Table 1 TOX Single Board Functions and Features| Functions and Features | Description | ||
|---|---|---|---|
| Basic Functions |
TOX supports the conversion of signals:
|
||
| Customer Side Service Types |
STM-64/OC-192: SDH/SONET service at 9.95 Gbit/s 10GE LAN: Ethernet service at 10.31 Gbit/s 10GE WAN: Ethernet service at 9.95 Gbit/s OTU2: OTN service at 10.71 Gbit/s OTU2e: OTN service at 11.1Gbit/s FC800: SAN service at 8.5 Gbit/s FC1200: SAN service at 10.51Gbit/s Description:
Only the TN56TOX supports FC800 and FC1200 services. |
||
| Crossover Capability |
The TOX supports 8 ODU2/ODU2e/ODUflex signals to cross-schedule services with the cross board via the backplane bus. Description:
Only the TN56TOX supports ODUflex scheduling. |
||
| OTN Function. |
|
||
| ESC Function |
Supported when the client side accesses OTU2/OTU2e services. |
||
| Error Correction Coding | FEC coding is supported on the client side only when accessing OTU2/OTU2e, in accordance with ITU-T G.709 recommendations. | ||
| Performance Monitoring and Alarm Monitoring |
|
||
| ALS Function |
Supported on the client side when accessing non-OTN services. |
||
| PRBS Function |
The PRBS function is supported on the client side. Description:
The PRBS function is supported on the client side only when accessing STM-64/OC-192, OTU2, and OTU2e services. |
||
| LPT Function. |
The LPT function is supported only when the service type of the customer side is 10GE LAN. |
||
| Test frame function | Test frame function is supported when the customer side accesses 10GE LAN service and the "Port Service Mapping Path" is "MAC Transparent Mapping (10.7G)". | ||
| Delay Measurement | The single board supports delay measurement. It can measure the bidirectional delay of ODUk layer between two tributary boards, and the delay data is displayed on the network management. Description: When the client side accesses OTU2/OTU2e services, delay measurement is not supported. |
||
| IEEE 1588v2 |
TC mode, TC+OC mode, BC mode and OC mode are supported when the client side accesses 10GE LAN service and the "Port Service Mapping Path" is "MAC Transparent Mapping (10.7G)". Description:
|
||
| Physical Layer Clocking |
|
||
| Layer ASON | Support | ||
|
Ethernet service encapsulation |
Bit transparent mapping (11.1G), MAC transparent mapping (10.7G) | ||
| Port MTU |
1518～9600 bytes, i.e. supports Jumbo frames up to 9600 bytes. Description:
When the "Port Service Mapping Path" is "Bit Transparent Mapping (11.1G)", port MTU setting is not supported. |
||
| Protection Mode |
Description:
When the scheduling granule is ODUflex, branch SNCP protection is not supported. Description:
Branch SNCP protection is supported only when the customer side accesses OTN services, SDH/SONET services, and 10GE WAN services. |
||
| Loopback | Wavelength Division Side | - | |
| Customer Side | Internal Loopback | Supported | |
| Outer Loopback | Supported | ||
|
Supported Protocols or Standards |
Protocols or standards for pass-through (no performance monitoring) |
