Preliminary
3.2.1
The SLICOFI-2x offers programmable DTMF generation for both channels by using the
internal tone generators.
3.2.2
Both channels (A and B) of the SLICOFI-2 device have a powerful built-in DTMF decoder
that will meet most national requirements. The receiver algorithm performance meets the
quality criteria for central office/exchange applications. It complies among others with the
requirements of ITU-T Q.24, Bellcore GR-30-CORE (TR-NWT-000506) and Deutsche
Telekom network (BAPT 223 ZV 5, Approval Specification of the Federal Office for Post
and Telecommunications, Germany).
The performance of the algorithm can be adapted according to the needs of the
application via the digital interface (detection level, twist, bandwidth and center
frequency of the notch filter).
