1. INTRODUCTION
1.1 OVERVIEW
This manual describes the AT Commands and the S-Registers for the following
xmodus Socket Modem families:
AL5068S ISDN Socket Modem (5V Version)
AL5068S-3V ISDN Socket Modem (3V Version)
AL5068SI-3V ISDN Socket Modem (3V Version and IOM-2 bus)
The description apply to all these isdn-modems with any differences between product
families noted. Refer to Modem Firmware Release notes for commands applicable to
modem firmware.
1.2 PRODUCT DESCRIPTION
The xmodus AL5068S, AL5068S-3V and AL5068SI Socket Modem Family provides
the OEM with a complete ISDN data/voice/speakerphone modem in a compact
socket-mountable module. This modules enables any devices to send and receive
data over the ISDN network. The European EuroISDN DSS-1 ISDN network is
supported. The module is fully approved and homologated and conforms to the CE
regulations. This gives fastest time-to-market to ISDN-enable any devices.
The compact size and high level of integration of the Socket Modem minimizes real
estate and cost for motherboard and box modem applications. Its low power
consumption makes it ideal for a wide variety of embedded control applications. The
pin compatibility between the full range of Analog Series Socket Modems, ISDN and
GSM Socket Modems allows upgrading and production configurability without
hardware changes.
As a data modem, the AL5068S Socket Modem can send and receive data at speeds
up to 64kbps and 128kbps in the 2-channel version. B-Channel protocols such as
V.110, V.120, PPP, transparent and X.75 are supported.
For X.25 networks, X.31 Case A and X.31 Case B (D- and B-channel) is supported.
The integrated X.3 PAD can be used for data transfer to the X.25 network.
The AL5068SI-3V Socket Modem supports Voice features. By adding two external
PCM Codecs the modem supports two independent analog voice ports. Digital voice
transfer is also supported.

2. SYNTAX AND PROCEDURES
The command and response syntax and procedures generally conform to referenced
recommendations and standards. Since these recommendations and standards
describe characteristics universal to a large installed base of modems to a maximum
degree, there may be syntax and procedural differences due to extensions and
behavioral differences in implemented commands, parameters, and responses
beyond that described in these recommendations and standards.
The syntax and procedures described in this section are based on V.25ter with
additional information included for implemented extensions and behavioral
differences beyond V.25ter.
2.1 ALPHABET
The T.50 International Alphabet 5 (IA5) is used in this document. Only the low-order
seven bits of each character are significant to the modem; any eight or higher-order
bit(s), if present, are ignored for the purpose of identifying commands and
parameters. Lower-case characters are considered identical for their upper-case
equivalents when received by the modem from the DTE. Result codes from the
modem are in upper-case.
2.2 DTE COMMAND LINES
Words enclosed in <angle brackets> are referenced to syntactical elements. The
brackets are not used when the words appear in a command line, the brackets are
not used. Words enclosed in [square brackets] represent optional items which may be
omitted from the command line at the specified point. The square brackets are not
used when the words appear in the command line. Other characters that appear in
syntax descriptions must as included as shown.
2.2.1 Command Line General Format
A command line is made up of three elements: the prefix, the body, and the
termination character.
The command line prefix consists of the characters “AT” or “at” or, to repeat the
execution of the previous command line, the characters “A/” or “a/”.
The body is made up of individual commands described in this document. Space
characters (IA52/0) are ignored and may be used freely for formatting purposes,
unless they are embedded in numeric or string constants. The termination character
may not appear in the body. The modem can accept at least 80 characters in the
body.
The termination character may not be selected by the user, the default is CR.
Example:
AT&FE0Q1S0=1S96=1<CR>

2.2.2 Command Line Editing
The character <BS> is interpreted as a request from the DTE to the modem to delete
the previous character.
2.2.3 Command Line Echo
The modem may echo characters received from the DTE during command state and
online command state back to the DTE, depending on the setting of the ATEn
command. If so enabled, characters received from the DTE are echoed in the same
format as received.
2.2.4 Repeating a Command Line
If the prefix “A/” or “a/” is received, the modem immediately executes once again the
body of the preceding command line. No editing is possible, and no termination
character is necessary. A command line may be repeated multiple times in this
manner. Responses to the repeated command line are issued using format of the
original command line. If “A/” is received before any command line has been
executed, the preceding command line is assumed to have been empty (that results
in an OK result code).
2.2.5 Factory Settings
The parameter settings of the isdn-modem are pre-configured by the factory defaults.
This factory defaults can be reloaded at any time by using the AT&F command. The
parameter settings will be changed when using any AT commands which affects the
configuration of the modem. This changes can be permanently stored by using the
AT&W command. The factory defaults are identified for each command and in the S-
Register descriptions. A configuration (profile) consists of a subset of S-Registers.
AT&F = Restore factory configuration.
AT&W = Store current configuration.
Result codes:
OK
2.2.6 Escape Code Sequence
When the modem has established a connection and has entered on-line data mode, it
is possible to break into the data transmission in order to issue further commands to
the modem in an on-line command mode. This is achieved by the DTE sending to the
modem a sequence of three ASCII characters specified by register S2. The default
character is '+'. The maximum time allowed between receipt of the last character of
the three escape character sequence from the DTE and sending of the OK result
code to the DTE is controlled by the S12 register (default 1 sec.). The escape
characters will be transmitted transparent to the remote side.
Example: [1s pause] <+><+><+> [1s pause]
