Abstract: A call management method and system. The system includes at least one user position, comprising a computer workstation and a telephone apparatus that is associated with the computer workstation. In addition, the system includes a call management computer comprising a memory; and a digital data network to connect the computer workstation with the call management computer. The memory is used to store a plurality of call processing rules that determine how a call, directed to a user, is to be processed. The plurality of call processing rules is defined by the computer workstation before the call is received. The call management computer intercepts the call, that is incoming, to a first user position that is included in the at least one user position. The call management computer determines that the call is for the first user position and interacts with the memory to determine how the call is processed based on the plurality of call processing rules.

Abstract: A Call Management System provides for management of calls directly by system users at their workstation computers via a digital data network such as a digital networks not controlled via the user's telephone instruments as in prior systems. A call management computer intercepts incoming calls and controls the handling of such calls according to instructions received from the users' workstations, which are accessed via the digital data network. Trunk circuits are monitored and controlled using digital signal processors to proactively identify the called party, the calling party and the call type (voice, Fax, data) and control and to monitor all calls. Each different type of call is managed differently and automatically through direct user workstation controls and/or user-generated rules to provide special treatment for designated callers. Multiple calls to user at the same time may be handled with no busy signals to callers. Only one number is needed for a user to receive voice Fax and data calls.

Abstract: A system and method are disclosed for preventing intelligible interception of information signals transmitted over a two-direction line. A masking signal is applied through a hybrid circuit at the receiving end of the line, and this masking signal, which appears on the line together with the information signal, prevents intelligible decoding. Only at the receiving end of the line, where the hybrid circuit attenuates the masking signal which it receives at its receive port, can intelligible decoding take place. Signal processing techniques used at the receiving end permit larger amplitude masking signals to be used, thus creating even greater confusion for an unauthorized detecting mechanism which is coupled to the line.

Abstract: A technique for inhibiting intelligible interception of information signals transmitted over a line from a first site to a second site. A masking signal is applied to the line immediately upon the detection of the information signal at the second site, but prior to the time at which the validity of the signal is verified. As long as the information signal remains on the transmission line, the masking signal is repeatedly turned on and off to thereby inhibit decoding of the signal by an eavesdropping device.

Abstract: A system and method are disclosed for preventing intelligible interception of information signals transmitted over a two-direction line. A masking signal is applied through a hybrid circuit at the receiving end of the line, and this masking signal, which appears on the line together with the information signal, prevents intelligible decoding. The masking signal includes a series of frequencies which are sequentially applied. Only at the receiving end of the line, where the hybrid circuit attenuates the masking signal which it receives at its receive port, can intelligible decoding take place. The amplitude of the information signals is sensed at the receiving end and the amplitude of the masking signals on the line is adjusted to be great enough to provide security, by confusing an eavesdropping detector, yet small enough at the receiving end so that the receiving detector is not confused.
