Abstract
A transmission line sampling circuit for a T1 line is disclosed. A multi phase oscillator is connected to a plurality of state machines which are connected in parallel to a transmission line. The use of a plurality of state machines to sample the transmission line effectively increases the sample rate of the transmission line beyond that which can ordinarily be supported by a single phase oscillator running at the same frequency of the multi phase oscillator. The outputs of the plurality of state machines are provided to an arbitrator and to a MUX wherein the arbitrator decides which of the four state machines outputs should be switched through the MUX and produced transmitted on an output line.
