Table 1 TTX Single Board Functions and Features
| Functions and Features | Description | ||
|---|---|---|---|
| Basic Functions | Realize the interconversion of the following signals:
Description:
| ||
| Customer Side Service Types | STM-64/OC-192: SDH/SONET service at 9.95Gbit/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 TN55TTX supports access to OTU2/OTU2e/FC800/FC1200 services. | ||
| Cross-capability | Supports 10 ODU2/ODU2e/ODUflex signals to realize cross-scheduling of services through the backplane bus with the crossover board. Description: Only the TN55TTX supports ODUflex scheduling. | ||
| OTN Features. |
| ||
| ESC function | Supported when accessing OTU2/OTU2e services. Description: Supports ESC function for up to 8 channels. | ||
| 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/OTU2e services. The TN54TTX can only configure PRBS for one port at the same time. the TN55TTX has no such restriction. | ||
| LPT Function | The LPT function is supported only when the client-side service type is 10GE LAN. | ||
| Error Correction Coding |
| ||
| Performance Monitoring and Alarm Monitoring |
| ||
| ALS Function | Supported on the client side when accessing non-OTN services. | ||
| Test frame function |
| ||
| 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. Only one port can be configured for delay measurement at the same time. | ||
| IEEE 1588v2 |
| ||
| Physical layer clock | TN54TTX: When the client 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. TN55TTX: When the customer side accesses 10GE LAN service and the port service mapping path is Bit transparent mapping (11.1G), synchronous Ethernet passthrough is supported and synchronous Ethernet processing is not supported; when the port service mapping path is MAC transparent mapping (10.7G), synchronous Ethernet processing is supported and synchronous Ethernet passthrough is not supported. | ||
| Layer ASON | Support | ||
| Protection Mode |
Description: Supports branch SNCP protection only when the customer side accesses OTN service, SDH/SONET service, and 10GE WAN service. | ||
| Ethernet service encapsulation method |
| ||
| Port MTU | 1518 to 9600 bytes, i.e. supports Jumbo frames up to 9600 bytes. Description:
| ||
| Loopback | Client side | Internal Loopback | Support |
| External Loopback | Supported | ||
| Channel Loopback | Not Supported | ||
