1 Introduction to the AVM ISDN-
Controller T1/T1-B
1.1 The ISDN Network
ISDN, the Integrated Services Digital Network, has
been available in Germany since 1989, and is consid-
ered the universal telecommunications network of the
future.
Among ISDN’s characteristics are:
- High speed
The B channels, which are used to transmit user data,
have a throughput of 64 Kbit/s. The two B channels of
an ISDN basic-rate (S
0
) interface can be bundled to
obtain a maximum throughput of 128 Kbit/s. The
primary rate (S
2M
) interface, with 30 B channels, allows
a total throughput of about 2 Mbit/s.
- Digital transmission
In contrast to analog data communications, line inter-
ference and data errors are practically eliminated. This
makes data communications in ISDN not only faster,
but also more reliable than in analog networks.
- Fast dial-up connections
Call setup in ISDN takes only 1 to 2 seconds.
- Integration of services
Integrated services means that voice, data and images
can all be transmitted over a single network. Users only
need one line for all kinds of communications applica-
tions.

1 Introduction to the AVM ISDN-Controller T1/T1-B
1.1.1 ISDN Line Types
There are two standardized types of access to ISDN:
- ISDN BRI (S
0
interface) with 2 B channels
(64 Kbit/s each) and one D channel (16 Kbit/s)
- ISDN PRI (S
2M
interface) with 30 B channels
(64 Kbit/s each) and one D channel (64 Kbit/s)
Control functions for communication between the user
and the network are handled over the D channel using
the same protocols for the S
0
and S
2M
interfaces. The D
channel protocol for lines provided by Deutsche Telekom
AG may be 1TR6 (national ISDN) or DSS1 (Euro-ISDN).
The D-channel signaling is the only difference between
national ISDN and Euro-ISDN. The hardware for all PRI
lines is the same, so that no hardware modifications are
necessary when changing from 1TR6 to DSS1. The
AVM ISDN-Controller T1/T1-B’s software supports
both D-channel protocols.
1.1.2 The Primary Rate Interface
The primary rate interface provides 30 user data
channels (B channels) and one signalling channel (D
channel). The data rate over each of these channels is
64 Kbit/s. In contrast to the BRI with just two B
channels, the PRI’s channels can be individually config-
ured for specific purposes: for incoming connections
only, for outgoing connections only, or for both incom-
ing and outgoing connections.
The actual data transmission takes place using a time-
multiplex technique. The data from each channel is
switched onto the physical line successively in a fixed
cycle. Each time frame is 125 µs in duration, and 256
bits are sent in this time. These 256 bits are composed
of 8 bits from each B and D channel plus 8 synchroni-
zation bits (30 B channels * 8 bits + 1 D channel * 8 bits
+ 8 synchronization bits = 256 bits).

1 Introduction to the AVM ISDN-Controller T1/T1-B
The ISDN network ends at the subscriber’s premises in
the network terminator (NT). This device provides the
subscriber with the S
2M
interface. The abbreviation S
2M
refers to the total throughput at this interface, which is
about 2 Mbit/s. The network operator may carry the
signal over certain four-conductor paired copper cables
(120W impedance), over coaxial cable (75W imped-
ance), or over fiber optic lines. Depending on the
medium used, the NT’s network-side interface to the
local switching station is designated as the U
K2
(copper)
or U
G2
(fiber optic) interface. Accordingly, the NT
installed by Deutsche Telekom AG is either an NTPMKU
(U
K2
), an NTPMGF (U
G2
) or an NTMP.
The AVM ISDN-Controller T1/T1-B is connected to
the NT’s S
2M
interface by a four-lead shielded twisted
pair cable. The NT must be supplied with electrical
power, either through a separate power supply or
through an adapter. The power supply or adapter must
be installed by the network operator.
1.2 The AVM ISDN-Controller T1/T1-B
The AVM ISDN-Controller T1/T1-B is a complete
ISDN system solution for the primary rate (S
2M
) inter-
face. It supports all 30 B channels of the S
2M
line
simultaneously. Its high capacity makes the AVM ISDN-
Controller T1/T1-B especially suited to server appli-
cations.
The Controller is constructed as a 19" unit and can be
installed either free-standing or in a 19" equipment
rack.
The hardware architecture of the T1, based on a
network of CPUs, is a superior engineering solution
with a high degree of flexibility and scalability. The
difference in the AVM ISDN-Controller T1-B as
compared with the AVM ISDN-Controller T1 consists
in the incorporation of additional hardware for in-
creased performance capabilities: the AVM ISDN-
10
1 Introduction to the AVM ISDN-Controller T1/T1-B
Controller T1-B has a second processor board, for a
total of 7 CPUs and 17 MB of RAM. Four CPUs are
available for additional internal tasks such as V.42bis
data compression on 30 simultaneous channels. The
AVM ISDN-Controller T1 has one processor board
with 3 CPUs and 9 MB of memory. The T1/T1-B is linked
to the PC by a high-speed serial link to a PC bus
interface card.
Fig The AVM ISDN-Controllers T1/T1-B installation
The driver and protocol software is downloaded from
the host PC on initialization. The software is oriented
after the ISO OSI protocol layer model, and covers
Layers 1 to 3 of both the data and signalling channels.
This loadable controller software concept permits flex-
ible adaptation to new requirements without installing
new hardware or firmware, and forms the basis for
flexible adaptation to a variety of purposes and network
configurations.
The AVM ISDN-Controller T1/T1-B is equipped with
driver software in conformance with the international
standard COMMON-ISDN-API Version 2.0 (CAPI 2.0).
This driver software supports the protocols X.75 trans-
parent, HDLC transparent, X.25, ISO 8208 (X.25 DTE-
DTE) and bit-transparent. As a special feature, the

protocols V.110, V.120 and ISO 3309 are also sup-
ported. The ISO 3309 protocol is used primarily in the
field of GSM cellular communications, as with Mobile
ISDN.
The AVM ISDN-Controller T1/T1-B conforms to the
ITU-T I.431 recommendation and supports all 30 B
channels and the D channel of the S
2M
interface at
64 Kbit/s. On the ISDN D channel, the T1-B supports
both the European DSS1 protocol and the national
protocol 1TR6. The controller has international approv-
als for use throughout Europe.
The driver software is available for the operating
platforms Novell NetWare, Windows NT and MS-DOS.
Several AVM ISDN-Controllers can be easily combined
in one PC. Up to four active AVM ISDN-Controllers can
be operated simultaneously.
Installation of the ISDN-Controller hardware and soft-
ware completely connects the PC to ISDN.

• An ISDN primary rate interface
• An ISDN NT (Network Terminator) including power
supply or separate power adapter, installed by your
ISDN provider
• A PC with a 486 or higher CPU and a free ISA or EISA
bus slot
Examine the contents of your AVM ISDN-Controller
T1/T1-B package (see Chapter 1). If any part is
missing, contact your dealer immediately.
The hardware installation entails the following steps:
1. Installing the PC interface card
2. Connecting the cable from the PC interface card to
the AVM ISDN-Controller T1/T1-B
3. Connecting the cable from the T1 to the NT
4. Connecting the T1 power supply
These steps are described in order below. The illustra-
tions are found in Appendix B, Illustrations.
14
2 Hardware Installation
2.1 Installing the PC Interface Card
The AVM ISDN-Controller T1/T1-B is connected to
the personal computer through a PC interface card.
The PC interface card is a 2/3-length plug-in adapter for
the ISA or EISA bus slot. For EISA bus architecture
support, the configuration file !AVM0004.CFG is in-
cluded on the DOS driver disk. Please consult your
computer’s manual for further information on installing
hardware components.
Make sure the I/O address 150 is not in use by any
other plug-in adapters in your computer. This is the
default I/O address used by the first PC interface card
you install.
In order to operate several AVM ISDN-Controller
T1/T1-Bs in one computer, you must first assign a
unique number to each PC interface card. Read how
to do this in Section 2.1.1.
Install the interface card as follows:
1. Make sure the PC and any connected peripherals
are turned off and their power cords discon-
nected.
2. Open the PC housing. Touch a bare metal part of
the chassis to discharge any static electricity from
your body.
3. Select an appropriate bus slot, remove the back
slot cover plate and insert the PC interface card in
the slot.
4. Screw the back plate of the PC interface card onto
the PC chassis.
5. Close the computer and plug in the power cord.
This completes the installation of the PC interface card.
15
2 Hardware Installation
2.1.1 Installing Several PC Interface Cards
In order to operate several AVM ISDN-Controller
T1/T1-Bs in one computer, you must first assign a
unique number to each PC interface card. This number
is required so that each card can be addressed and
initialized unambiguously. The number for the second
and each succeeding ISDN-Controller must be as-
signed by setting the DIP switches found on the PC
interface card (see illustration below.
The DIP switches are numbered from right to left:
Fig. Positions and significance of the DIP switches
The binary number of the card corresponds to the
positions of the DIP switches 1.1 to 1.4. The factory
setting is 0. The card number for any given combination
of switch settings is calculated as follows:
2
3
*SW1.4 + 2
2
*SW1.3 + 2*SW1.2 + SW1.1
where the ON position of each DIP switch has a value
of 1 and the OFF position a value of 0.
Before installing PC interface cards for additional ISDN-
Controllers, set each card to a number not yet used.
Then proceed to install each card as described above
under “Installing the PC Interface Card”.

2.2 Connecting the Cable from the PC
Interface Card to the AVM ISDN-
Controller T1/T1-B
After you have installed the PC interface card, it must
be connected to the AVM ISDN-Controller
T1/T1-B.
To prevent interference in the high-frequency link, no
extensions should be added to the cable supplied.
1. Connect the 15-pin sub-D connector of the cable
supplied to the upper socket on the back plate of
the PC interface card (see Fig. 1). Nothing needs
to be connected to the lower socket of the PC
interface card.
2. Connect the 9-pin sub-D connector of the cable to
the 9-pin socket on the ISDN-Controller T1/T1-B
(see Fig. 3).
3. Secure both connectors by tightening the finger
screws.
Now the AVM ISDN-Controller T1/T1-B must be
connected to the ISDN network terminator (NT).
2.3 Connecting the Cable from the ISDN-
Controller T1 to the NT
This section explains how to connect the cable from the
AVM ISDN-Controller T1/T1-B to the ISDN network
terminator (NT) installed by the ISDN provider.
The ISDN operator Deutsche Telekom AG uses various
types of NTs. For this reason, two different connection
procedures are described:
1. Connecting the ISDN-Controller T1 to the NTPM (NT
with terminal board)
17
2 Hardware Installation
2. Connecting the ISDN-Controller T1 to the NTPMKU
or NTPMGF (NTs with T-shaped mounting plate)
Examine your NT and determine which type it is. In case
of doubt, contact your ISDN operator’s technical ser-
vice.
When errors and malfunctions occur at the NT, the S
2M
interface may no longer synchronize with the local
switch. In this case the switch temporarily disables
the PRI. This is indicated by a red LED on the NT.
Newer local switches re-enable the interface again
automatically.
Such synchronization errors may occur during the
AVM ISDN-Controller T1/T1-B connection proce-
dure. If the line is not automatically re-enabled,
contact your ISDN operator’s technical service.
2.3.1 Connection to the NTPM (NT with Terminal
Board)
To ensure that the S
2M
interface remains synchro-
nized with the local switch when no terminal equip-
ment is connected, the is NT usually outfitted with wire
jumpers between terminals S2M ab/a and S2M ab/b,
and between terminals S2M an/a and S2M an/b (“an”
= in; “ab” = out). These jumpers must not be removed
until the terminal equipment—in this case, the AVM
ISDN-Controller T1/T1-B—is operational, i.e. its
driver software has been loaded.
1. Connect the 9-pin sub-D connector of the cable to
the 9-pin socket of the AVM ISDN-Controller
T1/T1-B (see Fig. 3 in Appendix B, Illustrations).
Secure the connection by tightening the finger
screws. Route the 6 meter cable as directly as
possible to the NT.
2. Unlock and remove the cover of the NTPM’s
connection terminals.
18
2 Hardware Installation
3. Remove the back covers of the inserts.
4. Screw the cable onto connector strip X2 on the
terminal board.
See Table 1 in Appendix C, Tables, for the pin
assignments to connect the AVM ISDN-Control-
ler T1/T1-B’s cable to the terminal strip.
5. Connect the cable leads to the correct terminals
on the terminal strip.
6. Replace the cover over the terminals and lock it.
2.3.2 Connection to the NTPMKU or NTPMGF
(NTs with T-shaped Mounting Element)
1. Connect the 9-pin sub-D connector of the cable to
the 9-pin socket of the AVM ISDN-Controller
T1/T1-B (see Fig. 3 in Appendix B, Illustrations).
Secure the connection by tightening the finger
screws. Route the 6 meter cable as directly as
possible to the NT.
2. Unlock and remove the cover of the NTPMKU or
NTPMGF connection terminals.
3. In the NT there is a T-shaped mounting element for
the connecting cable (see Fig. 4 in Appendix B,
Illustrations). Open it to affix the cable by undoing
the screws.
See Table 2 or Table 3, depending on your NT
type, in Appendix C, Tables, for the pin assign-
ments to connect the AVM ISDN-Controller T1/
T1-B’s cable leads to the NTPMKU or NTPMGF
terminals.

3 Driver Software Installation – MS-DOS
3 Driver Software Installation
Driver software for the AVM ISDN-Controller T1/T1-B
is available for the operating systems Windows NT, Novell
NetWare and MS-DOS. This chapter contains a section for
each of these platforms describing the installation of the
driver software, configuration of the ISDN-Controller, load-
ing and unloading of the driver software, installation of
additional controllers and removal of the ISDN-Controller
from the system.
Once installed and loaded, the driver provides the applica-
tion interface COMMON-ISDN-API (CAPI) Version 2.0 to the
entire system.
AVM ISDN-Controller driver software undergoes continu-
ous development, and updated drivers are available to you
free of charge. You may download the latest drivers for
your AVM ISDN-Controller T1/T1-B from the AVM Data
Call Center using Connect2 (included) or FRITZ!data. The
drivers are also found in the Internet on AVM’s FTP server.

Before you begin the software installation, find out what D-
channel protocol your ISDN line uses. In Germany, this may
be either the DSS1 (Euro-ISDN) or the 1TR6 protocol. ISDN
lines connected after December 1993 are generally DSS1
lines. The 1TR6 protocol is rarely used today.
3.1 MS-DOS Installation
Special drivers are supplied with the ISDN-Controller for
use in MS-DOS. Once installed, the driver provides the
application interface COMMON-ISDN-API (CAPI) Version
2.0 to all programs (see Appendix A).

MS-DOS
Before you begin the installation, make sure the PC
interface card(s) have been correctly installed in the
computer. Make sure too that the I/O address 150 is not
used by any other adapters in the PC. This is the default
value used by the first PC interface card installed. If you
want to operate several AVM ISDN-Controller T1s/
T1-Bs in one computer, you must first assign each PC
interface card a unique card number. See the instructions
in Chapter 2, “Hardware Installation”.
3.1.1 Installing the Driver Software
To install the driver software, proceed as follows:
1. Insert the original disk labeled “AVM ISDN-Controller
T1, Installation DOS” in your floppy disk drive.
2. Change the current directory to your floppy disk drive
and then enter
install <Return>
to start the installation program. The installation
program’s sign-on screen appears. You can abort the
installation at any time by selecting EXIT or by
pressing Ctrl+X. To proceed with the installation,
press Return.
3. Select the D-channel protocol used by your ISDN line
(DSS1 or 1TR6).
Use the Tab key to select the desired entry, then
confirm by pressing Return.
4. A list of available drives appears. Choose the drive on
which the driver software is to be installed.
Use the arrow keys to browse in the list and confirm
your choice by pressing Return.
5. Next, choose the subdirectory where you want to
install the controller software.
The default is \IDRIVER, but this can be changed to any
name you wish. Confirm again by pressing Return.

(“ibase”, space, minus sign) at the DOS prompt.
The “System” LED goes out.
3.1.3 Installing Additional ISDN-Controllers
To operate several AVM ISDN-Controller T1/T1-Bs in
one PC, you must edit the files T1INIT.BAT and
ISDNLOAD.CFG in the driver installation directory.
Begin by opening the file T1INIT.BAT in a text editor. Copy
and paste the two lines that begin with “@cta2.exe …” and
“@afserver …”, so that they now appear twice in the file.
The program CTA2.EXE initializes and configures one PC
interface card installed in the computer. It is started with
the following command line arguments:
/N#xx indicates the board number
T1INIT.BAT
23
3 Driver Software Installation – MS-DOS
/L#xxxx sets the interface card’s I/O address
/I#xx sets the interface card’s interrupt level (xx is a
hexadecimal number from 08 to 0F; see table)
Note: The value of the command line parameter “/I#” is
not itself the interrupt (IRQ) level! To determine the value
for this parameter that corresponds to the desired inter-
rupt level, refer to the following table:
Table Choosing a valid interrupt
The program AFSERVER.EXE runs a test routine on the
AVM ISDN-Controller T1/T1-B. Please note that the
first argument, “-:l”, is formed with a lower-case L, not with
the numeral 1!
Example:
@cta2.exe /N#01 /L#220 /I#0D /SP#05
@afserver -:l #220 -:b worm.b4
The first command sets the PC interface card with the
board number “01” to the I/O address “220” and the
interrupt 11. The second command tests the ISDN-Con-
troller that is set to the I/O address 220.
The argument “/SP#xx” sets the serial link speed. The
preset value, “05”, must not be changed.

Then open the file ISDNLOAD.CFG (likewise found in the
driver software installation directory) in a text editor. Copy
and paste the entire section beginning with “[ISDN-Control-
ler-00]”, so that the section appears twice in the file.
In the new copy of the section, increase the controller
number in the section header by 1 for each successive
ISDN-Controller, then enter the desired I/O address and
interrupt level for the additional PC interface card.
Example:
[ISDN-Controller-00]
IO-Adresse=150
Interrupt=5
[ISDN-Controller-01]
IO-Adresse=220
Interrupt=11
Once this has been done, the second controller will also be
initialized the next time IBASE.BAT is run.
3.1.4 Removing the Driver Software
To undo the installation of the AVM ISDN-Controller T1/
T1-B for MS-DOS, first remove the driver from memory by
entering the command ibase -.
Then use the appropriate DOS commands to delete the
driver software and the installation directory. If you have
added the command ibase to your AUTOEXEC.BAT file,
you must also remove it again.
3.2 Windows NT Installation
Installation and configuration of the AVM ISDN-Control-
ler T1/T1-B are almost identical for the Windows NT
versions 3.51 and 4.0.
Specially developed Windows NT driver software is sup-
plied with the AVM ISDN-Controller B1 PCI. The applica-
tions interface COMMON-ISDN-API Version 2.0 supplied
supports both 16-bit and 32-bit applications (applications
ISDNLOAD.CFG
25
3 Driver Software Installation – Windows NT
in DOS windows are not supported, however). See Appen-
dix A for further information about CAPI.
Before you begin the installation, make sure the PC
interface card(s) have been correctly installed in the
computer. Make sure too that the I/O address 150 is not
used by any other adapters in the PC. This is the default
value used by the first PC interface card installed. If you
want to operate several AVM ISDN-Controller T1s/
T1-Bs in one computer, you must first assign each PC
interface card a unique card number. See the instructions
in Chapter 2, “Hardware Installation”.
3.2.1 Installing the Driver Software
To install the driver software, proceed as follows:
1. Start Windows NT.
2. Insert the original disk labeled “AVM ISDN-Controller
T1, Installation Windows NT” in your floppy disk drive.
3. Select the “Run” command in the Windows NT 4.0
Start menu (Windows NT 3.51: select the “Run”
command in the “File” menu of the Program Man-
ager). In the command line, enter
a:setup
and confirm by clicking on OK.
4. The Setup program’s sign-on message appears. Click
on Continue.
The installation can be canceled at any time by
selecting Exit.
5. A list of installed ISDN-Controllers is then displayed. If
no AVM ISDN-Controllers are installed yet, the entry
“New” (Add an ISDN-Controller) is selected for you.
Click on Continue.
6. Enter the name of the directory in which you want to
install the ISDN-Controller software.
26
3 Driver Software Installation – Windows NT
The default is C:\IDRIVER. You may confirm this or
enter any other directory name. When your entry is
complete, confirm by clicking on OK.
To return to the previous dialog, click on the Go
back button.
7. Select the D-channel protocol used by your ISDN line
(DSS1 or 1TR6). Click on the desired entry, then on
Continue.
8. In the next dialog you must select the I/O address to
be used in the system for the PC interface card.
The first card always uses the I/O address 150.
9. Next, indicate the interrupt level (IRQ) for the PC
interface card.
10. Then enter the Card-ID (board number) of the PC
interface card. This is the number determined by the
DIP switch settings on the card.
If you want to operate several AVM ISDN-Controller
T1s/T1-Bs in one computer, you must first set the
DIP switches on each PC interface card to a unique
card number. See the instructions in Chapter 2,
“Hardware Installation”.
Now the installation routine copies all files to the specified
folder. In the Program Manager or Start menu, you will find
a new program group named AVM. This group contains
the icons T1 Load, T1 Unload, T1 Setup, T1 Test, T1
Readme and AVM Internet Home Page (Windows NT
4.0 only: this is a link to AVM’s Internet site, and requires
Internet access and a WWW browser).
Finally, a message box displays the current configuration
of the ISDN-Controller. Click on OK to acknowledge and
close the window. To complete the installation, Windows
NT must now be restarted.
This done, you may start the AVM ISDN-Controller T1/
T1-B.
27
3 Driver Software Installation – Windows NT
3.2.2 Loading and Unloading the ISDN-Controller
The AVM ISDN-Controller T1/T1-B is installed in Win-
dows NT as a service, and is therefore loaded automati-
cally each time Windows NT is started. This takes place
before programs in the Startup group run, so that you
may include CAPI-based communications programs in your
Startup group if desired.
If you would like to disable automatic loading of the ISDN-
Controller, run the T1 Setup program in the AVM group.
This program allows you to enable and disable automatic
loading, change the D-channel protocol setting and change
the controller’s interrupt and I/O address settings.
To load the Controller manually, click on T1 Load in the
AVM group. When the ISDN-Controller has been loaded,
the following message appears:
Fig. ISDN-Controller sign-on message in Windows NT
To remove the driver software from memory, click on T1
Unload. A message appears to confirm the operation.
28

3.2.3 Installing Additional ISDN-Controllers
If you want to add another AVM ISDN-Controller, start the
T1 Setup program in the AVM group and select the option
New (Add an ISDN-Controller). Follow the program’s in-
structions.
After successful installation, the command T1 Load loads
all the Controllers installed.
3.2.4 Removing the Driver Software
To remove the AVM ISDN-Controller T1 from the Win-
dows NT 4.0 system, open the Windows NT Control Panel
(Start menu, Settings) and double-click on the Add/
Remove Programs applet. The AVM ISDN-Controller
T1 appears in the list of installed programs. Select this
entry and click on Add/Remove. The deinstallation pro-
gram starts.
First select the ISDN-Controller that you want to remove.
The program then indicates which folder contains the
driver software to be deleted. When the deinstallation is
finished, you are prompted to restart Windows NT.
To remove the ISDN-Controller from Windows NT 3.51,
start the Setup program from the installation CD. Setup
reports that an installed ISDN-Controller was detected.
Select the option “Deinstallation”, and follow the instruc-
tions displayed. (This method can also be used in Windows
NT 4.0.)
Only one ISDN-Controller is removed at a time. If you have
installed several controllers and want to remove them all,
repeat the procedure described above as many times as
necessary. You only need to restart Windows NT after the
last deinstallation.

includes all the main components for communication
between ISDN and the host PC. The ISDN-Controller is
connected to the network terminator (NT) and the host
PC. A special high-speed interface is used for the PC
connection.
The ISDN-Controller consists of two functional sub-
systems. One is the ISDN subsystem, which handles
the data transmission to and reception from ISDN and
converts the ISDN data stream into a format that the PC
can process. The other subsystem comprises the
application and control logic.
Data are transferred across the ISDN Primary Rate
Interface using a time-multiplex technique and a pseudo-
ternary modified alternate mark inversion (AMI) coding.
The multiplex time frame is 256 bits long and divided
into 32 slots of eight bits each. Slots 1–15 and 17–31
correspond to the data channels and carry user infor-
mation. D-channel information is transmitted in Slot 16.
In the T1’s ISDN interface, the 30 data channels of the
incoming data stream are handled by a Munich32. An
HSCX is used for the D channel. The ISDN interface is
controlled by the T1’s application and control sub-
system, which consists of a transputer network of at
least three CPUs.
The term “transputer”, a mixture of “transmitter” and
“computer”, refers to a processor that combines pro-
gram execution with fast communication capabilities. A
transputer is a RISC CPU equipped with two or four
special high-speed interfaces called “links”. This CPU
design is ideal for communications applications. The
T1’s CPUs are networked together through their links,
and one link is used for communication with the host
PC.

Fig. Structure of the ISDN-Controller
Two transputers control the B channels and D channel
by means of the Munich32 and the HSCX. The third
CPU is the applications transputer. Furthermore, the
AVM ISDN-Controller T1-B contains another circuit
board, called a booster board, in addition to the T1
motherboard. The booster board carries four addi-
tional T450 transputers and eight megabytes of RAM,
which can be used for applications such as controller-
based V.42bis data compression or DTMF functions.
The T1 housing can accommodate up to three booster
boards.
5.2 The Link Adapter
The link adapter, a plug-in card for the PC’s ISA bus slot,
forms the interface between the host PC and the T1
controller. Data communication between the ISDN-
Controller T1/T1-B and the host PC takes place at a
rate of 20 Mbit/s. Up to four link adapter cards can be
installed in one PC, so that each host PC can run up to
four ISDN-Controller T1s.
