Systematic Telephony
The OpenCom 100 communications
system, referred to hereafter as “the
OpenCom 100”, enables the connec-
tion of standard terminals (standard
analogue telephones, ISDN tele-
phones and cordless GAP tele-
phones). SMS-enabled terminals can
also be used. With this configuration
you can telephone conveniently and
use the features of the
OpenCom 100 via code-number pro-
cedures.
This guide describes how you oper-
ate your telephone in order to use
the desired functions. In most cases,
you can do this by pressing the key
combination
* and #, R , to-
gether with a specific sequence of
digits.
Please note the specific operating
characteristics of your telephone:
On standard analogue telephones
featuring pulse dialling, it is not pos-
sible to enter data with the star key
* or hash key #.
As a result, the functionality of the
OpenCom 100 features is only availa-
ble to you on a limited basis. It is
thus better to use telephones
equipped with dual-tone multi-fre-
quency (DTMF) dialling. Modern tel-
ephones often allow you to switch
between the two dialling modes.
In the case of ISDN telephones, cer-
tain features can be operated via
menus or function keys. Refer to the
operating instructions of these tele-
phones for details.
On telephones with a display, you
can read the caller’s telephone
number if the telephone supports
this feature and the caller has acti-
vated it. What other information is
displayed depends on the tele-
phone. Charge display (ISDN tele-
phones only) requires prior configu-
ration by your network operator.
You Need Authorisation
Most of the features mentioned in
this Quick Reference Guide are only
available to you if you have appro-
priate authorisation. This will be set
up by your system administrator
when configuring the
OpenCom 100. If you are unable to
use a particular feature or have any
questions, consult your system
administrator. Please refer to the
chapter entitled “Frequently Asked
Questions” in the “Mounting and
Commissioning” user guide for tips
on how to deal with any faults you
may experience while using your tel-
ephone.
