<p>PURPOSE:To prevent an operation from being affected by crosstalk by operating the burst timing synchronizing means of an intra-office equipment synchronously with a received burst timing signal when a subscriber's private equipment extracts crosstalk burst timing and sends the burst timing signal before starting communication. CONSTITUTION:When a crosstalk signal to a subscriber's private equipment 10 is generated, this signal is extracted by a crosstalk burst timing extracting means 13. The output from the crosstalk burst timing extracting means 13 is transmitted from a burst timing signal transmitting means 14 to an intra-office equipment 15. This signal is received by a receiving means 16 of the intra-office equipment 15 and the burst timing signal of the received signal is extracted by a burst timing synchronizing means 17. In such a case, the burst timing synchronizing means 17 controls the phase of following burst timing by the phase of the received burst timing signal. Thus, without unifying the burst phase between stations, the communication can be prevented from being affected by the crosstalk.</p> |
