Huawei OptiX OSN 8800 OTN Tributary Board TN5M2TOG01 02317420

Basic function

TOG converts signals as follows:

• 8 x GE<->8 x ODU0
• 8 x GE<->4 x ODU1

Client-side service type

GE: Ethernet service at a rate of 1.25 Gbit/s. Supports GE optical signals and GE electrical signals.

NOTE:

The TOG board supports GE optical signals and electrical signals. For GE electrical signal transmission, it is recommended that the board be equipped with at most two GE electrical modules to facilitate fiber routing.

Cross-connect capabilities

OptiX OSN 8800: Supports the cross-connection of eight channels of ODU0 signals between the TOG board and the cross-connect board through the backplane.

OptiX OSN 6800: Supports the cross-connection of four channels of ODU1 signals between the TOG board and the cross-connect board through the backplane.

OptiX OSN 3800: Supports the grooming of four ODU1 signals from one board of the mesh group (consisting of four boards) to the other three boards belonging to the mesh group.

OTN function

• Supports the OTN frame format and overhead processing defined in the ITU-T G.709. The mapping process is compliant with ITU-T G.709.
• Supports PM functions for ODU1/ODU0.

Alarms and performance events monitoring

• Monitors BIP8 bytes (Bursty mode) to help locate line failures.
• Monitors OTN alarms and performance events.
• Monitors parameters such as the bias current, temperature, and optical power of the laser.
• Supports the remote monitoring (RMON) of Ethernet services.

NOTE:

The TOG board supports remote monitoring (RMON) only at the receive end .

ALS function

Supports the ALS function on the client side.

PRBS test function

Not supported.

LPT function

Supported

Test frame

Not supported.

Latency measurement

Not supported

IEEE 1588v2

Supports the TC, TC+OC, BC, and OC modes when the client service is GE multiplexed using the GFP-T procedure (the service type is displayed as GE(GFP-T) on the U2000).

NOTE:

The TOG board supports only two channels IEEE 1588v2 signals.

Physical clock

When receiving GE(GFP-T) services on the client side, the board can support synchronous Ethernet processing instead of synchronous Ethernet transparent transmission.

When receiving GE(TTT-GMP) services on the client side, the board can support synchronous Ethernet transparent transmission instead of synchronous Ethernet processing.

Electrical-layer ASON

Supported

Protection scheme

• Supports ODUk SNCP.
• Supports client 1+1 protection.

Ethernet service mapping mode

Supports encapsulation of GE services in GE(GFP-T) or GE(TTT-GMP).
