1.1 Product description
The TA+POC is an ISDN terminal adapter with the following functions. You can see
it as a digital replacement for an analogue modem.
• The TA+POC 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 TA+POC by using
- asynchronous PAD (X.3) commands
- asynchronous AT commands
- automatic call
To work with TA+POC you need
• an ISDN Basic Rate Interface (BRI) (replacing an analogue telephone line). The
basic rate access can be ordered by your local telephone company or PTT.
• a PC with a terminal emulation to configure the TA+POC

3.2 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 TA+POC to ISDN interface
Connect the PC's com-port to the DTE interface of the TA+POC.
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 TA+POC.
Set up the parameter of the TA+POC 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 TA+POC 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.
To enter the AT command mode during an active data connection you must use the
following sequence ("Escape sequence"):
at least 1 sec pause <+><+><+> 1 sec pause
The time gap between all three plus signs may not exceed 1 sec.
The escape sequence is transmitted transparent to the remote device.

Automatic call establishment is available in the following modes:
• An automatic call will be initiated when control line DTR is on and transmit any
data character.
• 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 will be set
automatically to 9600 bit/s (br=4).
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.

3.5.2 Security callback (option)
With the security callback function you can initiate the called TA+POC to make an
automatic call to a predefined ISDN number.
The callback has to be enabled or disabled by using the command
"cmds2=40" Security callback enabled
"cmds2=0" Security callback disabled
If security callback is enabled and the calling number of an incoming calls fit's to one
entry of the acctab the called TA+POC will automatically try to establish a
connection using the entry in the casnr.
The incoming call will not be accepted and cause no RING message, the incoming
call will immediately and automatically rejected.
The automatic callback will be started after a delay as defined by the parameter
capa.
Only one automatic callback will be initiated by TA+POC.
There is no restriction in using the different command modes for the TA+POC that
has security callback enabled (i.e. AT dialing or automatic call DTR).
3.5.3 ISDN leased line (option)
To use the TA+POC with a leased line you have to setup the ISDN protocol to one
of the following values:
isdn=12
isdn=13
isdn=14
leased line with usage of just B channel B1
leased line with usage of just B channel B2
leased line with usage of both B channels.
With setting the ISDN protocol to leased line, no D channel protocol is used. A
connection will be established by dialing any number, if the activation of the leased
line access is available (LED1 is ON).
Note: to achieve data communication you should use one of the protocols async
HDLC or HDLC transparent.

3.6 B channel connections with external IOM use (option)
You can use the TA+POC with external devices connected to the B channel instead
of using the on board existing B channel hardware.
The B channel data have to be interfaced through the IOM interface.
The local devices are disabled by using the B channel protocol "prot=40" (external).
A connection can be setup by using the standard call control command sets like
ATD-command, automatic… (see setting of cmds).
For enhanced control of the B channel connections (i.e. voice connections, hold line,
…) the corresponding command set is described in the manual TA+HIT, section
external IOM interfacing.
3.7 User to User Signaling UUS1
With outgoing and incoming calls the transmission of User-to-User-Data (UUS1data) can be performed using the ISDN supplementary service UUS1. The UUS1data are transmitted transparently from the calling party to the called party before
the B channel connection is fully established.
Please note, that this ISDN service typically has to be enabled by the ISDN service
provider and may be charged additionally.
See the command ATD in AT command set:
Example:
ATDisdnnumber[//<UUS1-data>]
(PAD:)
X25number[I<ISDNnumber>[//<UUS1data>]]
“//”: separator for UUS1-data
The UUS1-data have a maximum length of 128 Bytes and will be interpreted as
ASCII characters.
Incoming UUS1-data are presented as enhancement to the RING and CONNECT
message.
AT:
RING [<rn>] [//<UUS1-data>]
CONNECT [<rn>] [//<UUS1-data>]
PAD: <X.25addr>I<isdnnumber>[//<UUS1-data>]

Examples:
ATD1234567890//userdata#010203*end
RING //userdata
RING //#01020304
3.8 Subaddressing
With outgoing and incoming calls the transmission of subaddresses can be
performed using the ISDN supplementary service SUB. The subaddress is
transmitted transparently from the calling party to the called party before the B
channel connection is fully established.
Please note, that this ISDN service typically has to be enabled by the ISDN service
provider and may be charged additionally.
The subaddress is separated by an “/“ from the called number.
The functionality Subaddressing can be used with the dialing procedures ATcommand set, PAD X.3 and automatic call.
Examples:
ATDisdnnumber[/subaddr]

3.9 X.25 address translation table
If the protocol X.25 B channel (prot = 20) is selected, then with every outgoing X.25
call the ISDN number will be taken out of the corresponding entry in the table xtab.
If no entry is found the X.25 address will be used as the ISDN number.
When an ISDN number is setup in the dialing command string with AT commands or
PAD X.3 commands, the xtab entries will not be used.
If an ISDN number is setup using the command dad, the table xtab will not be used.

xadr: To find an entry, the x25addr is compared against all
entries of xadr. The xadr can contain wildcards:
*:
represents one or more digits
?:
represents exactly one digit
nn/ss: the used ISDNnumber contains the number plus
subaddress, the subaddress can be empty.
nn = ISDN number, ss = subaddress
The ISDNnumber nn can contain following wildcards:
?:
represents exactly one digit, only allowed at the
end of the number. The value is taken from the
corresponding digits of the xadr.

3.10 X.25 D channel rerouting
If the protocol X.25 D channel (prot = 21) is selected an automatic establishment of
a B channel connection can be selected, if the X.25 call using the X.31-D channel is
not successful.
The B channel connection will be started if
• no successful X.25 connection is established within of a timeout set by command
"cato" in seconds
• an error is reported from X.31 D channel line.
The rerouting will be activated by setting the configuration command "x31rr=1" (from
PAD enter please "exec x31rr=1").
The ISDN number used for establishment of the B channel connection will be taken
from the table xtab dependent of the entry found in the table.
If the X.25 address meets no entry, the rerouting will not be used.
Example:
1. To enable rerouting for all X25 addresses:
x31rr 1
xtab1 *i04089928392
2. To enable rerouting for the x25 address 45400012345 and 45400012389:

3.11 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..
3.11.1 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.
3.11.2 Call Bumping
40
© Stollmann Entwicklungs- und Vertriebs-GmbH
2.19/07.2001
TA+POC manual
3. Using the TA+POC
A ML-PPP connection uses both B-channels of the S bus. To accept an incoming
call (i.e. for telephony) during a ML-PPP session one B-channel has to be released.
This is called Call Bumping.
To enable Call Bumping proceed as follows:
• Activate call waiting on the S bus. It has to be activated in the ISDN switch and is
a feature of the ISDN line you ordered.
• Open the “properties” of the dial-up link you are using for ML-PPP and “additional
settings”. Input “at**cmlp=1” as an additional parameter.
If there is an incoming call during a ML-PPP session the TA will drop one B-channel
and an ISDN telephone attached to the S bus will be ringing to accept the call.
The setting of cmlp is not affected by command AT&F.
Note: Due to the behavior of some public and private switching system call bumping
may not be supported.
3.11.3 Bandwidth on demand ("BOD")
Enabling this feature will cause the TA+POC 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.

The settings of the TA+POC for the serial interface and the S bus interface are
called configuration. The TA+POC 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 TA+POC 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 TA+POC 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 43).
• 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).
4.1 Configuring the TA+POC with AT commands
To execute one TA+configuration command cmd out of the AT command mode you

4.4.1 Remote access control
Using the following commands you can setup a table, to allow only dedicated callers
to get a connection to the remote management facilities inside the TA.
If this list is empty (default) or one entry with a star (*) is set, any incoming call is
allowed.
Every incoming call that does not fit to one of the entries of acctab will be rejected
with the ISDN cause „call rejected“.

4.6 Software update
The TA+POC 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
or via an remote configuration connection. Please fulfill the following steps to update
the TA+POC:
•
•
•
•
•
•
•
•
•
•
•
Get a new software release for the TA+POC from your supplier or
http://www.stollmann.de/ or ftp://ftp.stollmann.de/ and copy it to your PC.
Start a terminal emulation on your PC with the capability to run an X-MODEM file
transfer (i.e. HyperTerminal).
Remote update: establish a remote configuration connection (see page 43).
Local update: enter the TA+Configurator.
Enter the TA+Configurator command “fwload“.
Wait for end of erasing the Flash-EPROM and the prompt to start your XMODEM transfer.
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.
After completion you will get the information whether the software update ended
successfully or erroneous.
Activate the loaded new firmware with the configuration command “fwstart“.
Give the TA+POC about 20 seconds to activate the new software.
Due to new functionality the last stored configuration setting may be lost, please
check before using.
For more details refer to the description of the commands fwload and fwstart in the
chapter ”List of TA+Configurator commands” on page 46.
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 L1, L2, B1, B2 (Bootloader active). To store
a new firmware correctly you have to enter the command at**flash and load a
firmware using the XMODEM protocol as described above. This Bootloader
supports only AT**cmd with fixed baudrate of 115.200 Baud.

5. Diagnostic and error messages
5 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 84.
5.1 Error messages from AT command set
When the extended result messages are selected using the command ATW1 ISDN
error codes are displayed in addition to the standard AT result messages.
ISDN error causes from the ISDN network are always coded as 34xxH, whereas the
last two digits xx represent the ISDN cause in hexadecimal coding. The meaning
can be taken from the following tables ISDN causes (see page 68).
5.2 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.

5.6 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 01 00 02 05 00):
par := bl1 bl2 bl3 dl1 dl2 dl3 sl1 app
bl1
reserved
bl2
B channel frames: default 00
bit1: HDLC frames
bl3
reserved
dl1
D channel layer 1 status default 01
bit0: status
bit1: C/I codes after change
dl2
D channel LAPD frames: default 00
bit1: HDLC frames
dl3
D channel layer 3 messages: default: 02
bit1: Messages
sl1

Data bytes; continued lines are indicated by an “>“.
Coding of trace data bytes dependent of TypeAndSource:
The high order bit shows always the direction of the data:
0xxx = received data into the TA (from ISDN or serial)
8xxx = transmitted data by the TA (to ISDN or serial)

5.7 Call logging
Within the trace module functionality the logging of ISDN connection attempts –
successful or not – can be selected (default).
The buffer is build as a wrap around buffer, if full the oldest entries will be deleted.
The maximum number of entries is about 80.
Every entry is formatted in the following way:
EntryNo, int(TypeandSource), Date, Time, int(Appl), int(Service), Duration,
int(State), Cause, ChargingInfo, ISDN-No.
For detailed information about the Disconnect cause refer to chapter ISDN causes.
All not highlighted information are for internal use only.
The following commands can be used:
trcmsk 00000000 00000080.
