22.7 TCP/IP and OSI Networking
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/MSTP
scenarios are provided in the following sections.
In OSI/MSTP Scenario 1 (
), an SDCC or RS-DCC carries an OC-N signal from an
OSI-based third party NE to an TXP/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 / TXPP_MR_2.5 (when equipped with OCn-N SFPs)
•
TXP_MR_10G / TXP_MR_10E (when the client is configured as OC192)
•
MXP_2.5_10G and MXP_2.5_10E
