Abstract
Abstract A multiple attendant position telephone switching system is arranged with switching circuitry responsive to the removal of an attendant''s headset at any one position to permit an attendant at another position to answer calls that would otherwise be directed to the position from which the headset has been removed. The switching circuitry is arranged to recognize and to respond to the occupied or unoccupied status of the positions so as to interconnect unoccupied positions with adjacent occupied positions prior to interconnecting those positions with positions more remotely located. Occupied consoles may be selectively interconnected so that an idle attendant may assist a busy attendant on a one call basis under control of the assisting attendant.

Claim 3
Dependent Claim
38 words
In a telephone system the combination set forth in claim 1 wherein said interconnecting means includes means for interconnecting said one position with a preselected one of said adjacent positions when each of said adjacent positions is occupied.
Claim 4
Dependent Claim
61 words
In a telephone answering bureau: a plurality of numerically designated attendant positions; attendants'' headsets for said positions; means for disconnecting said headsets from said positions; and means responsive to the disconnection of an attendant''s headset from one of said positions for interconnecting said one position with the next designated position in one direction from said one position containing an attendant''s headset.
Claim 5
Dependent Claim
61 words
In a telephone answering bureau: a plurality of numerically designated attendant positions; attendants'' headsets for said positions; means for disconnecting said headsets from said positions; and means responsive to the disconnection of an attendant''s headset from one of said positions for interconnecting said one position with the next designated position in one direction from said one position containing an attendant''s headset.
Claim 6
Dependent Claim
84 words
A telephone answering bureau in accordance with claim 3 wherein said interconnecting means includes means for determining whethEr the positions means includes means for determining whether the positions next numerically designated in said one and the opposite direction from said one position are occupied and means jointly responsive to a determination that said next position in said opposite direction is occupied and said next position in said one direction is unoccupied for interconnecting said one position with said next position in said opposite direction.
Claim 7
Dependent Claim
100 words
In a telephone system: a plurality of numerically designated attendant positions; a headset for each said position; means for detecting the occupied status of said positions; means responsive to the disconnection of a said headset from one of said positions for grouping said one position with the next lower designated occupied position; means controlled by said detecting means for inhibiting said grouping whenever a higher designated adjacent position is occupied and a lower designated adjacent position is unoccupied; and means responsive to the enabling of said inhibiting means for grouping said one position with said occupied higher designated adjacent position.
Claim 8
Dependent Claim
