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. For detailed information about OSI protocols, processes, and scenarios, refer to the
“Management Network Connectivity” chapter in the ONS 15454 Reference Manual. OSI/MultiService
Transport Platform (MSTP) scenarios are provided in the following sections.
In OSI/MSTP Scenario 1 (Figure 15-27), an SDCC or RS-DCC carries an OC-N/STM-N signal from an
OSI-based third-party NE to a transponder (TXP) or muxponder (MXP) card on an ONS NE. It is carried
by GCC to a TXP/MXP card on another MSTP NE and then by SDCC or RS-DCC to a second third-party
NE. This scenario requires TXPs/MXPs whose client interfaces can be provisioned in section or line
termination mode. These include:
• TXP_MR_2.5 and TXPP_MR_2.5 (when equipped with OC-N/STM-N SFPs)
• TXP_MR_10G and TXP_MR_10E (when the client is configured as OC-192/STM-64)
• MXP_2.5_10G and MXP_2.5_10E
