PROCESS AND APPARATUS FOR MULTIPLE RANDOM ACCESS TO A TRANSMISSION LINE IN A LOCAL NETWORK FOR SPEECH AND DATA |
摘要 |
The system allows the implementation of packet-switched synchronous speech communications in the network without requiring any centralized device synchronizing all the network stations. To obtain that, the active periods of each station are subdivided into frames each having a duration equal to the time elapsing between the generation to two subsequent speech packets relating to the same communication; once a station has accessed the line for the speech communications, these communications are allotted time slots which are maintained for the whole communication duration. The slots not allotted to speech communications are allotted to data transmission. The access to the line for a speech communication is obtained by the same contention techniques used also for data transmission. |
