Method and apparatus for reformatting and retiming digital telecommunications data for reliable retransmission via USB |
摘要 |
A method for retiming digital telecommunications data received by a digital logger from a plurality of T-carrier type telephone lines respectively having differing clock sources ensures efficient transmission of received digital audio data to a host computer via a Universal Serial Bus (“USB”) interface. Also the digital logger includes volatile memory for temporarily storing digital audio data received from the plurality of T-carrier type telephone lines for:
1. ensuring that the host computer receives digital audio data correctly via the USB interface;2. buffering the digital audio data within the digital logger during interruptions in transmission of digital audio data from the digital logger via the USB interface; and3. reducing audible latency of speech communications. |

1. A digital logger for:
a. receiving digital telecommunications data that includes digital audio data from at least one T-carrier type telephone line; and b. retransmitting received digital audio data via a USB interface,the digital logger comprising volatile memory for temporarily storing digital audio data received from the at least one T-carrier type telephone line wherein to reduce the audible latency of speech communications:
a. an amount of volatile memory used for temporarily storing digital audio data received from the at least one T-carrier type telephone line is resized and emptied automatically; and b. clock rate is dynamically shifted slightly before transmitting digital audio data from the digital logger via the USB interface. |
