/**

 * Constants used in package javax.megaco.association. This forms the class for

 * the association state of the Association package. The association here refers

 * to the association w.r.t the peer i.e., MG-MGC association. The state here

 * refers to the state of the control association between MG-MGC. These states

 * would assist the application in making decisions regarding when and what

 * commands to initiate towards the peer. For eg. untill the association is in

 * state M_REG_COMPL, the application should not send any commands to the stack.

 * Similarly, if the association is in M_GRACEFUL_SHUTDOWN_IN_PRGS state and if

 * the application is MGC, then it should refrain from establishing new calls,

 * therefore it should not send new ADD commands.
