The central unit is arranged for receiving a plurality of second control signals from a plurality of listening units, and indicating which audio channel on a listening unit of the plurality of listening units is selected, for deriving, based on the plurality of second control signals, a total of listeners per listening channel and for sending to and displaying on the plurality of interpreter desks, information on the total of listeners per listening channel. ## Claims ### Claim at position 1 1-7. (canceled) ### Claim 8 A central unit for a digital conferencing system comprising a processing unit arranged for receiving a plurality of first control signals from a plurality of interpreter desks, said plurality of first control signals indicating which interpreter channel is selected on an interpreter desk, and for identifying, based on said plurality of first control signals, which interpreter is interpreting in which interpreter channel and arranged for, based on said identification, returning to and displaying on said plurality of interpreter desks a plurality of feedback signals, said feedback signals allowing the interpreters to know whether and by whom the interpreter channel they are using is taken over, said central unit further arranged for receiving a plurality of second control signals from a plurality of listening units, said plurality of second control signals indicating which audio channel on a listening unit of said plurality of listening units is selected, for deriving, based on said plurality of second control signals, a total number of listeners per listening channel and for sending to and displaying on said plurality of interpreter desks, information on said total number of listeners per listening channel. ### Claim 9 (depends on 8) A conferencing system comprising a central unit as in claim 8. ### Claim 10 (depends on 9) The conferencing system as in claim 9, comprising a plurality of interpreter desks. ### Claim 11 (depends on 9) The conferencing system as in claim 9, comprising a plurality of listening units. ### Claim 12 (depends on 10) The conferencing system as in claim 10, comprising a plurality of listening units. ### Claim 13 (depends on 10) The conferencing system as in claim 10, in which an interpreter desk of said plurality comprises a screen on which is indicated whether a recording is being made of the interpreter channel used, based on said second control signals. ### Claim 14 (depends on 11) The conferencing system as in claim 11, in which an interpreter desk of said plurality comprises a screen on which is indicated whether a recording is being made of the interpreter channel used, based on said second control signals. ### Claim 15 (depends on 12) The conferencing system as in claim 12, in which an interpreter desk of said plurality comprises a screen on which is indicated whether a recording is being made of the interpreter channel used, based on said second control signals. ### Claim 16 (depends on 10) The conferencing system as in claim 10, wherein at least one interpreter desk of said plurality comprises a processing unit equipped to, based on said first control signals, indicate by whom a sent out translation is to be taken over in another interpreter desk, or with which other translation said sent out translation is to be mixed in another interpreter desk. ### Claim 17 A method for providing information on the use of an interpreter channel to an interpreter in a digital conferencing system, comprising the steps of: receiving in a central unit of said digital conferencing system, a plurality of first control signals from a plurality of interpreter desks, said plurality of first control signals indicating which interpreter channel in an interpreter desk of said digital conferencing system has been selected; identifying, based on said first control signals, which interpreter is interpreting in which interpreter channel; sending back to said plurality of interpreter desks a plurality of feedback signals based on said identification and displaying said plurality of feedback signals on said plurality of interpreter desks; the method further comprising: receiving in said central unit, a plurality of second control signals from a plurality of listening units, said plurality of second control signals indicating which listening channel on a listening unit of said plurality of listening units is selected; deriving, based on said second control signals, a total number of listeners per listening channel; sending back information on said total number of listeners per listening channel to said plurality of interpreter desks.
