System and method for providing wireless connections for single-premises digital telephones
First Claim
1. A system for supporting digital telecommunications comprising:
- a single-premises digital telephone of a type compatible with wireline digital telecommunications with other-premises digital telephones, said single-premises digital telephone being at a local site;
converter means connected to said single-premises digital telephone at said local site for converting between a digital wireline signaling format compatible with bidirectional wireline telecommunications and an analog wireless signaling format compatible with bidirectional wireless telecommunications, said converter means being connected to said single-premises digital telephone for signal transfers using said digital wireline signaling format; and
transceiver means, connected to said converter means at said local site, for signal exchanges with said converter means using said analog wireless signaling format and for wirelessly transmitting and receiving telecommunications signals using said analog wireless signaling format said single-premises digital telephone being isolated from digital wireline telecommunications outside of said local site such that communication with said single-premises digital telephone from remote sites is limited to wireless communications via said transceiver means.

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.
