| titleOfInvention | Radio pbx for personal communications system |
| abstract | A Radio PBX for use in a Digital Mobile Telephone system is provided. The Radio PBX includes a plurality of transceivers to transmit and receive RF signals to and from subscriber units and/or an external base station in which at least a set of transmitter and receiver is repeating those RF signals converting their frequencies and/or protocol, and said radio PBX is connected to one common indoor antenna and/or one common outdoor antenna. These transceivers have a capability to detect said RF signals into base band signals and modulated into new RF signals by interconnecting said base band signals between said transmitter and receiver. Moreover, each transceiver is tailored and/or automatically assigned for one of the Control trunk, Repeater trunk, Local Line trunk, Service trunk, and/or Incoming and Outgoing Line trunk within a radio PBX. The control trunk is provided to synchronize with an external base station, to control the control channel to and from an external base station and/or subscriber unit within a serving area. The repeater trunk is provided to connect the communications between said base station and said subscriber units, and/or between the central trunks means and said subscriber units. The local line trunk is provided to connect the communications between said subscriber units. The service trunk provides 3-way call bridge, voice mail, etc. The incoming and outgoing line trunk is provided to connect the communications between telephone lines and said subscriber units, and/or between telephone lines and repeater trunks. |
