Serial / Indicator Interface:
DTE serial interface and indicator outputs are supported.
Serial Interface: 8-line TTL logic serial interface to the DTE is supported.
LED Interface: Four direct connect LED indicator outputs are supported
The terminal (DTE) baudrate is determined automatically by the MCU
firmware. It provides autobaud from 9600bps to 115200bps.
The terminal (DTE) character format is fixed to 8 bits, no parity and 1 stop bit.
There is no setting required for the DTE character format.
ISDN Line Interface:
The AL5068S Socket Modem family connects to the ISDN network S
0
Interface (spec. I.430). It supports the EDSS-1 (EuroISDN) protocol stack for
network access.
IOM-2 Interface:
The AL5068SI-3V modem provides the IOM-2 bus. External PCM codecs
can be connected to use analog voice interfaces (see application notes).
2.7 Power consumption and power down modes
To reduce power consumption of the AL5068S, a power down mode can be
activated by the AL5068S. The following values are approximate power
consumption values in the different states:
Condition Power
usage
Power down
~ TBD
ISDN active
~ 27 mA
2.8 Command Sets and S-Registers
Modem operation is controlled by AT and S-Register Commands issued by the DTE.
Refer to the
AT commands for the AL5068S Modem Reference Manual
