Abstract
A message waiting notification system comprising a telephone provider's off premise central switching office connected to a Dual Signal Triggered Message Waiting Indicator (DSTMWI) circuit via a telephone line is disclosed. The central switching office transmits predetermined asynchronous Frequency Shift Keying (FSK) signals and/or audible tones indicating different types of electronically stored communication messages awaiting retrieval, such as voice mail, E-mail, fax mail and video mail. Responsive to receiving the FSK signals and/or audible tones from the central switching office via the telephone line, the DSTMWI circuit provides visual notification of any combination of different types of the electronically stored communication messages.
