Basic functions

Port Working Mode

Supports the following service conversions:

• 1 x OTU4<->1 x ODU4
• 1 x 100GE (Bit Transparent Mapping/ MAC Transparent Mapping)<->1 x ODU4/n x ODUflex (n = (1-80))

Mapping path:

• OTU4<->ODU4
• 100GE<->ODU4
• 100GE<->GFP-F<->ODU4
• 100GE<->GFP-F<->ODUflex

Cross-connect functionality

Supports backplane cross-connections of one ODU4 or n ODUflex (n = (1-80)) signals from/to the cross-connect board.

Service specifications

Service types

100GE: Ethernet service at a rate of 103.125 Gbit/s

OTU4: OTN service at a rate of 111.81 Gbit/s

When 100GE services are received on the client side and mapped into ODUflex, the client equipment must support flow control response.

Service mapping mode

100GE: Bit Transparent Mapping/ MAC Transparent Mapping

Maximum frame length (MFL) for a port

Ranges from 1518 bytes to 9600 bytes.

Protection schemes

Client 1+1 Protection

Supported

ODUk SNCP

Supported

Tributary SNCP

Supported

LPT

Not supported

ALS

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

Synchronization

Synchronous Ethernet

Supports synchronous ethernet processing when 100GE(GFP-F) services are received on the client side.

Supports synchronous ethernet transparent transmission when 100GE(GMP) services are received on the client side.

IEEE 1588v2

Not supported

G.8273.2

Not supported

G.8275.1

Not supported

Maintenance features

Loopbacks

Supports inloops and outloops on the client side.

Pseudo random binary sequence (PRBS) test function

Supports the PRBS test function on the client side only when receiving OTU4 services.

Test frames

Supports this function when receiving 100GE services on the client side.

Delay measurement (DM)

Supports DM. Specifically, the bidirectional delay between two tributary boards supporting DM can be measured, and the delay data is displayed on the NMS.

Alarms and performance events monitoring

• Monitors BIP8 bytes (burst mode) to help locate line failures for 100GE services.
• Monitors OTN alarms and performance events.
• Monitors parameters such as the bias current, temperature, and optical power of the laser.
• Supports Ethernet bandwidth usage of the RMON performance statistics.

OTN Overheads

• Supports overhead processing defined by ITU-T G.709. The service mapping process complies with ITU-T G.709 and G.Sup43.
• ODU4 layer:
  • When the client-side service type is 100GE, supports PM overhead processing.
  • When the client-side service type is OTU4, supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads.
• ODUflex layer: supports PM overhead processing.
• OTU4 layer: supports SM overhead processing.

Outband DCN

Supports ESC communication.

FEC Mode

Supports ITU-T G.709-compliant forward error correction (FEC) encoding on the client side only when receiving OTU4 signals.

Electrical-layer ASON

Supported
