1.1 Product description
The TA+POX is an ISDN terminal adapter with the following functions. You can see
it as a digital replacement for an analogue modem.
• The TA+POX 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+POX by using
- asynchronous PAD (X.3) commands
- asynchronous AT commands
- automatic call
To work with TA+POX 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+POX

3. Using the TA+POX
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+POX to ISDN interface
Connect the PC's com-port to the DTE interface of the TA+POX.
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+POX.
Set up the parameter of the TA+POX 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+POX 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.

TA+HIX, TA+HUX, TA+POX, TA+SOC User manual
3. Using the TA+POX
r01/06.2009
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.

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).

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..
3.6.1 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.

Enabling this feature will cause the TA+POX 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.

3.7 ext. IOM-2 interface (option)
The following chapter will describe the ext. IOM-2 interface of the TA+HUX and
TA+SOC module. This option is not available in the external product TA+POX.
The call control commands describe within this document support the following
supplementary services for ISDN connections:
- CLIP
- MSN
- Overlap dialling
- Call waiting
- Call hold
- Call retrieve
- 3 party conference
3.7.1 ext. IOM-2 interface command set
The following section describes the enhancements for driving B channel connections
without switching the B channel to an on board device (Codec). The B channel data
have to be interfaced through the IOM interface.
To select the IOM2 interface of the TA+HUX or TA+SOC module you have to select
the correct B-channel protocol.
ATB40
external IOM2 audio connections (speech, S01 used, see
command CR…)
ATB43
external IOM2 data connections (speech, S02 used, see
command CR…)
ATB45
external IOM2 audio / data connections (Service user defined)
Every command is always answered by the ISDN-module; a following command
may only be entered after a response has been received.
Every AT command that controlles a B channel connection without switching an on
board device to the B channel is preceeded by a ":" and a dummy port number
(always "$").
Example: "AT:$ CR D1234"
; Establish a connection.
Result messages to the commands are preceeded by ":$"
Example: ":$CONNECT..."

Every B channel connection is identified by a call reference "Call-Reference".
The call reference is created and reported by the ISDN module:
- incoming call: as parameter to the "RING" message
- outgoing call: as result to the "CR" command.
The call reference has to be released by the application:
- with the command "DISC" or "REL".
All commands based on the same connection have to use the same call reference.
More than one call reference can be active at a time.
The B channel information is reported from the TA within the parameter Bxx.
The ATS7 register (Wait time for Carrier) is not supported for IOM-2 interface
connections.
The supported commands are described as followed:
Supported commands:
ATS80
Set pause between RING messages
ATS80?
Show actual values (decimal) of selected register nn
ATS80=xxx Set pause between displayed RING messages:
0: RING message not repeated,
D channel message ALERT not sent automatically
1..255: pause to repeated RING messages in 100ms steps.
D channel message ALERT sent automatically.
Default: 50 = 5 seconds.
Note: overlap receiving not possible.
ATS80?
Show current values (decimal) of register S80.
AT:$ A I<Call-Reference>
Accept incoming call
Using this command you can accept an incoming call, if automatic call acceptance is
not set (Register "ATS0" = 0). An incoming call is indicated by the result message
"RING" include the callreference value and the selected B-channel. See also the
chapter " AT result messages" in this document.
The Call-Reference is valid from the indication of an incomig call or the status
change of an connect request til the given release command.

following section it will be shown how, by using the configuration commands, you
can examine the configuration of the TA+POX 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+POX 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 64).
• 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).

4.4 Remote Configuration using the TA+Configurator commands
The TA+POX to be configured is referred here as “remote TA+POX”.
The TA+POX to configure is referred as “local TA+POX”.
Please make sure that the remote TA+POX to be configured at the other end is
connected to the ISDN line and powered up.

Connect the local TA+POX to ISDN interface
Connect the PC's com-port to the DTE interface of the local TA+POX.
Connect the power supply to the mains socket.
Start a terminal emulation program (i.e. Windows-Terminal)
Configure the local TA+POX with the B channel protocol X.75 and blocksize
2048 (ATB10).
Set up an ISDN connection to the remote TA+POX to be configured by using
the command: ATD<ISDN-No>e<↵>. The extension "e" at the end of the
calling number gives a connection to the internal remote access of the remote
TA+POX.
The called TA+POX TA+Configurator acknowledges by requesting the remote
password. Please enter the correct password (default: no password, just
return). Now you can work with the TA+Configurator by using the
TA+Configurator commands (see page 61).
Configure the parameter for the remote TA+POX from your terminal program
and store them (if wanted). (see page 66).
Example:
To change the used B channel protocol to X.75 please enter the
following commands:
prot 10<↵> (set protocol to X.75 - blocksize 2048)
save<↵>
(save the new configuration)
Hint: The active set of parameters can be displayed on screen by the
TA+Configurator with the command "show<↵>".
If necessary the remote TA+POX can be reset using the command
"reset<↵>".
Hang up the ISDN connection by leaving the TA+Configurator using the
command quit.
Leave your terminal program. After the next reset the changes will be active.
Now the configured remote TA+POX with the new set of parameters can be used by
running the needed PC program.

bch1delay
ISDN B-channel loop delay
(ATS31=1 needed)
This parameter set the data loop delay in the ISDN B-channel when S-register
S31=1 which activates the B-channel loop for incoming calls. The used B-channel
for the loop is given from the public switch within the incoming call message (DSS1:
SETUP, I-element: Channel Identification 0x18).
bch1delay ISDN B-channel data loop delay (in 64 byte steps)
bch1delay = {256 … 3968}, default: 256 Byte
The delay time in the B-channel can be controlled by changing the buffer size of the
internal memory in 64 byte steps (equals 8ms steps).
The minimum buffer size can be set to 256 byte.
The maximum value is 3968 byte.
The step size is 64 byte which equals 8ms.
Example:
t = 200 ms (delay time)
(must be divisible by eight)

reset
reset TA+POX
Resets the whole functionality of the TA+POX by a forced hardware reset (like
Power off / on). Refer also to parameter rsttim.
Note: If you reset a TA from remote management the "resetted" TA will loose it's
connection to the ISDN network. Due to timeouts of the ISDN network it can
take up to 30 seconds till the local TA will notify the released connection.

(independent of br or recognized local baudrate)
brn = 0 :
"adaptive": same mechanism as brn # 0; the V.110 baudrate will
be created by br rsp. the recognized local baudrate.
- Incoming call:
brn # 0 :
no LLC received: accept incoming call, use in B channel brn for
V.110 baudrate.
LLC received compliant to brn: accept incoming call
LLC received not equal to brn: Reject incoming call:
DISCONNECT (cause = incompatible destination).
brn = 0 :
"adaptive":
no LLC received: accept incoming call, use in B channel br rsp.
the recognized local baudrate for V.110 baudrate.
LLC received: accept incoming call, use in B channel the
baudrate derived from the LLC as V.110 baudrate.
The usage of the LLC is controlled by the TA+Configurator command

4.6 Software update
The TA+POX 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 TA+POX:
•
•
•
•
•
•
•
•
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 TA+POX 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.

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 107.
5.1 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 91). All other causes are CAPI error causes (see
page 99).
Error cause display:
<xx> = ISDN release (error) cause, hexadecimal
Example:
Tx data
ATW1
Rx data
OK
ATD12345
NO CARRIER <34A2>
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:

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 77 00 72 05 02):

8xxx : outgoing event (to ISDN line)
“FFFF“ : Reset for firmware
Length of following data bytes
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)
