSI-based NEs.
