Huawei OSN 9800 M24, U16, U32, U64, 100G Tributary Service Processing Board
| Function and Features | |
| Basic functions | Supports the following service conversions: |
| 1 x 100GE (Bit Transparent Mapping/MAC Transparent Mapping) <-> 1 x ODU4 | |
| 1 x 100GE (MAC Transparent Mapping) <-> 1 x ODUflex | |
| 1 x 40GE (TTT+GMP)<-> 1 x ODU3 | |
| 1 x OTU4 <-> 1 x ODU4 | |
| Client-side service type | 100GE: Ethernet service at a rate of 103.125 Gbit/s |
| 40GE: Ethernet service at a rate of 40 Gbit/s | |
| OTU4: OTN service at a rate of 111.81 Gbit/s | |
| Cross-connect capabilities | T401: Supports backplane cross-connections of one ODU4/ODU3/ODUflex signal from/to the cross-connect board. |
| T402: Supports backplane cross-connections of two ODU4/ODU3/ODUflex signals from/to the cross-connect board. | |
| T404: Supports backplane cross-connections of four ODU4/ODU3/ODUflex signals from/to the cross-connect board. | |
| OTN functions | Supports overhead processing defined by ITU-T G.709. The service mapping process complies with ITU-T G.709 and G.Sup43. |
| ODUflex layer: supports PM overhead processing. | |
| ODU3 layer: supports PM overhead processing. | |
| 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. | |
| OTU4 layer: supports SM overhead processing. | |
| ESC function | Supported when the client-side service type is OTU4. |
| FEC coding | Supports ITU-T G.709-compliant forward error correction (FEC) when the client-side service type is OTU4. |
| When the client-side service type is 100GE, only RS_FEC coding is supported. | |
| LLDP function | When the client-side service type is 40GE/100GE, the board supports LLDP. |
| NOTE: When interworking with TNU1CTU or TNS1CTU, T401/T402/T404 does not support LLDP. When the service mapping mode is MAC transparent mapping, the LLDP mode of the port is the Receive mode by default. In this case, LLDP packets are not transparently transmitted. | |
| ALS function | Supports the ALS function on the client side when client services are non-OTN services. |
| Test frame | When the client-side service type is 40GE/100GE, the board supports test frame. |
| Latency measurement | When non-OTN services are received on the client side of the board, the PM section latency measurement is supported in the backplane direction (upstream direction). When OTN services are received on the client side of the tributary board, the TCM section latency measurement is supported in the optical port direction (downstream direction). |
| IEEE 1588v2 | When the client-side service type is 100GE(GFP-F), the board supports IEEE 1588v2. |
| ITU-T G.8275.1 | When the client-side service type is 100GE(GFP-F), the board supports ITU-T G.8275.1. |
| ITU-T G.8273.2 | Supports G.8273.2 only in the M24 subrack. |
| Line mode OTN functions and features | Description |
| Basic function | 80 x ODU0/40 x ODU1/10 x ODU2/10 x ODU2e/2 x ODU3/1 x ODU4/80 x ODUflex<->1 x OTU4 |
| OTN functions | Supports the OTU4 interface on the WDM side. |
| Supports the OTN frame format and overhead processing defined in ITU-T G.709. | |
| OTU4 layer: supports SM overhead processing. | |
| ODUk (k = 0, 1, 2, 2e, 3, 4, flex) layer: supports PM and TCM overhead processing, and non-intrusive monitoring of PM and TCM overheads. | |
| PRBS test function | Supports the PRBS function on the WDM side. |
| FEC coding | Supports FEC encoding |
| Latency measurement | The board supports latency measurement in the WDM-side optical port direction (upstream direction). When higher-order ODU4 cross-connections are created on the line board, TCM section latency measurement is supported for higher-order ODU4 channels. When lower-order ODUk cross-connections are created on the line board, PM/TCM section latency measurement is supported for higher-order ODU4 channels, and TCM section latency measurement is supported for lower-order ODUk channels. |
| Physical clock | Supported (ODU0/ODU1/ODU2/ODU2e/ODU3/ODUflex) |
| SDH functions and features of the board | Description |
| Basic function | A maximum of 80 Gbit/s SDH services are supported. While matching TNU1CTU and TNS1CTU does not support SDH services. |
| 8 x STM-64<->8 x ODU2<->1 x ODU4<->1 x OTU4 | |
| 32 x STM-16<->32 x ODU1<->1 x ODU4<->1 x OTU4 | |
| Overhead processing | 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. | |
| Supports ECC communication. | |
| Supports transparent transmission of DCC channels. | |
| Service processing | Supports the VC-12/VC-3, VC-4 services, VC-4-4c concatenation services, VC-4-16c concatenation services, and VC-4-64c concatenation services. |
