Question

What is the value of the signaling tone database which signals call termination by the subscriber?
1. 100 kbps
2. 10 kbps
3. 40 kbps
4. 20 kbps

Answer 1

Correct Answer - Option 2 : 10 kbps

Explanation:

• A frequency is the most basic building block of a call progress tone pattern. A tone is a combination of frequencies, or it is a single frequency that has been designated as a tone. The frequency or frequencies in a tone have specified dBm levels. A tone pattern is a single tone or a sequence of tones, divided at precise intervals by silence.
• A composite cellular terminal providing various service options issues different call termination alert tones and different call termination display messages according to types of terminated calls. The cellular terminal sets and stores the call termination alert tones and the call termination displays messages according to those service options which are available for the composite cellular terminal.
• Upon reception of a paging message, If the terminal recognizes the service option contained within the paging message, the terminal then retrieves a call termination alert tone corresponding to the recognized service option and generates the call termination alert tone.
• The terminal then retrieves a call termination display message corresponding to the recognized service option and displays the read call termination display message.
• The value of the signalling tone database which signals call termination by the subscriber is 10 kbps
