Boards supporting transparent transmission of synchronous Ethernet services

11

The 12LSX, 13LSX, 52TDX, 52TOG, 55TQX, 53TDX, and 55TOX boards support transparent transmission of synchronous Ethernet services when the boards are set to the bit transparent mapping or TTT-GMP mode.

Whether the 52NS2 board supports synchronous Ethernet transparent transmission
The function of synchronous Ethernet transparent transmission depends on tributary boards instead of line boards. The 52NS2 board is a line board.

Yes, the LOG board supports synchronous Ethernet transparent transmission.

Transmission of synchronous Ethernet clock signals on the TN52TDX board
In bit transparent transmission mode, client 10GE LAN services are directly mapped to OTU2 frames. Then the OTU2 frame frequency is increased to transmit signals. The rate is 11.1 Gbit/s, which is higher than the standard rate of OTU2 signals. In this case, the processing clock is the service tracing clock, and the speedup mode is configured for cross-connections, implementing transparent clock transmission.

Methods used to configure the transparent transmission of synchronous Ethernet clock signals on the F2LDGF2 board of OSN 1800
1. For hardware, the TNF2LDGF2 board must be used because the TNF1LDGF2 board does not support the transparent transmission of synchronous Ethernet clock signals. For software, the NE version must be V100R003 or a later version. Versions earlier than V100R003 do not support the TNF2LDGF2 board. A logical board must be added to the F2LDGF2 board. 2. The service type at the GE port must be set to GE (TTT-GMP) on the F2LDGF2 board. On the F2LDGF2 board, TTT-GMP services can better support the transparent transmission of synchronous Ethernet clock signals than GFP-T services. If the original service type is GFP-T, delete the WDM services, set the service type to TTT-GMP, and then reconfigure the WDM services. (The WDM services can also be deactivated and then activated after the service type is changed.) 3. The TNF2LDGF2 board supports GE (TTT-GMP) services only when it works in 2 x AP2 ODU0 mode. Therefore, the working mode of the board must be set to 2 x AP2 ODU0. Suggestions and summary: For details about whether all boards on OptiX OSN 1800 support the processing and transparent transmission of synchronous Ethernet clock signals and the methods used to configure service types, see "Feature Description > Synchronization Features > Synchronous Ethernet Clock > Availability" in the User Guide to OSN 1800 V100R003 or the latest product documentation.

Whether the TN52TDX board can transmit synchronous Ethernet clock signals
The 10GE LAN bit transparent transmission mode can directly map client services into OTU2 frames. Signals are transmitted by increasing the OTU2 frame frequency, and its rate is 11.1 Gbit/s, which is higher than the rate of standard OTU2 signals. In this transmission mode, service clocks are traced as clock sources, the line rate is configured to the speedup mode, and service clocks are transparently transmitted.
