MUX Integration
Overview
The G24 is supplied with an internal GSM 7.10 protocol stack, also referred to as a multiplexer or
MUX.
The G24 with multiplexer support utility provides the following capabilities:
Provides the terminal with up to five virtual channels on one physical RS-232 connection.
Provides simultaneous data (CSD/GPRS) and command (AT command set) services. In this
way, many applications can use a single RS232 line via virtual channels. This enables a user
to make network and phone service inquiries and maintain data communication at the same
time.
These capabilities are illustrated in the following figure:
