    摘要: A system and method for delivering electronic messages over a wireless cellular communications network when the sender of a message is out of the coverage area of any cell within the network. With this method the message is broadcast repeatedly until a mobile wireless courier receives the message when it is range and stores the message. When the courier is within range of a base station of the cellular communication network, it then transmits the stored message to the base station for transmission to a requested destination.

    摘要: The packet network phone unit is an interface between a telephone instrument and a packet network for enabling voice data to be communicated over the packet network. The unit also functions as a gateway between a packet network and a public switched telephone network, thereby interconnecting the networks and providing a public switched telephone network gateway to a packet network. When power is not supplied to the unit, a fallback switch automatically links the telephone instrument directly to the public switched network, bypassing the circuitry in the unit. The unit includes links to a plurality of external serial communications lines as well as an interface for connecting to a personal computer. The unit also includes an LCD driver and a display for displaying information such as a caller identification. The packet network phone unit also may function an answering machine/messaging system.
