Function and feature	Description
Basic function	NS4 converts signals as follows:
	80xODU0/80xODUflex/40xODU1/10xODU2/10xODU2e/2xODU3/1xODU4<->1xOTU4
	Supports mixed transmission of ODU0, ODU1, ODUflex, ODU2, ODU2e, and ODU3 signals.
Cross-connect capabilities	Supports the cross-connection of 80 channels of ODU0/ODUflex signals or 40 channels of ODU1 signals or ten channels of ODU2/ODU2e signals or two channels of ODU3 signals or one channel of ODU4 signals between the NS4 and the cross-connect board.
OTN function	Supports the OTU4 interface on the WDM side.
	Supports the OTN frame format and overhead processing by referring to the ITU-T G.709.
	OTU4 layer: supports the SM function.
	ODUk (k=0, 1, 2, 3, 4, flex) layer: supports the PM and TCM function, and PM and TCM non-intrusive monitoring functions.
WDM specification	Supports DWDM specifications.
Tunable wavelength function	The WDM side optical signals can be carried over wavelengths in the extended C band.
	TN96NS4:Supports 50 GHz and 37.5 GHz channel spacing designs. A total of 96 wavelengths can be configured for 50 GHz channel spacing and 128 wavelengths for 37.5 GHz channel spacing.

PRBS function	Supports the PRBS function on the WDM side.
LPT function	Not supported
FEC coding	Supports SDFEC2 on the WDM side.
	NOTE:
	Boards that use different FEC modes cannot interconnect with each other.
Alarms and performance events monitoring	Monitors BIP8 bytes (Bursty mode) to help locate line failures.
	Monitors parameters such as the bias current, temperature, and optical power of the laser.
	Monitors OTN alarms and performance events.
Regeneration board	The WDM-side signals of the TN96NS4T31 board can be regenerated by another TN96NS4T31 board.
	The WDM-side signals of the TN97NS4T31 board can be regenerated by another TN97NS4T31 board.

	Supports intra-board 1+1 protection (when working with the QCP or OLP or DCP board).
	Supports tributary SNCP protection.
	NOTE:
	Only the TN96NS4 board supports intra-board 1+1 protection.
	When the cross-connect granularity is ODUflex, the board does not support tributary SNCP protection.
