Abstract:
1. An apparatus for notifying of a circuit switched event over a packetized data network, the apparatus comprising: a first tunneling link access control processor, configured to receive notification of the circuit switched event and to encapsulate or decapsulate data for a subset of sub-layers corresponding to a link access control layer of a circuit switched network modem, wherein the subset of sub-layers consists only of an addressing sub-layer and an authentication sub-layer; an internetwork interface, operatively coupled to a packetized data modem via the packetized data network, configured to notify said packetized data modem of the circuit switched event, and to transmit encapsulated or decapsulated data for the subset of sub-layers corresponding to the link access control layer, wherein the packetized data modem comprises: wherein the data for the subset of sub-layers corresponding to the link access control layer is generated by a circuit switch network according to the circuit switched event.
