Initial operation
Connection to tiptel 3011 / 3022 office / system
As system terminal unit, the tiptel 83 system should only be operated with an internal phone
number. The phone number has to be entered according to the instructions on page 27
(entering the MSNs). Further internal phone numbers (up to 6) can however only be used for
group and team calls. The system functions (exception: internal target or line key) exclusively
refer to the subscriber number entered first (MSN1).
Information for the administrator of the telephone system: In order to use the system functions,
the telephone system must at least be equipped with firmware version V 1.36. If necessary, an
update has to be carried out. After connecting the device to an internal S0 bus of the telephone
system, the system telephone is automatically identified and can be configured under the menu
option "subscriber". At this respect, please also consider the corresponding information in the
installation instructions of the telephone system.
Emergency operation
The tiptel 4011 XTprovides power supply for your telephone in the case of power failure, pro-
vided that the tiptel 83 system is connected to the internal ISDN access on the mainboard of the
tiptel 4011 XT. This will only work for one terminal as a maximum. Should a further terminal be
connected to the internal port, the switch for emergency power feeding of this terminal must be
set to position "OFF"!
In the case of a power failure, the telephone system tiptel 4011 XT connects the external ISDN
access to the internal access on the mainboard. The emergency power feeding will only work
properly provided that the external ISDN access is a point-to-multipoint access.
In the case of a power failure, the exchange office provides a remote power feeding for the
emergency operation of one terminal as a maximum. If you want to use your tiptel 83 system as
emergency telephone, you have to set the switch for emergency power feeding to
position "ON".
Please be aware that the telephone functions are restricted during emergency operation. The
following functions will then not be available:
