1. A system for indicating to a subscriber of a network that an event has occurred giving reason to initiate a connection to the network, the system comprising:

  • a subscriber unit having a modem and a counter; and

    an indication sub-system interconnected between said subscriber unit and said host facility, said indication sub-system having a sub-system modem, said sub-system modem being interconnected via a telephone communication link with said subscriber unit modem and adapted to receive query signals from said subscriber unit and to send indication signals to said subscriber unit associated with said subscriber;

    wherein said subscriber unit is adapted to send said query signals to said indication sub-system modem from said subscriber modem, said sub-system modem is adapted to identify said subscriber unit from said query signal and to determine whether said event has occurred, and said counter is adapted to terminate said query signal without establishing a connection with said sub-system and adapted to wait a predetermined period of time for said subscriber modem to receive a responsive indication signal from said indication sub-system in response to said query signal; and

    wherein said sub-system modem is further adapted, if said event is determined to have occurred, to send an indication signal to said subscriber modem within said predetermined period of time.
