1. A multi-carrier communications system including a plurality of communications nodes coupled to one another over a communications medium, wherein the medium includes a predetermined number of data carriers and each of the nodes includes a communications event management module, wherein the management module, for a communication event requiring use of a minimum number of carriers to satisfy a bandwidth requirement corresponding to the event, determines whether:

  • (i) currently available carriers from the predetermined number of carriers for the medium can satisfy the communications event bandwidth requirement, (ii) the minimum number of carriers does not exceed the currently available carriers, (iii) the number of currently available carriers does not exceed the predetermined number of carriers of the medium less the number of carriers of the medium not suitable for communications, and (iv) the sum of the currently available carriers and the predetermined number of event carriers does not exceed the predetermined number of carriers of the medium less the carriers of the medium not suitable for communications, and wherein, if each of the conditions (i), (ii), (iii) and (iv) is satisfied, the management module defines at least two communications channels for the system while the communications event is occurring, wherein the first channel includes a plurality of first carriers for completing the communications event as a synchronous communication and the second channel includes at least a second carrier for completing an asynchronous communication.
