The NS4 supports the conversion of the following signals:

80xODU0/80xODUflex/40xODU1/10xODU2/10xODU2e/2xODU3/1xODU41xOTU4

Supports mixed transmission of ODU0, ODU1, ODU2, ODU2e, ODUflex, and ODU3.

Supports 80 channels of ODU0/ODUflex or 40 channels of ODU1 or 10 channels of ODU2/ODU2e or 2 channels of ODU3 or 1 channel of ODU4 signals with cross board to realize cross scheduling of services.

• WDM side supports OTU4 interface.
• Adopts ITU-T G.709 recommended frame format and overhead processing.
• OTU4 layer: supports SM function.
• ODUk (k=0, 1, 2, 3, 4, flex) layer: supports PM and TCM functions, non-invasive monitoring functions for PM and TCM.
  Description:

  Only TN56NS4/TN57NS4/TN58NS4 support TCM function of ODUflex layer and non-intervention monitoring function of TCM.

Supports DWDM specifications of ITU-T G.694.1.

Wavelength-side optical signals are adjustable in the 80-wave range at 50 GHz intervals in the C-band.

The WDM side supports the PRBS function.

TN54NS4: HFEC/HFEC2 and SDFEC coding are supported.

TN56NS4: SDFEC coding is supported.

TN57NS4: Supports HFEC and SDFEC2 encoding.

TN58NS4: Supports SDFEC2, HFEC PLUS encoding.

• Provides BIP8 byte monitoring (burst mode) to locate line faults.
• Provides the following monitoring functions: laser bias current monitoring, laser operating temperature monitoring, optical power monitoring, etc.
• Supports OTN performance monitoring and alarm monitoring.

The WDM side signal of NS4 single board can be relayed by other NS4 and LTX single boards of the same type. For example:

• The NS4 single board of type T01 can relay through other NS4 single boards and LTX single boards of type T01. That is, TN54NS4T01 veneer board can relay through TN54NS4, TN57NS4, TN11LTX and TN12LTX veneer boards of type T01.

• TN54NS4: Not supported.
• TN56NS4/TN57NS4: PM delay measurement is supported.
• TN58NS4: Support PM and TCM delay measurement.

• Supports ODUk SNCP protection.
• Supports on-board 1+1 protection (realized with QCP or OLP or DCP single board).
• Supports branch SNCP protection.
• Support ODUk ring network protection.
