Multiplexing E1/T1 to STM-1

Multiplexing E1/T1 to STM-1

In the process of SDH multiplexing recommended in G.709, there is more than one multiplexing path from a valid payload to STM-N.

Figure 15-4 and Figure 15-5 show the multiplexing from E1/T1 to STM-1.

Figure 15-4  Process of multiplexing E1 to STM-1

Figure 15-5  Process of multiplexing T1 to STM-1

In application, different countries and regions may adopt different multiplexing paths. To ensure mutual communication, the device provides the multiplex mode command on the CPOS interface so that you can select the AU-3 or AU-4 multiplexing path.
