ERMINAL ADAPTOR INTERFACE FOR DATA SERVICES
9.1.5.1
General description
In Fig.19 the block diagram of the data service architecture
using the PCF5083 is shown. The GSM terminal is
connected to an external terminal adaptor via the IOM
-2
interface (serial port Y) of the PCF5083. Channel coding in
accordance with “GSM recommendation 05.03”is done by
the DSP, rate adaptation and e.g. Hayes command
handling is done by the terminal adaptor.
There are two types of information that have to be
exchanged between the terminal adaptor and the GSM
terminal:
1.
User data that has to be transmitted via the air
interface. This is the input and output of the channel
codec in the PCF5083
2.
Control data which has to be exchanged between the
System Controller and the terminal adaptor.
Data transfer via the IOM
-2 is done in form of data
frames. Each data frame contains 160 16-bit samples
(20 ms) and consists of a user data block containing user
data to/from the channel codec and a control data block
containing control data to/from the System Controller. The
DSP firmware (the procedures MP_read_data_frame and
MP_write_data_frame, see Section 9.3.1) performs
multiplexing and demultiplexing of user and control data.
Control data is forwarded to the System Controller or to the
terminal adaptor, respectively without modification or
interpretation by the DSP.
A fully integrated solution for the architecture of GSM data
services is in preparation, at which rate adaptation is
realised as an additional DSP software module, Hayes
command interpretation is part of the P90CL301 software
and data communications are done via the RS-232 port of
the P90CL301.
