CPOS Interface Configuration
You can configure CPOS interfaces on a router to converge E1/T1 lines of a SONET/SDH network.
- Overview of CPOS Interfaces
A CPOS interface is a channelized POS interface that allows a device to effectively converge low-speed access lines. - Understanding CPOS Interfaces
- Licensing Requirements and Limitations for CPOS Interfaces
This section describes licensing requirements and limitations for CPOS interfaces. - Application Scenarios for CPOS Interfaces
- Default Settings for CPOS Interfaces
This section describes the default settings for CPOS interfaces. - Configuring CPOS Interfaces to Connect Devices
When the headquarters and the branch need to transmit data over a long distance through CPOS interfaces, you can configure CPOS interfaces to connect devices through optical fibers or using WDM. - Configuring CPOS Interfaces to Converge E1 Lines
Multiple branches access the SONET/SDH network through E1 lines. To lower costs and improve the convergence ability of the device for low-speed access, the regional headquarters uses CPOS interfaces to converge these E1 lines. In this way, data can be transmitted between the regional headquarters and its branches. The E1 system is widely used in Europe and China. - Configuring CPOS Interfaces to Converge T1 Lines
Multiple branches access the SONET/SDH network through T1 lines. To lower costs and improve the convergence ability of the device for low-speed access, the regional headquarters uses CPOS interfaces to converge these T1 lines. In this way, data can be transmitted between the regional headquarters and its branches. T1 system is widely used in North America and Japan. - Maintaining CPOS Interface Configuration
You can enable the loopback function to detect whether an interface runs properly and clear interface statistics to maintain CPOS interfaces. - Configuration Examples for CPOS Interfaces
This section provides CPOS interface configuration examples including the networking requirements, configuration roadmap, operation procedure, and configuration files. - Troubleshooting CPOS Interfaces
This section provides the common configuration errors.
