Improvements in telephone technician's terminals.

摘要

An improved craft technician's field terminal of the portable, hand-held type for use in communicating in diverse modes with a central technician access network. The terminal is connected with the telephone line in conventional manner in communication with the telephone access network. Job data can then be transmitted from the central network and downloaded to the terminal for instantaneous display. Re-transmission can be requested if need. The terminal is capable of uploading data from the terminal display in either DTMF and/or ASCII to the central network. The craft technician's terminal contains a much greater storage capacity than any similar devices heretofore and it is capable of holding job order and response data for what amounts to greater than a full days technician work. In addition, data displayed at the terminal may readily be transmitted for printer access while still being retained in the terminal storage.
