In OptiX OSN 8800 T64 Enhanced Subrack/OptiX OSN 8800 T32 Enhanced Subrack/OptiX OSN 8800 T16 Subrack, NS4 single board supports line mode and trunk mode. When working in line mode, the OptiX OSN 8800 T64 Enhanced Subrack must be configured with USXH+UXCT veneer; the OptiX OSN 8800 T32 Enhanced Subrack must be configured with UXCH/UXCM veneer; and the OptiX OSN 8800 T16 Subrack must be configured with TN16UXCM veneer.
In the OptiX OSN 8800 T64 Enhanced Subrack/OptiX OSN 8800 T32 Enhanced Subrack/OptiX OSN 8800 T32 General Purpose Subrack/OptiX OSN 8800 T16 Subrack, the NS4 veneer boards support both Line Mode and Trunk Mode. When working in line mode, the OptiX OSN 8800 T64 enhanced subrack must be configured with the USXH+UXCT veneer; the OptiX OSN 8800 T32 enhanced subrack/OptiX OSN 8800 T32 general-purpose subrack must be configured with the UXCH/UXCM veneer; and the OptiX OSN 8800 T16 subrack must be configured with the TN16UXCM veneer The following are some examples of how the UXCH/UXCM veneer must be configured.
The TN56NS4 supports line mode on the OptiX OSN 8800 T32 Universal Subrack only if the "OptiX OSN 8800 T32 Universal Subrack Supports 100G Line Card Capability License" is configured.

TN54NS4/TN56NS4/TN57NS4/TN58NS4: The "Single Board Mode" of this application scenario needs to be set to "Electric Relay Mode" or "Optical Relay Mode". For optical-layer ASON and electrical-layer ASON applications, setting "optical relay mode" and "electrical relay mode" has no effect on the system; for non-ASON applications, only setting "optical relay mode" or "electrical relay mode" has no effect on the system; for non-ASON applications, only setting "optical relay mode" or "electrical relay mode" has no effect on the system. For non-ASON applications, only "Optical Relay Mode" can be set for end-to-end management.
NS4 single board consists of WDM optical module, OTN processing module, control and communication module, and power module.
The functional block diagram of NS4 single board is shown in Figure 1.
The signal flow direction of NS4 single board can be divided into transmit direction and receive direction, i.e., NS4 single board from the backplane to the WDM side is the transmit direction, and vice versa is the receive direction.
The OTN processing module receives the ODUk electrical signals dispatched from the cross-board via the backplane, and completes the operations of OTN framing and FEC coding processing within this module, and outputs one OTU4 signal.
The OTU4 signal is sent to the WDM optical module, and after E/O conversion, the OTU4 optical signal conforming to the DWDM standard wavelength recommended by ITU-T G.694.1 is sent and output from the "OUT" optical port.
The WDM-side optical module receives one OTU4 optical signal from the WDM-side at the "IN" port, which conforms to the DWDM standard wavelength recommended by ITU-T G.694.1, and completes the O/E conversion.
The O/E-converted signal enters the OTN processing module, completes the operations of OTU4 framing and FEC decoding within the module, and outputs the ODUk signal to the backplane for cross-scheduling.
Figure 2 Functional Block Diagram of NS4 Single Board (Relay Mode)
TN58NS4 single board realizes the relaying of 1 channel optical signal, sending and receiving OTU4 optical signals whose wavelengths at both ends are in accordance with the DWDM standard wavelengths recommended by ITU-T G.694.1. The optical receiver module receives the optical signal to be relayed by the "IN" optical port and completes the O/E conversion. The signal is decoded, overhead processed and encoded by the electrical relay module, in which the shaping, regeneration, retiming and encapsulation into OTN frame signal format are completed based on the electrical signal. The encoded signals are sent to the optical transmitter module, which undergoes E/O conversion and sends OTU4 optical signals conforming to the DWDM standard wavelengths recommended by ITU-T G.694.1. The converted optical signal is output from the "OUT" optical port.
The module consists of a WDM-side receiving and transmitting section.
Module includes OTN processing module and crossover module.
Completes OTU4 framing, OTU4 overhead processing, FEC encoding and decoding processing.
Realizes the mutual scheduling of service telecommunication signals between the WDM side signals of this single board through the backplane, and the crossover board.
Converts the DC power supplied by the backplane into the power required by each module of the single board.
