Huawei OSN 8800 OTN Tributary Board TN55TQX 02310EKA

Function and Feature

Description

Basic function

TQX converts signals as follows:

1. 4xFC800/10GE LAN/10GE WAN/STM-64/OC-192/OTU2<->4xODU2
2. 4xFC1200/10GE LAN/OTU2e<->4xODU2e.
3. 4xFC800<->4xODUflex

Client-side service type

STM-64/OC-192: SDH/SONET service at a rate of 9.95 Gbit/s

10GE LAN: Ethernet service at a rate of 10.31 Gbit/s

10GE WAN: Ethernet service at a rate of 9.95 Gbit/s

OTU2: OTN service at a rate of 10.71 Gbit/s

OTU2e: OTN service at a rate of 11.1 Gbit/s

FC800: SAN service at a rate of 8.5 Gbit/s

FC1200: SAN service at a rate of 10.51 Gbit/s

NOTE:

Only the TN53TQX/TN55TQX supports FC800 and FC1200 services.

Only the TN52TQX/TN53TQX/TN55TQX supports OTU2 and OTU2e services.

The processing of the 10GE WAN service and the STM-64 service is the same. Therefore, For the TN11TQX/ TN52TQX, when the 10GE WAN service is transmitted, you can configure it as the STM-64 service on the U2000.

Cross-connect capabilities

Supports the cross-connection of four ODU2/ODU2e/ODUflex signals between the TQX and the cross-connect board through the backplane.

NOTE:

The cross-connection of ODUflex signals is supported only by the TN55TQX board.

OTN function

1. Supports overhead processing by referring to the ITU-T G.709. The mapping process is compliant with ITU-T G.709 and G.Sup43.
2. Supports PM function for ODU2.
3. Supports SM and TCM function when the TN52TQX, TN53TQX and TN55TQX receives OTN services.

ESC function

Supported by the TN52TQX/TN53TQX/TN55TQX when the client-side service type is OTU2 or OTU2e.

FEC coding

Supports ITU-T G.709-compliant forward error correction (FEC) on the client side, only when the service type is OTU2/OTU2e.

Alarm and performance event monitoring

1. Monitors BIP8 bytes (Bursty mode) to help locate line failures.
2. Monitors B1 bytes to help locate faults.
3. Monitors parameters such as the bias current, temperature, and optical power of the laser.
4. Monitors OTN alarms and performance events.
5. Supports the remote monitoring (RMON) of Ethernet services (10GE LAN).

ALS function

Supports the ALS function on the client side when client services are non-OTN services.

PRBS test function

Supports the PRBS function on the client side.

NOTE:

The PRBS function on the client side is supported only when the client-side service type is STM-64/OC-192, OTU2 or OTU2e.

LPT function

The board supports the LPT function only when the client-side service type is 10GE LAN.

Test frame

Supports the test frame function when the client-side service type is 10GE LAN and the Port mapping is MAC Transparent Mapping (10.7 G).

Latency measurement

The TN53TQX/TN55TQX (standard mode) board supports latency measurement. The bidirectional latency at the ODUk layer between two tributary boards supporting the latency measurement function can be measured, and the latency data is displayed on the U2000.

NOTE:

This function is not supported when the client-side service type is OTU2/OTU2e.

IEEE 1588v2

The TN55TQX board supports the TC, TC+OC, BC, and OC modes when the client-side service type is 10GE LAN and the Port Mapping is MAC Transparent Mapping (10.7 G).

Physical clock

TN55TQX:

1. When the board receives 10GE LAN services and the port mapping is Bit Transparent Mapping (11.1 G) on its client side, the board can support synchronous Ethernet transparent transmission instead of synchronous Ethernet processing.
2. When the board receives 10GE LAN services and the port mapping is MAC Transparent Mapping (10.7 G) on its client side, the board can support synchronous Ethernet processing instead of synchronous Ethernet transparent transmission.

TN52TQX/TN53TQX: When the board receives 10GE LAN services and the port mapping is Bit Transparent Mapping (11.1 G) on its client side, the board can support synchronous Ethernet transparent transmission instead of synchronous Ethernet processing.

Electrical-layer ASON

Supported by the TN52TQX/TN53TQX/TN55TQX

Protection scheme

1. Supports ODUk SNCP.
2. Supports client 1+1 protection.
3. Supports tributary SNCP protection.

NOTE:

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

NOTE:

When the board receives OTN services, SDH/SONET services, and 10GE WAN services the board supports tributary SNCP protection.

Ethernet service mapping mode

Bit Transparent Mapping(11.1G), MAC Transparent Mapping(10.7G)

Port MTU

The value ranges from 1518 to 9600, in bytes. That is, the maximum size of the supported Jumbo frame is 9600 bytes.

NOTE:

when Port Mapping is set to Bit Transparent Mapping(11.1G), Maximum Packet Length is unavailable on the U2000.
