VII. FUNCTIONAL DESCRIPTIONS
Call Waiting service works by alerting a customer engaged in a telephone call to a new incoming call. Thus, the
customer can still receive important calls while engaged in a current call. The call waiting decoder can detect alert
tone (Call-Waiting Alerting Signal 2130Hz plus 2750Hz) and generate a valid timing on the data pins.
The call waiting decoder is designed to support the Caller Number Deliver feature, which is offered by regional
Bell Operating Companies. The call waiting decoder has four blocks, including OP Amp, band pass filter, and
detection block.
In a typical application, this IC receives Tip/Ring signals from twisted pairs. The signals as inputs of single-ended
pre-amplifier (OP Amp and Buffer Amp), and the amplifier sends input signal to a band pass filter. Once the
