Create an SmppClient instance

	SmppClient client = new SmppClient();

Then provide connection details by populating the SmppClient.Properties property

    SmppConnectionProperties properties = client.Properties;
    properties.SystemID = "mysystemid";
    properties.Password = "mypassword";
    properties.Port = 2034; //IP port to use
    properties.Host = "196.23.3.12"; //SMSC host name or IP Address
    properties.SystemType = "mysystemtype";
    properties.DefaultServiceType = "mydefaultservicetype";

    //Resume a lost connection after 30 seconds
    client.AutoReconnectDelay = 3000;

    //Send Enquire Link PDU every 15 seconds
    client.KeepAliveInterval = 15000;

    //Start smpp client
    client.Start();

Additionally, you can handle the SmppClient.ConnectionStateChanged event to receive notifications when connection status changes

	client.ConnectionStateChanged += client_ConnectionStateChanged;

    private void client_ConnectionStateChanged(object sender, ConnectionStateChangedEventArgs e)
    {
         switch (e.CurrentState)
         {
              case SmppConnectionState.Closed:
                 //Connection to the remote server is lost
                 //Do something here

                  e.ReconnectInteval = 60000; //Try to reconnect after 1 min
                  break;
              case SmppConnectionState.Connected:
                 //A successful connection has been established
                 break;
              case SmppConnectionState.Connecting:
                  //A connection attemp is still on progress
                  break;
         }
    }
