Understanding TDM Ports Numbering

ExtremeXOS supports 16 TDM ports on E4G-200 and E4G-400 cell site routers.

The TDM ports are numbered from 1 to 16 in the face-plate of the switch. However, when the TDM ports are configured using the ExtremeXOS CLI, the TDM ports are numbered sequentially after the Ethernet ports. The following table shows the port number mapping in E4G-200 and E4G-400 cell site routers.

TDM Port Number Mapping for E4G-200 and E4G-400

Cell Site Router Module Panel TDM Port Numbers TDM Port Numbers in ExtremeXOS CLI
Note that the panel TDM port numbers are different from the TDM port numbers used for the configuration.
E4G-400 E4G-B16T1E1 1–16 35-50
E4G-200 E4G-F16T1E1 1–16 13–28

In E4G-200, the port number 13 in the ExtremeXOS CLI refers to the TDM port 1 in the face-plate. Similarly, port 14 in the ExtremeXOS CLI refers to TDM port 2 in the face-plate and so on.

In E4G-400, the port number 35 in the ExtremeXOS CLI refers to the TDM port 1 in the face-plate. Similarly, port 36 in the ExtremeXOS CLI refers to TDM port 2 in the face-plate, and so on.
