Answers

1. a
   
   
2. d – All of these potential problems are possible with VoIP-based systems. In fact, many VoIP providers recommend that if a remotely monitored security system is at the location, the user maintain a POTS line or other form of communication for alarm transmission.
   
   
3. d – Any always-on broadband Internet connection can be used to monitor security systems. Due to the small amount of data transmitted by the burglar alarm control panel, the type of connection has a very limited effect on the throughput of an alarm signal. If you are using the broadband connection to program the alarm control panel, higher speed connections will reduce the time necessary to fully program the system.
   
   
4. a – This false telephone line voltage may cause the alarm control to not alert the user about the communication network’s failure.
   
   
5. b – General Packet Radio Service is a standard for wireless communication which runs at speeds up to 115,000 bits per second. GPRS supports a wide range of bandwidths and is an efficient use of limited bandwidth by having multiple users share the same transmission channel, and only transmitting when they have data to send. It is particularly suited for sending and receiving large volumes of data.
   
   
6. c – If you will be using the PSTN as a backup to the Internet, you also should install a traditional RJ-31X jack for the digital communications.
   
   
7. a
   
   
8. a – When you connect a DVR to a network, it must be programmed with a fixed IP address. Additionally, for remote access over the Internet, a fixed external IP address also is needed, and it may be necessary to open specific ports to view the images over the Internet.
   
   
9. c
   
   
10. b
    
    
11. b – Only one path is required as long as the path and equipment used are listed for the application. Sometimes two different communication technologies are used, such as digital and radio, depending on how the devices are listed.
    
    
12. d
    
    
13. b – Internet monitoring can utilize DHCP for the control panel’s IP address, but the remote monitoring receiver must have a fixed IP address.
    
    
14. b – Although VoIP does require a broadband connection, you can use equipment that employs the broadband connection itself to monitor security systems. These IP-based systems offer many advantages over VoIP systems.
    
    
15. a – True. GSM is one of the leading digital cellular systems in use. GSM differs significantly from its predecessors in that both signaling and speech channels are digital call quality.
