Features
Features
The OpenCom 100 communications
system is designed to be connected
to an ISDN basic access with the
DSS1 protocol. System access (point-
to-point access) and multi-terminal
access (point-to-multi-point access)
are both supported. The two forms
of access can be configured parallel.
For this purpose
■the OpenCom 105 has a total of
four S0ports (one external, one
internal, and two switchable be-
tween internal/external),
■the OpenCom 110 has a total of
five S0ports (two external, one
internal, and two switchable be-
tween internal/external), and
■the OpenCom 120 has a total of
six S0ports, all switchable be-
tween internal/external.
The firmware of the OpenCom 100
is designed for configuring up to
150 users.
You can connect to the
OpenCom 100:
■Euro-ISDN terminals
■DeTeWe system telephones
■DeTeWe RFP 21base stations
■analogue terminals.
The S0port requires Euro-ISDN ter-
minals in accordance with DSS1. The
Upn port is suitable for the Open-
Phone range of DeTeWe system tele-
phones and for the DeTeWe RFP 21
base stations. The analogue port op-
erates with analogue standard ter-
minals.
The OpenCom 100 can be integrated
in an existing network (LAN), and
used by all client workstations as an
Internet access router and mail
client.
Configuration and programming of
the OpenCom 100 is performed by
means of a Web browser (Web con-
sole), which can be run on a con-
nected PC. The OpenCom 100 con-
figuration can also be prepared in
the Service Centre and maintained
by means of remote configuration.
A PC can be connected via a COM
port for the purpose of configuring
the system or transferring connec-
tion data.
In order to connect the OpenCom
100 with the existing hardware in
the building, there are two actor
ports (output) and one sensor port
(input).

4Features
These can be used to operate e.g. a
door opener and a doorbell via the
system (this requires additional de-
vices).
With the OpenCom 100 you can use
the CTI (Computer Telephony Inte-
gration) applications of other manu-
facturers. This requires a TAPI driver
(supplied on the CD) to be installed
on a Windows PC. The OpenCom 100
also has an integrated dialling assist-
ant, the VirtualPhone, with which
users can invoke and use the func-
tions of telephones on PCs, without
installing a special TAPI driver.
The OpenCom 100 complies with the
regulations for telecommunications
equipment. The OpenCom 100 is de-
signed to be connected to ISDN
point-to-point lines at a later time.
Internet Access
It is possible to connect individual
PCs to the OpenCom 100 via the in-
ternal S0ports, or to connect an en-
tire LAN to the OpenCom 100 via the
Ethernet port. These PCs can access
the Internet via the OpenCom 100.
For this purpose, several call-by-call
providers are pre-set on the
OpenCom 100. If Internet access is
already available from an Internet
Service Provider, the OpenCom 100
can be configured for this ISP.
If the client network is not IP-capa-
ble, the OpenCom 100 can adminis-
ter the IP configuration necessary for
Internet access. The OpenCom 100
has an integrated DHCP server and a
DNS server, which in this case then
take over IP address administration
and name resolution for the client
systems.
The OpenCom 100 enables Internet
access for all connected PCs under a
single, mutual IP address. Only this is
externally visible. The local IP ad-
dresses of the client PCs are trans-
lated by Network Address Transla-
tion (NAT) to the IP address of the
OpenCom 100. The client PCs in the
LAN can thus not be reached directly
from the Internet. This protects
them from direct external attack.
The LAN is additionally protected by
the OpenCom 100 filter lists, which
can be customised individually (fire-
wall function).
DECT Data Communication
The OpenPhone 25 DECT terminals
enable PCs that are not connected to
the OpenCom 100 via the internal S0
interfaces or the Ethernet interface
to access the Internet. These PCs can
make full use of all the Internet and
e-mail features of the OpenCom 100.
Data is transmitted via the internal
data interface of the OpenPhone 25,
which must be connected to the se-
rial interface of the PC by means of
an adapter. The Internet can then be
accessed directly via the remote data
transfer network or indirectly via
RAS access on the OpenCom 100.

5
Features
The Internet connection through the
OpenPhone 25 is established as a
data connection via the DECT air in-
terface with the OpenCom 100.
For detailed information on the in-
stallation of the required driver soft-
ware and the different configura-
tion modes, please refer to the
“OpenPhone 25” user guide. For in-
formation on the configuration of
the OpenPhone 25 with data inter-
faces, refer to the online help of the
OpenCom 100.
E-mail
The OpenCom 100 has an integrated
e-mail function which is able to use
the POP3, APOP or IMAP4 protocols
to check the Internet Service Pro-
vider for incoming mail. A mail
account enquiry can be configured
for every member of staff (OpenCom
100 user).
The OpenCom 100 then fetches the
incoming e-mail headers (subjects)
and senders from the mail server at
set intervals, and forwards them to
users with system terminals.

Authorisations
The use of functions by a terminal on
the OpenCom 100 is regulated by
means of authorisations. These au-
thorisations are configured for user
groups, to which the users with their
terminals are then assigned.
Two user groups are preset: “Admin-
istrators” and “Guests.” “Administra-
tors” have access to all functions of
the OpenCom 100 and unrestricted
configuration rights. Users in the
“Guests” group cannot configure the
OpenCom 100, are not permitted to
make external calls, and have only
restricted use of the terminal func-
tions of the OpenCom 100.
Note: When the OpenCom 100 is
commissioned, all connected devices
are at first in the “Administrators”
group until an Administrator pass-
word is entered. Subsequently, all de-
vices are automatically in the
“Guests” group (see also the chapter
Configuring the OpenCom 100 start-
ing on page 31). For more details on
the configuration of user groups,
please refer to the online help in the
chapter “User Manager.”
The following terminal functions are
factory preset to the “Administra-
tors” group:

S0Ports
Whether you use the switchable
S0ports for internal or external com-
munication depends on your com-
munications requirements and the
existing basic accesses.
Please note that the S0bus requires
a terminating resistor. Resistors in
the OpenCom 100 and OpenCom
120 are marked with an R in the
diagram Positions of the Ports on
page 15, and are realised as gravity
hooks. Open the switch if you do not
wish to terminate the bus with the
OpenCom 100 but at its ends.
In the case of the OpenCom 105, the
S0buses are terminated by software.
You make this setting in the S0 port
configuration in the Configurator
on the Web console.
You can connect up to eight termi-
nals on every internal S0bus; up to
three of the terminals can operate
without an external power supply.
The length of the four-wire cable of
an internal S0bus must not exceed
150 m. The power consumption of
each internal S0bus is approx. 3 W.
The S0bus is terminated at one end by
the OpenCom 100; the gravity hook is
closed.
IAE=ISDN connection unit (“ISDN
socket”) or an ISDN device.
TR= terminal resistor, the S0terminat-
ing resistor. The TR must be at the ter-
mination of the line. This can also be
done by means of a correspondingly
switched IAE.
The S0bus is terminated by means of
the TR at the ends: the gravity hook is
open.
Upn Ports
The Upn ports enable the connection
of one DECT base station each, or an
OpenPhone 61, 63 or 65, by means
of a twin-wire cable.

The maximum permitted length of
the twin-wire Upn bus cable is
1,000 m, when 0.6 mm cable
(twisted pair) is used. The power
consumption of each Upn bus is
approx. 3 W.

Upn Adapter
The Upn adapter is designed for use
with the system telephones
OpenPhone 63 and OpenPhone 65.
If you operate an OpenPhone 63 or
OpenPhone 65 system telephone on
a Upn port, you can then connect a
further OpenPhone (61, 63 or 65) to
this telephone via a Upn adapter.
a/b Ports
The a/b ports are for operating ana-
logue devices (fax, modem or ana-
logue telephone). The maximum
permitted length of the twin- wire
cable is 1,000 m, when twin-wire 0.6
mm cable (twisted pair) is used.
If an entrance intercom system is
connected to a/b1, the switch
marked “E” on the diagram Positions
of the Ports starting on page 15 must
be open in order to decouple the low
frequency voltage from the supply
(see also the following section,
Actor/Sensor on page 17).
Actor/Sensor
In order to operate an entrance in-
tercom and door opener, you need
four twin-wire cables:
■one cable between the entrance
intercom and the a/b1 port,
■one between the door opener
and the Actor1 port (marked In-
tercom/Door opener in the dia-
gram Positions of the Ports start-
ing on page 15),
■one between the intercom input
and the Actor2 port (marked In-
tercom/Relay in the diagram Po-
sitions of the Ports starting on
page 15) to activate the ampli-
fier,
■and one between the doorbell
and the sensor port.
Only use entrance intercoms and
door openers complying with FTZ
Guideline No. 123D12.

LAN Port
The LAN port (OpenCom 120: LAN 1
port) enables the integration of the
OpenCom 100 in an existing in-
house LAN by means of a 10-Mbit
hub.
The LAN cable must not exceed
100 m in length.
The second LAN port of the
OpenCom 120 is intended only for
networking two OpenCom 120/120
or 110/120 systems.
DSL Port
Connecting the OpenCom 100 to the
network via ISDN and DSL
The LAN port is also intended for
leading the DSL port to the router.
With the OpenCom 100, the output
of the DSL modem (NTBBA) is led to
the LAN port of the OpenCom 100
(LAN 1 in the case of the OpenCom
120) via a switch or hub. The router
subsequently converts the PPPoE
protocol to the TCP/IP protocol of
the LAN.
The connection of the DSL modem
is via a crossover twisted pair cable.
If so desired, you can also use a
switchable port on the hub, which is
usually indicated by an “X.”
PCM Port
The PCM port is used to connect two
OpenCom 120 systems, or an Open-
Com 110 with an OpenCom 120
system by means of a special trans-
mission method called Pulse Code
Modulation. The RJ-45 cable used
must not exceed 4 m in length.
Sync Port
The twin-wire Sync port is used
when the OpenCom 100 functions
as a sub-system for a main system,
which is a DECT system.
