Abstract: A cellular modem couples a data terminal equipment (DTE) to a portable mobile telephone that includes a cellular transceiver. The cellular modem monitors the activity of a circuit-switched analog cellular data connection between the DTE and a far-end data endpoint, e.g., a computer, through a cellular modem pool in the network. If the circuit-switched analog cellular data connection is idle for a predetermined amount of time, the cellular modem initiates a power-down sequence. For example, the cellular modem uses a protocol, e.g., a predefined tone, to indicate to the cellular modem pool that a power-down is occurring and that the circuit-switched analog data connection is to be put on hold.

Abstract: A Mobile Switching Center (MSC) includes a cellular modem pool that comprises a number of pairs of modems in which the data terminal equipment (DTE) ports of each modem pair are cross-connected in a "back-to-back" fashion. This allows the two modems of each pair to interchange data via their DTE ports and thereby isolate that portion of the cellular fax call over the cellular communications channel from that portion of the cellular fax call through the public-switched telephone network (PSTN). Fax information is transmitted over both the PSTN-portion of the cellular fax call and the cellular portion of the cellular fax call using standard fax modulation techniques. The cellular-side modem of each modem pair is adapted to recover fax handshaking and data signaling from the received--fax modulated--signal and translate the recovered fax information into "AT-type commands" for application to the corresponding PSTN-side modem of the modem pair.

Abstract: A cellular modem pool provides a "transparent call progress" feature where each modem pair of the cellular modem pool is coupled to a cross-connect switch, which communicates call progress information between the cellular-side and the PSTN-side during data call setup. The modem pair of the cellular modem pool monitors the call progress information for a data signal provided by a DCE of the calling party, e.g., a predefined fax calling tone. Once the fax calling tone is detected, the modem pair prohibits the opening of the connection provided by the cross-connect switch. This enables the transparent call progress feature for the duration of the fax call thereby routing the fax call around the modem pair.

Abstract: A PCMCIA wireless credit card modem is fabricated using two credit card sized sections interconnected by a hinge. The first section contains modem circuitry, and the second section contains an antenna and radio circuitry. The two sections form a 90 degree angle in the open position. The section with the modem circuitry fits into a type I or II PCMCIA slot in a portable computer, and the section with the antenna remains on the outside of the computer. The folding electronic card assembly can interface to several different PCMCIA card slots. In one embodiment, the first section fits within a Type I or Type II PCMCIA slot, and when in the closed position, the assembly fits within a Type III or Type IV PCMCIA slot.
