Atm adaptation layer validating the atm header
Typically, internet data is transmitted between the personal computer and an internet service provider over a PSTN access line, as illustrated in .
However, as one skilled in the art will readily appreciate, there are numerous techniques available for improving bandwidth.
Moreover, the second sequence of minicells and the first sequence of minicells are transmitted over the PSTN access line simultaneously.
 The present invention involves multiplexing and simultaneously transmitting both voice data (e.g., telephone generated speech data) and non-voice data (e.g., computer data such as internet data) using a single PSTN access line, as illustrated in from the various components at the transmission end to the components at the receiving end in a format that is substantially similar to asynchronous transfer mode (ATM).
Consequently, the personal computer must share the PSTN access line with one or more telephones located in the household or office, as illustrated in .
Furthermore, the telephone may not be used if someone in the household or office is already using the personal computer to access the internet.
A first sequence of minicells associated with the first end-user is generated, and a second sequence of minicells associated with the third end-user is generated.
