public class ConnectionHandlerImpl

extends java.lang.Object

implements ConnectionHandler

This is the implementation of the ConnectionHandler interface which helps the user to take some action before and after connecting to the TL1Agent. This interface can also enable the user setup the device in the TL1 mode. For example,some devices expect a particular sequence of ACSII characters (say,"\n\r;") before it can start operating in the TL1 mode. On the other hand, some devices send banners (ASCII text strings) before on establishing connection.This can cause the API to throw parse exceptions since these text strings are not in TL1 format. This methods in this interface can help bypass the banner so that the TL1 communcation can proceed.
