Abstract
A system and method for supporting digital communications for a single-premises wireline digital telephone include converting between a first signaling format that is compatible with conventional bidirectional wireline telecommunications and a second signaling format that is compatible with bidirectional wireless telecommunications. In the preferred embodiment, the single-premises telephone is a feature phone having a visual readout or light display that is activated upon receiving party-specific call messages. A connection from the digital telephone to an interface may include protocol conversion and/or digital-to-analog conversion that utilizes the first signaling format. On the other hand, signal transfers between the interface and the transceiver utilize the second signaling format. In one embodiment, the single-premises digital telephone is remotely located from a switching network, such as a private branch exchange, so that the switching network supports the call features of the feature phone. In another embodiment, the single-premises digital phone is on the premises of the switching network, allowing alternative connectivity schemes for a call.
