Configuring the Signaling Mode of an E&M Interface

Configuring the Signaling Mode of an E&M Interface


When a router connects to a device through an E&M interface, the signaling modes on the router and the device must be same so that data can be transmitted between them. You can configure the signaling mode of the E&M interface on the router based on that of the connected interface of the device.


  1. Run system-view

    The system view is displayed.

  2. Run interface serial interface-number

    The E&M interface view is displayed.

  3. Run em signal-mode { bell-1 | bell-2 | bell-3 | bell-4 | bell-5 }

    The signaling mode is configured for the E&M interface.

    By default, the signaling mode of an E&M interface is Bell-5.


    Currently, the device does not support the Bell-1, Bell-2, Bell-3, and Bell-4 signaling mode.
