Sample Overview IB – User Perspective

• The user of this system sees an ordinary telephone with a few additional switches and indicator lights. The attached keypad produces the standard telephone tones. When the user picks up the receiver, she is prompted by a light to enter her two digit identification code to gain access to the phone system before being prompted to dial a phone number. The user may, if she wishes, turn on the “set” switch to set a short code. She is then prompted to enter a one digit short code. After entering this digit, the user enters a normal phone number. When she is done, she turns off the “Set” switch. The user may dial normally, automatically redial the last regularly dialed number by entering a *, or may use the autodial function by entering # followed by the short code digit. The user may hang up at any time. If the user wishes to place another call without reidentifying herself, she may press the pre-redial switch.
