A method and simultaneous voice/data transmission of signals through a single communications channel wherein the transmitted voice and data signal quality is greatly enhanced over current practice. A time-varying stream of coded voice and data signals is simultaneously transmitted and the sequence of transmitted data signals is determined only after receiving data signals for a predetermined period of time. The received signals are buffered and a received coded data signal sequence is compared to a predetermined plurality of permissible coded data signal sequences to correlate the received coded data signal sequence with the particular permissible coded signal sequence with which the data signal was coded prior to transmission. The correlated data signal sequence is then separated from the combined voice and data signal to recover the coded voice signal. The recovered voice signal and correlated data signal sequence are thereafter decoded to recover the voice and data signals that were received and coded by the transmitter.

A number of arrangements and methods that achieve concurrent communication of analog information and digital information. In general terms, when the communication channel is viewed as a multi-dimensional space, the digital information signal is divided into symbols, and the symbols are mapped onto the signal space with a preset distance between them. The analog signal, generally limited in magnitude to less than half the distance separating the symbols, is converted to component signals and added (i. e. , vector addition) to the symbols. The sum signal is then transmitted to the receiver where the symbols are detected and subtracted from the received signal to yield the analog signal components. The transmitted analog signal is recreated from those components. Arrangements utilizing the above principles are applications where systems that include a digital port can benefit from an analog communication channel, and conversely, where systems that include an analog port can benefit from a digital communication channel.

A multiple line modem and method enable a user to automatically usurp a plurality of telephone lines for data transfer when the telephone is not in use and the ability to switch from multiple line data operation to one (or more) line data and one (or more) line telephone operation automatically when the telephone handset is lifted or an incoming call is detected signaling a request for voice service. The multiple line modem will automatically reestablish the data connection on the line(s) that was used for voice service when the voice service terminates. The multiple line modem allows end to end service that is transparent to the central office. When all lines are operating in data transfer mode, the aggregate data transfer rate is multiplied by the number of lines available for data transport. When one line(s) is operating in voice service mode, the other line(s) maintains data transfer operation at a reduced rate. The line(s) that is used for voice service is adaptively managed by the multiple line modem to provide seamless switching between data transfer mode operation when voice service is not requested and voice service mode operation when voice service is requested.

A simultaneous voice and data modem coordinates the storage of voice messages and data messages on an audio answering machine and a personal computer, respectively. This allows the called party to subsequently retrieve, via the simultaneous voice and data modem, both a voice message and an associated data message, i. e. , a multimedia message, where the called party listens to the voice message while viewing the data message. The called party can retrieve the multimedia message either locally or from a remote location.

In a system in which data between a master and remote location is encrypted by using the DES algorithm, the status of security devices at the remote location is monitored from a centralized security station. A message indicative of the status of the security devices is used to generate an initializing vector (IV). This IV is then used to encrypt the data from the remote to the master.
