Huawei Boards TN58NS4 OTN Line Unit TN58NS4T65 03031KNT

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

1. Supports the OTU4 interface on the WDM side.
2. Supports the OTN frame format and overhead processing by referring to the ITU-T G.709.
3. OTU4 layer: supports the SM function.
4. ODUk (k=0, 1, 2, 3, 4, flex) layer: supports the PM and TCM function, and PM and TCM non-intrusive monitoring functions.NOTE:

Only the TN56NS4/TN57NS4/TN58NS4 board supports TCM and TCM non-intrusive monitoring of the ODUflex layer.

WDM specification

Supports ITU-T G.694.1-compliant DWDM specifications.

Tunable wavelength function

The board can tune the optical signal output on the WDM side within the range of 80 wavelengths in C-band with the channel spacing of 50 GHz.

ESC function

Supported

PRBS function

Supports the PRBS function on the WDM side.

LPT function

Not supported

FEC coding

TN54NS4: Supports HFEC and SDFEC on the WDM side.

TN56NS4: Supports SDFEC on the WDM side.

TN57NS4: Supports HFEC and SDFEC2 on the WDM side.

TN58NS4: Supports SDFEC2 on the WDM side.

NOTE:

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

Alarms and performance events monitoring

1. Monitors BIP8 bytes (Bursty mode) to help locate line failures.
2. Monitors parameters such as the bias current, temperature, and optical power of the laser.
3. Monitors OTN alarms and performance events.

Regeneration board

The WDM-side signals from an NS4 board can be regenerated by another NS4 board or an LTX board of the same type. For example,

The type of the TN54NS4T01 board is T01, and the TN54NS4T01 board can be regenerated by other NS4 and LTX boards of the T01 type, such as TN54NS4T01, TN57NS4T01, TN11LTXT01, and TN12LTXT01.

ALS function

Not supported

Latency measurement

1. TN54NS4: not supported.
2. TN56NS4/TN57NS4: supports the PM Latency measurement.
3. TN58NS4: supports the PM and TCM Latency measurement.

Test frame

Not supported

IEEE 1588v2

Not supported

Physical clock

Not supported

Optical-layer ASON

Supported

Electrical-layer ASON

Supported

Protection scheme

1. Supports ODUk SNCP.
2. Supports intra-board 1+1 protection (when working with the OLP/DCP/QCP board).
3. Supports tributary SNCP protection.
4. Supports ODUk SPRing protection.

NOTE:

When the cross-connect granularity is ODUflex, the board does not support tributary SNCP protection and ODUk SPRing protection.
