Analogue telephones
Analogue telephones must comply with the following specifications:
•
DTMF telephones (dual tone multiple frequency):
The dialling information is transmitted via a tone sequence. In addition to the
keys
-
and , also the keys "*" and "#" are available.
Additionally the following feature should be supported by the analogue telephones in
order to ensure full capability of the telephone system:
•
CLIP function (calling line identification presentation):
Telephones able to display the phone number of the calling party.
Note: Pulse dialling telephones are NOT supported.
ISDN telephones
Telephones which can be operated at S0-ports according to Euro ISDN standard
DSS1.
For operation of an ISDN telephone, the relevant internal phone number (MSN) is required. Please consult the User's Manual of the ISDN telephone for the programming
procedure.
First steps
15
First steps
This telephone system has been designed as a plug & play device, i.e. after connecting the terminals, connecting the telephone system to the telephone network and
switching on the power supply, the system is ready for use.
Please note that there is a difference between the configuration of a telephone system e.g. by the administrator and a configuration by individual subscribers. The administrator assigns phone numbers to the subscribers. With this phone number or
with the subscriber’s name and a password, the subscriber can enter his personal
settings via a browser (e.g. programming a call forwarding). The administrator also
takes care of the extensions, at which a call will be signalled, and which external
MSNs will be available.
Your telephone system is supplied with the following factory pre-set parameters (The
following list is not complete and includes only the settings relevant for an initial functional test):
•
The external S
0
is configured for Euro ISDN point-to-multipoint and point-to-point
access (DSS1).
•
S
0
ports 2 and 3 are configured via hardware jumpers on the internal S0. The
subscribers (MSNs) 20 – 21 respectively 30 – 31 are pre-set (only tiptel 3022 office).
•
The internal S
0
is configured for Euro ISDN point-to-multipoint access. The sub-
scribers (MSNs) 40 - 41 are pre-set.
•
The analogue extensions 1 – 8 are assigned to the subscribers 50 - 57.
•
All subscribers have international exchange authorisation.
•
Standard exchange connection with the digit
.
•
Charges are only displayed on ISDN terminals, not on analogue terminals.
•
The pre-set PIN is 0000.
•
The pre-set Ethernet address is 192.168.1.100.
•
The pre-set subnet mask is 255.255.255.0.
•
The DHCP start address is 192.168.1.10.
•
The user name / the password for the web-based configuration is admin/admin.
In order to ensure a complete functionality of the ISDN terminals, an MSN must be
assigned to them. For details on assigning MSNs to the ISDN terminals, please
consult the User's Manuals of your ISDN terminals.

Computer setup
Please note that the following information refer to PCs on which one of the following
Microsoft operating systems has been installed: Windows 98, Windows 98SE (second edition), Windows ME, Windows 2000, Windows NT, or Windows XP. But of
course the use of other operating systems – e.g. Apple Macintosh – is also possible
without entailing any problems.
Network configuration
In the factory default setting, the telephone system tiptel 3022 office / tiptel 3011 office acts as DHCP server (Dynamic Host Configuration Protocol) for the connected
computers. In this setting connected computers obtain the necessary IP addresses
automatically.
In case of a newly-installed operating system or a new plug-and-play PC, the necessary PC settings have already been done. In case of PCs which have already been
part of a network and/or have already been configured for Internet access via a DSL,
ISDN, or analogue modem, some of the settings must be undone. These necessary
amendments for the a.m. operating systems are described in detail in the following
chapters.
Note: If any kind of access software has been installed, this has to be uninstalled
first!
If the TCP/IP protocol has been deleted because of installing another
access software, it must be re-installed by means of your Windows CD.
Necessary web browser settings (all operating systems)
If an Internet access has already been programmed on your PC, you have to undo
one web browser setting as a first step.
First click on “tools” in the Internet Explorer, then point to “Internet options...” and
finally click on the “connections” tab. Here you check the option box “never dial a
connection”.
Please proceed accordingly if you use any other browser, and if this setting option is
available. The browser must be configured in a way that no (standard) connection
will automatically be dialled upon starting.
