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.
Pre-configuration Tasks
Before configuring CPOS interfaces to converge T1 lines, complete the following tasks:
Registering the 1CPOS-155M-W interface card
Ensuring that the configuration of multiplexing path TUGs on the SDH transmission device corresponds to the T1 channel number of the CPOS interface
