<p>A fixed wireless telephone system (100) saves the tremendous cost of providing the infrastructure required for a wire line telephone system and allows rapid installation of the service. In particular, this fixed wireless telephone system (100) allows remote testing, maintenance and re-programming of a fixed wireless telephone (FWT 101) from a remote base station (103) as if it is a land line telephone apparatus connected via wires to the telephone central office. In order to facilitate this feature a special message is transmitted from a base station (103) to the FWT (101). The FWT (101) identifies the message as a silent maintenance call and disactivates the ringer circuitry. Upon reception of the message, the FWT (101) requests a call set-up (507) in the communication system (100) to a predetermined maintenance number. In a preferred embodiment, a system controller (125) in the base station (103) recognises the request to the predetermined maintenance number and provides a communication channel between the system controller (125) and the FWT (101). The base station (103) can now perform testing, maintenance and re-programming of the FWT (101). When remote re-programming, the preferred embodiment provides a verification process by providing a second communication channel from a second base station for verifying any re-programming that was performed by the first base station.</p> |
