Appl. No.:

6/581283

Inventors:

Peter D. Olson - Saratoga CA
Samuel R. Hawes - Palo Alto CA

Assignee:

Octel Communications, Inc. - San Jose CA

International Classification:

H04M 1100

US Classification:

179 84VF

Abstract:

Tone detection apparatus and a corresponding method is disclosed. The improved tone detector and method is for use in a preferred embodiment in a voice message answering system to provide for improved dual tone multi-frequency tone detection where an outgoing analog voice signal is connected to a telephone line. When an incoming call is detected, the tone detector looks at the incoming analog signal and if a dual tone control signal is detected, a filter is switched to filter the outgoing analog signal so that the DTMF tone signal now being detected is filtered out of the outgoing signal. If the incoming signal still detects a tone, the improved tone detector cuts off or disconnects the outgoing signal completely for approximately 20 milliseconds. If a dual tone control signal is still detected, it is determined that it is an incoming control signal and consequently access is required into the voice message system.

379283

Abstract:

A digital line card is provided for use in an electronic messaging system for enabling the receipt of voice and text or image data over a single communications port. The digital line card includes a digital signal processing integrated circuit, a microprocessor and a random access memory component for storing coding schemes employed by the digital signal processing integrated circuit. The digital line card is programmed to detect the presence of dual-tone multifrequency command signals in the incoming data stream, and to switch between voice and data processing responsive to the command signals.

International Classification:

H04M 164

US Classification:

379 88

Abstract:

Apparatus and methods are provided for non-simultaneously creating and storing in electronic format a composite voice/data message having a recorded voice message portion and a facsimile transmittal portion. The method provides for creating a voice message and sending a time-wise separated facsimile transmittal to a voice message/data storage system, and then associating the separate voice message and facsimile transmittal portions to form a composite voice/data message. The methods include a message identification scheme wherein a message identification number is assigned to the first-received message portion, and the caller is prompted to provide that message identification number in connection with the later-received message portion. Apparatus to accomplish these methods steps is also provided.

Assignee:

I-O Display Systems, LLC - Menlo Park CA

International Classification:

G09G 500

US Classification:

345 7

Abstract:

A system which can automatically display either regular two dimensional images or three dimensional images: The system includes, a processor which executes a program, a display, eye glasses which have electronically controllable lenses, and a detector unit connected between the processing unit and the display. Prior to displaying a three dimensional image, the processor sends a signal to the display which represents a particular bar code. The bar code indicates if the following three dimensional images will be displayed in page flip mode or in an interlaced mode. The detector unit detects the bar code and activates the special glasses so that the lenses in the glasses are alternatively opened and closed as frames are displayed. At the end of the three dimensional presentation, the processor sends another bar code to the display. The detector detects this bar code and the systems resumes normal two dimensional operation with both lenses in the glasses being open at all times.

Assignee:

Octel Communications Corporation - Milpitas CA

International Classification:

H04L 900
H04M 164

US Classification:

380 50

Abstract:

A voice message system having a plurality of user voice mailboxes is disclosed. The voice message system utilizes a method in which a message is encrypted using a unique encrypting key corresponding to a designated user. The encrypted message is then stored in one location while the encrypting key is stored in another location. The encrypted message is retrieved by the designated user by utilizing a decrypting key which corresponds to the stored encrypting key. The decrypted message is then played by the designated user.

Assignee:

OCTEL Communications Corporation - Milpitas CA

International Classification:

H04M 350

US Classification:

379 67

Abstract:

The present invention provides a highly reliable network of interconnected voice processing modules. The voice processing modules are interconnected by a high speed FDDI (Fiber Distributed Data Interface) network so that information can be transferred between the modules at high speed. All of the incoming lines for all the interconnected modules are connected in a single hunt group. Each user's profile is stored in two modules and each module includes a directory that shows were each user's profile is stored. When a call arrives at a particular module, the directory is first checked to insure that the desired user does have a mailbox somewhere on the network and to determine where the particular user's profile is located. The user's profile is obtained via the FDDI network from one of the modules where it is located. The profile will show where the associated greeting is stored.

International Classification:

H04L 1266

US Classification:

370353

Abstract:

A method and an apparatus for providing data communications over the existing telephone network without burdening the public switched telephone network (PSTN) switch with data communications traffic. In one embodiment, a novel modem is coupled to both ends of the twisted pair telephone wire which runs between a remote location and the Central Office (CO) or the remote CO. An off-hook detector is also connected to the twisted pair line in order to enable detection of when normal telephony functions are being performed over the twisted pair line. The modems of the present invention are capable of transmitting data whenever normal telephony functions are not being performed, such as for example when the telephone line is on-hook. The data transmission in accordance with the teachings of the present invention uses sufficiently low current levels such that the PSTN switch located at the CO does not detect any activity on the twisted pair line.
