DTMF decoders can be switched on or off individually to reduce power consumption. In
normal operation, the decoder monitors the Tip and Ring wires via the ITAC pins
(transmit path). Alternatively, the decoder can also be switched in the receive path. On
detection of a valid DTMF tone pair, SLICOFI-2 generates an interrupt via the
appropriate INT pin and indicates a change of status. The DTMF code information is
provided by a register that is read via the digital interface.
The DTMF decoder also has excellent speech-rejection capabilities and complies with
Bellcore TR-TSY-000763. The algorithm has been fully tested with the speech sample
sequences in the Series-1 Digit Simulation Test Tapes for DTMF decoders from
Bellcore. The characteristics of DTMF detection can be controlled by POP registers 30h
to 39
2.8.2
A generator to send calling line identification (Caller ID, CID) is integrated in the
DuSLIC-E/-E2/-P chip set. Caller ID is a generic name for the service provided by
telephone utilities that supply information such as the telephone number or the name of
the calling party to the called subscriber at the start of a call. In call waiting, the Caller ID
service supplies information about a second incoming caller to a subscriber already busy
with a phone call.
In typical Caller ID systems, the coded calling number information is sent from the
central exchange to the called phone. This information can be shown on a display on the
subscriber telephone set. In this case, the Caller ID information is usually displayed
before the subscriber decides to answer the incoming call. If the line is connected to a
computer, caller information can be used to search in databases and additional services
can be offered.
There are two methods used for sending CID information depending on the application
and country-specific requirements:
•
•
DuSLIC-E/-E2/-P contains DTMF generation units and FSK generation units that can be
used for both channels simultaneously.
The characteristics of the Caller ID generation circuitry can be controlled by POP
registers 00
Preliminary Data Sheet
If the pause is followed by a tone pair with the same frequencies as before, this is
interpreted as drop-out.
If the pause is followed by a tone pair with different frequencies and if all other
conditions are valid, this is interpreted as two different numbers.
