Configures the time division multiplexing (TDM) hierarchy to be used by the physical layer carrier system of the switch. This can be either the North American hierarchy (e.g., T1, T3, OC-3, etc.) or the European hierarchy (E1, E3, STM-1, etc.). The configuration of the TDM hierarchy is a global configuration affecting all TDM ports present in the switch. When the TDM hierarchy is changed, the command warns the user with the following messages if any CES is already configured:
Message: A save and reboot are required before the changes take effect. Upon reboot, TDM port parameters will be reset to defaults. Error: Cannot change TDM hierarchy with CES pseudo-wire(s) configured. All CES pseudo-wire(s) must be deleted before changing TDM hierarchy. Error: Cannot change TDM hierarchy with TDM service(s) configured. All TDM service(s) must be deleted before changing TDM hierarchy.

t1 |
T1, North American digital carrier hierarchy. |

e1 |
E1, European digital carrier hierarchy (default). |
The default hierarchy is E1.
Before reboot:
E4G-200#delete ces all E4G-200#delete tdm service circuit all E4G-200#configure tdm hierarchy t1 A Save and Reboot are required to make the changes effect at the next reboot of this switch. Upon reboot, TDM port parameters will be reset to defaults E4G-200#save configuration E4G-200#reboot
This command was first available in ExtremeXOS 15.1.
This command is available on the cell site routers (E4G-200 and E4G-400).
