| 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 | 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). |
| Ethernet port working mode | 1000M Full-Duplex |
| Loopback | WDM side | - |
| Client side | Inloop | Supported |
| Outloop | Supported |
| Protocols or standards compliance | Protocols or standards for transparent transmission (non-performance monitoring) | IEEE 802.3z |
| Protocols or standards for service processing (performance monitoring) | ITU-T G.805 ITU-T G.806 ITU-T G.709 ITU-T G.872 ITU-T G.7710 ITU-T G.798 ITU-T G.874 ITU-T M.3100 ITU-T G.874.1 ITU-T G.875 ITU-T G.808.1 ITU-T G.841 ITU-T G.8201 ITU-T G.873.1 ITU-T G.694.1 |
