摘要： 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.

摘要： A communication device for use in a non-self synchronizing scrambling (NS3) communication system and a method for using NS3 in a communication system are disclosed. A digital data stream is scrambled by modifying the digital data stream based on a pseudo-noise sequence (PNS) to produce a scrambled digital data stream. The PNS has a timing reference that is distinct from the digital data stream. The scrambled digital data stream is capable of being descrambled by performing an inverse modification, based on the same PNS and the same timing reference. The scrambled digital data stream may be transmitted over a communication medium and descrambled at the opposing end of the communication medium. Synchronization between the scrambler and the descrambler is maintained by providing a common timing reference to the scrambler and the descrambler. The common timing reference is distinct from the data stream. The invention can be used on any communication system in which all the communication devices have a common timing reference.

摘要： A phase tracking loop is provided for a digital modem. The phase tracking loop rotates the equalized output of the modem by a phase corrector angle generated by a phase error detector, frequency offset integrator and phase corrector integrator. The phase error is obtained by complex multiplexing the coordinates of the received signal with a phase corrector number. The first integrator operates on the sum of the detected phase error. The second integrator operates on the sum of the output of the phase detector and first integrator. The second integrator output comprises the phase corrector angle.

摘要： A modem is provided which allows two independent sets of multipoint users to share a common communication media such as a telephone channel. At each site there is provided a modem which transmits and receives two independent frequency division multiplexed data streams simultaneously over a common telephone channel. Each data stream is encoded into an eight phase PSK or QAM signal. One data stream signal is transmitted in a low frequency range and the second is transmitted in a high frequency range. Means are provided at each site to combine the data streams for transmission over a single communication line and to separate the received combined signal from the communication line.

摘要： Systems and methods are provided for communicating data over a subscriber loop using a modem. One such method includes: transmitting data on the loop in a first frequency band; sensing an indication that simultaneous transmission on the loop in a POTS frequency band is imminent; and adjusting transmit power in the first band, in response to the sensing step. One such system includes an input/output connection in communication with the loop, a processor operable in at least two states, a means for sensing demand for simultaneous usage of the loop, and a means for controlling the state. The first state is characterized by a first transmit power spectrum in the first band. The second state is characterized by a second transmit power spectrum in the first band, reduced relative to the first spectrum. Upon sensing demand, the control means causes the processor to operate in the second state.
