MUX Operation

The SMC modem cell module is supplied with an internal 3GPP 27.10 protocol stack, also referred to
as a multiplexer or MUX.

The SMC modem 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/1x data call) 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.

The SMC modem with the MUX feature ENABLES multiple channel operation and simultaneous data
and control operation. For example, it allows a user to be connected to an Internet website (DATA
session connected), receive a file via CSD Call, and query the Smc modem phone book all at the
same time.

The following actions are enabled during a data session:

Incoming call alert string RING (while SMC modem is in DATA session)

Answering to incoming call via the ATA command (while SMC modem is in DATA session) SMC
modem MUX Integration

Receive Incoming SMS indication

Inquiry NW coverage indication

Setup a voice call (while SMC modem is in DATA session)

Send & Receive SMS

Read/write to/from Phone Book

Local modem operation

Network interrogation and settings

Please refer to the Motorola C24 Developer’s Guide, AT Commands Reference Manual

[1]

for more

detailed information regarding the implementation of the MUX feature.
