发明名称 Data call transfer
摘要 This data call transfer arrangement enables a calling party to originate a data call from a telephone station set and then transfer the data call to one of a number of predefined digital terminals. This is accomplished by operating the DATA button on the telephone station set corresponding to the selected digital terminal once the data call is established. This action causes the subject telephone switching system to replace the telephone station set on the call appearance with the selected digital terminal.
