§ Mr. Ben Chapman
To ask the Secretary of State for Health how many individual lines are operated as part of the touch tone steering system installed in his Department's public inquiry office. 
§ Ms Stuart
Five individual agent's lines are operated as part of the Automated Call Distribution (ACD) system, plus one supervisor line.
The ACD system has the ability to queue calls in excess of the six lines available, the maximum number of which is dependent upon the loading on the switch at the time the call is placed.
Eight lines are operated to provide messaging services at pre-determined times (such as to provide the out of hours messages).
