    [RouterB-voice-dial-entity2001] send-number all
    [RouterB-voice-dial-entity2001] line 2/3/1
    [RouterB-voice-dial-entity2001] return
    

    # Enter the view of E&M interface 5/0. The E&M interface must have the same configuration as the connected PBX.

    <RouterB> system-view
    [RouterB] subscriber-line 2/3/1
    

    # Configure the wink start mode.

    [RouterB-subscriber-line2/3/1] signal wink
