ABSTRACT:
The conference circuit provides for establishing a conference call between three conferees in a T-S-T digital switching network. The voice samples of the three conferees are sequentially stored in input buffers. When all three conferees' samples are stored, the samples are transferred to working buffers, while the input buffers store three other conferees' samples. In the time slot succeeding the transfer to the working buffers, two conferees' voice samples are compared. During the next time slot, the resultant of the comparison is transmitted to the third conferee. This conference arrangement provides for time sharing up to 64 three-port conference calls via the switching network.
