Abstract: An automatic dialer adapted to efficiently blend the capabilities of an automatic answering machine and a central paging system wherein the automatic dialer detects messages left with the answering machine and in response thereto dials the central paging system, gains access thereto, dials the pre-programmed number of a pager, causing the central paging system to immediately page the user. The automatic dialer page assures that the proper information is conveyed to the central paging system, continuing to recycle internal calling circuitry until the call has been properly completed.

Abstract: An electronic hold circuit for a telephone. A single sensing and latching module is connected across the telephone lines, and is adapted to sense the voltage present on the telephone lines to distinguish between on-hook, off-hook and hold conditions. The hold feature is engagable by one or more hold signaling modules disposed, for example, near each telephone and extension telephone in the system. Each hold signaling module comprises a switch associated with a level establishing device, for establishing a voltage on the telephone lines at a level intermediate the relatively high on-hook voltage and the relatively low off-hook voltage. The sensing and latching module responds to this intermediate level by latching the telephone lines at a voltage sufficiently low to maintain the connection with the called or calling party.
