Introduction
We are very pleased to see that you have bought a INSYS product and would like
to express our appreciation.
This documentation is valid for the product:
•
POCKET ISDN-TA hardware version V2.0 or higher
Software version V5.351 or higher
1.1
Product description
•
The POCKET ISDN-TA connects a PC (or other device with serial port)
to the ISDN. It gives access to online services as the Internet,
AOL/CompuServe and T-Online and is also suitable for remote LAN
access. You can see it as a digital replacement for an analogue
modem.
To work with POCKET ISDN-TA 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 online software for a modem (see chapter 3)
The serial port of the PC should be capable of a data rate of up to 115.2 kbps
(230.4 kbps for Multilink PPP to increase performance). This might require an
additional PC card for older PCs.
1.2
Internet Access
There are three ways to access the Internet via ISDN:
•
by synchronous PPP or Multilink PPP
•
by bit rate adaptation V.120
•
by B channel protocol X.75
It depends on the access facilities of your Internet service provider (ISP) or
Point-of-presence (POP) which one you may use (see figure 1).

AOL/CompuServe Access
AOL/CompuServe is accessed via ISDN by the protocol V.120 or X.75 (see picture
1). It depends on the access facilities of your AOL/CompuServe access point
which one you have to use (see figure 1). The increasingly common protocol used
is X.75.
1.4
T-Online
T-Online (German Online Service) is accessed via ISDN by the protocol T.70NL /
X.75 or synchronous PPP (see figure 1).
1.5
Remote LAN Access
To access a LAN remotely via ISDN you have to choose the appropriate protocol
that is used by the ISDN router on the LAN.
1.6
Service
INSYS has installed a Windows-NT-Server just for test purposes. The Server supports
the RAS (Remote Access Service) with full 64 kbps in one single B channel. The RAS
service gives the possibility to connect PC's using Windows-2000/NT or
Windows9x/ME with each other.
You have to install on your Windows PC the Dialup Networking – see the Windows
helpdesk how to install and use. Please select at your machine the protocol stack
TCP/IP.
The POCKET ISDN-TA has to be set to HDLC async to sync (like the configuration for
Internet access) by selecting the Modem “TA Internet PPP”.

Operating manual Pocket ISDN-TA
Using the POCKET ISDN-TA with Application Software
To use the POCKET ISDN-TA with different application software and access points
you have to look for the following items:
•
Usually you need a contract with the service provider. They can help
you to get an appropriate application program to run on a PC.
•
The service provider will also supply you with the ISDN access number
to call (has to be entered in the application program).
•
The TAs parameter must fit the characteristics of the access point
which be recommended in the next chapters.
3.1
Configuration for Internet
To access the Internet via ISDN you have to have a contract with an Internet
service provider (ISP) who runs an ISDN access. To configure the POCKET ISDN-TA
you need the following information from the ISP:
•
ISDN access number (to be entered at the PC program)
•
Layer two protocol, usually the protocol PPP by selecting Modem
POCKET ISDN-TA Internet PPP.
•
Access protocol (to be entered at the PC system software or Internet
software)
To configure the Internet access software on the PC it may be necessary that you
need some additional information like TCP/IP address, user name, password etc.
Please refer to the software manual.
3.1.1 Configuration under Windows 9x/ME/2000
The configuration of the POCKET ISDN-TA can be dependent of the type of access
the Internet provider is supporting. The following types of access are mostly used
for public ISDN access.
• HDLC async to sync conversion
This protocol has to be set up, if the service provider uses an access point
where the protocol PPP is running.
Please get more information from your Internet provider if necessary.

Configuration for AOL/CompuServe
You need a contract with AOL/CompuServe to access the AOL/CompuServe
network via ISDN. To configure the POCKET ISDN-TA you need the following
information from AOL/CompuServe:
•
ISDN access number
•
Layer two protocol, usually the protocol-type X.75 by selecting
Modem POCKET ISDN-TA X.75. Some accesses still use B channel
protocol V.120 (select Modem TA V.120).
How to select the modem see also page 4.
You can use a CompuServe access by running the CIM software package. For
AOL use the AOL software.
3.3
Configuration for T-Online (Germany only)
To use the T-Online service via ISDN you have to have a contract for a T-Online
access. For configuration you have to set up the following parameter:
•
ISDN access number, "01910" for a basic rate access.
•
The protocol T.70 by selecting Modem TA T-Online.
•
Select the appropriate access type in your T-Online access software
(COM port)
Alternatively since summer 1997 another access point for T-Online has been
created (the latest T-Online software package has to be used):
•
ISDN access number, "0191011" for a basic rate access.
•
The protocol PPP by selecting Modem TA HDLC-PPP.

Operating manual Pocket ISDN-TA
Configuring the POCKET ISDN-TA
The settings of the POCKET ISDN-TA for the V.24 interface and the S0 interface are
called configuration. The POCKET ISDN-TA 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 POCKET ISDN-TA 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 POCKET ISDN-TA in the following ways:
• by using the AT command set entered by the locally connected PC.
• by using TA configuration commands entered by the locally connected PC.
• by using TA configuration commands entered via the ISDN line (remote
configuration).
Normally the configuration via AT commands is sufficient.
The latter case are for more sophisticated configuration and described in the
chapter TA+Configurator command set
4.1
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 POCKET ISDN-TA to ISDN interface
Connect the PC s com-port to the DTE interface of the POCKET ISDN-TA.
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 POCKET ISDN-TA.
Set up the parameter of the POCKET ISDN-TA 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
Configuring the POCKET ISDN-TA
11
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. The
command line is automatically cancelled by longer input. Blanks are ignored,
capital/small letters are not significant.
The parameter settings of the POCKET ISDN-TA 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.
Supported commands:

In AT command mode, call number display (does not belong to the AT command
standard) can be turned on by issuing the command ATV2 or ATV3. If turned on,
the call number of the caller is shown with the Connect- or Ring-message (in
pointed brackets), depending on the signaling in D-channel.
If the POCKET ISDN-TA is used at the public network then the call number of the
remote site (including area code) is displayed.
Example:

the acctab.
4.3 User to User Signalling 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 enhencement to the RING and CONNECT
message.
AT:
RING [<rn>] [//<UUS1-data>]
CONNECT [<rn>] [//<UUS1-data>]
PAD: <X.25addr>I<isdnnumber>[//<UUS1-data>]
COM
Note: The presentation of UUS1-data has to be enabled by command ATW1.
26
Operating manual Pocket ISDN-TA
The data are presented as ASCII characters.
An incoming call can be accepted (S0 register set to 0) by an ATA or rejected by
an ATH combined with the transmission of UUS1-data (AT only):
ATA [//<UUS1-data>]
ATH [//<UUS1-data>]
Examples:
ATD1234567890//userdata#010203*ende
RING //userdata
RING //#01020304
4.4 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 dialling procedures ATcommand set, PAD X.3 and automatic call.
Examples:
ATDisdnnumber[/subaddr]
isdnnumber
Dialling called party number
subaddr
Called subaddress
RING [<rn>[/subaddr]]
CONNECT [<rn>[/subaddr]]
rn
subaddr
Calling party number

The own subaddress (calling subbaddress) can be setup using the configuration
command sub.
Note: The subaddress can be entered additionally into all tables that contain ISDN
numbers for dialling or checking an ISDN address.
4.5
Using Multilink PPP
Configuring the POCKET ISDN-TA
27
To enable Multilink PPP handling within the POCKET ISDN-TA please enable the B
channel protocol ML-PPP: atb31 rsp. prot = 31.
ML-PPP may be used with different authentification procedures during the call up
of the line. One of these is CHAP. You may enable ML-PPP CHAP by the following
steps:
• Enter “at**chappwd=<password>” to input your password in the POCKET
ISDN-TA.
• Enter “AT&W” to store the setting in the POCKET ISDN-TA.
Afterwards a ML-PPP connection is initially made using CHAP authentification. If
the server does not handle CHAP an automatic fallback to PAP is performed.
You may control the settings by typing “AT&V1”.
Warning: Since the password is shown in plain text it may be disclosed by
unauthorized persons.
4.5.1 Details on Multilink PPP
Currently on INSYS TAs running Multilink PPP (ML-PPP) the following authentication
protocols (AP) are supported:
•
•
•
•
Password Authentication Protocol (PAP)
Challenge Handshake Authentication Protocol (CHAP) with the variants
MD5 according to RFC 1321
Microsoft Chap according to RFC 2433
PAP exchanges the password in clear text format in the B-channel, whereas CHAP
encrypts the password according to the algorithms described in the RFCs
mentioned above. For CHAP the password has to be stored in the POCKET ISDN-TA
in addition to the setting in the Dial-up Network under Windows 95. Under Windows
98/ME/2000 this is not necessary.
The following basic rules apply when the POCKET ISDN-TA is configured to run MLPPP:
1. If the remote side requests (in the Link Control Protocol LCP ConfigRequest) an
AP that the POCKET ISDN-TA can handle, the request is forwarded to local side.
2. If the remote side requests an AP that the POCKET ISDN-TA cannot handle, the
POCKET ISDN-TA proposes the safest protocol depending on its capabilities:
• PAP if no password chappwd is locally stored,
• CHAP/MS-CHAP MD5 if a password chappwd is locally stored.
This step may be repeated a limited number of times only, if this number
exceeds, the POCKET ISDN-TA falls back to single link operation until the next
connection is tried.
28
Operating manual Pocket ISDN-TA
3. Once the local side rejects (with a LCP ConfigNak) an AP that was alternatively
proposed by the POCKET ISDN-TA (see previous rule), the POCKET ISDN-TA falls
back to single link operation until the next connection is tried. Local and remote
side may negotiate any AP they like.
4. At the end of the link setup procedure the negotiated AP is checked and, if
supported, is used for the second link too. If the final AP is not supported the
second link is not established, the POCKET ISDN-TA falls back to single link
operation until the next connection is tried.
Note that some hosts are very strict, e.g. if PAP is proposed by the POCKET ISDN-TA
due to the lack of a locally stored password chappwd they simply hang up the
connection without any chance to negotiate anything else. In these cases the
POCKET ISDN-TA should be configured for single link PPP operation, or,
alternatively, the chappwd should be supplied and stored on the POCKET ISDN-TA.
4.5.2 Call Bumping
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 POCKET ISDN-TA will drop
one B-channel and an ISDN telephone attached to the S bus will be ringing to
accept the call.
4.5.3 Bandwidth on demand ("BOD")
Enabling this feature will cause the TA+PP2 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 for data
transfer used.
• if the throughput of the internet connection is lower than a definable value the
second B channel connection will be disconnected automatically.

Software update
The POCKET ISDN-TA uses a Flash-EPROM to store the software. This software can be
updated from a local connected PC via the COM port.
4.6.1 Software update
Please fulfil the following steps to update the POCKET ISDN-TA:
•
•
•
•
•
•
•
•
Get a new software release for the POCKET ISDN-TA from your supplier 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).
Enter the AT command “at**flash“.
Wait for end of erasing the Flash-EPROM and the prompt to start your X-MODEM
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.
Give the POCKET ISDN-TA about 20 seconds to activate the new software.
Due to new functionality the last stored configuration setting may be lost,
please check before using. To set factory default values please use the
command "at&f1".
