Demo Boards For KPN we delivered 2 batches of each 9 demo boards. These demo boards are used for training and presentation purposes. Each demo board is equipped with a different telephone setup (ADSL, VDSL, IP-television, Analogous telephone, ISDN, etc), which reflects a real live situation in the field. Skilled back end KPN service engineers are using these demo boards to give training to front end call center employees, to give them a better understanding of the different and various telephone setups in the field. With the use of the demo boards they can understand real live sitations better which they can use to help the customer faster and better.
