Socket ISDN basic V2
Operating Principle
This chapter describes the basic procedures to operate and configure an Socket
ISDN basic V2. In general, the Socket ISDN basic V2 is configured and operated via
AT commands. You can enter these commands yourself with the help of a terminal
program and the AT command reference.
5.1
Operation with the Terminal Program
In general, any terminal program can be used. We recommend the program
TeraTerm by T. Teranishi under Windows. It is available free of cost on the
Internet at http://hp.vector.co.jp/authors/VA002416/teraterm.html. You can
use the program "minicom" if you work in a Linux environment.
Caution!
Damage of the serial interface!
A possible direct connection of the serial interface of the
Socket ISDN basic V2 with a typical RS232 interface of a
PC overloads components of the module due to the higher
voltage levels.
Use an RS232 level converter (e.g. MAX232) to adjust both
interface types correctly.
Configuring and operating the Socket ISDN basic V2 with a terminal program
How to configure and operate the Socket ISDN basic V2 with a terminal
program.

The Socket ISDN basic V2 is connected to the PC and supplied with power.

A terminal program is installed on the PC.
1.
Start your terminal program.
2.
Select the serial port, to which your Socket ISDN basic V2 is
connected.

3.
Type the character string AT into the terminal program. Complete the
entry by pressing the Enter key.


14
COM1 under Windows corresponds to /dev/ttyS0 under Linux.
Each command input starts with AT and is completed with the Enter
key.
The Socket ISDN basic V2 replies with
OK.
Socket ISDN basic V2

4.
If the Socket ISDN basic V2 does not respond, this may have three
probable reasons:
a) the Socket ISDN basic V2 is switched off or
b) the Socket ISDN basic V2 is not in configuration mode or
c) the Socket ISDN basic V2 is connected to another serial port. Check
it and repeat step 3.
Configure the Socket ISDN basic V2 using AT commands.

5.
Operating Principle
A reference of the AT commands can be found in the chapter "AT
Command Reference".
Save your entries with AT&W.

Not all configurations at the Socket ISDN basic V2 need to be saved
actively by entering AT&W. Some settings are automatically saved
immediately. We still recommend sending the command AT&W to the
Socket ISDN basic V2 as your last configuration step to ensure that all
settings are stored safely and are available for the next restart.

Functions
6.1
Establishing or Accepting a Data Connection
The Socket ISDN basic V2 can call another ISDN TA (ISDN Terminal Adapter) via
the phone line and establish a data connection. After dialling a phone number, the
Socket ISDN basic V2 synchronises with the called TA and opens a data
connection. All incoming characters are transmitted to the other (called) TA during
the active data connection. Therefore, AT commands are not processed during a
connection. The Socket ISDN basic V2 must be changed to command mode again
using an "Escape sequence" that it processes AT commands again during an active
connection. Then, the local Socket ISDN basic V2 processes the entered characters
as AT commands and does not transmit them to the remote terminal.
The Socket ISDN basic V2 can accept an incoming connection in the same way.
For this, the "application" or the PC with the terminal program must support the
hardware data flow control at the serial interface, otherwise, the Socket ISDN basic
V2 does not accept the incoming connection. In this case, the hardware data flow
control must be disabled in the Socket ISDN basic V2 that a connection is accepted
regardless of the status of the application. The Socket ISDN basic V2 answers after
the configured number of ring tones and opens a connection.
This hardware data flow control is activated by default.
Configuration with AT commands
In order to establish a data
connection with the Socket ISDN
basic V2, use the command
ATD<number>
Replace <number> with the phone
number of the remote terminal.
In order to configure the data
connection protocol, use the
command
ATB
Refer to the AT command
reference for protocol details.

Functions
6.1
Socket ISDN basic V2
Automatic call
The automatic call allows to initiate a call to a phone number previously stored in
the Socket ISDN basic V2. There are three possibilities for initiating a call.
The call may be initiated by the DTR line of the serial interface or incoming data at
the serial interface. Additionally, the Socket ISDN basic V2 can try to call a number
immediately after switching it on.
The phone number for the automatic call is taken from the dialling table "catab". If
a connection could not be established successfully, the Socket ISDN basic V2 dials
the next number from the dialling list. If none of the target phone numbers from
the dialling list could be reached, the Socket ISDN basic V2 initiates an automatic
redial. You can change the maximum number of attempts as well as the duration of
the pause until the next call.
6.1.1 Configuring an Automatic Call
In order to configure an automatic call, change to the Configurator mode of the
Socket ISDN basic V2 and enter the target phone number first, then select the
trigger for the connection establishment and set the reset timer. The reset timer
determines the time from the reset of the Socket ISDN basic V2 until the change to
the "automatic call" mode. If an automatic call is enabled, you have the possibility
to send AT commands to the Socket ISDN basic V2 during this time. The Socket
ISDN basic V2 does not accept AT commands anymore after you have configured
and enabled the automatic call. The reason for this is that incoming data are
immediately transmitted to the called remote terminal. An established connection
is indicated by the Socket ISDN basic V2 by the "OH" LED and "DCD" LED on the
housing front.
The automatic call is disabled in default setting . The dialling table "catab" is empty.
Configuration with AT commands
To start the TA+Configurator, use the
command
To configure or overwrite the target phone
number(s) of the remote terminal, use the
command
Replace <n> with values from 1 to 10 (3 for
FW < 1.027).

6.
Exit the remote configuration with the command go.
6.2
Data flow control
The data flow control ensures that the data transfer is interrupted as soon as the
buffer of the Socket ISDN basic V2 exceeds a certain level. There are two
possibilities for data flow control: via the control lines RTS and CTS, or via the
control characters XON/XOFF which are inserted into the data stream.
6.2.1 Hardware Data Flow Control (RTS/CTS)
The hardware data flow control works in two directions. When the critical buffer
level is exceeded, the Socket ISDN basic V2 will set the CTS line to "low" and will
thus indicate to the application to interrupt the data flow. When the buffer is
emptied sufficiently for the Socket ISDN basic V2 to be able to receive data again,
the CTS line is set to "high". Reversely, the application can also indicate to the
Socket ISDN basic V2 to interrupt the data flow. This is done via the RTS line. If it is
set to "low", the Socket ISDN basic V2 will interrupt the data flow to the
application. The application will set it to "high" to request data from the Socket
ISDN basic V2.
Data flow control is set to hardware as default setting.
Configuration with AT commands
Enable hardware data flow control
(RTS/CTS) with the command
AT&K=3
Disable data flow control with the
command
AT&K=0
21
Functions
Socket ISDN basic V2
6.2.2 Software Data Flow Control with XON/XOFF
When the input buffer of the Socket ISDN basic V2 exceeds a certain fill state, the
Socket ISDN basic V2 will insert an XOFF character into the data stream to the
application. This character will cause the application to send no more data. It
depends on the according application software if the XON/XOFF data flow control
is supported.
After the input buffer of the Socket ISDN basic V2 is emptied sufficiently that data
can be received again, the Socket ISDN basic V2 will send an XON character to the
application. This character will cause the application to send data to the Socket
ISDN basic V2 again. Analogously, the application can insert XON/XOFF characters
into the data stream to switch the data flow on and off. The XON/XOFF data flow
control is only available when the transmitted data do not contain the characters
XON or XOFF, which usually appear only in actual ASCII texts (7 bit). When binary
data (programs, etc.) are transmitted, or in the XMODEM transmission protocol, for
example, occasionally appearing XON or XOFF characters would disturb the
operation.
Configuration with AT commands
6.3
Enable the software data flow control
XON/XOFF with the command
AT&K=4
Disable data flow control with the
command
AT&K=0
Remote Configuration
You can configure the Socket ISDN basic V2 with another ISDN TA from remote.
You can configure a password, authorised callers as well as a remote configuration
number to restrict access. The configuration is performed via the TA+Configurator.
This is automatically started after the connection establishment for remote
configuration.
The remote configuration is active as default. No password is entered and all callers
are authorised.

6.3.4 Configuring the Permitted Callers for Remote Configuration
You can create a list with up to 3 or 10 (depending on firmware) phone numbers,
which are permitted as caller numbers for remote configuration of the Socket ISDN
basic V2. The Socket ISDN basic V2 ignores each incoming call with a phone
number, which does not match with one of the entries of the list. The Socket ISDN
basic V2 compares the number of the caller with each entry of the list for this. The
comparison starts with the last digit of the phone number. It will be compared until
an entry matches a caller number. If a table entry contains only an asterisk "*",
each incoming call is accepted. If the table is empty, the Socket ISDN basic V2
accepts each caller for remote configuration.
The list is empty as default setting.
Configuration with AT commands
In order to output the phone number of a
caller together with the RING message in
the terminal window, use the command
ATV2
In order to define the permitted caller for
remote configuration, enter the phone
number of the permitted callers in the table
racctab.
<n> is the number of the table entry and
can take on the values 1 to 3 or 10 (depending on firmware).
<callno> is the transmitted phone number
of the permitted caller.
The maximum length of the phone number
is 20 digits.
* : is a wildcard for one or more digits.
AT**racctab<n>=<callno
>
only the entered number is accepted
AT**racctab1=089123456
all numbers starting with "089123" are
accepted
AT**racctab1=*89123*
all numbers ending with "1234" are
accepted
AT**racctab1=*1234
all incoming calls are accepted, without
sub-address
AT**racctab1=*
In order to query the table, use the
command
AT**racctab
In order to delete an entry, use the
command
AT**racctab<n>=-

TA+Configurator
The Socket ISDN basic V2 has a further command set, the so-called
"TA+Configurator", besides the AT command set. This special command set is
used in a terminal program after changing to the "TA+Configurator" besides the AT
commands. The commands of the TA+Configurator can also be entered directly by
adding the prefix AT** without having to change to the special TA+Configurator
command set. The TA+Configurator is especially used for some functions of the
Socket ISDN basic V2, for example during remote configuration. A list of the
command can be found in the section "TA+Configurator Commands". The entry is
not case-sensitive.
The TA+Configurator is not active by default when operating via a terminal

Details about Multilink PPP (only Socket ISDN basic
V2 Internet)
The following authentication protocols (AP) are supported by the Socket ISDN
basic V2 Internet with Multilink PPP (ML PPP) at the moment:
 Password Authentication Protocol (PAP)
 Challenge Handshake Authentication Protocol (CHAP) with variants
 MD5 according RFC 1321
 Microsoft CHAP according RFC 2433
PAP exchanges the password in clear text format in the B channel, while CHAP
encrypts the password according to the algorithms as described in above
mentioned RFCs. For CHAP, the password must be stored in the Socket ISDN basic
V2 Internet in addition to the settings in Dial-Up Networking under Windows 95.
This is not necessary under Windows 98/ME/2000/XP.
The following basic rules are valid if the Socket ISDN basic V2 Internet is
configured for ML-PPP:
 If the remote side (in the connection control protocol LCP ConfigRequest)
requests an AP, which can be handled by the Socket ISDN basic V2
Internet, the request will be forwarded to the local side.
 If the remote side requests an AP, which cannot be handled by the Socket
ISDN basic V2 Internet, the Socket ISDN basic V2 Internet suggests the
30
Socket ISDN basic V2
Functions
safest protocol depending on the preconditions:
- PAP, if no password "chappwd" is stored locally
- CHAP/MS-CHAP MD5, if a password "chappwd" is stored locally
This step can be repeated with a certain number of attempts. Then, the
Socket ISDN basic V2 Internet falls back to single link operation until the
next connection attempt.
 As soon as the local side (with an LCP ConfigNak) refuses an AP, which
has been suggested by the Socket ISDN basic V2 Internet alternatively
(refer to previous rules), the Socket ISDN basic V2 Internet falls back to
single link operation until the next connection attempt. Local and remote
side negotiate any AP.
 The negotiated AP is cehecked at the end of the connection setup
procedure and, if supported, also used for the second connection. If the
last AP is not supported, the second connection will not be established.
The Socket ISDN basic V2 Internet falls back to single link operation until
the next connection attempt.
Please note that some hosts are very stringent. If, for example, PAP is suggested
by the Socket ISDN basic V2 because no "chappwd" password is present, the
connection is simply terminated without the chance to negotiate any other
protocol. In these cases, the Socket ISDN basic V2 Internet should be configured
for single link PPP operation or the "chappwd" password should be stored in the
Socket ISDN basic V2 Internet.
6.10
Call Bumping (only Socket ISDN basic V2 Internet)
An ML PPP connection uses both B channels of the S0 bus. In order to answer an
incoming call (i.e. a voice connection) during an ML PPP session, a B channel must
be released. This is called call bumping.
In order to allow call bumping, proceed as follows:
 Enable the call waiting function in the S0 bus. It must be enabled in ISDN
and is a service feature of your ISDN connection.
 Open the "Properties" of your dial-up connection, which you use for ML
PPP. Enter the command AT**CMLP=1 as additional parameter.
In case of a call during an ML PPP connection, the Socket ISDN basic V2 Internet
releases a B channel and an ISDN phone connected to the S0 bus can answer the
call.

Bandwidth on Demand (BOD) (only Socket ISDN basic
V2 Internet)
Selecting this function causes the Socket ISDN basic V2 Internet to use Multilink
PPP automatically to increase the ISDN data rate using the second B channel:
 If the data rate of the Internet connection exceeds a certain defined value,
a second B channel connection is established and used for data
communication automatically.
 If the data rate of the Internet connection falls below a certain defined
value, the second B channel connection will be terminated automatically.
Configuration with AT commands
In order to disable BOD (default), use the
command
ATB**BOD=0
In order to enable BOD, use the command
ATB**BOD=1
In order to define the data rate level for
establishing the second B channel
connection, use the command
ATB**BODIV=<incrValue>
Replace <incrValue> with the data rate
level in kbit/s (default: 40).
In order to specify the duration for which
the data rate level must be exceeded to add
the second B channel connection, use the
command
ATB**BODIT=<incrTime>
Replace <incrTime> with the duration in
seconds (default: 30).
In order to define the data rate level for
terminating the second B channel
connection, use the command
ATB**BODDV=<decrValue>
Replace <decrValue> with the data rate
level in kbit/s (default: 40).
In order to specify the duration for which
the data rate level must be fallen below to
disable the second B channel connection,
use the command
ATB**BODDT=<decrTime>
Replace <decrTime> with the duration in
seconds (default: 30).

Socket ISDN basic V2
ISDN Error Messages
The exact failure cause is recorded in the protocol memory of the Socket ISDN
basic V2 in case of a faulty connection establishment. Possible error messages are
described here; a complete list of the possible error messages can be found in the
subsequent table (refer to section 7.1).
Protocol error layer 1 (error code 3301)
There is no physical connection to the ISDN network. Check the cable confection
between the ISDN adapter and the ISDN port. Are you using a suitable cable? Is
the connection socket properly installed? Is the ISDN network terminator correctly
activated? Do you have other devices on your ISDN line that are maybe faulty or
that are blocking the S0 bus?
Protocol error layer 2, e.g. DTE address not valid, TEI not valid (error code 3302)
Could not connect to the ISDN network. This may be due to a wrong ISDN
protocol. Have you set "1TR6" (German ISDN) as ISDN protocol even though your
ISDN line is set up for "DSS1" (Euro ISDN). or vice versa?
Unallocated (unassigned) number (error code 3481)
"No connection under this number". The number you are calling could not be
reached because it has no line assigned to it. The phone number has the right
format. Enquire at your telephone company or the operator of your telephone
exchange what the correct number is.
Normal call clearing (error code 3490)
"Connection terminated normally". One of the users of the connection cancelled
the connection. The connection was not cancelled by the ISDN network.
User busy (error code 3491)
"Busy". The number you are calling cannot answer any calls at the moment
because all channels are being used.
No user responding (error code 3492)
The number you are calling did not answer within the time period required by your
connection. There is probably no terminal device connected to the number you are
calling. Contact the other party to establish the cause.
No answer from user (user alerted) (error code 3493)
The number you are calling confirmed call received within the time period required,
but a connection was not established, however. If the terminal device of the other
party is a telephone, then it rang, but the call was not answered. Try again later.
34
Socket ISDN basic V2
ISDN Error Messages
Call rejected (error code 3495)
The device reached under the phone number refused the call, although it was not
busy and was able to answer the call. Example: if the ISDN option "Call waiting" is
activated on the other's party line, a telephone can answer your call even if a call is
in progress at the time. This error message occurs when your waiting call is
refused by the person you are trying to reach.
Number changed (error code 3496)
The phone number of the party you are calling has changed. Contact your
telephone company for the new number.
Destination out of order (error code 349B)
The terminal device on the number you are calling could not be reached, because
the port for this device did not work. Possible causes: the other party's terminal
device is not connected or not turned on, or it is not working properly. Contact the
other party to find out the cause.
Invalid number format (error code 349C)
The party you are calling could not be reached because the number you called is in
the wrong format or incomplete.
No circuit/channel available (error code 34A2)
No B channel is available for a call at the moment. Upon this, the Socket ISDN
basic V2 initiates a blockade release and clears a B channel with this.
ISDN network out of order (errror code 34A6)
Problems in the ISDN network. Wait a while and try again.
Temporary failure (error code 34A9)
Temporary problems in the ISDN network. You can try again immediately.
Incompatible destination (error code 34D8)
The terminal device of the other party is not compatible with the terminal device
that is making the call. The call cannot be answered, therefore. This error could
occur, for example, if the terminal device of the other party is a normal telephone.

Socket ISDN basic V2
CE/EMC Compliant Integration
When integrating the Socket ISDN basic V2 into an application, the system integrator is responsible for the CE/EMC conformity of the entire device. In order to integrate the Socket ISDN basic V2 CE and EMC compliant into your application, we
recommend the following for you to observe during development.
13.1
Your Application
 The motherboard for the module must be designed according to the
applicable CE/EMC guidelines. Always observe short signal lines and
sufficient ground surface.
 If you develop a platform, which is compatible with several, different
modules, you must maintain the respective design criteria for each module
(especially concerning the phone connection).
 The PCB tracks to the modules with network interfaces, like Modem, ISDN,
and Ethernet, must be designed with a track distance of 2.5 mm between
the tracks of the network interface and all other signals (refer to EN60950).
13.2
Application Interface / Pin Connector X4
 The TTL RS232 interface should be equipped with ferrite beads directly at
the module to reduce interference signals from the motherboard.
 It is also beneficial to design capacitors (preferably SMD) at all RS232 and
I/O signal lines to GND, which can be equipped when needed. Short lines to
the connector and good ground are important. The recommended value for
capacitors is 22 pF to 47 pF.
13.3
Network Interface / Pin Connector X5 (for Modem
/ISDN)
 The line to the network interface (line from module to device socket) should

be as short as possible and not be routed close to sources of interference
(e.g. switching power supplies).
Provide the line with ferrite beads directly at the device socket.
The phone interface (not for module with Ethernet interface) should be
provided with standard ferrite beads (e.g. Murata BLM31A601SPT or Würth
Elektronik type 74279213) and with optional ceramic capacitors
(100 pF/2 kV, Y2 standard) to ground.
In case of extended requirements to the interference resistance of the phone
line (especially burst), a current compensated impedance (e.g. Epcos
B82790-C2475-N340 or Würth Elektronik type 744202) can be used.
The strip conductors on the Ethernet side should have a wide design
(minimum 24 mil).
Ethernet receive PCB tracks must provide a minimum width of 25 mil,
Ethernet transmit PCB tracks a minimum width of 100 mil (1 mil ≈

0.0254 mm). The PCB tracks must be routed parallel and have the same
length.
13.4
Antenna Connection (if equipped)
 The antenna connection must be connected to ground and a ferrite ring
must be installed behind the ground connection (towards module) to
increase the interference resistance against burst and ESD at the antenna
connection.
13.5
Further Recommendations
The required measures will mostly depend on the connections and the layout (especially of the ground surfaces and good ground connections) of the motherboard.
To save costs, some of the above mentioned capacitors or ferrite beads may be
omitted. However, they should be considered in the layout to be able to integrate it
without having to change the PCB, if the EMC tests show that these components
are necessary. For the Ethernet module, insert bridges instead of the ferrite beads,
while the ceramic capacitors remain unequipped.
