ABSTRACT:
There is provided a cordless telephone which can be connected to any one of digital exchanges of different protocols. A main unit of the cordless telephone is provided with a memory for storing a table for collating control data (first control data) defined by the protocol of a digital exchange to be connected and control data (second control data) inherent to the cordless telephone. The main unit also includes a protocol converting circuit 4 for conversion between the first control data and the second control data. If the cordless telephone is to be connected to another digital exchange structured in a different protocol, a protocol circuit 4 corresponding to the protocol of the digital exchange is used. Transfer of conversation between the cordless telephone and a fixed telephone can also be realized by providing a data distributing and combining circuit.
