Configuring CE1 Channels Down to DS Interfaces

 

You can configure a DS interface on a channelized E1 interface (CE1) and then apply CESoPSN encapsulation for the pseudowire to function. An NxDS0 interface can be configured from a channelized CE1 interface, where N represents the time slots on the CE1 interface. The value of N is 1 through 31 when a DS0 interface is configured from a CE1 interface.

To configure CE1 channels down to a DS interface, include the partition statement at the [edit interfaces ce1-fpc/pic/port] hierarchy level, as shown in the following example:

After you partition the DS interface, configure the CESoPSN options on it. See Setting the CESoPSN Options.

To configure CE1 channels down to a DS interface:

  1. Create the CE1 interface.

    For example:

  2. Configure the partition, the time slot, and the interface type.

    For example:

    Note

    You can assign multiple time slots on a CE1 interface; in the configuration, separate the time slots by comma without spaces. For example:

  3. Configure the CESoPSN encapsulation for the DS interface.

    For example:

  4. Configure the logical interface for the DS interface.

    For example:

When you are finished configuring CE1 channels down to a DS interface, enter the commit command from configuration mode.

From configuration mode, confirm your configuration by entering the show command. For example:
