Abstract
A ring detection device which signals a modem in a personal communication device. A detector is connected to the cellular radio telephone for detecting an incoming telephone call. An oscillator circuit generates a ringing signal for enabling a modem in response to either the cellular telephone incoming call or a ring signal received over a directly-connected PSTN network. The modem for the personal communication device responds for providing communication over either the cellular network or directly-connected PSTN network.
