All information provided in this section applies to the ASC0 interface only. The second interface ASC1 has no

support of Multiplex mode.

Multiplex mode according to the ETSI TS 101 669 and GSM 07.10 enables one physical serial asynchronous

interface to be partitioned into three virtual channels. This allows you to take advantage of up to 3 simultaneous

sessions running on the serial interface. For example, you can send or receive data or make a call on the first

channel, while the other two channels are free to control the module with AT commands.

The TC63 module incorporates an internal multiplexer and thus integrates all the functions needed to implement

full-featured multiplex solutions. For the application on top, customers have the flexibility to create their own mul-

tiplex programs conforming to the multiplexer protocol. To help system integrators save the time and expense of

designing multiplexer applications, SIEMENS AG offers WinMUX2k, a ready-to-use multiplex driver for Windows

2000 and Windows XP. Another approach is to develop customized solutions based on the sources of the

WinMux2k driver.

 which provides a detailed description of the multiplex architecture and step-by-step instructions of

how to install and configure the multiplex mode. The WinMUX2k driver and its source files can be supplied on

request. Please contact your local distributor to obtain the latest installation software and user's guide.
