Subscriber Line Interface Circuit Control
Havran, Josef ; Číž, Radim (referee) ; Sysel, Petr (advisor)
The aim of this thesis is to design a connection of the development kit for the subscriber line interface circuit Si3220 with the development kit for the digital signal processor DSP56858EVM and implement a test application, which will allow us to use the development kit as a small private branch exchange. The application allows us to operate up to ten telephone machines and it disposes of basic telephone exchange functions -- generating tones to the headphone, detecting the DTMF dialing, generating the ringing and the voice connection of the subscribers.
