摘要 |
Voice and data traffic are transported over a digital subscriber loop by multiplexing one or more plesiochronous packet data channels together with lower priority asynchronous traffic into a single composite data stream for transmission over the loop. The plesiochronous data packets each comprise a number of bytes together with a header element containing channel identification information and a packet length indicator. Each plesiochronous data packet is assigned a transmission time such that the desired nominal data rate for the plesiochronous channel is achieved when packets containing the preferred number of bytes are transmitted at the preferred time intervals.
