Description
Introduction
The Doortello Business is a door phone system for integration with new or existing
telephone systems. The door phone has a analogue telephone line interface a can
be connected to any type of transmission technology, as far as a specific adapter is
available, like ISDN, VoIP, GSM, DECT and similar systems. Pressing a chime button,
or dialling a number using the key pad, a programmed telephone number, or the
dialled digits, are sent as DTMF tones to the telephone line. Up to 127 chime
buttons can be connected to the system. Each of them can have a 16 digits long
telephone number stored in the system. When the dialled extension will answer
the call a speech connection is established. A smart tone detection program
ensures that the connection is surely terminated recognizing a busy tone, or in
case of a missing answer after a specified number of ring back tones.
The door phone is approved for the use within the European community as
defined by the 98/482/EU (TBR 21) on the analogue telephone network. This is not
a warranty that the device can work with all European telephone networks, which
might slightly differ from the standard.
If you notice functional problems with your telephone line please get in contact
