An apparatus provides notification of a circuit switched event over a packetized data network. The apparatus includes a packetized data modem that is configured to receive lower level packetized data over the packetized data network that comprises the notification. The packetized data modem has a first service-oriented tunneling link access control processor that is configured to decapsulate an Improved 1x Layer 3 General Page Message (IGPM) from the lower level packetized data, where the IGPM comprises a service option corresponding to the circuit switched event. |
