发明名称 Apparatus for use in a telephone exchange including an operator cordboard position

The apparatus comprises a keyboard and display unit and an independently operable processing and storage unit provided individually for each operator position, the operator position and keyboard and display unit being connected to the processing and storage unit. Each operator position functions with its associated units independently of the other operator positions and any central processing unit.

The concentrator is connected to teletypewriters and also to a storage unit for storage of call records in the event of failure of the automatic message accounting equipment.
