> 3.4 | Bandwidth of Logical Channels

> Multiplex mode according to the GSM 07.10 multiplexer protocol encapsulates data and AT commands into packets which may vary in length. Each packet begins with a header carrying protocol information.
> The module’s bandwidth is shared equally among all channels. This way, a large data transmission on one channel will reduce the overall bandwidth and cause a transmission delay on the other two channels.
> Example: If the ASC0 interface is, for example, configured to 115200 bps bit rate, and GPRS connection requires, 5 kBps on one channel the other two channels will have to operate at approximately 4 kBps altogether.
> If three large data transmissions are running simultaneously while the ASC0 is set to 115200 bps, it is possible that approximately 3 kBps are available for each channel.
