Wired History
• Pre-1980 Largely copper-centric with some voice-grade
connectivity
• Post-1980 Emergency of the Digital Communicator
(DACT) revolutionized the alarm industry
• 2001: IP (indirectly) written into NFPA 72
• About the same time: VoIP begins to disrupt the DACT’s reign
• 2009 MFVN written into NFPA 72

Wireless History
• 1969 CSEPA (CSAA’s processor) gains exclusivity from the FCC on 5 pairs of 450 MHz business band voice channels
• 1985 One way radio written into NFPA 72
• 1990 Two way radio written into NFPA 72
• 1985 CSAA gains right to coordinate offset between these frequencies and has “the 20 foot rule” amended
• 1992 First use of control channel signaling on AMPS cellular
• 2008 AMPS Sunset

Challenges to 2.5G &3G
• Competitive forces will move cellular to 4G
i.e. LTE or “Long Term Evolution”

VoIP and MFVN
• Certain versions prove unreliable
• Managed Facilities Voice Networks
Cable’s Digital Voice
Verizon FiOS
AT&T uVerse

Challenges to MFVN
• Not always reliable
• On-premises battery back-up issues
• Still seeing Line Seizure compromises
TM
THE OPINIONS AND VIEWS OF THIS PRESENTER DO NOT NECESSARILY REFLECT THOSE OF ESX, ESA OR CSAA.
VoIP Remains a Problem
• Not as reliable as POTS– Managed providers are good but not great!
• e.g., cable company based services
– Non-managed providers are not good• e.g., Vonage, AT&T CallVantage, Verizon
VoiceWing
• No FCC or industry standards• Significant growth continues
– End-user saves money with VoIP– Excellent voice quality and features
At Risk – Your Liability and RMR!
You may never know a problem exists ifyou don’t send test signals on your systems!

What is IP?• Internet Protocol (IP) - It is a protocol used for
communicating data across a packet-switched internetwork using the Internet Protocol Suite.
• It is the primary protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering data packets from the source host to the destination host based on their addresses. The Internet Protocol defines the addressing methods and structures for datagram encapsulation. The primary version of addressing structure used is referred to as Internet Protocol Version 4 (IPv4), although the successor, Internet Protocol Version 6 (IPv6) is being deployed actively worldwide.

What is VoIP?• Voice over Internet Protocol (VoIP) -
describes a family of transmission technologies for delivery of voice communications over IP networks such as the Internet. VoIP is known in common applications like Digital Phone, Vonage, and Skype.

Why is VoIP a problem?• Manipulation of DTMF tones
– “Good” Contact ID report session
– Contact ID report session over VOIP
• Elimination of standard phone line– Disables line seizure– Can disconnect panel completely

Using IP for alarm signaling• Using IP for Alarm signaling can happen in different
ways• Many alarm signals today get converted to IP to reach
a location even though the transmitting and receiving ends of the alarm signal are connected to POTS
• Supervision of an alarm panel can be accomplished when using IP signaling
• Alarms can be received much quicker when using IP for communication than over traditional POTS
• Typical IP alarm transmission takes 2 seconds maximum from transmitter to receiver. Typical alarm transmission using POTS is about 15 seconds if a fast format is used or 30 seconds if a pulse format is used

UDP vs. TCP transmissionsWhat is the difference?
UDP: User Datagram Protocol• Connectionless• Delivery guaranteed by the application• Less bandwidth• Requires NAT/PAT support
TCP: Transmission Control Protocol• Connection oriented• Delivery guaranteed by the network• Higher bandwidth• Requires NAT to establish connection
TM
THE OPINIONS AND VIEWS OF THIS PRESENTER DO NOT NECESSARILY REFLECT THOSE OF ESX, ESA OR CSAA.
UDP vs. TCP transmissions
UDP: User Datagram Protocol• Equipment must support NAT / PAT• NAT: Network Address Translation• PAT: Port Address Translation• Replies must be sent to Source Port
TCP: Transmission Control Protocol• Only require NAT Support• PAT is handled by the TCP connection
NAT / PAT: What is the difference?
NAT - Network Address Translation Used to translate an IP Address from one network to another Typically used from a private LAN to the Internet
PAT - Port Address Translation Used in association with NAT to direct packets to appropriate devices Allows multiple devices to be on LAN using same destination port
NAT / PAT: Why does it matter?
