/**
 * Binding to SMSC can be either {@link SmppBindType#TRANSMITTER} or
 * {@link SmppBindType#TRANSCEIVER}. In the first case, only the client sends
 * PDUs to the SMSC. In the second case, the server may send PDUs to the client
 * for:
 * 
 * 
 * Acks
 * {@link EnquireLink} requests to ensure that the client is still
 * alive
 * ...
 * 
 * 
 * 
 * This handler sends a response to the SMSC when a {@link EnquireLink} is
 * received. This is to send an ack that the {@link EnquireLink} has been
 * received correctly and it tells to the server that the client is still alive.
