//Description:
//      There is only one Cross Connector Mux (CCM) in the whole system. 
//      The CCM holds references to callID muxes whose default route is 
//      connected to call instance factories. In the connection establishment 
//      state the CCM is used to route messengers to a correct link. 
//      Combination of the CCM and the callID mux is also used to route 
//      INAP-messengers to a correct link and call instance.
