ABSTRACT:
A system and method for communicating between local subscriber units and a local base station repeater cell in a two-way communication interactive video network. In one embodiment, a modem is used to enable communications between a subscriber unit and a local base station repeater cell when the subscriber units are unable to receive rf transmissions from the local base station repeater cell. The local base station repeater cell is connected via a telephone line to the modem. Data communications are sent from the local base station repeater cell to the modem. The modem is also connected via and rf link to the subscriber unit. The modem then transmits the data communications received from the local base station repeater cell to the subscriber unit. Responses from the subscriber unit are then transmitted over the rf link from the subscriber unit to the modem. The modem then transmits the responses over the telephone line to the local base station repeater cell.
