Abstract: This invention provides a method of conferring osmoprotection to plants. Plant plastid genomes, particularly the chloroplast genome, is transformed to express an osmoprotectant. The transgenic plants and their progeny display drought resistance. More importantly, such transgenic plants display no negative pleiotropic effects such as sterility or stunted growth.

Abstract: A digital cordless telephone system comprises a multiplicity of subscriber cordless handsets (HS's) with a subscriber number of a private automatic branch exchange (PABX) being assigned to one or more of the HS's, a plurality of base stations (BS's), each of the BS's being coupled with one or more of the HS's by radio channels for controlling a radio link between each of the BS's and each of the HS's, and a system connecting unit coupled with the BS's and the PABX for allowing only authenticated HS's to initiate outgoing calls and for keeping track of each of the HS's to set up calls for the HS's whenever the HS's are within the service area of one of the BS's.

Abstract: A digital cordless telephone (CT-2) system, having a multiple number of subscriber cordless handsets (HS's) and a subscriber manager which performs authentication for the HS's, comprises a plurality of base stations (BS's), each of the BS's being coupled with one or more HS's by radio channels for controlling radio link; and a system connector coupled with each of the BS's, coupled with a public switched telephone network (PSTN) for switching and concentrating channels between each of the BS's and the PSTN, and coupled with a public switched data network (PSDN) for communicating with the subscriber manager.
