1.1 Product description
The ISDN - interface is an ISDN terminal adapter with the following functions. You
can see it as a digital replacement for an analogue modem.
• The ISDN - interface connects devices with a serial port to the ISDN. It gives
access to other devices connected to the ISDN network.
• Data can be transmitted either over the D- or B-channel with the following rates:
- by using the transmission method V.110 or V.120 in B channel.
- by using the transmission method X.75, PPP or HDLC in B channel.
- call a host connected to the X.25-network (X.25 in B or D channel).
- call a host connected to an ISDN-X.31 subscriber line
• Data can be transmitted either over the D- or B-channel with the following rates:
- Transmission via D-channel with 9600 bps (X.31-D)
- Transmission via B-channel with 64000 bps (X.31-B)
• The connected device can drive the ISDN-ADAPTER by using
- asynchronous PAD (X.3) commands
- asynchronous AT commands
- automatic call

Data Forwarding Characters
5
ISDN manual
This parameter defines a control character to be used as the Data Forwarding
Character. This character can be used to force the transmission of the collected data
to the other end, even when the defined packet size has not yet been reached.
Valid Parameter Values:
0
Only send full packets, thus no Data Forwarding Character
Regardless of the value set in parameter 3, the data packet will always be forwarded
under any of the following conditions:
when the input buffer holds a full data packet (128 bytes) and
parameter 15 is set to 0 (zero)
when the input buffer is full (512 Bytes) and parameter 15 is set to 1 ;
in this case, one data packet will be sent and the remaining data will be
shifted forward in the input buffer
after the first character of a PAD command is entered
following the entry of the BREAK signal (command INTD) - also see
parameter 7
after the timeout of the timer set with parameter 4
4
Timer for Data Forwarding
Defines the timeout interval, following which the collected data will be sent as a data
packet even if the defined packet size was still not reached.
The timer is reset each time a data packet is sent, even if it was sent as the result of
the Data Forwarding Character (see parameter 3).
Valid Parameter Values:
0
No timeout, thus no time interval
1
Immediate transfer, thus each character is immediately transferred as
a data packet.
n
n time interval in units of 50 msec. (1/20 of a second) and the value
must be an integer in the range from 2 to 255.
Example: n = 40 => time out interval of 2.0 seconds
A data transfer timeout is only permitted, when parameter 15 is set to 0
(zero).

2.2 AT command set
All parameter can be changed by using an extended AT command set described in
this chapter.
Please check if the factory setting will fit with your environment. The factory setting is
described (highlighted) in the parameter list shown in chapter "AT command set"
(see below).
If you want another configuration as set in the factory default setting, please do the
following steps:
•
•
•
•
•
•
Connect the ISDN - adapter to ISDN interface
Connect the PC's com-port to the DTE interface of the ISDN-ADAPTER.
Connect the power supply to the mains socket.
Start a terminal emulation on your PC, please verify that the baudrate setting
of the terminal emulation fits those of the ISDN - adapter.
Set up the parameter of the ISDN - adapter from the terminal emulation and
save the parameter using the AT command set.
Example:
To change the used B channel protocol to X.75 please enter the
following commands:
ATB10<↵>
(set protocol to X.75)
AT&W<↵>
(save the new configuration)
Leave your terminal emulation and start your application program.
With the exception of the command A/ (Repeat command) all commands begin with
the prefix AT and are terminated with <↵>. Corrections in a command line are done
with <BACKSPACE>. A command line has a maximum of 80 characters (up to 140
characters using “UUS1”. The command line is automatically cancelled by longer
input. Blanks are ignored, capital/small letters are not significant.
The parameter settings of the ISDN-ADAPTER obtained when using the AT
commands can be permanently stored (AT&W) and are not lost by resetting or by
leaving the AT command mode.
© AK-Nord
14
ISDN manual
To enter the AT command mode during an active data connection you must use the
following sequence ("Escape sequence"):
1.
<delay time according to S12 register>
2.
<+><+><+>
3.
<delay time according to S12 register>
The time gap between all three plus signs may not exceed 1 sec.
The escape sequence is transmitted transparent to the remote device.
Note: If B channel protocol PPPasync (ATB3) is selected, the escape sequence has
to be included in an asynchronous HDLC frame. The coding of the complete
asynchronous sequence is: 7E 2B 2B 2B 1B B4 7E.
The timeout after sending the "escape sequence" <+><+><+> will increase in
terms of the configuration parameter "txfwd". The default value of "txfwd" is
set to "0" (“0” = 4 character timeout).
If "txfwd=100" (equals 1 second), the timeout of receiving the "OK" message
will be around 2 seconds.
Supported commands:
A/
Repeat last command line
This command repeats the commands of the last entered command line.
Note: No prefix AT is required.
A/
A
Accept incoming call
Using this command you can accept an incoming call, if automatic call acceptance is
not set (Register S0 = 0). An incoming call is displayed by the message “RING“ or
the code “2“.
The time interval to display the incoming call (“RING” or “2”) can be configured with
the S-register S80. The default value is set to “S80=50” which is equivalent to 5
seconds.
The serial status line "RI" will toggle during the active "RING" state uniformly
distributed according the half time of register S80.
This command must be the last command in an AT command line.

2.3 Serial status lines
The behave of the output serial status lines DSR, CTS, DCD, RI and the input serial
status lines DTR, RTS can be configured as described in chapter 3.1 and 4.1 to 4.3.
After power on all serial status lines from the TA will be inactive.
The serial status line DSR can be configured to signal the activation of the current
command set (cdsr=0). When changing the command set (cmds) the DSR line goes
off during this change phase.
The serial input status lines DTR and RTS will be controlled of an interrupt in the TA
firmware. With regard of this behave the maximum input level change must be lower
than 100Hz (10ms steps).
The V.24 control circuits will be described for the three different states:
no connect phase: The TA has no ISDN connection.
The serial data (commands and responses) will be used to
configure the TA (command mode).
dial phase:
The TA has started to establish an ISDN connection and is
and
waiting for the synchronization.
disconnect phase: The TA disconnects the existing connection (B-channel and Dchannel connection).
connect phase:
ISDN data connection is established (D-channel and B-channel
connected).
Serial data will be sent or received according to the configured
B-channel protocol (data mode).

DTR line will be considered
Outgoing calls:
The DTR level will be considered.
DTR off in the command mode refuses the call procedure
with ERROR.
Incoming calls:
Incoming calls will be accepted only when DTR is ON.
The incoming call request can be refused with changing
DTR to off.
Disconnection:
DTR drop disconnects an active connection
or a call during the dial phase.
If DTR will be dropped immediately after sending serial
data there is no guarantee to transmit these data to the
destination side.
A delay of (configured "txfwd" time + 10ms) between
sending the last data byte and dropping the DTR line would
send out the last data stream.

DTR ignore and DTR drop disconnects
Outgoing calls:
The DTR level will be ignored to establish a connection.
Incoming calls:
Incoming calls will be accepted independent of DTR status.

If the TA activates the flow control (CTS=off) the TA will buffer up to 256 bytes
from the DTE device.
If the connection will be cleared with DTR=off during an active flow control
CTS=off) the current connection will be cleared after a short timeout.
The received serial data from the DTE during the connection will be erased after
clearing the connection.
The control lines to indicate the active connection (DCD) and the "off hook" state
(DSR) will be changed without recognizing the current flow control state.
RI:
Ring indicator
The serial status line RI gets active during an incoming call request.
If the incoming call will be accepted or the call request ended the RI control circuit

2.4 Automatic call establishment
Automatic call establishment is available in the following modes:
• An automatic call will be initiated when the control line DTR is on
• An automatic call will be initiated when serial transmit data (character) received
into the terminal adapter
• Automatic connection establishment independent of any status line.
To enable automatic call you have to set TA+configuration parameter cmds to 6, 7
rsp. 8 (see below). With changing this parameter the baudrate has be set to a fixed
value (‘br’ not equal to ‘0’).
An established connection will be indicated by a status line. See also configurations
commands cdcd and cdtr.
If a connection cannot be established successfully an automatic retry will be started.
The duration of trying to establish the connection and the pause for next retry can be
configured.
The dialed number is taken from the parameter catab1.

2.5 Using Multilink PPP (option)
To enable Multilink PPP handling within the TA please enable protocol ML-PPP:
ATB31 rsp. prot = 31.
ML-PPP may be used with two different authentication protocols during the link
establishment phase:
• PAP (password authentication protocol, RFC 1334),
• CHAP (challenge handshake authentication protocol, RFC 1994) with variants
• MD5 according to RFC 1321,
• Microsoft Chap according to RFC 2433.
The simpler PAP transmits the user password as clear text over the line, whereas
CHAP uses encryption. Which protocol is actually used depends on
•
•
the local PC: if the dialup network configuration requests password encryption
only CHAP will be used,
the remote host configuration: it may (e.g.) allow both PAP and CHAP, CHAP
only etc..
2.5.1 Restrictions on Windows95
The CHAP protocol requires that the local side (PC or TA) responds with the proper,
encrypted password when ever requested by the remote host. Since Windows95
does not respond on repeated requests CHAP can be used on the second link only
if the TA knows the password. It must be stored in the TA’s NVRAM:
•
•
Enter “at**chappwd=<password>” to input your password in the TA.
Warning: The input echo is shown in clear text, it should be hidden from
unauthorized persons. Nevertheless, commands as “AT&V1” display the
password as a sequence of asterisks (“*”).
Enter “AT&W” to store the setting in the TA.
If the password chappwd is not stored on the TA (or is wrong) and remote and/or
local dialup network configuration require password encryption, the second link will
be physically established for a short time, and will then be disconnected. As a
consequence the Multilink option is disabled for the current connection.

2.5.2 Bandwidth on demand ("BOD")
Enabling this feature will cause the ISDN-ADAPTER to use the Multilink PPP
protocol to enhance the ISDN throughput using the second B channel automatically:
• if the throughput of the internet connection is higher than a definable value a
second B channel connection will be established automatically and used for data
transfer.
• if the throughput of the internet connection is lower than a definable value the
second B channel connection will be disconnected automatically.

3 TA+Configurator command set
The settings of the ISDN-ADAPTER for the serial interface and the S bus interface
are called configuration. The ISDN-ADAPTER is delivered with a set of pre-set
values. In the following section it will be shown how, by using the configuration
commands, you can examine the configuration of the ISDN-ADAPTER and if
necessary change it. The values can be stored in non volatile memory; this means
they'll remain unchanged even if the power supply is disconnected.
You can configure the ISDN-ADAPTER in the following ways:
• by using TA+ configuration commands entered by a locally connected PC.
• by using TA+ configuration commands entered via the ISDN access (remote
configuration).
• by using the PAD (X.3) command set entered by a locally connected PC.
• by using the AT command set entered by a locally connected PC.
The TA+Configurator can be entered in the following ways:
• remote via ISDN (see page 38).
• by using a special command from the asynchronous dialup command interface
(PAD: “CONF” or AT: “ATCONF”).
• or escape sequence in power up phase if enabled (rsttim>10, rstmsg=1).
3.1 Configuring the ISDN-ADAPTER with AT commands
To execute one TA+configuration command cmd out of the AT command mode you
have to issue the command: "at**cmd" .
To call up the TA+Configurator please use the command "atconf".
You can leave the TA+Configurator by the command “quit” (or „exit“ or „go“).
Note: After altering one of the profile values marked by (#1) you have to give the
additional commands save and go. This is necessary to save and activate
these new parameters.
3.2 Configuring the ISDN-ADAPTER with X.3 PAD
To execute one TA+configuration command cmd out of the X.3 - PAD command
mode you have to issue the command: “exec cmd” .
To call up the TA+Configurator please use the command “conf”.
You can leave the TA+Configurator by the command “quit”.

3.6 Software update
The ISDN-ADAPTER uses a Flash-EPROM for software updates to store the
operational software. This software can be updated from a local connected PC via
the COM port. Please fulfill the following steps to update the ISDN-ADAPTER:
•
•
•
•
•
•
•
•
Start a terminal emulation on your PC with the capability to run an X-MODEM file
transfer (i.e. HyperTerminal).
Enter the AT command "AT**FLASH" to start the update procedure.
The ISDN-ADAPTER will send the message "Erasing flash EPROM now. Please
wait...".
After erasing of the Flash-EPROM the TA send out the request of the download
procedure with the 1kX-MODEM protocol:
"Start your XMODEM transfer now (Ctrl-X aborts) ..."
Start the 1kX-MODEM file transfer (send file or upload) by selecting the Transfer
/ Send File menu point in your terminal emulation and select the new software.
The internal timeout of each X-Modem block is set to 10 seconds.
After completion you will get the information whether the software update ended
successfully or erroneous.
- Positive result:
- "Loading procedure ended successfully".
- Negative reason:
- "Checksum error." (for example)
Negative result:
- "Flash EPROM software is probably not executable".
The loaded new firmware will automatically start after a software reset.
(Give the TA about 15 seconds to activate the new software.)
Due to new functionality the last stored configuration setting may be lost, please
check before using.
Note:
Due to an error it may be that no firmware is active within the TA. This will be
indicated by flashing of the LEDs (Bootloader active). To store a new
firmware correctly you have to enter the command "AT**FLASH" again and
load a firmware using the XMODEM protocol as described above. This
bootloader supports only AT**cmd with a fixed baudrate of 115.200 Baud.

4 Diagnostic and error messages
For the diagnostic of erroneous situations the following functionality is supported.
Please check first the behavior of LED displays, if an ISDN connection can not be
established. Refer to list of LED displays on page Fehler! Textmarke nicht
definiert..
4.1 Error messages from AT command set
In AT command mode, error cause display (does not belong to the AT command
standard) can be turned on by issuing the command ATW1. The shown error causes
use the coding defined by the CAPI definition. ISDN error causes from the ISDN
network are always coded as 34xxH, where xx represents the hexadecimal version
of the ISDN error cause (see page 62). All other causes are CAPI error causes (see
page 70).
Error cause display:
<xx> = ISDN release (error) cause, hexadecimal
Example:
Tx data
ATW1
Rx data
OK
ATD12345
NO CARRIER <34A2>
4.2 Error messages of the integrated PAD
For the diagnostic of erroneous situations - e.g. no X.25-connection possible - the
following error indicators are supported.
If an error occurs during the establishment of an X.25-connection, a reason for the
failure of the connection establishment or the release of an established connection
will be indicated in accordance to the configured indication type.
See parameter 6: Indication according to ITU, Datex-P, with English extension.
The following error indicators are supported:

Error codes during establishment of an X.25-connection:
Indication as part of the Connection-Release-Message.
E.g.: "CLR OCC diag" or
"CLR DER 0 <zzzzH>"
or
"Datex-P: connection released"
or
"connection released, reason xx diag yy [<zzzzH>]".
xx shows the hexadecimal coding of the X.25 release cause and
yy shows the hexadecimal coding of the diagnostic.
zzzz shows the hexadecimal coding of the CAPI cause.

ISDN manual
4.6 Diagnostic using the internal Trace
For more sophisticated debugging an internal trace functionality is implemented.
This logging mechanism allows to write activities of the ISDN and the serial interface
into a wrap around buffer. The type of entries can be selected by a trace mask.
trcmsk
trcmsk par
set trace mask
Setup the mask to select the type of data to be written into the trace
buffer.
Default: D channel Layer 1 and 3, DTE interface lines, DTE-Data in
connection-setup and clearing-phase.
The parameter par has to be setup in the following way, all bytes have
to be entered (default 00 00 00 77 00 72 05 02):
par := bl1 bl2 bl3 dl1 dl2 dl3 sl1 app

8xxx : outgoing event (to ISDN line)
“FFFF“ : Reset for firmware
Length of following data bytes
Data bytes; continued lines are indicated by an “>“.
