Communications Overview“Barbarians At The Gate”

TM

THE OPINIONS AND VIEWS OF THIS PRESENTER DO NOT NECESSARILY REFLECT THOSE OF ESX, ESA OR CSAA.

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

TM


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

TM


Today’s Communications Choices

• GPRS, EDGE & UMTS labeled 2.5G and 3G

• POTS• VoIP & MFVN• Private Radio• IP and the Internet

TM


Plain Old Telephone Service

POTS

TM


POTS

• Handling alarm signals since late 70’s

• Began changing after the breakup of AT&T

• Fading altogether after 2000

TM


TM


Challenges to POTS

• The expanding use of VoIP

• Increased use of cellular

• Perhaps non-sustainable economically by baby bells

AT&T is loosing 700,000 lines a month

Impact of Wireless

ExampleAt Age 38, Number of Wireless Only Households Quadrupled infive years

Wireless will Dictate SolutionsWireless will Dictate Solutions

TM


New Generation of Customer

• Comfortable with the Internet

• Vast majority have portable devices– Many have multiple portable devices

• This generation will not be tethered

• Demand new applications for their devices

TM


TM


Cellular Technology

TM


Cellular Technology

• Largely used for backup

• But NFPA 72 now allows cellular alone in residential

• AMPS Sunset should have taught a lesson

Challenges to 2.5G &3G

• Competitive forces will move cellular to 4G

i.e. LTE or “Long Term Evolution”

• 2.5G & 3G will be squeezed out in…….

TM


When?

• 3, 5, 7 years???

VoIP

TM


VoIP and MFVN

• Certain versions prove unreliable

• Managed Facilities Voice Networks

Cable’s Digital Voice

Verizon FiOS

AT&T uVerse

TM


Challenges to MFVN

• Not always reliable

• On-premises battery back-up issues

• Still seeing Line Seizure compromises

TM


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!

Major Headache

IP

TM


EoIP

• Everything is moving to IP

• GSM, IP dual path

• The future is IP

TM


The Use of IP

• Provides fast transmission

• Provides “Grade AA” type security at little or no cost

• Can be “wired” or wireless

TM


Challenges to IP and the Internet

• More expensive

• “Last mile” reliability issues

• Battery backup issues

TM


TM


Private Radio

TM


Private Radio

• Two-way radio at 450 MHz.

• Private radio at 900 MHz.

• Cognitive radio

TM


Industry Has Changed

Early on, Early on, Radios used Radios used only for backuponly for backup

Today they Today they represent a broader represent a broader need and an need and an opportunityopportunity

Different World than a Few Years Ago

TM


Challenges to Radio

• Availability of frequencies

• Mesh Networks requires density to be affective

• More skill sets required

TM


TM


The Changing Face of Communications

• The National Broadband Plan

• The Failure of BPL• Google’s Vision• PSST and the “D-Block”

WHICH WILL PREVAIL?

TM


Solutions

• Redundancy

• Flexibility Perhaps in the form of

modularity

• Contractual safeguards

Survey will miss a large segment of the population

Receiver Technology & Carrier Changes

Morgan HertelStephen KovacsissSascha Kylau

TM


The Demise of POT’s

• The Death of POT’s Lines• IP,IP,IP and more IP• UL 1981 update• Software Applications

TM


The Death of POT’s Lines

• AT&T is loosing 700,000 lines a month

• MVFN networks are still not working

• AT&T Letter to FCC• Verizon FIOS update

TM


IP, IP, IP and more IP

• Everything is moving to IP• GSM, IP dual path• Private systems like AES

TM


Receiver Technology

•Receivers changing to IP based•Software receivers•Software receivers vs. Hardware receiver

TM


Receiver Technology

•Incoming IP signals to the station are quicker•The buffering of signals will now be at the receiver and automation•POT’s receivers can output 300 signals a minute to the automation•IP receivers can output 2500 signals a minute

TM


UL 1981 Update

• MEW Levels• Software Receivers• New concepts• New requirements

TM


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.

TM


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.

TM


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

TM


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

TM


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


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?
