Optix OSN8800 TN55TQX 4-Channel 10G Tributary Service Processing Board Functions and Features
The TQX single board supports functions and features such as electrical layer crossing.
The TQX single board functions and features, as shown in Table 1.
Table 1 TQX Single Board Functions and Features
| Functions and Features | Description | ||
|---|---|---|---|
| Basic Functions | Realizes the interconversion of the following 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 TN52TQX/TN53TQX/TN55TQX/TN57TQX support OTU2 and OTU2e services. Only TN53TQX/TN55TQX/TN57TQX support FC800, FC1200 services. 10GE WAN is processed the same as STM-64. For TN11TQX/TN52TQX, it is enough to configure as STM-64 on the network management when transmitting 10GE WAN service. | ||
| Crossover Capability | The TQX supports 4 ODU2/ODU2e/ODUflex signals to realize cross-scheduling of services with the cross board via the backplane bus. Description: Only the TN55TQX/TN57TQX supports ODUflex scheduling. | ||
| OTN Functions |
| ||
| ESC Function | Supported when TN52TQX/TN53TQX/TN55TQX/TN57TQX 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 test function | 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 on 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 | TN53TQX/TN55TQX(standard mode)/TN57TQX boards support delay measurement. The bidirectional delay of ODUk layer between two tributary boards can be measured, and the delay data is displayed on the network management. Description: When the customer side accesses OTU2/OTU2e services, the delay measurement is not supported. | ||
| IEEE 1588v2 | TN55TQX supports TC mode, TC+OC mode, BC mode and OC mode when the client side accesses 10GE LAN service and the "Port Service Mapping Path" is "MAC Transparent Mapping (10.7G)". | ||
| Physical Layer Clock | TN55TQX.
TN52TQX/TN53TQX: When the customer side accesses 10GE LAN service and the port service mapping path is "Bit Transparent Mapping (11.1G)", Synchronous Ethernet pass-through is supported and Synchronous Ethernet processing is not supported. | ||
| Layer ASON | Supported by TN52TQX/TN53TQX/TN55TQX/TN57TQX. | ||
| 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. | ||
Ethernet service encapsulation method | 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. | ||

| Customer Side | Internal Loopback | Supported | |
| Outer Loopback | Supported | ||
Supported Protocols or Standards | Protocols or standards for pass-through (no performance monitoring) | IEEE 802.3ae ITU-T G.707 ITU-T G.782 ITU-T G.783 GR-253-CORE Synchronous Optical Network (SONET) Transport Systems: Common Generic | |
Protocols or standards handled (with 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 | ||
