The CMC-TC ISDN unit can be used to configure a redundant transmission path or,
when no network infrastructure is available, for relaying alarm messages. The alarm
signal is sent in SMS format. The ISDN unit is connected to the serial interface on the
processing unit 7320.100. The power supply is likewise achieved via the connection
cable. The device functions only with ISDN (see “ISDN access – minimum
requirements”). Up to four target call numbers may be set and allocated to the
various events.
This variant of sending alarm messages can also be used for countries permitting
SMS in fixed networks. Moreover, SMS can now be used over the fixed network to
control switching outputs.
Power supply is via the processing unit.
Other functions, where offered by the provider:

- Fax

- E-mail:

- Voice mail

ISDN access – requirements:

- DSS1 (Euro-ISDN)

- Point-to-multi-point configuration (ISDN-S

-Bus)

0

These minimum requirements must also be fulfilled when the ISDN unit is connected
to a private branch exchange.

Important information:
– IMPORTANT Only one of the tools “ISDN unit”, “GSM unit”, or “display unit” may be

connected to a PU.

– IMPORTANT When the ISDN unit is used, the front interface

(RS-232) on the processing unit is deactivated (e.g.
Hyperterminal access). The system can then be configured only
via Telnet or the web.
When Hyperterminal was used before the ISDN unit is installed, the
user must have logged off correctly.

– IMPORTANT When the system is used outside of Germany, it must be
reconfigured to the new circumstances over a telephone link. Our centre will be

pleased to assist you with further information.

Tel.: (+49) (02772) 505 – 2578

– IMPORTANT When more than sixteen unsent messages have accumulated in the
SMS memory, all new outgoing messages will be deleted. These deleted messages
can be viewed in the Processing Unit via the WEB or FTP.

The provided RJ12/RJ12 connecting lead connects the ISDN unit to this RJ12 socket (RS-232
interface) on the processing unit. This connecting lead functions as the 24 V DC supply and
transfers data to and from the processing unit.

The RJ45 ISDN socket is designed for connection to an ISDN socket.

6. First start-up

PIN GSM-Card:

Note: Phone Number 1 - 4

Important: The following description applies to software version 1.21 and higher for
the processing unit (DK 7320.100) needed to operate the ISDN unit.

§ First start-up

When several SMS terminals are operated on the one ISDN bus, each of these SMS
terminals (and therefore every ISDN unit as well) must be assigned its own call
number for sending and receiving SMSs.

Note the following before transferring SMSs over the fixed network.
(This is necessary only when an SMS command is to be sent to the ISDN unit.

Receiving SMS “alarm” messages does not require registration. )

Registering at a network provider requires that an SMS is sent once only to this
provider (for example for Deutsche Telekom: the text “ANMELD” is sent to the call
number “8888”). See the section “ISDN command” below.

The following data must be entered before the ISDN unit is connected to the
processing unit.

Mandatory data:

This field is not needed to configure the ISDN
Unit.

Service Center GSM:

This field is not needed to configure the ISDN
Unit.

Mobile phone numbers must not
entered with the country code.

ISDN MSN:

The MSN (multiple subscriber number) is assigned by the network provider.
Also the country code and the local area code must be entered (separated by “/”).
Example: +49/2772/570126

ISDN Command

Before an SMS can be sent over the fixed network, the ISDN unit must be registered
at an SMS centre. (This is necessary only when an SMS command is to be sent to
the ISDN unit. Receiving SMS “alarm” messages does not require registration. )
The Deutsche Telekom SMS Centre requires an SMS containing the text “ANMELD”
to be sent to the number 8888.

Enter “8888 ANMELD” in the field “ISDN Command”. The ISDN unit then sends this
message to the SMS centre.

When the ISDN unit is not to receive SMS messages any longer or is to be operated
at another socket, the command “8888 ABMELD” sent to Deutsche Telekom cancels
the registration.
