摘要： A method of sending local dial tone to the subscriber from the fixed subscriber unit (FSU) is described. The method can include receiving and memorizing DTMF dialing from a connected telephone. Outpulse this DTMF dial signal information from the FSU to the network. After establishing the wireless communication between the FSU and a wireless base station, providing a cut-through of the audio path between the network and the subscriber.

摘要： Communications system comprising a set of interface devices adapted to be coupled to a public switch telephone network (PSTN) and radio transceivers. The interface devices are configured to serve in various geographic regions. The radio transceivers are coupled to the interface devices in the set of interface devices. The radio transceivers are for communication with mobile subscribers. The mobile subscribers each have a home region. The circuitry coupled to the set of interfaces routes a call through a path including an interface device that serves the mobile subscriber's home region, for a call involving the PSTN and a mobile subscriber located outside the mobile subscriber's home region.
