PDF containing scanned images of the details of my April 1995 BT plc "Work Experience" student placement arrangement within the Company's Merseyside (0151 telephony) area. On this `placement I saw various telephone exchange (switching) systems and a number of Remote Concentrator Unit (RCU) installations which were connected to such exchanges e.g. the Whaley Lane, Irby, RCU premises that's connected to the Arrowebrook telephone exchange. The Irby RCU had the numbering-plan designation 0151 648. The last page of this PDF displays a monochrome photo-copy of the BT plc Work Experience Certificate awarded to me.
