3General Information
The Pocket ISDN is available in two versions. These are
Pocket ISDN Profi
Pocket ISDN Internet
Both versions of the Pocket ISDN differ in the following characteristics:
Pocket ISDN Internet Profi
CAPI interface Yes No
Multilink PPP Yes No
Security callback No Yes
X.25 No Yes
X.31 in D channel: No Yes
Table 1: Differences between Pocket ISDN Profi and Internet
Both versions are referred to as Pocket ISDN in the further course of this manual. If the
Pocket ISDN Profi differs from the Pocket ISDN Internet, this will be mentioned explicitly
in the respective sections.
Please note that you cannot use an ISDN device for digital data communi-
cation to establish a connection to an analogue modem.
3.1 Product Description
The Pocket ISDN connects a PC (or other device with a serial interface) to the ISDN net-
work. It provides access to online services like Internet, AOL/CompuServe and T-Online.
Moreover, point-to-point connections between two ISDN data terminal devices or a con-
nection to a GSM modem can be established. The Pocket ISDN can be considered as digi-
tal replacement for an analogue modem.
In order to operate the TA, you will need:
an ISDN basic rate interface (BRI) (replaces the analogue telephone connection). The
basic rate interface can be ordered with the telephone service provider.
a PC with serial RS232 interface (RS232)
The serial interface of the PC should be suitable for data rates of up to 115.2 kbps. It
might be possible that older PCs require an additional PC card for this.
It is possible to increase the data rates over the ISDN line to 230.4 kbps using Multilink
PPP with the Pocket ISDN Internet.

Pocket ISDN General Information

3.2 Internet Access
There are three methods for Internet access via ISDN:
with synchronous PPP or Multilink PPP (only with Pocket ISDN Internet)
with bit rate adaption V.120
with the B channel protocol X.75
It depends on the access devices of your Internet service provider (ISP) or point-of-
presence (POP), which protocol you can use.
Figure 1: Connection of the Pocket ISDN for access to an online service
3.3 AOL/CompuServe Access
The access to AOL/CompuServe via ISDN takes place using the V.120 or X.75 protocol (re-
fer to Figure 1). The protocol depends on the access devices of your AOL/CompuServe
dial-in node. The most frequently used common protocol is X.75.
3.4 T-Online
The T-Online (German online service) access via ISDN takes place using the T.70NL / X.75
or the synchronous PPP protocol (refer to Figure 1).
3.5 LAN Remote Access
You have to select the respective protocol of the ISDN router at the LAN for a remote ac-
cess to a LAN network.

Pocket ISDN Function Overview
19
6Function Overview
The Pocket ISDN provides you with the following functions:
Operation at ISDN point-to-point and multipoint interface
The Pocket ISDN can be operated at ISDN point-to-point interfaces as well
as at multipoint interfaces.
Different transfer protocols
The Pocket ISDN supports different transfer protocols, like e.g. X.75, V.110
and HDLC (for PPP connections).
Data buffering for serial transmission
The Pocket ISDN provides send and receive buffers to adjust the Pocket
ISDN to the data processing speed of the application.
Hardware and software data flow control
The Pocket ISDN can interrupt the data flow of the application via the con-
trol lines of the serial interface, if the buffers of the Pocket ISDN exceed a
certain level. An application can also prompt the Pocket ISDN via a control
line to interrupt the data flow. As an alternative, the Pocket ISDN can con-
trol the data flow via XOFF/XON characters in the data stream.
Selective Call Acceptance
The Pocket ISDN can be set to accept only calls from phone numbers that
were previously stored.
Security Callback (only Pocket ISDN Profi)
The called Pocket ISDN can initiate an automatic call to a predefined num-
ber, if a specified caller could be identified using CLIP.
Automatic call
The Pocket ISDN can initiate an automatic call either depending on the
DTR signal or independent of a status line.
Remote configuration
The Pocket ISDN can be configured remotely using another INSYS ISDN de-
vice and a terminal program.
