Huawei OptiX OSN 8800 Line Service Processing Board TN52NS3T01

Basic function

NS3 converts signals as follows:

• TN11NS3:
  • 4xODU2<->1xOTU3/OTU3e
  • 4xODU2e<->1xOTU3e
• TN52NS3:
  • 32xODU0/16xODU1/4xODU2<->1xOTU3/OTU3e
  • 4xODU2e<->1xOTU3e
• TN54NS3/TN55NS3:
  • 32xODU0/16xODU1/4xODU2<->1xOTU3/OTU3e
  • 4xODU2e<->1xOTU3e
  • 1xODU3<->1xOTU3
• TN56NS3:
  • 32xODU0/32xODUflex/16xODU1/4xODU2<->1xOTU3/OTU3e
  • 4xODU2e<->1xOTU3e
  • 1xODU3<->1xOTU3
  • 16xSTM-16/4xSTM-64<->1xOTU3/OTU3e

The TN52NS3/TN54NS3/TN55NS3 board supports hybrid transmission of ODU0/ODU1/ODU2/ODU2e signals. The TN56NS3 board supports hybrid transmission of ODU0/ODU1/ODU2/ODU2e/ODUflex/VC-4 signals. When the mixed signals contain an ODU2e signal, they must be mapped into an OTU3e signal.

The TN11NS3/TN52NS3/TN54NS3 board supports dispersion compensation for signals received on the WDM side.

Cross-connect capabilities

Supports cross-connections with cross-connect boards.

OptiX OSN 8800:

• TN52NS3: 32xODU0/16xODU1/4xODU2/4xODU2e
• TN54NS3/TN55NS3: 32xODU0/16xODU1/4xODU2/4xODU2e/1xODU3

TN56NS3: 32xODU0/32xODUflex/16xODU1/4xODU2/4xODU2e/1xODU3/256xVC-4

NOTE:

When the TN56NS3 board is installed in an OptiX OSN 8800 T64 subrack, the board supports a maximum of 128 VC-4 services. This limit does not apply when the board is installed in an OptiX OSN 8800 T32/T16 subrack.

OptiX OSN 6800:

• TN11NS3: 4xODU2/4xODU2e
• TN52NS3: 16xODU1/4xODU2/4xODU2e

OTN function

• Supports the OTU3/OTU3e interface on the WDM side.
• Supports the OTN frame format and overhead processing by referring to the ITU-T G.709.
• OTU3 layer: supports the SM function.
• ODUk (k=0, 1, 2, 3, flex) layer: supports the PM and TCM function, and PM and TCM non-intrusive monitoring functions.

NOTE:

Only the TN56NS3 board supports TCM and TCM non-intrusive monitoring of the ODU0 and ODUflex layer.

SDH service processing

Supports the VC-12 services, VC-3 services, VC-4 services, VC-4-4c concatenation services, VC-4-16c concatenation services, and VC-4-64c concatenation services.

SDH overhead processing

Only the TN56NS3 board supports the following functions:

• Processes the section overheads of STM-16/STM-64 signals.
• Supports the transparent transmission and termination of path overheads.
• Supports the setting and query of the J0, J1, and C2 bytes.

NOTE:

The TN56NS3 board supports D4–D12 overhead processing. It does not support D1–D3 overhead processing.

WDM specification

FEC coding

TN11NS3/TN52NS3:

• Supports ITU-T G.709-compliant forward error correction (FEC) on the WDM side.
• Supports ITU-T G.975.1-compliant advanced forward error correction (AFEC) on the WDM side.

TN54NS3:

• Supports ITU-T G.709-compliant forward error correction (FEC) on the WDM side.
• Supports ITU-T G.975.1-compliant AFEC-2 on the WDM side.

TN55NS3/TN56NS3:

• Supports HFEC.

NOTE:

Boards that use different FEC modes cannot interconnect with each other.

Alarms and performance events monitoring

• Monitors BIP8 bytes (Poisson mode or 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.

• Supports CD and PMD performance monitoring.
• Monitors B1 bytes to help locate faults.
• Monitors B2 bytes to help locate faults.

NOTE:

Only the TN54NS3 supports Poisson mode.

Only the TN55NS3/TN56NS3 board supports CD and PMD performance monitoring.

Only the TN56NS3 board supports B1/B2 byte monitoring.

Regeneration board
