Abstract
A system automates interface intervals with remote telephone terminals as to provide information or advice in response to select tone signals formed at a telephone terminal, and at the conclusion of an interval provides a disconnect or termination signal prompting a caller to "hang up". Disconnect signals simulate known sounds, specifically as the "click" attendant a remote "hang up" and the traditional dial tone. The disconnect signals are transmitted to a caller after an interface interval to prompt the caller to "hang up" and release the telephone line connection.
