PURPOSE:To contrive the improvement of operability and economy by extracting the sampled value of a data signal and the sampled value of a clock signal from a signal constitution received by the digital line terminating equipment at a receiving side, reproducing the data signal and the clock signal and communicating them to a data terminal equipment at the receiving side. CONSTITUTION:Since a clock signal used by a data terminal equipment 2 at a transmission side is communicated to a data terminal equipment 3 at a receiving side as well as a data signal, it is not necessary to accumulate the data signal in a digital line terminating equipment 4, the data terminal equipment 2 at the transmission side can send the data signal continuously and the operability is improved. Since sampling means 100 and 200, an assembling means 300, a dissolving means 400 and reproducing means 500 and 600 are easily realized, for example, by a register or a shift register, the economy of the digital line terminating devices 4 and 5 is improved as well. |
