Configuring the Working Mode for an E1 Interface

Configuring the Working Mode for an E1 Interface

This section describes how to configure the working mode of a channelized E1 interface. E1 interfaces can work in either clear channel mode or channelized mode.

Context

An E1 interface can form serial interfaces with different transmission rates:
  • If an E1 interface works in clear channel mode, the E1 interface forms a synchronous serial interface without timeslot division and with a transmission rate of 2.048 Mbit/s.

  • If an E1 interface works in channelized mode, timeslots 1 to 31 of the E1 interface can be randomly bundled into channel-sets to form serial interfaces, each with a transmission rate of N x 64 kbit/s.

NOTE:

The configuration of channelized mode is supported only on the Admin-VS.

Procedure

  • Create a serial interface that works in clear channel mode.

    1. Run system-view

      The system view is displayed.

    2. Run controller e1 controller-number

      The E1 interface view is displayed.

    3. Run using e1

      The E1 interface is configured to work in clear channel mode, establishing a serial interface without timeslot division and with a transmission rate of 2.048 Mbit/s.

      You can run the interface serial controller-number:0 command to enter the serial interface view.

    4. Run commit

      The configuration is committed.

  • Create a serial interface that works in channelized mode.

    1. Run system-view

      The system view is displayed.

    2. Run controller e1 controller-number

      The E1 interface view is displayed.

    3. Run using ce1

      The interface is configured to work in channelized mode.

    4. Run channel-set set-number timeslot-list slot-list

      A serial interface with a transmission rate of N x 64 kbit/s is created. N stands for the number of bundled timeslots.

      To change the working mode of an E1 interface:

      • Delete serial interfaces and their configurations and channelization configurations before you run the using e1 command to switch an E1 interface from the channelized mode to the clear channel mode.
      • Delete clear channel configurations and serial interface configurations before you run the using ce1 command to switch an E1 interface from the clear channel mode to the channelized mode.

      You can run the interface serial controller-number:set-number command to enter the serial interface view.

    5. Run commit

      The configuration is committed.
